Earns the spot for teams where contract-first API design is the core requirement."},{"model":"Gemini","reason":"Offers the absolute best developer experience for building OpenAPI/Swagger-compliant REST APIs via the poem-openapi crate. It compiles OpenAPI specs directly from Rust code types, dramatically reducing boilerplate while maintaining performance comparable to Axum. Its routing is clean, expressive, and supports modern features like WebSockets and Server-Sent Events out-of-the-box."}],"fixes":[{"model":"ChatGPT","fix":"Its smaller ecosystem and contributor base create more maintenance and integration risk than axum or Actix Web."},{"model":"Claude","fix":"Much smaller community and third-party middleware pool than the top three; if you don't need its OpenAPI machinery, Axum does everything else with more ecosystem support."},{"model":"Gemini","fix":"The community and ecosystem are significantly smaller than Axum and Actix-web, meaning developers have fewer third-party integrations and must write more custom code for edge cases."}],"updated":"2026-07-16","api":"https://modelsagree.com/api/v1/best/best-rust-frameworks-for-high-performance-apis.json"}],"page":"https://modelsagree.com/product/poem","check":"https://modelsagree.com/check?q=Poem","updated":"2026-07-16T21:15:59.371Z","attribution":"modelsagree.com, CC BY 4.0"}
