labstack/echo
High performance, minimalist Go web framework
Echo is a mature, minimalist Go HTTP framework built around a fast radix-tree router. It sits between net/http and full-stack frameworks — you get routing, middleware, binding, and error handling without a lot of opinions about project structure. V5 shipped in January 2026 and is the current supported version.
The radix-tree router with static/parameterized/wildcard priority ordering is genuinely fast and handles edge cases (trailing slash, conflicting routes) better than most alternatives. Middleware scoping at root/group/route level is clean and composable — you can attach rate limiting to one route group without it leaking. The `echotest` package ships with the repo, so testing handlers without spinning up a server is first-class, not an afterthought. V4 gets security fixes through end of 2026, so existing codebases aren't stranded during an upgrade.
No built-in OpenAPI or schema generation — you're reaching for oapi-codegen or swaggo immediately on any serious API, which means your route definitions and your spec can drift. The generic context additions in V5 (`context_generic.go`) feel bolted on rather than designed from scratch, and the API_CHANGES_V5 doc is long enough that upgrading from V4 is a real afternoon, not a minor bump. Built-in rate limiting middleware stores state in-memory only — the moment you run two instances you need to replace it entirely. WebSocket support is present but thin; anything beyond basic echo/chat examples will have you writing most of the upgrade and frame handling yourself.
