Running 19 iOS simulators on a 16 GB Mac: simslim turns off 175 unused background processes

What it is A macOS command-line tool. One command turns off about 175 background processes the iOS simulator doesn't need. Memory per simulator drops from 4 GB to 0.9 GB, so one Mac can run several times as many simulators.

Why it took off Over the past 2026 year, agents have been writing code in parallel, and each agent needs a simulator. On a 16 GB laptop, running 5 of them locks it up. It spread with one chart, "4 GB vs 0.9 GB, 5 simulators vs 19," from Reddit into comments on iOS Dev Weekly, RedMonk, and Theo's posts. Agent tools like stim and Simlock then embedded it as a dependency.

CHow you can ride it Don't build another simulator slimmer. iOS and Android versions both already exist. Copy its method for finding opportunities: look for the other resource that agents exhaust first in parallel work, build a small tool that works in one command, can be reverted, and can be imported by other tools, then launch it with a before-and-after chart.

Grade C: "simulator slimming" is now effectively claimed by this project. The Android version, avdslim, came only 8 weeks later and got just 333 stars, so copying it or porting it to another platform isn't worth it. What's worth learning is its way of finding problems and its launch rhythm, not the project itself. Chatter in small circles

Data (updated daily) · Repo created 2026-07-20 · 3,519 stars · 7 days +120: GitHub · stars

An iOS simulator eats 4 GB of memory right after boot, because it runs Siri, Spotlight, wallpaper posters, and other things nobody looks at. simslim turns them off and brings one instance down to 0.9 GB. Created in Jul 2026 20, it had 6 3,499 stars by Nov. The problem has existed for a long time. It blew up because AI agents started running a dozen simulators at once for one person. Below: how it got its stars, who's already following it, and where you can jump in.

One chart: 4.0 GB vs 0.9 GB

On Jul 24 2026, MobAI, which makes mobile agent tools, published a post on its blog titled "I Got 19 iOS Simulators Running on a 16 GB MacBook." On the left of the header image is a normal simulator at 4.0 GB; on the right are 19 "slimmed-down" ones, each 0.9 GB.

The first paragraph lays out the math: a freshly booted simulator has 258 processes and about 4 GB of memory, and a 16 GB Mac starts choking at around 5 of them. Inside are roughly 180 background services: Siri, Spotlight indexing, photo analysis, news widgets, iCloud sync, Screen Time, ad services. In short, "basically a full iPhone, just without the hardware." The author's favorite number: widgets and wallpaper posters alone take about 675 MB while idle, "more than some full Linux VMs. For a lock screen nobody ever looks at."

The fix is one command, simslim on <udid>. It writes launchctl disable into the simulator's own launchd database, then restarts the simulator. After that:

	Original	After slimming
Process count	258	70
RAM	4.0 GB	0.9 GB
Simulators one 16 GB Mac can run at once	About 5	19

Source: MobAI blog, 2026-07-24.

What it actually does

simslim is a macOS command-line tool written in Go, with a small SwiftUI interface on the side, MIT-licensed, installable with brew install. It's safe to use because of these design choices:

Only turns off processes on an allowlist: about 175 daemons, grouped into 16 feature categories, each with a memory estimate. A few processes that would hang the simulator if disabled are hard-excluded and guarded by dedicated tests. Anything not on the list is left alone.
States what breaks upfront: the blog has a section titled "Honestly, some things will break." After turning it off, Spotlight search stops working, push needs apsd, StoreKit testing needs storekitd, and universal links need swcd. Keep whatever you need: --except search keeps a whole category, and --keep com.apple.apsd keeps a single service.
Preflight checks and rollback: simslim doctor <udid> --requires push,storekit returns a non-zero exit code when something needed is missing, so it can be the first step in CI. simslim off restores everything to the original state, and it "never touches your Mac, only the simulator you specify."
Still actively updated: as of v0.13.0, it supports tvOS, watchOS, and visionOS, and adds watch (new simulators slim down automatically), offline slimming before boot, disk cleanup, and timeout options for slow CI.

The author ends the blog with why they built it: "Agents write apps, so agents need to run them too, and iOS apps run in simulators. One agent, one simulator. How much parallel work one machine can do depends on how many simulators it can hold."

Why it blew up in 2026

Simulators eating memory isn't a new problem. Nobody built a dedicated tool for it because people used to run one or two at a time. In 2026, Claude Code and Codex started running several sessions in parallel, and each session needs a simulator. RedMonk's Sep 15 report "Agents with iPhones: Why the Simulator Market is Blowing Up" says agents "need a dozen, each for ninety seconds," and cites simslim's "180 background services" as evidence.

