iPhoneMirror: the free iPhone screen mirroring nobody had done well on Windows, built by a Chinese developer to 1700 stars in four months
What it is A free, open-source Windows app. Plug in an iPhone or use AirPlay, and the picture and sound are mirrored to your PC. It can mirror several devices at once, supports mouse reverse control, and can be captured directly by OBS for streaming or recording.
Why it took off For years there was demand for free iPhone mirroring on Windows that no one met. It turned the hardest parts, the private USB protocol and drivers, into a finished product an ordinary person can install. HelloGitHub, GitHubDaily, software-sharing blogs, and Chinese cracking forums passed it along round after round, and dozens of stars stacked up each time.
C How you could follow it Don't build another Windows iPhone mirroring tool. Learn from how it found its gap: look for places where Android or Mac has a free standard but iPhone or Windows only has paid software, build the hardest layer into a finished, installable product, and go through the Chinese distribution chain of cnblogs posts, HelloGitHub, and software blogs.
- Data (updated daily) · Repo created 2026-07-11 · 1,732 stars · 7 days +105
GitHub · stars Data 2026-10-09 → 2026-11-08 (31 days, 14 observations). Points before 10-28 come from deeply / archive backfill, not every day has one
On the evening of 2026 Jul 28, a developer called RayrenSX posted two articles on Cnblogs in a row, with titles that read like they were written for search engines: "iPhoneMirror: iOS multi-mode screen mirroring ios投屏windows iphone投屏windows". As of today, the two pieces have only about 1500 reads combined. But the GitHub repo he created on Jul 11 has 1721 stars and 131 forks as of Nov 6, and the installer has been downloaded about 83k times. It never blew up in a single day. It was passed along, step by step, by Chinese open-source recommendation accounts and software-sharing blogs. This piece covers what gap it filled, where the stars came from, and whether you can still do the same.
A reply that says "this is how I've been making do too"
In Oct 16, the Chinese open-source recommendation account GitHubDaily posted:
I use an iPhone and a Windows PC, and wanted to mirror my phone screen to the computer for demos or tutorials. I found iPhoneMirror, an open-source Windows mirroring tool by chance… The most practical part is that the standalone window has no extra UI, so OBS can capture just that window. For streaming or recording phone tutorials it saves cropping out the control panel.
Someone replied: "Recording iPhone tutorials on Windows really is a pain. AirPlay audio always lags. I used to make do with a cable and the OBS plugin, but the frame rate drops when it goes high."
That comment is the need. Apple's "iPhone Mirroring" is only for Mac; Microsoft's "Phone Link" can only show notifications and texts from an iPhone, not mirror the screen. Mirroring tools on Windows are either paid software requiring memberships and sign-ups, like Aisi Mirror, AirServer, Reflector, and ApowerMirror, or open-source small tools that only work wirelessly over AirPlay. On Android, scrcpy (150k+ stars) had long been the free standard; on iPhone, that spot was still empty.
What it is
A free, open-source (GPL-3.0) Windows 10/11 app: plug an iPhone or iPad in with a USB cable, or use AirPlay on the same local network, and both picture and sound are sent to the computer. Decoding happens locally, with no cloud, and the frame rate is capped at 120. Several devices can be mirrored at once, each in its own window, and the windows have rounded corners matched to each model, so the notch and Dynamic Island outlines line up. The window without extra UI can be captured directly by OBS for streaming or recording. Later it added reverse control over Bluetooth and the developer channel, so you can tap the phone with your PC mouse and keyboard.
The hardest part is the USB layer. Wired mirroring uses Apple's undocumented Screen Capture private protocol, which requires a libusb driver and has to coexist with the Apple Mobile Device driver from iTunes. This is where most similar open-source projects get stuck. In 2019 someone wrote this protocol up as a Go library (quicktime_video_hack, 638 stars), but it was for developers, not a finished product. iPhoneMirror made driver installation, repair, and uninstallation into a separate driver manager, and the installer bundles its runtime, so an ordinary user can download it, install it, and use it.
