Yaak, Capgo, Atomic Bot, React Bits Pro: four payment-verified OSS monetization models (2026)

A clean list of four solo maintainers who each crossed $1,000 a month of personal income in the past quarter is still more than the public record can prove. What it can prove is different, and more useful: four independent open-source products now show payment-provider-verified revenue at or above $1,000 a month, each on a different model.

The snapshots below were checked on August 27, 2026. Yaak and Capgo report Stripe-verified monthly recurring revenue well above the line. Atomic Bot does too, and its TrustMRR profile lists a February 2026 founding date. React Bits Pro reports only $829 MRR, but Polar-verified last-30-day revenue of about $52,130. None of these pages is a payroll statement. They are product revenue ledgers connected to Stripe or Polar.

Two of the four products started charging years or months before this quarter. Treat the figures as current run-rates and model evidence, not as four brand-new personal milestones.

1. Yaak: commercial license on prebuilt binaries

What it is: Yaak is a local-first desktop API client for REST, GraphQL, WebSockets, SSE, and gRPC. The mountain-loop/yaak repository is MIT-licensed and shows 19.1k GitHub stars. 1

Public money figure: TrustMRR’s Mountain Loop Labs profile reports $5,282 MRR, 450 active subscriptions, $7,210 in last-30-day revenue, and $83,453 all-time, verified through a Stripe API key and last synced August 27, 2026. 2 3

That is recurring product revenue, not a sponsor total and not a verified personal paycheck. Greg Schier’s December 31, 2025 year-in-review said commercial-license MRR had moved from $160 a year earlier to $1,900, with total revenue past $25,000. 4 The August 2026 TrustMRR snapshot is higher still. The record supports a climb through $1,000 MRR during 2025; it does not stamp a single crossing date inside the past 30 days.

Model: dual path / commercial binary license. Source stays MIT. The pricing page requires a paid license only for commercial use of the prebuilt binaries: Individual $79/year, Business $149/user/year, with a $349 one-time option on the individual product. Licenses are billed annually. 5

Greg’s December 3, 2024 pricing post framed the rule as: if Yaak helps you earn money, Yaak earns money. Personal use stays free. Cloud sync and freemium were both rejected. 6

The trigger: Product launch is dated January 2024; the commercial-use license landed December 3, 2024. 6 7 On October 20, 2025, an AWS outage took Postman offline. Greg reported roughly 20k new downloads and a 6x jump in daily active users after posting on X and Hacker News. 4 Offline reliability became the pitch without a hosted upsell.

If you maintain a project like Yaak, would this work for you?

It fits a desktop or CLI tool people already run at work, where building from source is possible but inconvenient, and where employers will buy a license for compliance and support. The payer is the company that needs the signed binary.

The model is weak if users never touch a prebuilt release, commercial use is rare, or a freemium competitor already owns the team workflow. Yaak’s own survey still flags the license as a switching cost when someone tries to recruit coworkers. 8

2. Capgo: open-source plugin, paid update cloud

What it is: Capgo is live-update infrastructure for Capacitor apps. The open-source core is Cap-go/capacitor-updater (833 stars, MPL-2.0). Teams can use the plugin; Capgo Cloud sells delivery, channels, rollback, and related operations. 9

Public money figure: TrustMRR reports $28,659 MRR, 1,027 active subscriptions, about $37,500 in last-30-day revenue, and $504,362 all-time, Stripe-verified, last synced August 27, 2026. Founder listing: Martin Donadieu; founded November 2021; team size 2–5; bootstrapped. 10 11

This is the strongest current run-rate in the set. It is also the oldest monetization clock. The figure is a mature hosted-business snapshot, not evidence that Capgo first crossed $1,000 in the past quarter.

Model: Hosted Version on the maintainer’s own open-source plugin. Pricing is usage-shaped, not seat-shaped: Solo $12–14/mo, Maker $33–39/mo, Team $83–99/mo, Enterprise $208+/mo, plus pay-as-you-go MAU, bandwidth, storage, and build credits. 12

The trigger: Martin’s origin post (published March 1, 2022; still updated in 2026) says he left Naas in July 2021, rebuilt Captime, needed a production fix without a store release, and found Ionic Appflow too expensive for a side app making about $400/month. App Center had dropped Cordova/Capacitor support. He open-sourced a zip-based update path, saw demand for a managed service, and built Capgo as the maker-priced alternative. 13

The scarce resource is not the plugin file. It is OTA delivery, bandwidth, channels, and the path that keeps store review out of every JavaScript fix.

If you maintain a project like Capgo, would this work for you?

Yes when the open-source piece is a client or SDK and the hard part is recurring operations: push, host, meter, roll back, comply. Mobile live updates are an extreme version of that pattern.

It fails when users can run the full stack cheaply, or when you only resell someone else’s project. Capgo’s plugin repo is the code boundary; the cloud is the paid layer on top.

3. Atomic Bot: local OSS agent app, paid cloud runtime

What it is: Atomic Bot is a multi-platform app for running agent stacks (including OpenClaw and Hermes) locally or in the cloud. The site states the app is fully open source and points at the AtomicBot-ai GitHub org. AtomicBot-ai/atomic-agent is MIT-licensed at 2.4k stars; other org repos package related agent runtimes. 14 15

Public money figure: TrustMRR reports $1,664 MRR, 63 active subscriptions, about $1,490–$1,559 last-30-day revenue, and $26,833 all-time, Stripe-verified, last synced August 27, 2026. Founded February 9, 2026; founder listed as Konstantin. 16 17

Founding date puts monetization inside the past-12-months window. MRR clears $1,000 on a small subscriber base. Last-30-day revenue growth on the snapshot is negative; the run-rate is real and still thin.

