The Open Source LLM Router for AI Agents

---

What is Manifest LLM Gateway?

Manifest LLM Gateway is an open-source LLM gateway for AI agents and apps. Connect your API keys, subscriptions, and local models to one OpenAI-compatible endpoint, and each query goes to the right model. No single-provider lock-in.

• 🔀 Custom Routing: API keys, Subscriptions, Local models, Custom providers
• 💾 Full Body Logs for Success and Error Messages
• 📊 Track every single dollar, setup notifications and limits
• 🚑 Fallback on different models when queries fail, Self-heals your bad requests

Quick start

Cloud version

Go to app.manifest.build and follow the guide.

Self-hosted

Manifest ships as a Docker image. One command:

bash <(curl -sSL https://raw.githubusercontent.com/mnfst/llm-gateway/main/docker/install.sh)

Open http://localhost:2099 and sign up — the first account you create becomes the admin. Full self-hosting guide: docker/DOCKER_README.md.

Deploy with one click

Platform	Notes
Railway	Best path. Template includes Manifest, PostgreSQL, and S3-compatible storage for request recordings.
Render	Blueprint includes Manifest, PostgreSQL, and a persistent recording disk.
DigitalOcean	App Platform and PostgreSQL; provide a private Space for recordings.
AWS	CloudFormation provisions ECS, RDS, and a private recording bucket.
GCP	DeployStack provisions Cloud Run, Cloud SQL, and Cloud Storage.

Every deployment path now uses durable request-recording storage. Railway, AWS, GCP, and Fly.io provision it natively; Render, Coolify, Easypanel, Docker, and Apple Containers mount persistent storage. DigitalOcean, Heroku, and Koyeb collect external S3-compatible settings during setup. Volume-backed templates are single-instance; use S3-compatible storage before scaling horizontally.

Full deployment guides: Railway, Render, DigitalOcean, AWS, GCP, Fly.io, Coolify, Easypanel, Heroku, Koyeb, and Apple Containers.

The old npm-based self-hosting path is no longer supported. Use the Docker image or one of the deployment guides above.

Providers

Manifest connects to 300+ models through 35 built-in provider connections plus any custom OpenAI/Anthropic-compatible endpoint. Bring your own API key, reuse one of 18 subscription flows, or run models locally. Everything is routed through the same OpenAI-compatible endpoint — send "model": "auto" and Manifest picks the model.

Provider catalogs are discovered dynamically when credentials are connected. The examples below are representative, not exhaustive.