How the stars accumulated, bit by bit
| Timeline | star | What happened back then |
|---|---|---|
| 07-11 ~ 09-06 | 0 → about 218 | A preview version was released the day the repo was created, and about 45 versions shipped over two months; the author posted seed articles on cnblogs and opened a QQ group |
| 09-06, 09-07 | +115 in a single day (the highest of the whole period) | v1.8.3 released; this version has been downloaded 43,598 times to date; issues began appearing densely from this day. Who drove this wave wasn't found (inference: it entered GitHub's C# trending list) |
| 09-22 ~ 09-24 | +32 and +38 in single days | The software blog "小羿" published "How do you control an iPhone wirelessly from Windows?", which was reposted by "下1个好软件" and Jam's Blog, with a cloud-drive download link attached |
| 09-28 | +87 that day | Included in issue 126 of the HelloGitHub Monthly |
| 10-02 ~ 10-07 | Daily +15~25 | Lao Ai Po Jie original section reposts (1472 views, 19 replies); a long post on X and Zhihu: "iPhoneMirror / rPlayHub: which one is closer to an iOS scrcpy?" |
| 10-16 | 1305 | GitHubDaily recommendation |
| 10-28 ~ 11-06 | 1568 → 1714 | Steady +15~24 per day, +117 over the last 7 days; 11-05 ranked #7 on GitHub's C# daily chart and #12 on the monthly chart |

A few things worth noting:
Downloads far outnumber stars. Cumulative downloads across all versions are about 83k, roughly 50x the star count (this includes repeat downloads from the in-app auto-updater, so it isn't 83k individual people). Almost every software blog links to Quark or Baidu Netdisk, and those users never go to GitHub to star anything. It's a tool people use, not a project people bookmark.
Each channel brings only dozens of stars. The HelloGitHub issue with +87 was already the second-best day. It had no Hacker News or Reddit hits and no press coverage; the English-speaking world has one YouTube video with 281 views and a few scattered Instagram and Facebook shares.
People really use it. Nearly all of the 80 issues are compatibility reports tied to specific models and OS versions: iPhone 17 Pro Max blue screens, iOS 27 handshake timeouts, black iPad screens, and Sogou input method reverse control that can't type. The community has built its own Linux and HarmonyOS PC ports, which the author credits in the README. The author of QtScrcpy (with 30k+ stars) also forked it.
Who it's competing with
| Who | What it is | Compared with alternatives |
|---|---|---|
| Apple iPhone Mirroring | Built into macOS since 15 | Mac only |
| iSi Screen Mirror (Aisi Touping) | Commercial software with a large installed base in China | Core features require a membership and tie you to the Aisi ecosystem; iPhoneMirror even includes an "Aisi compatibility mode" |
| AirServer, Reflector, ApowerMirror, AirDroid Cast | Long-established paid software | Most only use AirPlay, and reverse control requires a subscription |
| UxPlay family (3.3k / 2.2k stars), uxplay-windows (849) | Open-source AirPlay receivers | Wireless only, with no USB, reverse control, or multi-device UI |
| rPlayHub (2026-08,73 stars) | Open-source "iOS scrcpy" | Handles both viewing and control, but targets macOS / Linux and doesn't serve Windows users |
| AirPlayServer, pcairplay, mirror-me, 1PhoneMirror, and others | Small open-source libraries released in 2025–2026 | All handle only the AirPlay layer, and most sit at single-digit to low-hundreds of stars |
On Windows, it is currently the only free, open-source option that puts USB wired, wireless, reverse control, and multi-device support in a single installer.
Name-squatters have appeared too: iphonemirror.cn (landing page live since Sep 17) uses the same name for a "Pro" landing page, also labeled "v1.8.3", claiming "one license for Win/Mac", and features testimonials from "Bilibili teacher Lin" and "Douyin gaming streamer Xia Xiaoman" that look fabricated, with downloads via Quark. Who runs it and whether it actually takes payments is unverified, but it shows someone thinks this demand can be monetized.
