a3m-router vs freellmapi
Self-hosted LLM request routers compared
a3m-router and freellmapi are self-hosted TypeScript gateways that route LLM requests through a shared API. a3m-router emphasizes routing strategies, ensembles, and provider failover, while freellmapi focuses on combining free provider tiers and custom endpoints with quota and key management.
a3m-router: Route LLM Requests Across Models
A3M Router is a TypeScript, self-hosted LLM gateway built around Jev System One single-pass routing. It directs OpenAI-compatible requests to models and providers based on the task, with failover and optional parallel ensembles.
freellmapi: Route LLM Requests Through One API
FreeLLMAPI is a self-hosted TypeScript router that combines free LLM provider accounts and custom OpenAI-compatible endpoints behind one API. It selects models, tracks quotas, and retries across providers, mainly for personal experimentation and development.

Key differences
- a3m-router offers heuristic and ML-based routing, while freellmapi routes using model selection, quota tracking, key rotation, and fallback.
- a3m-router describes semantic caching and optional parallel ensembles; freellmapi highlights a dashboard, usage analytics, and client and MCP helpers.
- a3m-router lists support for 80+ providers with runtime availability checks, while freellmapi combines configured free-tier providers with custom OpenAI-compatible endpoints.
- freellmapi supports additional Anthropic, Gemini, and optional Ollama-compatible interfaces, while a3m-router describes an OpenAI-compatible chat completions endpoint.
- freellmapi is positioned for personal experimentation and explicitly not for production; a3m-router is aimed at teams operating routing infrastructure themselves and advises validating capabilities before production use.
- Both projects are TypeScript and MIT-licensed; freellmapi describes local, Docker, and desktop installation options, while a3m-router provides CLI commands for serving and route and provider checks.
Choose a3m-router if you…
- need heuristic or ML-based routing, provider failover, or semantic caching.
- want optional parallel ensembles to compare and combine provider responses.
- plan to operate a self-hosted routing gateway for a team.
Choose freellmapi if you…
- want to combine free provider tiers and custom OpenAI-compatible endpoints behind one API.
- need quota tracking, key rotation, a dashboard, or compatible client and agent helpers.
- are experimenting with models or prototyping workflows rather than running production inference.
