| Integrations | Manifest connects API keys, paid subscriptions, local models, and custom endpoints; named local integrations include Ollama, llama.cpp, and LM Studio. | The subscription guide lists integrations for Claude Code, CodeX, Cline, VS Code Copilot, OpenCode, Cherry Studio, Obsidian, Dify, and Open WebUI. |
| Model routing | Sending model auto applies routing rules, fallback behavior and per-harness spending limits. | Its intelligent routing analyzes requests and task characteristics to select a model based on suitability and cost. |
| Observability | Usage views show spending, selected models, token consumption and failed requests for each harness. | The platform provides API request logs and analytics for costs, usage, and performance. |
| Support | Free includes community support through Discord, Pro includes basic platform and billing support, and Enterprise includes dedicated Slack and email support. | ZenMux lists technical support by email and says it typically responds within 24 hours. |

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.