Why it's taking off
- The demand is old, clear, and went unmet for free for years. Windows PC plus iPhone is the most common combination in China. Recording tutorials, streaming mobile games, demoing apps, and testing several phones at once all require screen mirroring, and "how to mirror an iPhone to Windows" questions recur every year.
- It solved the hard layer. Open-source wireless AirPlay implementations are everywhere. The barrier is the private USB protocol plus drivers, and that's what others couldn't easily copy.
- It can be explained in one line: "an iPhone version of scrcpy." Recommendation posts almost all say "on Windows, free and open source, plug in and mirror, and you can control it too"; blog titles use reverse control as the selling point.
- Details give recommenders something to write about. Device corner radii, Dynamic Island outlines, a windowless window for OBS, and 120 frames per second are the things the GitHubDaily original highlights.
- One person, fast releases, Chinese-language focus. About 45 releases in two months, quick issue responses, a bilingual README, and QQ group support. Of 216 commits, 188 came from the author.
If it were you
C. That spot is already taken, and the barrier is the private protocol and drivers. Building another Windows iPhone mirroring tool would most likely land at AirPlayServer or mirror-me levels, a hundred or two stars. What's worth learning is how it found the gap: Android has an open standard and iPhone doesn't; Mac has a built-in feature and Windows doesn't. In places like that, the hardest layer gets turned into a finished product an ordinary person can install.
Who it suits: Windows or low-level developers who understand USB, drivers, and audio/video decoding and can handle a private protocol; people willing to ship dozens of releases in two months and answer issues daily, as it does.
Who it doesn't suit: people who only know how to build AirPlay receivers and want to add a UI layer on top (there are plenty of these, and none took off); anyone wanting to build a paid version, since the GPL license plus the iUsbBridge reverse-control dependency is restricted to non-commercial use, and name-squatters are already on that path; anyone who only wants a "Linux" or "HarmonyOS" version, since community ports already exist and the author has already given them a place in the README.
How to approach it: if you go after this, target the parts it hasn't done well. Three visible gaps: Windows ARM64, which it explicitly doesn't support (the drivers and wireless runtime have no ARM64 build); almost nobody in the English-speaking world knows about it; and every iOS update can break the private protocol (iOS 27 already produced handshake timeouts), with the whole project resting on one person. Even better is to find a different gap of the same shape: list the cases where "Android / Mac has a free standard, while iPhone / Windows only has paid software," then pick the hardest one you happen to be able to build.
How to get users: follow its Chinese open-source distribution chain. Publish a few searchable articles on Cnblogs and CSDN as seeds, open a QQ group, submit to the HelloGitHub monthly, wait for software-sharing blogs and Lao Ai Po Jie to repost it, and pursue GitHubDaily-style accounts. Each stop brings only dozens of stars, but together they form a long tail. It has never worked the English-speaking community; you could try r/sideloaded, r/iphone, and Hacker News, but there's no existing evidence that those audiences would pick it up.
Deadline: if Apple or Microsoft someday builds iPhone mirroring into Windows officially (for example, "Phone Link" adding screen mirroring), demand for tools like this would drop sharply. Until then the window stays open, but there's no firm date.
Ways we could be wrong: (1) a new open-source Windows project that handles only AirPlay passes 1000 stars within three months, which would mean "USB is the barrier" doesn't hold and the barrier was really just naming and distribution; (2) iPhoneMirror stops updating or is broken by an iOS update for three months or more, while a successor grows faster than it did, which would make "do what it hasn't done well" more valuable than we assumed; (3) an English-community post brings in several hundred stars in a single day, which would mean the English market is a big gap that was overlooked rather than a scattering of interest.

