About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Actix Web is an asynchronous web framework for Rust. It provides routing, middleware, HTTP/1.x and HTTP/2, WebSockets, streaming, compression, multipart handling, static files, and integration with the Tokio ecosystem.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Key features

Build HTTP APIs with typed routing and extractors

Routes can be declared with macros or builders, while path, JSON, and other request data are extracted into Rust types and handled by async functions.

Sources: [1]

Handle HTTP/2, WebSockets, streaming, and compression in one stack

The framework supports HTTP/1.x, HTTP/2, WebSockets, streaming, multipart data, static assets, and Brotli/gzip/zstd compression.

Sources: [1][2]

Integrate with Tokio and middleware

Actix Web is compatible with Tokio and provides middleware patterns for logging, sessions, CORS, and other cross-cutting concerns.

Sources: [1]

Best fit

Fits Rust teams building APIs and real-time backends

It is relevant when REST-style APIs, WebSockets, or streaming services should use Rust's type system and a Tokio-based asynchronous runtime.

Sources: [1]

Before adoption

Version 4.15.0 requires Rust 1.88 or newer

The workspace and actix-web package set the minimum supported Rust version to 1.88, so older pinned toolchains must be upgraded first.

Sources: [2]

Experimental features may break between releases

The README explicitly says features prefixed experimental can receive breaking changes in any release. experimental-introspection should be treated as local diagnostic tooling rather than a stable production contract.

Sources: [1][3]

Licensing is MIT OR Apache-2.0

The workspace declares the SPDX expression MIT OR Apache-2.0 and ships both license files. Distribution should follow the selected license's conditions.

Sources: [2][4][5]

Supplemental curator note

Actix Web is a strong fit for low-overhead Rust APIs and real-time services. Version 4.15.0 requires Rust 1.88+, and features prefixed experimental may break in any release, so production use should avoid or tightly pin them.

Try it in 3 steps

  1. 1

    Create a Rust project

    Create a new binary project with Rust 1.88 or newer.

    cargo new actix-demo && cd actix-demo
  2. 2

    Add Actix Web 4.15.0

    Pin the published version and place the README Hello World example in src/main.rs.

    cargo add actix-web@4.15.0
  3. 3

    Run and verify the server

    Open http://127.0.0.1:8080/hello/world and verify the route and response.

    cargo run
