Manifest vs WSO2 AI Gateway

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.

WSO2 AI Gateway governs AI APIs and generative AI services with usage visibility, guardrails, prompt management, and semantic caching. Its out-of-the-box language-model support includes OpenAI, Mistral AI, and Azure OpenAI. Built-in controls check prompts semantically, mask PII, validate JSON Schema and regex rules, limit output length, and check URLs; Azure Content Safety and AWS Bedrock Guardrails are listed as external integrations. The gateway monitors backend limits by request and token count and manages subscription access. Prompt templates can standardize inputs and add role or context instructions. Model-level analytics and semantic caching are intended to help reduce repeated calls and improve response speed and cost efficiency. WSO2 also describes converting REST APIs into MCP-compatible tools and governing access to MCP servers. Moesif-powered analytics tracks AI and agent traffic. Deployment can be on-premises or in the cloud. The SaaS-only 30-day trial costs nothing and includes 1M AI Gateway events, five managed LLM APIs, and one hybrid gateway. Growth costs $119 a month; Enterprise pricing is custom.