Why RayrenSX/iPhoneMirror worked
Channel: GitHub · repo created 2026-07-11 · as of 2026-11-06, 1,721 stars / 131 forks · C# / C++ · GPL-3.0 · author RayrenSX (GitHub account registered 2022 years ago, this is their only notable repo, Chinese developer, has a QQ group)
Bottom line
It fills the "scrcpy gap" in the iPhone world that nobody had filled: Windows + iPhone users who want to mirror their screen to a PC for free, locally, with low latency (ideally with mouse control and direct feed into OBS). Apple's iPhone Mirroring only works on Mac. What exists on Windows is either paid (AirServer, Reflector, iSi screen-mirroring memberships, ApowerMirror), wireless AirPlay only (the UxPlay family), or unmaintained command-line libraries (quicktime_video_hack). iPhoneMirror packages USB wired capture over the private protocol, AirPlay, Bluetooth/CoreDevice reverse control, multi-device support, a borderless window for OBS, and a built-in driver manager into an installer an ordinary person can run on Windows. Its stars didn't come from a single hit. They built up from successive reposts by Chinese open-source recommendation accounts, software blogs and forums starting in September.
1. Data: how it grew
| Timeline | star | What happened | Source |
|---|---|---|---|
| 07-11 | 0 | Repo created; 0.3.0 preview releases published the same day | GitHub releases |

| 09-27/28 | +87 | Included in HelloGitHub Monthly issue 126, with Zendot introductions in Chinese and English | hellogithub.com/periodical/volume/126;zendot.org |
| 10-02 ~ 10-07 | +15~25/day | CSDN article, Pediy 52pojie original-section reposts (1472 views, 19 replies, with Baidu netdisk link), X/Zhihu long post "iPhoneMirror / rPlayHub: which is closer to an iOS scrcpy?" (@chuanliang, 10-05), and nihendiao.com | Various pages |
| 10-09 | 1,107(+57) | First observed source in our database | github repo_day |
| 10-16 | 1,305(+35) | GitHubDaily (major Chinese open-source recommendation account) recommended it on X | x.com/GitHub_Daily/status/2110883436017897900 |
| 10-22 | Recommended by @denziideng on X; reposted by Jianke Wang go176 | Page | |
| 10-28 ~ 11-06 | 1,568 → 1,714 | Steady +15~24 per day, +117 over the last 7 days; 11-05 reached #7 on the GitHub C# daily chart and #12 on the monthly chart (+694 during the monthly window) | GitHub repo_day / trending data |
Key points:
- No single decisive spike. The highest single day was only 115 (09-07), and each recommendation channel brought dozens of stars. The long tail stabilized at 15~25 per day.
- The direct trigger for the 09-07 jump is unidentified: it may have been reposted by a channel after v1.8.3 / reverse control matured, or it may have entered the GitHub C# trending chart as the repo neared 60 days old (trendshift records its best as GitHub Trending #3 and Trendshift C# daily #3). Unverified.
- Downloads say more than stars: all release assets have accumulated about 83k downloads (including in-app auto-update downloads, so not equal to unique users), a star-to-download ratio of about 1:50. This is a project used as a tool, not one bookmarked.
- Real usage signals: 80 issues, nearly all specific model + iOS version compatibility problems (iPhone 17 Pro Max blue screen, iOS 27 handshake timeout, iPad black screen, Sogou input method control issues), titles bilingual in Chinese and English. 7.6% fork-to-star ratio, with PRs proposed (Japanese localization, fullscreen fix). The community has independently ported it to Linux (Furruka) and HarmonyOS PC (zhangziqizZ, Bilibili @Fantasy_zzq). QtScrcpy author barry-ran (32.7k stars) also forked it.
- Anomaly: GitHub's stargazers API returns 0 records for this repo (REST 404, GraphQL totalCount=0, while stargazerCount=1721), so individual star accounts cannot be checked. Cause unknown (possibly GitHub-side privacy or risk handling). However, the trendshift daily curve is smooth, matches external recommendation dates, and the issues and downloads are real, so star fraud seems unlikely.
