## What it is
Salvo is a powerful yet simple async web framework for Rust, built on Hyper and Tokio. It offers tree-based routing, unified handler/middleware design, HTTP/1-3 support, auto TLS via ACME, and built-in OpenAPI generation.

## Use cases
- build a REST API in Rust
- serve a website with automatic HTTPS certificates
- create a WebSocket real-time server
- generate OpenAPI docs for a Rust backend
- write an HTTP/3 web service
- add middleware like rate limiting or JWT auth to a Rust server

## When to choose
- you want a Rust web framework with minimal boilerplate and simple handler functions
- you need HTTP/2 or HTTP/3 support out of the box
- you want built-in OpenAPI documentation generation
- you need automatic TLS/Let's Encrypt certificate management
- you want flexible nested routing with middleware at any level

## When to avoid
- your team is already invested in Axum or Actix with existing code
- you need the largest ecosystem of third-party examples and middleware
- you are not using Rust for your backend

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, http-server, routing, middleware, websocket, api-framework
- domain: web-development, backend, apis
- platform: rust, cross-platform
- tags: async, http3, openapi, tls, acme, tokio, hyper
