Echo

High performance, extensible, minimalist Go web framework.

Echo is built on Go's standard net/http and interoperates with it through echo.WrapHandler and echo.WrapMiddleware. It adds the parts the standard library leaves to you: a fast radix-tree router, request binding with pluggable validation, a deep middleware ecosystem, and centralized error handling. Echo is actively maintained, and v5 is the current release line.

Getting started

Supported versions

• v5 is the current major version, released on 2026-01-18. See API_CHANGES_V5.md for the API changes from v4 and upgrade notes.
• v4 receives security updates and bug fixes until 2026-12-31.

See ROADMAP.md for where Echo is heading and the version support policy.

Installation

go get github.com/labstack/echo/v5

Echo supports the three most recent Go releases and may work with older ones.

Example

package main

import (
	"log/slog"
	"net/http"

	"github.com/labstack/echo/v5"
	"github.com/labstack/echo/v5/middleware"
)

func main() {
	// Echo instance
	e := echo.New()

	// Middleware
	e.Use(middleware.RequestLogger()) // log requests with log/slog
	e.Use(middleware.Recover())       // recover from panics and return an error

	// Routes
	e.GET("/", hello)

	// Start server
	if err := e.Start(":8080"); err != nil {
		slog.Error("failed to start server", "error", err)
	}
}

// Handler
func hello(c *echo.Context) error {
	return c.String(http.StatusOK, "Hello, World!")
}