In Oct 30, developer An Tran recommended simslim on LinkedIn (59 reactions), saying Codex and Claude opened a pile of simulators and locked up his laptop. Agents made the old problem many times worse at once, and simslim arrived right then.

Where the stars came from

It never hit the Hacker News front page, and no big account posted about it. The path to 3,499 stars went roughly like this:

Posted to Reddit the day the repo was created (7-20): a post in r/iOSProgramming, "I made a small tool to reduce iOS Simulator memory usage," with 20 upvotes and 11 comments. The same day, a post in r/ClaudeAI emphasized it was "written with Claude Code."
Blog post 4 days later (7-24): the 4.0 vs 0.9 chart above. 7-26 it was also shared in a MobileNativeFoundation discussion, posted by the repo's top contributor.
Demo post a month later (8-29): r/ClaudeAI, "Claude Code drives 12 iOS simulators simultaneously on my M1 Pro MacBook with 16 GB Ram," with 167 upvotes and 34 comments. The post matches the demo video in the README, so it was most likely posted by the official account (inference).
iOS community newsletter (9-04): iOS Dev Weekly issue 766 put "Boosting simulator performance with SimSlim" in its headline.
Analyst report (9-15): the RedMonk report mentioned above.
A top V's post had replies recommending it (10-25): Theo (t3.gg) posted that he runs iOS simulators on a Mac mini from an Ubuntu box via T3 Code, "the best iOS dev experience I've had," 190k views. A reply from @incanescent in the comments: "Anyone relying more on simulators these days should look at Sim Slim… I've been doing a lot of interaction testing and was already starting to struggle." That reply got 4.9k views. simslim gained 224 stars that day and 142 the next (Trendshift, ranked #2 and #4 on the Go chart).

Working backward from Trendshift's data, the first 7 weeks after the repo was created brought in about 1,650 stars, and from 9-07 to 11-06 it added 1,851 more. Separately, 9-21 gained 212 stars that day. I couldn't find a specific source for it; it may have been GitHub Trending (inferred).

There's also a steady long tail: other tools embedding it as a dependency. stim, an RN/Expo tool, built SimSlim into a machine-level toggle. Callstack's Simlock syncs its config to simslim's categories; an issue there reads "re-sync slim-labels.ts with simslim's new mdm category." Once others depend on it, everyone using those tools sees the link.

Who's following

Name	What it is	Timeline	Result
Pitlane	A paid macOS app where killing processes is only one feature	2026-08-31	Only 4 votes on Product Hunt; the marketing copy is nearly identical to simslim's July blog post
SwiftSimSlim	A pure-Swift rewrite of simslim's approach	2026-09	The author sent improvements back upstream to simslim (issue #50), and they were merged into the main repo
avdslim	An Android emulator version whose README's first line reads "Inspired by simslim"	2026-09-16	Memory cut from 8.5 GB to 2.5 GB; 7 stars in 333 weeks, +7 over the last 9 days (GitHub, 11-06)
simfleet	A unified console for running parallel simulators	2026-09-25	127 stars
A batch of verbatim-copied forks and download pages	Riding the traffic	8 to October	Shows how hot it got that people were cloning it in bulk

Others had the same idea earlier, but never built it as a standalone tool: a WebKit PR in August disabled a batch of daemons for its own testing; someone posted on LinkedIn a trick that killed only 3 processes and dropped memory from 2.3 GB to 1.9 GB; AutoMobile and vphone-cli had similar lean profiles. simslim was the first to do the whole thing, do it safely, and open-source it on its own.

The most instructive is avdslim. It takes the same idea to Android, with equally good numbers (saving about 6 GB), launched only 8 weeks after simslim, and ended up at 333 versus 3,499 stars. Porting to another platform still earns some stars, but the first mover takes most of them.

Its weak spots

Depends on undocumented Apple internals: which processes get killed relies on daemon labels Apple has never documented, so they have to be re-curated with every new iOS release. If Apple ships a built-in "lean mode" in Xcode, or changes how launchd works, this tool becomes useless.
Real usage is unclear: 3,507 stars but only 11 watchers (GitHub, 11-06). Many people probably starred it after seeing the comparison chart without actually installing it (inferred).
Backed by a commercial company: MobAI makes a paid mobile agent tool. simslim is open-sourced to drive traffic, and mobai.run's device page states outright "our open-source simslim." Solo open-source projects can't easily replicate this kind of distribution: the blog, demo videos, Reddit, and newsletters.

