No subscription. No shared keys. No rate limit hell. The big AI labs (Groq, Cerebras, Gemini, Mistral...) are quietly giving away insane free tiers. But plug them directly into Cursor and you get: 429s that break your flow Dead keys with no warning Context window crashes mid-session Nimbus fixes this. It runs on localhost:7766 and races all your free API keys against each other. Every request goes to whoever responds first. If one provider 429s, the next one catches it automatically. What you're actually getting for free: Cerebras 1M tokens/day ~$200/mo
Gemini 1,500 req/day ~$200/mo
Groq 14K req/day ~$150/mo
Fireworks 60 RPM ~$150/mo
SambaNova 30 RPM ~$100/mo
Mistral free tier ~$75/mo
+ 3 more Total: ~$975/mo. Free. Forever. One-liner to run it: bunx github:Jaax-Labs/nimbus-router Works with Cursor, Continue.dev, Zed, Cline, and more.
