Get started — it's free View on GitHub →

npm install -g @ryanisavibecoder/ccr

› ccr "the rate limiter is dropping requests under burst load.

find the bug in src/limiter.ts and fix it. add a test that

covers the burst case. don't run anything yet — show me

the diff first."

ccr is reading src/limiter.ts · src/limiter.test.ts · 4 imports

Found it. The token bucket refills on every request instead of every tick, so concurrent calls all see the pre-refill state. Here's the fix:

src/limiter.ts−2 +5

42   consume(n = 1) {
43−    this.tokens = Math.min(this.cap, this.tokens + this.rate);
44−    if (this.tokens < n) return false;
43+    const now = performance.now();
44+    const elapsed = (now - this.last) / 1000;
45+    this.tokens = Math.min(this.cap, this.tokens + elapsed * this.rate);
46+    this.last = now;
47+    if (this.tokens < n) return false;
48     this.tokens -= n;

Reads your repo

Indexes files, follows imports, surfaces what matters.

Proposes diffs

Shows you exactly what changes before anything touches disk.

Runs commands

Asks before executing. Approve, deny, or edit on the fly.

Free isn't a trick.

CCR routes requests across a handful of LLM providers — Groq, Together AI, Cerebras, OpenRouter — and aggregates their free tiers so you don't have to manage API keys, top up balances, or pick a model on a Tuesday. Sign up, install, and it works.

We pay nothing extra to operate it; you pay nothing to use it. If a provider's free tier ever disappears, we route around it. The day that becomes impossible we'll tell you, in plain English, on this page.
