OmniRoute

OmniRoute is a free, open-source AI gateway that routes requests across 160+ AI providers through a single OpenAI-compatible endpoint, with zero downtime via smart 4-tier auto-fallback (Subscription → API Key → Cheap → Free). It features a built-in 5-mode prompt compression pipeline that saves 15-75% tokens automatically on every request, a 3-level proxy system for bypassing geographic restrictions, and full MCP Server and A2A Protocol support. The project is written in 100% TypeScript, backed by 4,690+ automated tests, and runs on Web, Desktop (Electron), Android (Termux), and as a PWA.

• Smart 4-Tier Auto-Fallback — Install via npm install -g omniroute, then configure a combo chain in the dashboard to automatically route Subscription → API Key → Cheap → Free providers with zero downtime.
• Prompt Compression (5 Modes) — Enable in Dashboard → Settings → Compression; choose from Off, Lite (~15%), Standard/Caveman (~30%), Aggressive (~50%), or Ultra (~75%) to reduce token usage on every request transparently.
• 160+ Provider Support — Connect OAuth providers (Claude Code, Codex, Gemini CLI, GitHub Copilot, Cursor), API key providers (OpenAI, Anthropic, DeepSeek, Groq, xAI, Mistral, and 120+ more), and 11 genuinely free providers including Kiro, Qoder, Pollinations, and LongCat.
• Format Translation — OmniRoute automatically translates between OpenAI, Claude, Gemini, and Responses API formats so any OpenAI-compatible tool works with any provider.
• MCP Server (29 Tools) — Run omniroute --mcp for stdio transport, or connect via SSE/HTTP; supports 10 granular permission scopes and a SQLite-backed audit trail.
• A2A Protocol — Full JSON-RPC 2.0 + SSE streaming agent-to-agent protocol with task lifecycle management and an agent card at /.well-known/agent.json.
• 3-Level Proxy System — Configure global, per-provider, or per-API-key proxies in the dashboard; includes a built-in 1proxy free marketplace with 500+ community-shared proxies and TLS fingerprint spoofing.
• 10 Multi-Modal APIs — One endpoint covers chat completions, embeddings, image generation, video, music, audio TTS/STT, reranking, moderation, and web search.
• Full Observability — Unified 4-tab log dashboard (request, proxy, audit, console), p50/p95/p99 telemetry, per-token cost tracking, budget controls, and a built-in LLM evaluation framework.
• Multi-Platform — Runs as an npm global package, Docker image (AMD64 + ARM64), Electron desktop app, Android via Termux, or as a PWA; available in 40+ languages with RTL support.