If it were you

In one line: building on simslim, or porting it to Android, has already been done. What's worth learning is how it found its problem: an agent multiplied an old pain point many times over, and the result was a small, one-command, reversible tool.

Who it's for: developers who understand a platform's internals (simulators, containers, browsers, build systems), who run agents in parallel themselves, and who have been blocked by resource limits.

Who it's not for: anyone who wants to build "iOS simulator slimming" directly. simslim is already the de facto standard, and other tools depend on it. Anyone aiming at an Android version is also late; avdslim came out in September.

How to do it:

Find the resource that runs out first when agents run in parallel. Simulator memory is already covered, but you could look at Xcode's DerivedData and disk usage, per-instance memory for Chrome in browser automation, Docker sandbox cold starts, or port and account isolation. Pick one you can explain with a clear before-and-after number.
Polish it the way simslim does: one command, fully reversible, touches only an allowlist, documents what might break upfront, and includes preflight checks. Developers need to feel safe trying it, and only then will other tools dare to depend on you.
Make it an importable library, not just an app. Half of simslim's long-tail traffic came from dependent tools like stim and Simlock.

How to get users: post on the relevant subreddit the day you launch, stating clearly "here's what was blocking me." Within a week, publish a blog post with a number in the title and a before-and-after chart. Within a month, release a demo video of "an agent driving N machines at once" and post it to agent communities like r/ClaudeAI. Then pitch the niche newsletters and open issues on agent tools suggesting "can plug into xx." A single recommendation under a top V's post may do more than ten of your own posts.

Timing: the wave of parallel agent development is still climbing, and resource problems keep surfacing one by one. Whichever niche first gets a before-and-after chart published is largely claimed; simslim and avdslim were only 8 weeks apart.

Signs you picked the wrong problem: the platform vendor fixes your resource problem itself in the next major release, such as Apple shipping built-in simulator slimming in Xcode; or stars stay in the double digits two weeks after you publish your comparison chart. The first means the problem shouldn't be solved by a third party; the second means the pain isn't widespread enough.

MobAI-App/simslim: why it works

In one line: a macOS command-line tool written in Go (with a SwiftUI shell) that uses launchctl disable to turn off the roughly 175 background daemons that iOS/tvOS/watchOS/visionOS simulators don't need. Memory per simulator drops from 4.0 GB to 0.9 GB, so a 16 GB Mac can run 12 to 19 simulators at once, up from about 5. It was open-sourced by MobAI (a mobile automation tool for coding agents, with a paid tier) to drive traffic.

Research date 2026-11-06. Data comes from our github database (repo_day starting 2026-10-09), Trendshift, GitHub, Reddit and X search snapshots, iOS Dev Weekly, and RedMonk.

1. Data

Created 2026-07-20; as of 11-06 it had 3,499 stars and 154 forks, and gained 213 over the last 7 days (github database, repo_profile). The GitHub API showed 3,507 stars that day, but only 11 watchers.
Trendshift daily data (https://trendshift.io/repositories/88525): 1,851 stars gained from 9-07 to 11-06. Working backward, the first 7 weeks after creation (7-20 to 9-06) brought in about 1,650 stars, meaning half the stars arrived in the first 7 weeks.
- 9-18: +45 (Go Trendshift chart #23); 9-21: +212 (Go chart #7);
- Mid-to-late October saw 5 to 15 per day, mostly long tail;
- 10-25: +224 (Go chart #2); 10-26: +142 (#4); 10-30: +83; after that, 7 to 25 per day.
The largest single-day gain in our database was 10-31 on 76 (the database is authoritative here; Trendshift recorded +29 that day, so the two sources count differently). The data card's "10-18 to 10-28 gained 513" comes mainly from 10-25 and 10-26.
The star-history endpoint (stargazers with timestamps) got rejected this time (403/404), so the daily data from 7 to August is unverified.

II. Competitors and adjacent tools

Directly doing "slim down the simulator"

