TokenBrake is free and source-available — everything unlocked, unlimited agents, forever, for individuals and for companies under 100 people and under $1M revenue. No card, no account, no signup. Download it, point one URL at it, and see what every AI on that machine is costing you — cloud dollars and local watts together — with a hard cap and a runaway breaker in front of the bill.

Everything is unlocked from the moment you install it: unlimited monitored agents, the runaway breaker, per-agent budgets and every cap. No trial clock, nothing held back, no paid tier with the good features in it. Free for individuals, and for any company under 100 people and under $1M revenue — which is almost everyone. Larger companies need a commercial licence: one payment, one company, no renewal. Nothing about licensing ever stops your API traffic — the only things that ever stop a call are the budget cap and the breaker, which are the features you came for. TokenBrake will never hold your pipeline hostage over a key.
TokenBrake is made by Northjule — that's the name you'll see on your receipt. The source is public on GitHub, so you can read every line before you run it.
🔒 Never stores your API keys or your prompts. The proxy forwards your key to the real provider and keeps only token counts and dollars. No cloud account, no phone-home, no data leaves the machine it runs on. It's a safety brake, not a warranty — it dramatically cuts bill-shock; it can't promise a bill will never exceed a budget.
