Overview
Echo is a framework for building web applications and REST APIs in Go. It interoperates with the standard net/http package while adding a fast router, request binding, middleware, response helpers, and centralized error handling. It fits projects that want to start small and compose cross-cutting behavior at the route or group level.
Features and best fit

Key features
Compose HTTP behavior with routes, groups, and layered middleware
The radix-tree router groups APIs and lets middleware run globally, for a group, or for one route. Echo also provides JSON, XML, and form binding, HTTP response helpers, centralized error handling, and rendering through a chosen template engine.

Add framework facilities while retaining net/http interoperability
echo.WrapHandler and echo.WrapMiddleware incorporate standard handlers and middleware. TLS, HTTP/2, WebSocket support, logging, and official or third-party middleware can be adopted as needed, allowing gradual integration with standard-library code.

Best fit
Fits lightweight Go APIs that organize shared concerns as middleware
Echo suits teams separating authentication, recovery, logging, and validation from route handlers while growing REST APIs or microservices with a consistent structure. It can also reduce routing and error-handling boilerplate without discarding existing net/http components.

Before adoption
Make v5 migration and proxy trust boundaries explicit
Version 5.4.0 fixes several security issues and changes how trusted peers, X-Forwarded-Proto, X-Real-IP, MethodOverride, JSONP, and static-file paths behave. Deployments behind public-address proxies or load balancers must configure trusted ranges and test middleware order against the real request path. v4 receives security and bug fixes through the end of 2026, but v5 includes public API changes. Echo uses the MIT License.

Supplemental curator note
Echo can grow from a small API into a middleware-heavy service, but forwarded-header and static-file boundaries are security-sensitive configuration. A v5 migration should test scheme and client-IP behavior behind real proxies, not stop at successful compilation.

Create a Go module and add Echo v5.4.0
Pin the version while adding Echo to a minimal project.
mkdir echo-demo && cd echo-demo go mod init example.com/echo-demo go get github.com/labstack/echo/v5@v5.4.0 - 2
Write a Hello World server
Define a route and handler with the v5 API shown in the official README.
printf 'package main\n\nimport (\n "log/slog"\n "net/http"\n "github.com/labstack/echo/v5"\n)\n\nfunc main() {\n e := echo.New()\n e.GET("/", func(c *echo.Context) error {\n return c.String(http.StatusOK, "Hello, World!")\n })\n if err := e.Start(":8080"); err != nil {\n slog.Error("failed to start server", "error", err)\n }\n}\n' > main.go - 3
Start the local server
From another terminal, run curl http://localhost:8080/ and confirm the response.
go run .