2. Competitors: who else does the same thing
| Product | Form | Launched | Scale | How iPhoneMirror differs |
|---|---|---|---|---|
| Apple iPhone Mirroring | Big-company features | 2024(macOS 15) | All Mac users | Mac only; Windows users can't use it, which is exactly the demand it addresses |
| Microsoft Phone Link (connect iPhone) | Big-company features | 2023 | Built into Windows | Only notifications, texts, and calls; no screen mirroring |
| iSi screen mirroring (i4.cn) | Commercial Windows software | Years | Large installed base in China | Supports multi-device mirroring, but core features are behind memberships or ads, and it requires the iSi ecosystem; iPhoneMirror even has a built-in "iSi compatibility mode" |
| AirServer / Reflector 4 / LonelyScreen / ApowerMirror / AirDroid Cast / Mulian | Commercial Windows software | 2010s | Mature paid products | Mostly wireless AirPlay only, paid or requiring sign-up, with reverse control behind a subscription; iPhoneMirror is free, local, and combines USB + AirPlay |
| UxPlay (FDH2 3.3k stars, antimof 2.2k stars) / uxplay-windows (849 stars, 2024-04) | Open source | 2020~2024 | Thousands of stars | AirPlay receiver only, command line or simple tray app, no USB, no reverse control, no multi-device UI |
| quicktime_video_hack(danielpaulus,638 star,2019) | Open-source library | 2019 | Small | The first Go library to publicly document the USB private screen capture protocol; a developer tool, not a finished product |
| xenos1337/AirPlayServer | Open source | 2025-11 | 218 star | Windows AirPlay receiver, no USB or reverse control |
| gbulog/pcairplay | Open source | 2026-07 | 121 star | AirPlay + AssistiveTouch reverse control; appeared around the same time but didn't take off |
| rPlayHub(rPlayAI) | Open source | 2026-08 | 73 star | Builds an "iOS scrcpy" on the CoreDevice developer channel, combining viewing and control; but targets macOS/Linux and misses the largest Windows demand |
| MSEndpointMgr/1PhoneMirror, burkeholland/mirror-me, various small AirMirror libraries | Open source | 2026 | Single to tens of stars | All cover only the AirPlay wireless layer |
Conclusion: On Windows, it is the only free, open-source option combining USB wired + wireless + reverse control + multi-device in one installer. Open-source peers reach only the AirPlay layer; commercial peers charge money.
3. Growth levers: where users come from
- Self-promotion seeding (verified): two Cnblogs SEO-titled posts ("ios投屏windows iphone投屏windows", keyword-stuffed), QQ group 1050045279, bilingual Chinese/English README plus Traditional Chinese and Japanese installers.
- Chinese open-source recommendation accounts / newsletters (verified): HelloGitHub monthly issue 126 (+87 on 09-28), GitHubDaily post (10-16), Threads "Daily Trending Projects", Zendot, the kaiyuanbang open-source chart, HelloGitHub badge.
- Software blogs and cloud drive distribution (verified): Xiaoyi, "Xia1 Good Software", Jam's Blog, Diao Ruanjian, Jianke Wang, Huashu Blog, Zhongchuang (online-earning projects forum, reposted as a "practical project"), 52pojie. Nearly all include Quark/Baidu netdisk downloads. This traffic mostly never reaches GitHub, which is why downloads far exceed stars.
- X / Zhihu long posts (verified): @chuanliang's long post comparing iPhoneMirror and rPlayHub ran on both X Article and Zhihu; @denziideng recommended it.
- Scattered overseas reposts (partly verified): YouTube overview video by "Alex Hitt" (281 views), a Vietnamese Facebook open-source sharing page, an Instagram reel (@globalaiforce, "Apple never wanted Windows users to have full iPhone screen mirroring…"). Volumes are small.
- In-app auto-update (verified): checks GitHub Releases on launch with one-click update, keeping existing users on the latest version and sending them back to GitHub repeatedly.
- Not found: paid promotion, TikTok (no iPhoneMirror videos in TikHub search), hot Reddit / HN threads, or press coverage.
IV. Why it took off
- The demand is old, clear, and not met by any free option: Windows + iPhone is the most common combo in China; people need to screen-mirror to record phone tutorials, stream mobile games, demo apps, and test on multiple devices. Reddit / V2EX posts asking "how do I mirror iPhone to Windows" have run for years, and the answer is always paid software or a makeshift AirPlay setup.
