Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A Rust library for routing HTTP requests and writing request handlers, built on Tokio.
Open source · MIT
A Rust web server framework built from small composable filters for handling HTTP requests.
The short answer
Choose axum if you need…
- Rust developers building HTTP APIs or web services
- Teams already using the Tokio async runtime
- Developers who want modular, composable request handling
Choose warp if you need…
- Rust developers building HTTP APIs or web servers
- Developers who like composing small reusable request-handling pieces
- Projects that need routing, JSON or form handling, websockets, or static files in one framework
- Teams already using Tokio for asynchronous Rust code

What each one is
axum
axum is a Rust library for building web servers and APIs. You define routes that map URLs to handler functions, and axum handles extracting data from requests and turning return values into responses. The project emphasizes ergonomics and modularity, according to its description. The README provided here is truncated, so this summary relies mainly on the repository description and topics.
warp
warp is a web server framework for the Rust programming language. It lets developers describe what a request must look like (its path, headers, query string, or body) by combining small building blocks called filters, then write the code that answers matching requests. It is built on top of hyper, so it supports HTTP/1 and HTTP/2 and runs asynchronously.
Best for

- Developers who want modular, composable request handling

Strengths
axum
- Described as focused on ergonomics and modularity
- Actively maintained, with a recent push and a tagged release (axum-v0.8.9)
- Permissively licensed under MIT and widely starred on GitHub
warp
- Routing and request matching are expressed as composable filters, which the README presents as the core design
- Covers many common needs out of the box, including websockets, compression, and access logging
- Built on hyper, which the README says provides HTTP/1, HTTP/2, and async support
Not ideal for
axum
- People who are not writing Rust code, since it is a library rather than a ready-made application
- Beginners new to Rust, who may find its type-driven handler model hard to learn at first
- Projects needing a full-featured framework with built-in admin, ORM, or templating, since the README excerpt does not show these
warp
- People who do not write Rust, since the README only shows Rust examples
- Beginners new to both Rust and async programming, as the filter model and Tokio setup take time to learn
- Projects needing a long-term stability guarantee, since the latest release is v0.4.1 and the README does not describe its support policy
Trade-offs
axum
- The README excerpt is truncated, so detailed capabilities and setup steps could not be verified here
- Requires familiarity with Rust and async programming
- Release listed without binaries, so it is used as a dependency rather than downloaded
warp
- Requires working knowledge of Rust and the Tokio async runtime
- The README is brief and points to external docs and examples for detail
- The README does not state a stability or maintenance commitment beyond the latest release date
