| Fallbacks | Manifest automatically retries another provider when a selected provider fails. | Ordered fallback chains and per-provider circuit breakers help requests continue when a provider degrades. |
| Integrations | Manifest connects API keys, paid subscriptions, local models, and custom endpoints; named local integrations include Ollama, llama.cpp, and LM Studio. | Provider options include API keys, OAuth subscriptions, compatible custom endpoints, and self-hosted local models including Ollama, LM Studio, and llama.cpp. |
| Product | Manifest is an open-source LLM gateway that routes requests, provides fallbacks, repairs failing requests with Autofix, and tracks spending. | Polyrouter is an open-source LLM gateway that puts one endpoint in front of multiple model providers. |
| Security | Manifest states that data in transit uses TLS, passwords are hashed, and Gateway provider credentials are encrypted with AES-256-GCM. | Provider and notification credentials are encrypted at rest, and user-supplied URLs are checked against private and metadata address ranges. |
| Support | Free includes community support through Discord, Pro includes basic platform and billing support, and Enterprise includes dedicated Slack and email support. | The maker directs bug reports, feature requests, and questions to GitHub. |

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.
