A free alternative to OpenRouter

OpenRouter is a hosted aggregator you pay per token (with a handful of rate-limited free models). If you want a free, open-source alternative, freellmpool pools the providers' own free tiers — Groq, Cerebras, NVIDIA, Gemini, Cloudflare, Mistral, Cohere and more — behind one OpenAI-compatible endpoint you run locally, with automatic failover, and it works with no API key to start (pip install freellmpool).

How they differ

	OpenRouter	freellmpool
Cost	Pay per token (some free models)	Free — pools providers' free tiers
Hosting	Hosted service	Local, open source (MIT)
Keyless start	No (account + key)	Yes (2 keyless providers)
Interface	API	CLI + Python library + proxy + MCP server
Failover	Yes	Yes

When to use which

• Use OpenRouter when you want one bill, hosted reliability, and access to many paid frontier models through a single account.
• Use freellmpool when you want to run on the free tiers for free, keep everything local and open source, install with pip, and use it from the CLI or as a library — not just an API. You can even point it at OpenRouter's free models as one of its pooled providers.

pip install freellmpool

freellmpool proxy                                    # OpenAI + Anthropic compatible

FAQ

Is there a free version of OpenRouter?

OpenRouter has a few rate-limited free models, but it's a paid hosted aggregator. For a fully free, open-source path, freellmpool pools the LLM providers' own free tiers behind one OpenAI-compatible endpoint and is keyless to start.

Can freellmpool use OpenRouter too?

Yes — OpenRouter is one of the 16 providers freellmpool can pool, so its free models become part of the failover pool alongside Groq, Cerebras, Gemini and the rest.