Name	Form	Timeline	Scale	How it differs from simslim
Pitlane(Vadim Drobinin,drobinin.com/apps/pitlane)	Paid macOS app, 14-day trial	2026-08-31 posted on LinkedIn; launched on Product Hunt 10-24 with only 4 votes	Very small	Repackaged as "an Xcode alternative for indie developers"; killing daemons is just one feature. Closed source, paid. The marketing copy ("wallpaper posters", "600%") is nearly identical to simslim's July blog post, and it shipped 6 weeks after simslim.
SwiftSimSlim(Anywhere-Music-Player)	Open-source SwiftUI app	2026-09	Small	A pure-Swift rewrite based on simslim. The author offered in simslim issue #50 to contribute the code back, and simslim then merged the performance improvements from it in PR #51.
Artem Novichkov's LinkedIn post	A trick	2026-09-03	—	Only disabling 3 daemons (PosterBoard, chronod, liveactivitiesd) drops memory from 2.3 GB to 1.9 GB, far less effective than simslim.
WebKit PR #72356 "reduce the number of daemons running on simulators"	Internal test scripts at big companies	Merged 2026-08-25	—	Only for WebKit's own tests; never built into a general tool.
AutoMobile's lean profile, vphone-cli's trimmed profile, a CircleCI help article (2026-05)	A sub-feature or a doc page inside other tools	2026 years	—	Same idea, but only as a side feature with no standalone product.
Old approaches: nihongo-app blog "Running 1 simulators in parallel on an M14", bluepill (3.2k stars, 2017)	Blogs / parallel-testing tools	Several years ago	—	Relies on parallel scheduling or system settings tweaks; doesn't touch the daemons inside the simulator.

The adjacent "agents controlling simulators" niche (simslim is the foundation for these): mobile-next/mobile-mcp (10.3k stars), callstack/agent-device (5.3k), EvanBacon/serve-sim (2.9k), Callstack's Simlock, appandflow/stim, T3 Code's Device Hub (9-10 launch), expo-device-hub; cloud options Revyl, Limrun (both YC), Expo EAS Simulators; and Apple's Device Hub in Xcode 27. All of these products have to solve the same problem: simulators eat too much memory. Of these, stim and Simlock already call simslim directly, or sync with its categories (stim PR #4244, issues #4869/#4870; Simlock issues #1192/#1244 mention "re-sync slim-labels.ts with simslim's new mdm category").

Bottom line: in the "standalone, open-source, categorized, reversible simulator-slimming tool" slot, simslim was first and is the only one at scale. Everything after it is either copycat or embedding it.

III. Growth levers (where users come from)

The founder posted on Reddit the day the repo was created (confirmed): 2026-07-20, r/iOSProgramming "I made a small tool to reduce iOS Simulator memory usage" (20 upvotes, 11 comments); the same day they posted in r/ClaudeAI (0 points, 12 comments) with a title stressing "written with Claude Code" and "agents can already control simulators, but...".
Official blog with a high-contrast comparison image (confirmed): 7-24 MobAI blog "I Got 19 iOS Simulators Running on a 16 GB MacBook". The title is all numbers, and it highlights shareable details like "wallpaper posters alone take 675 MB". 7-26 also reposted it in MobileNativeFoundation discussions #233 (poster Interlap01, also the repo's top contributor).
Riding agent hype with a demo video (post confirmed to exist; likely official): 8-29 r/ClaudeAI "Claude Code drives 12 iOS simulators simultaneously on my M1 Pro MacBook with 16 GB Ram", 167 upvotes, 34 comments. The demo video in the README shows exactly this: 12 slimmed simulators on an 16 GB M1 Pro, each driven by a Claude Code agent through MobAI, and the content matches.
iOS community's core newsletter (confirmed): iOS Dev Weekly issue 766 (2026-09-04) put "boosting Simulator performance with SimSlim" in its newsletter title. The same day, r/iOSProgramming also had "A small trick to make iOS simulators use less RAM".
Analyst report (confirmed): RedMonk 2026-09-15 "Agents with iPhones: Why the Simulator Market is Blowing Up" lists simslim as a representative standalone tool and uses its "180 background services" to support the argument about capacity.
Recommended in the comments of Theo's viral post (confirmed; timing matches the +224 on 10-25): 2026-10-25 Theo (@theo, t3.gg) posted that he runs iOS simulators on a Mac mini via T3 Code from Ubuntu, 190k views. In the comments, @incanescent recommended simslim ("Absolutely look in to Sim Slim", 4.9k views). That day it hit #2 on the Go chart, and over the next two days it gained 142 and 48.
Other tools embedded it as a dependency and it became infrastructure (confirmed): stim (janicduplessis, RN/Expo community) turned SimSlim into a machine-level switch; Simlock syncs with simslim's categories; FestivalNativeApps PR #839 makes every local launch run simslim first; mobai-ci has sim-slim flags built in. Around the +10-30 on 83 there were LinkedIn posts (An Tran, 59 reactions): "Codex and Claude spin up a pile of simulators and freeze my laptop."
No specific source found for the +9-21 (Go chart #212) on 7. It may have come from simply landing on GitHub Trending.
Not found: Show HN (not in the HN archive; MobAI's own January Show HN has only 1 points), paid ads, original big-account posts on X (simslim doesn't show up in the x-radar corpus).

