One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements.
A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one.
Rust is a systems programming language that runs fast, prevents segmentation faults, and guarantees thread safety. It accomplishes these goals by being memory safe without using garbage collection. The language enables developers to write programs with the performance and control of a low-level language, but with the powerful abstractions of a high-level language.
Here’s our verdict on the best free and open source Rust web micro-frameworks. Only free and open source software is included here.

Let’s explore the 8 Rust web micro-frameworks. For each program we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources.
| Rust Web Micro-Frameworks | |
|---|---|
| Actix Web | Powerful, pragmatic, and extremely fast web framework with a few twists |
| Salvo | Powerful and simplest web server framework |
| Abscissa | Many features with minimal dependencies and security conscious |
| Rouille | Designed to be intuitive and doesn't employ middlewares |
| Tide | Mnimal and pragmatic Rust web application framework |
| Micro Http | Lightweight and modular HTTP server implementation |
| Spair | Small and fast frontend framework |
| vial | Small web "framework" for making small web sites |
