Limitly
Authentication for your API
Hey indie hackers! 👋
I'm building Limitly, a simple way to protect and monetize your public APIs — without building a full auth or rate-limit system from scratch.
If you're building a product that exposes an API (e.g. for your AI app, dev tool, or micro-SaaS), Limitly helps you:
Issue API keys to your users
Set usage limits (daily, monthly, etc.)
Monitor & validate usage in real time
Prevent abuse with rate limits
All via a lightweight SDK (Node.js, Next.js & Python supported)
⚡ It’s fully hosted and takes less than 10 minutes to integrate, just wrap your endpoints with our SDK, and you're good to go.
I've been scratching my own itch after rebuilding this kind of system for a few projects. Now I'm turning it into something others can use out of the box.
Would love feedback from other API builders, what features would you need? What’s missing in your current workflow?

Happy to answer questions or help you get started. Thanks! 🙌
