There's a free open source tool that cuts your AI API bills by up to 95% without touching a single line of your code. And it's called Headroom. If you're building anything on top of GPT or Claude, the API bill is what quietly drains your runway. Every call costs money and most of those calls are repeats.

Headroom sits between your app and the AI model. It caches the answers, strips out the junk you're sending, and routes the cheap requests to cheaper models automatically. You don't rewrite anything. It just sits in the middle and does it for you. Here's how to set it up this week. Step one, grab Headroom from GitHub.

It's free and open source. Step two, point your app at Headroom instead of the model's API. That's one line in your config. Step three, watch the dashboard. It shows you every cached call and exactly how much you just saved. One open source tool, up to 95% off your biggest bill in an afternoon.