There are also many verbatim forks (zuxine, mo-mew, plu, sunjinshuai, enumcase, MaTriXy/ios-simslim...) and a GitHub Pages site epidemic-suretybond423.github.io (now 404). This is the common GitHub pattern of copying a popular repo plus a download page, a sign it got hot enough to be mass-copied.

IV. Why it took off

The pain got ten times worse with agents, perfect timing: people used to run one or two simulators at a time. In 2026, Claude Code and Codex can run many sessions in parallel, and each agent needs a simulator (RedMonk's phrasing: agents "want a dozen for ninety seconds each"). A 16 GB laptop choking on 5 simulators is a new, very painful problem (An Tran's LinkedIn post and the r/ClaudeAI post about 12 simulators are both about this).
Memorable numbers spread easily: "4 GB → 0.9 GB", "5 simulators → 19", "wallpaper posters take 675 MB". One image tells the story, and from Reddit to the newsletter to RedMonk, people keep quoting these same figures.
Low barrier, easy to reverse: brew install and one command, simslim on <udid>, does it. off fully restores, and it only changes the simulator, not the Mac itself. It disables only daemons on an allowlist, with a doctor preflight check, --except/--keep flags, and JSON profiles. Developers can try it without worry.
Kept updating, turning a one-off trick into a tool: now at v0.13.0, with support for tvOS/watchOS/visionOS, a GUI, disk cleanup, watch that auto-slims newly booted simulators, offline slimming before launch (PR #65, a community contribution), and timeout flags for slow CI. It also absorbed improvements from SwiftSimSlim. This moved it from a idea to something stim and Simlock can safely depend on.
A commercial company handles distribution: MobAI makes mobile agent tools. Its other open-source library, ios-builder, already has 1.2k stars. The team writes blogs, makes demo videos, posts on Reddit, and publishes YouTube Shorts (LookOnThisGit). They also know how to connect simslim to their own mobai-ci and the paid MobAI version (the mobai.run/devices page explicitly says "simslim, which we open-sourced").

5. Differentiation

Others only disable 3 daemons, or only do it inside internal scripts. simslim covers about 175 daemons, organized into 16 categories, with a memory estimate for each category, reversibility, and preflight checks, across four platforms. It has a full knowledge base on "what can be disabled and what breaks if you do" (docs/category-memory.md, plus hard-exclusion tests for daemons that freeze simulators).
Open source (MIT) + CLI + an importable Go package, so agent toolchains (stim, Simlock, the T3 Code ecosystem) can embed it directly. Pitlane is a closed-source paid app and can't be used as a dependency.
This is why it took off: it was the first to do the whole job thoroughly and safely, right as agents started running simulators in parallel. Being open source let other tools embed it, which made it the de facto standard. Later copycats (Pitlane, SwiftSimSlim, various forks) came out more than 6 weeks after.

VI. How visible it is

It's known in small circles: the iOS dev community (iOS Dev Weekly, r/iOSProgramming) and the agent mobile-dev crowd (RedMonk, comments on Theo's post, the T3 Code / Expo / Callstack ecosystem) all know it, but no big-account original post focused on it, and it never hit the HN front page. It's free and open source, so there's no public revenue.

VII. What others can borrow

Find a place where agents make an old problem 10 times worse (resources, concurrency, isolation), build a small tool that works with one command and can be reversed, and spread it with a striking number (4x, 19 simulators).
The main product is commercial, so split out an independent open-source tool to bring in traffic. Once other people's toolchains embed it, it keeps generating exposure and can funnel users back to the main product (mobai-ci, MobAI Pro).
Launch cadence: Reddit on the day the repo was created, a blog 4 days later, a demo video a month later (agent driving 12 simulators), then the newsletter and analyst report, with the long tail coming from big-account post comments and the tools that depend on it.

8. What's still uncertain

7 through August: daily star counts weren't obtained (the stargazers API was rejected). The first 7 weeks' roughly 1,650 stars were back-calculated from Trendshift. Whether the 8-29 r/ClaudeAI post was made by MobAI itself is unverified. The source of the +9-21 212 is unknown.
Real usage is unclear (only 11 watchers; Homebrew install counts weren't checked).
If Apple's Xcode 27 Device Hub or future simulator runtimes ship a native lean mode, or change the launchd mechanism, this tool could become useless. It also depends on daemon labels with no public documentation, and it has to be maintained again for every iOS version.
