How open-source projects make money: take over abandoned open-source projects, or build paid vertical versions on an open-source base. The only successful example added a paid tier in its first month of launch
- Status
- Watching (of 6 open-source samples, only WhatCable shows any sign of payment, and its revenue is not public)
- Why this is written up
- Open source can earn stars and installs, but projects that "spread wide first and figure out money later" had not made any money half a year on. Two paths are worth borrowing. First, take over an abandoned old project: Thaw picking up Ice's users is far cheaper than building a new product, and the gaps it leaves are the App Store version, iCloud sync, and enterprise distribution. Second, build a paid vertical edition on an open-source base: Dograh, LiveKit, and Pipecat already own the foundation of voice agents, and the open position is packaging by industry (hospital and restaurant phone reception). Goldfish validated the interaction of "local context + one key" but has never charged.
- Confidence
- Low to medium (the pattern comes from 6 samples, and the one that succeeded has undisclosed revenue). What would disprove it: if Thaw, Dograh, or Emdash adds a paid tier and indie sees 30-day revenue above $1,000. What would upgrade it: WhatCable or a similar project publishing its revenue.

GitHub4 evidence · 6 products with curves
- GitHub (verified by 11-02): thaw-app/Thaw (a GPL fork of Ice, a Mac menu bar manager) 12,473 stars (the report says 12,451), roughly +20 per day; upstream jordanbaird/Ice 29,930 stars, last stable release 2024-10-29.
- GitHub (verified by 11-02): dograh-hq/dograh (open-source Vapi alternative, voice agent platform) 6,005 stars, fork/star ratio 25.6% (median for its cohort is about 11%; users are "taking it to use themselves"). Web (Docker Hub, PH archive 11-01): the two official images were pulled 86,797 and 81,313 times; the cloud version charges a platform fee of 1¢/min, and it isn't in indie, so there is no public evidence of revenue. PH 2026-08-12 583 votes, daily rank #1.
- GitHub (verified by 11-02): generalaction/emdash (open-source desktop app for running multiple coding agents, YC W26) 6,141 stars, gaining 8–10 stars per day since PH. The 2.0 team edition only has a waitlist, and most of the site's "1M downloads" are update checks. SECHAK-AG/capptivo (free open-source screen recorder) 1,112 stars, no commits since 10-13; PH 323 votes, daily rank #2.
- GitHub (verified by 11-02): darrylmorley/whatcable 9,069 stars. Two weeks after launch (05-14) it added Pro (£9.99 one-time purchase). Main development moved into a private repo, the public repo is only a mirror, the Pro plugin is closed-source, and the community hasn't pushed back. 1.3.0 and 1.5.0 added "recover license" and "release device slot" respectively, which suggests a batch of paying users already exists (inferred). See [052].
Other sources (official sites, press releases, web pages) 1 pieces of evidence
- Web (Homebrew analytics, GitHub Sponsors, PH profile 11-01 scrape): Thaw's cask was installed 3,208 times in the last 30 days, and 30,374 times in 365 days; upstream Ice's cask was installed 4,026 times in 30 days. Thaw has 28 current Sponsors and 89 all-time. Completely free: no Pro, no App Store version, no iCloud sync or enterprise distribution. PH: 2026-09-03 131 votes.
Product Hunt2 pieces of evidence
- PH: Goldfish (local AI memory for Mac / Windows that drafts replies in any text box with one keypress) 2026-06-16 946 votes, daily chart #1, 303 comments; still free with no pricing page, is an EF portfolio company, and isn't in indie. The profile's recommendation is a paid one-time-purchase vertical version (only for sales outreach, or only for customer-support replies), priced on day one.
- PH (follow-up tracking of 25 products, §3.7): among the 6 open-source products, WhatCable added a paid tier within two weeks; Thaw, Capptivo, Emdash, and Dograh all spread out first and figured out monetization later, and still haven't collected revenue half a year on; Caveman has 116,663 stars and only just launched a Team tier at $300/month, 10-13, with no revenue visible yet. The pattern: add the paid tier in the first month, or you'll never add it.
Already doing it
Thaw (free), Ice (stopped updating), Dograh (cloud version paid, no revenue evidence), Goldfish (free), Emdash (free, team version waitlist), Capptivo (free, winding down), WhatCable (Pro one-time purchase, see [052]), Caveman (Team tier just launched).
In our product profiles: Dograh, Emdash, WhatCable
The hardest step
GPL forks can't go closed-source and charge more (the trap Thaw fell into); open-source users don't pay by default; taking over a system-level macOS tool means rewriting it after every WWDC.
Who it's for
A team of 1–2 people who can maintain a system-level tool long-term. The play is an open-source core plus a closed-source Pro one-time purchase ($10–20), launched within the first month; or industry bundling on an open-source base, charging from the start.
Should every product builder know this?
Yes. Anyone building open source should know that the paid tier has to ship in the first month.