- Wired USB is the key barrier: open-source AirPlay implementations for wireless are plentiful, but USB goes through Apple's private Screen Capture protocol, needs a libusb driver, and has to coexist with the Apple Mobile Device driver. The engineering difficulty is high, so almost nobody has shipped a finished tool in this space. It splits driver install/repair/uninstall into a separate driver manager, removing the step that drives most people away from these tools.
- The "scrcpy for iPhone" mindshare slot: the Chinese community naturally benchmarks it against scrcpy (the de facto Android standard, 154k stars), and press headlines read "who comes closest to an iOS scrcpy." Bluetooth HID + AssistiveTouch / CoreDevice control lets it actually control the phone, and that is the selling point in blog headlines since September ("How do I wirelessly control an iPhone from Windows?").
- Detail polish that makes recommenders want to write about it: corner radius / Dynamic Island outlines matched per model, a standalone window with no UI for OBS to capture directly, a 120-fps cap, and raw-frame screenshots. The GitHubDaily tweet said it plainly: "The most practical part is that the standalone window has no extra UI, so OBS can capture just that window."
- Frequent releases + Chinese authors + Chinese community: 45 versions in two months, fast issue responses, README and issue templates in both Chinese and English, and QQ-group support. It serves Chinese users.
5. Differentiation, and whether it's why it took off
The differentiation is integrating USB private-protocol capture, AirPlay, control, multi-device support, OBS output, and driver management into one free, open-source, install-and-go Windows package. Commercial tools charge or require login, and open-source alternatives only do AirPlay or are just libraries. That's why it took off: the core line in every recommendation is "on Windows, free and open source, plug in and mirror, and you can control it too." The growth channels (recommender accounts, software blogs) are nothing special. The product gap is what makes every channel willing to pass it along.
6. Visibility and copycats
- Visibility: it's spreading in small circles. Chinese open-source recommenders (HelloGitHub, GitHubDaily) and software-sharing blog circles have already covered it. English communities, Reddit, HN, and tech media have barely written about it. There is no revenue issue (GPL, free).
- Copycats have appeared: iphonemirror.cn uses the same name as a domain for a "Pro" landing page claiming v1.8.3, "7-day trial, full version unlocks," one license for Win/Mac, and a set of likely fabricated user testimonials ("Bilibili teaching blogger Teacher Lin", "Douyin game streamer Xia Xiaoman"), with downloads via Quark cloud drive. It's a classic move: wrapping a GPL open-source project under a famous name and selling licenses. Separately, a batch of AirPlay-only Windows libraries (AirMirror, mirror-me, 1PhoneMirror, etc.) appeared in 2026, and none of them took off.
VII. What to take away
- Look for the slot where Android has an open-source de facto standard and iOS doesn't (scrcpy ↔ iPhone). The Windows side is especially empty.
- Turn the hard layer (private USB protocol + drivers) into a moat others can't copy easily, and fold in the easy layer (AirPlay) so users don't need "two programs."
- Productize the steps that drive users away: a standalone driver manager, an installer with a bundled runtime, and built-in auto-updates.
- The distribution chain for Chinese open-source projects: self-spread seeds on cnblogs / CSDN → inclusion in HelloGitHub / GitHubDaily → secondary spread through software blogs and cloud drives → forums. Each step yields dozens of stars, but downloads run dozens of times the star count.
- Looking at the commercial angle: iphonemirror.cn is already testing "free open source → repackaged paid version," which shows people will pay for this need. The GPL license and the non-commercial license of iUsbBridge, which the reverse control depends on, would constrain any commercial version.
8. Still uncertain
- The direct source of the single-day +115 jump at 09-07 was not found (possibly the GitHub C# trending chart or a single repost).
- The stargazers endpoint is not readable, so star-account quality can't be verified.
- It's unclear how many of the 83k downloads are repeat auto-update pulls versus unique users. Cloud-drive downloads can't be counted.
- Apple's private protocol may break with iOS updates (issues already report handshake timeouts and AirPlay discovery failures on iOS 27), so the project's sustainability depends on one author (188/216 commits, all from the author).
- Who is behind iphonemirror.cn, and whether they are actually collecting money, has not been verified.