Model: Hosted Version. Local use is free; cloud plans sell managed compute and AI credits: Base $19/mo, Pro $39/mo, Max $79/mo. 14

The trigger: The offer is “do not set up keys and servers yourself.” Atomic Bot is not a sponsorship page for upstream OpenClaw. It packages open agent stacks and charges for always-on cloud. Revenue tracks managed infrastructure demand, not goodwill toward a library maintainer.

If you maintain a project like Atomic Bot, would this work for you?

It works when setup cost and always-on compute are the pain, and when you ship your own open-source app rather than only a thin host for someone else’s repo. Sixty-three subscribers at these prices clear $1k MRR; they can also reverse quickly if churn rises.

It is a poor copy if you lack an OSS boundary of your own, or if buyers only want the upstream project. Keep the free local path honest so the paid tier is convenience and capacity, not a hostage feature.

4. React Bits Pro: free component library, paid pack

What it is: React Bits is an open collection of animated React components. DavidHDev/react-bits shows 46.3k stars and ships under MIT + Commons Clause. The free site positions components as source that lands in your repo. React Bits Pro sells additional components, page blocks, app UI, templates, and agent skills. 18 19

Public money figure: TrustMRR reports $829 MRR (100 active subscriptions) and Polar-verified last-30-day revenue of $52,130, with $253,841 all-time and a February 11, 2026 founded date, last synced August 27, 2026. Listed prices are mostly one-time: Starter $99, Pro $199, Ultimate $299. 20 21

Read the two numbers separately. Subscription MRR alone sits under $1,000. The monthly earnings bar still clears on verified 30-day revenue, dominated by one-time pack sales. The Markdown snapshot’s 2026 monthly timeline starts with a large February total and keeps five-figure months afterward. This is a catalog business, not a sponsor drip.

Model: Pro Plugin / paid asset pack on a free library. Commons Clause on the free repo restricts selling the software itself; the free tier is distribution and top-of-funnel for the paid pack. 18

The trigger: TrustMRR dates the Pro product to February 2026. Stars supply attention; Pro converts teams that want full page blocks and product UI without building the motion catalog from scratch. 19 21

If you maintain a project like React Bits, would this work for you?

It fits UI-kit maintainers who can give away a memorable free set and sell completeness: more components, templates, blocks. One-time pricing can produce months that look like SaaS without SaaS retention.

It fails if the free set already satisfies buyers, stars never turn into purchases, or you need predictable payroll and only measure MRR. Publish both recurring and 30-day revenue when one-time sales dominate, or readers will misread $829 MRR as the whole business.

What these four numbers actually are

Project	Verified public figure (Aug 27, 2026)	Evidence class	Model	Time-window note
Yaak	$5,282 MRR; $7,210 / 30 days	Stripe via TrustMRR	Commercial binary license	License launched Dec 2024; $1k MRR cleared during 2025
Capgo	$28,659 MRR; ~$37.5k / 30 days	Stripe via TrustMRR	Hosted cloud on own OSS plugin	Product monetization since early 2020s
Atomic Bot	$1,664 MRR; ~$1.5k / 30 days	Stripe via TrustMRR	Hosted agent cloud on own OSS apps	Founded Feb 2026
React Bits Pro	$829 MRR; $52,130 / 30 days	Polar via TrustMRR	Pro pack / one-time catalog	Founded Feb 2026; monthly bar is 30-day revenue

For product businesses, separate four fields the way sponsorship pages should:

Received: period revenue (30-day and all-time on these TrustMRR pages).
Committed: MRR when the product is subscription-shaped.
Disbursed: not public here; no founder salary line.
Who gets paid: the Stripe/Polar account holder — still not itemized as maintainer take-home.

If you only publish the largest number, React Bits looks like a $52k MRR SaaS. If you only publish MRR, React Bits looks like it failed the $1k line. Publish the shape of the money.

Model-fit matrix

Project archetype	Models to test first	Why the fit is plausible	What to prove before copying it
Library	Sponsorship, paid support, pro pack / docs	A dependency creates recurring risk; a UI library can also sell completeness as a pack. React Bits shows the pack path with Polar-verified sales.	Separate stars from buyers; if one-time sales dominate, report 30-day revenue beside MRR.
Framework	Dual license, paid support, hosted control plane	Frameworks shape production architecture, so companies pay for binaries, support priority, or hosted operations.	Name the commercial boundary (binary, support SLA, or hosted service) without walling the core behind freemium theater.
CLI / desktop tool	Commercial binary license, pro plugin, hosted companion	Yaak shows employers will pay for signed prebuilds and compliance while source stays open.	Confirm users actually run your prebuild at work; offline or local-first trust can be the pitch.
Web / cloud tool	Hosted version, pro plugin, paid support	Capgo and Atomic Bot charge for delivery, compute, and operational burden the free code does not remove.	Own an open-source boundary; price the recurring job (MAU, bandwidth, uptime, credits), not a donation tier.

The practical threshold is a payer who can explain what next month’s money buys: a commercial binary seat, a live-update pipeline, a managed agent box, or a complete component pack. Verified revenue makes the model legible. It does not turn every ledger into a maintainer salary.
