Manifest is an open source LLM router that connects AI agents and harnesses to any LLM provider in seconds. It routes requests to subscription-based providers, pay-per-token APIs, local models, or custom endpoints through a single OpenAI-compatible or Anthropic-compatible endpoint. It includes model fallbacks, an Auto-fix feature that repairs broken provider requests on the fly, and observability into request, token, and cost data. It can be used as a hosted Cloud service or self-hosted via Docker.
