The Open Source LLM Router for AI Agents·manifest.build

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.

What it's for

Connecting AI agents and coding assistants to multiple LLM providers through one endpointUsing existing AI subscriptions (Claude Pro, ChatGPT Plus, Gemini Advanced) with agentsAutomatically retrying/fallback when a provider is down or rate-limitedRepairing broken or invalid provider requests before they reach the agent (Auto-fix)Routing requests to local models (Ollama, LM Studio, llama.cpp) instead of the cloudTracking spend and usage per agent, key, and providerSetting budgets, rate limits, and custom routing tiers per agent
