In their own words
Manifest
Manifest is an open-source LLM gateway for routing model requests, switching providers, repairing certain failures, and tracking inference spending. It provides one endpoint compatible with OpenAI and Anthropic models and subscriptions. When a provider goes down, fallback routing retries through another provider. Autofix repairs malformed requests and resends them when retries alone cannot resolve the error. Observability shows spending by harness, which models handled requests, and what failed. Manifest connects API keys, paid subscriptions, local models, and custom endpoints, including Ollama, llama.cpp, and LM Studio. The self-hosted gateway runs with Docker, works offline, requires no account, and supports amd64 and arm64. Self-hosted routing and request data remain on customer servers except documented telemetry and Autofix flows. The Cloud Free plan allows 10,000 routed requests per calendar month and cannot reach local models on the user's machine. Free includes unlimited self-hosted use; Pro costs $19 a month with unlimited Cloud requests and 365-day dashboard retention.
