Pool the free tiers of 18 LLM providers (200+ live-validated, 300+ cataloged models) behind one OpenAI-compatible endpoint — as a CLI, a Python library, or a local proxy. Works with no API keys.
FAQ: where prompts go, ToS posture, failover, bans, and comparisons.
pip install freellmpool # or: pipx install freellmpool
Only dependency is httpx. Python 3.11+.
Fresh install to first free-model reply takes about 19 seconds on a clean Linux/Python 3.12 environment, with zero API keys:
python3 -m venv .venv
. .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install freellmpool
freellmpool ask --max-tokens 32 "Reply with one short sentence: freellmpool is ready."
CI runs the same path from this checkout with FREELLMPOOL_QUICKSTART_PACKAGE=. scripts/quickstart-test.sh.
Groq, Cerebras, NVIDIA NIM, Google Gemini, OpenRouter, GitHub Models, Cloudflare, Mistral, Cohere and others each give away a free tier — but each has its own SDK, rate limits, and daily cap. freellmpool puts them in one pool: it sends each request to a provider you have access to, fails over to the next when one is rate limited or down, and tracks per-day usage so you get the most out of every tier.
Several providers (Pollinations, OVHcloud, and Kilo Gateway) need no API key, so the quickstart above answers immediately.
Add keys for the other providers to unlock more models and higher limits.
| Tool | Keyless start | # providers | Failover | MCP server | CLI | Transcription | Local/self-hosted | License |
|---|---|---|---|---|---|---|---|---|
| **freellmpool** | Yes: Pollinations, OVHcloud, Kilo Gateway; LLM7 is key-optional | 18 built-in chat providers | Yes: tries the next provider on rate limits, timeouts, 5xx, empty replies, and transport errors | Yes: freellmpool mcp | Yes: freellmpool ask, tokenmax, providers, proxy, and more | Yes: OpenAI-compatible /v1/audio/transcriptions with provider failover | Yes: local Python package and local proxy | MIT |
| OpenRouter free models | No: OpenRouter account/API key required | One hosted OpenRouter account routing across many upstreams; the free-model router currently lists free variants | Yes: OpenRouter handles provider routing/fallbacks | Not a native MCP server; OpenRouter docs show MCP-client/tool patterns | No first-party local CLI in the docs checked | Yes: OpenRouter now documents audio transcription APIs | No: hosted service | Proprietary service |
| LiteLLM | No: bring provider keys or hosted LiteLLM credentials | 100+ LLM providers | Yes: router/fallbacks, including transcription fallbacks | Yes: LiteLLM Proxy includes an MCP Gateway | Yes: SDK/proxy command surface, not a one-shot free-model CLI | Yes: /audio/transcriptions support | Yes: self-host the proxy or use hosted LiteLLM | MIT for core repo; commercial license for enterprise-only pieces |
| FreeLLMAPI | No: add your own free-tier provider keys; keyless providers can be configured after setup | 16 free-tier providers plus custom OpenAI-compatible endpoints | Yes: fallback chain on 429, 5xx, and timeouts | No native MCP server in the README checked | Dashboard/server, desktop app, and Docker; no first-class one-shot CLI in the README checked | No: /v1/audio/* is listed as not yet supported | Yes: self-hosted Node/Docker proxy | MIT |
FreeLLMAPI predates this project, and the overlap is independent convergence: both projects noticed that legitimate free tiers are useful when treated carefully. freellmpool's niche is the keyless, pip-installable client for squeezing hosted free tiers from a CLI, library, local proxy, and MCP server; OpenRouter is the polished hosted route; LiteLLM is the mature bring-your-own-key gateway.
Table sources: freellmpool's catalog and proxy code in this repo; OpenRouter's quickstart, free-model, routing, and audio docs; LiteLLM's README, MCP docs, and audio transcription docs; FreeLLMAPI's README.
Is there a free, OpenAI-compatible LLM API gateway? Yes — freellmpool is a free, MIT-licensed gateway that exposes one OpenAI-compatible endpoint backed by the free tiers of 18 providers. pip install freellmpool and point any OpenAI client at the local proxy.
How do I use multiple free LLM APIs at once? freellmpool pools them: each request goes to a provider you have access to, fails over to the next when one is rate-limited or down, and tracks per-day usage so load spreads across tiers.
Can I run Claude Code or Codex on free models? Yes — the proxy speaks both the OpenAI and Anthropic APIs. Set OPENAI_BASE_URL or ANTHROPIC_BASE_URL to the proxy and run Codex, Claude Code, aider, Cline, Continue, or Cursor unchanged. For Claude Code, set CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1 so /v1/models is discovered through the Anthropic bridge. See freellmpool code <agent>. (Claude Code path is experimental: text + tools, no vision.)
Do I need an API key? No — Pollinations, OVHcloud, and Kilo Gateway work with no key, so a fresh install answers immediately. Add free keys for the other providers for more models and higher limits.
Is it free and open source? Yes, MIT-licensed. More at the project page.
