## Where the opening is

*Model estimate*

- The signals do not show a product focused specifically on indie SaaS teams that want a lightweight billing layer instead of a full metering, invoicing, and revenue platform.
  - [getlago/lago](https://github.com/getlago/lago) `github` — 2022-02-28
  - [killbill/killbill](https://github.com/killbill/killbill) `github` — 2012-10-21
  - [meteroid-oss/meteroid](https://github.com/meteroid-oss/meteroid) `github` — 2023-07-13
  - [service-bot/servicebot](https://github.com/service-bot/servicebot) `github` — 2017-04-30
  - [billabear/billabear](https://github.com/billabear/billabear) `github` — 2023-03-09
- Most named players are either broad infrastructure stacks, Stripe wrappers, or API monetization tools; the search does not show a clear indie-first workflow for setup, plan changes, dunning, tax handling, and customer self-serve in one small package.
  - [getlago/lago](https://github.com/getlago/lago) `github` — 2022-02-28
  - [killbill/killbill](https://github.com/killbill/killbill) `github` — 2012-10-21

  - [laravel/cashier-paddle](https://github.com/laravel/cashier-paddle) `github` — 2020-04-27
- The data also does not show a strong existing niche for billing tools that are opinionated around tiny SaaS teams, especially if the product is meant to be simpler than Lago or Kill Bill.
  - [getlago/lago](https://github.com/getlago/lago) `github` — 2022-02-28

## How big the market might be

*Model estimate*

- This search found 12 named open-source projects, with 6 active, 2 dead, and 4 slow.
- There were 14 first-hand complaints, 2 unsolved questions, and 12 stated wants across the collected signals.
- The largest usage signal was react-native-purchases at 2,999,080 downloads last month, followed by @revenuecat/purchases-capacitor at 732,700 downloads last month.
  - [npm: react-native-purchases](https://www.npmjs.com/package/react-native-purchases) `registries` — 2026-07-31
  - [npm: @revenuecat/purchases-capacitor](https://www.npmjs.com/package/@revenuecat/purchases-capacitor) `registries` — 2026-07-31
- Matching community threads appeared in community.home-assistant.io, community.n8n.io, community.openai.com, and meta.discourse.org.
- On GitHub, the live competitors are not tiny hobby repos: Lago has 10,281 stars, Kill Bill has 5,646 stars, Meteroid has 1,163 stars, and Laravel Cashier Stripe has 2,540 stars.
  - [getlago/lago](https://github.com/getlago/lago) `github` — 2022-02-28
  - [killbill/killbill](https://github.com/killbill/killbill) `github` — 2012-10-21
  - [laravel/cashier-stripe](https://github.com/laravel/cashier-stripe) `github` — 2014-03-04
  - [meteroid-oss/meteroid](https://github.com/meteroid-oss/meteroid) `github` — 2023-07-13

## What could go wrong

*Model estimate*

- Competition is heavy and already well funded by usage: several live projects have thousands of stars and some packages have millions of monthly downloads.
  - [getlago/lago](https://github.com/getlago/lago) `github` — 2022-02-28
  - [npm: react-native-purchases](https://www.npmjs.com/package/react-native-purchases) `registries` — 2026-07-31
  - [killbill/killbill](https://github.com/killbill/killbill) `github` — 2012-10-21
  - [npm: @revenuecat/purchases-capacitor](https://www.npmjs.com/package/@revenuecat/purchases-capacitor) `registries` — 2026-07-31
  - [laravel/cashier-stripe](https://github.com/laravel/cashier-stripe) `github` — 2014-03-04
  - [meteroid-oss/meteroid](https://github.com/meteroid-oss/meteroid) `github` — 2023-07-13
- A new product may get squeezed unless it is much simpler, much faster to adopt, or clearly built for a narrower niche than the existing billing stacks.
  - [getlago/lago](https://github.com/getlago/lago) `github` — 2022-02-28
  - [killbill/killbill](https://github.com/killbill/killbill) `github` — 2012-10-21

  - [stripe-samples/checkout-single-subscription](https://github.com/stripe-samples/checkout-single-subscription) `github` — 2019-08-27
- Billing is a trust-heavy category, so small bugs can become public complaints fast; the signals include reports of incorrect subscription state and failed renewals.
  - [User can't repurchase a subscription product after canceling](https://meta.discourse.org/t/user-cant-repurchase-a-subscription-product-after-canceling/199602/11) `discourse` — 2021-08-24

- The idea can drift into a crowded general-purpose market if it tries to cover metering, invoicing, payments, entitlements, tax, and analytics all at once.

## What to do this week

*Model estimate*

- Narrow the product to one painful wedge: subscription setup plus plan changes plus customer self-serve for indie SaaS, not a full billing platform.

  - [service-bot/servicebot](https://github.com/service-bot/servicebot) `github` — 2017-04-30
- Build around the kinds of problems people actually asked about: usage tracking under one subscription, annual billing, and clean subscription state after payment events.

- Target founders using Stripe who want less plumbing than Cashier or Lago, and position it as the smallest thing that gets recurring revenue working.
