Local inference backends (oMLX, Ollama, LM Studio) configured as
provider_nodes have no health monitoring. When a local provider is
down, OmniRoute waits the full timeout before failing.
This adds a background health check that polls local provider_nodes:
- GET /models with 5s timeout for each local node (localhost only)
- In-memory health cache (no DB migration needed)
- Promise.allSettled for parallel checks (one slow node doesn't block)
- Exponential backoff on failures: 30s → 60s → 120s → 300s max
- Reset to 30s on first success after failure
- State transition logging (healthy ↔ unhealthy)
- Expose health status via GET /api/monitoring/health (localProviders)
- Auto-init on first import (same pattern as tokenHealthCheck)
- 401 treated as healthy (server up, auth required)
- isNodeHealthy() returns true if never checked (optimistic default)
OmniRoute is an intelligent API gateway that unifies 20+ AI providers behind a single
OpenAI-compatible endpoint. Features include intelligent routing with 6 strategies,
multi-format translation (OpenAI/Claude/Gemini/Responses API), circuit breakers,
semantic caching, combo fallback chains, real-time health monitoring, and a full
dashboard with provider management, analytics, and CLI tool integration.
Key highlights:
- 20+ providers (Claude Code, Codex, Gemini CLI, GitHub Copilot, iFlow, Qwen, Kiro, etc.)
- 6 routing strategies (Fill First, Round Robin, P2C, Random, Least Used, Cost Optimized)
- Export/Import database backup with full archive support
- Translator Playground with 4 modes (Playground, Chat Tester, Test Bench, Live Monitor)
- 100% TypeScript across src/ and open-sse/
- Docker support with multi-stage builds
- Comprehensive documentation and 9 dashboard screenshots
