Poem
What ChatGPT, Claude, Gemini & Grok actually say · July 2026
The verdict
Poem appears in 1 AI-ranked category — best position #5 for rust frameworks for high-performance apis.
Strong API ergonomics, capable middleware and extractors, WebSocket/SSE support, and especially productive contract-first development through Poem OpenAPI make it excellent for documented JSON services.
Claude The strongest built-in OpenAPI story in Rust — poem-openapi generates spec-first, type-checked APIs with far less ceremony than utoipa bolted onto Axum; clean Tokio-based design, solid performance, and adoption in serious projects (e.g. Apache-ecosystem tooling). Earns the spot for teams where contract-first API design is the core requirement.
Gemini 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.
Where Poem falls short, per the models
- GPT Its smaller ecosystem and contributor base create more maintenance and integration risk than axum or Actix Web.
- Claude 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.
- Gemini 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.
Top alternatives per the models: Axum · Actix-web · Actix Web · Salvo
