Overview
Poem is a web framework for Rust. It composes routing, extractors, responses, and middleware into HTTP servers and can add WebSockets, SSE, sessions, TLS, static files, and Tower compatibility through optional features.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Key features
Compose HTTP endpoints from routes, handlers, and extractors
Routes bind paths to handlers, while extractors such as Path map request data into Rust types. Middleware can wrap Endpoints to apply cross-cutting request and response behavior.

Best fit
Fits Rust backends that want HTTP-server capabilities in one framework
It suits API servers and web applications that prefer to manage routing, middleware, streaming, and TLS within one framework while retaining Tower Service and Layer compatibility.

Before adoption
Separate stable 3.1.12 from the unreleased 4.0 line and its breaking changes
Stable Poem 3.1.12 has Rust 1.85 as its MSRV. The default branch targets unreleased 4.0.0 with Rust 1.94 and breaking integration/dependency changes, so upgrades should follow the dedicated migration guide.

Supplemental curator note
Poem is a fit when a backend wants routing, streaming, sessions, TLS, and other HTTP-server features in one framework. The default branch is moving toward unreleased 4.0, so do not copy master-branch APIs directly into stable 3.1.x applications.

Start the Hello World example
Run the official examples-workspace Hello World server, which listens on port 3000.
cd examples && cargo run -p example-hello-world - 3
Check the path-parameter response
Send a request from another terminal and confirm that the Path extractor and handler return hello: world.
curl -fsS http://127.0.0.1:3000/hello/world
