Macaron Build Status

Macaron Logo

Package macaron is a high productive and modular web framework in Go.

Getting Started

The minimum requirement of Go is 1.6.

To install Macaron:

go get

The very basic usage of Macaron:

package main

import ""

func main() {
	m := macaron.Classic()
	m.Get("/", func() string {
		return "Hello world!"


  • Powerful routing with suburl.
  • Flexible routes combinations.
  • Unlimited nested group routers.
  • Directly integrate with existing services.
  • Dynamically change template files at runtime.
  • Allow to use in-memory template and static files.
  • Easy to plugin/unplugin features with modular design.
  • Handy dependency injection powered by inject.
  • Better router layer and less reflection make faster speed.


Middlewares allow you easily plugin/unplugin features for your Macaron applications.

There are already many middlewares to simplify your work:

  • render - Go template engine
  • static - Serves static files
  • gzip - Gzip compression to all responses
  • binding - Request data binding and validation
  • i18n - Internationalization and Localization
  • cache - Cache manager
  • session - Session manager
  • csrf - Generates and validates csrf tokens
  • captcha - Captcha service
  • pongo2 - Pongo2 template engine support
  • sockets - WebSockets channels binding
  • bindata - Embed binary data as static and template files
  • toolbox - Health check, pprof, profile and statistic services
  • oauth2 - OAuth 2.0 backend
  • authz - ACL/RBAC/ABAC authorization based on Casbin
  • switcher - Multiple-site support
  • method - HTTP method override
  • permissions2 - Cookies, users and permissions
  • renders - Beego-like render engine(Macaron has built-in template engine, this is another option)
  • piwik - Server-side piwik analytics

Use Cases

  • Gogs: A painless self-hosted Git Service
  • Grafana: The open platform for beautiful analytics and monitoring
  • Peach: A modern web documentation server
  • Go Walker: Go online API documentation
  • Switch: Gopm registry
  • Critical Stack Intel: A 100% free intel marketplace from Critical Stack, Inc.

An single variadic macaron.RenderOptions struct can be optionally provided to configure HTML rendering. The default directory for templates is "templates" and the default file extension is ".tmpl" and ".html".

This will clear any current middleware handlers, and panics if any of the handlers is not a callable function

Useful if you want to control your own HTTP server. Be aware that none of middleware will run without registering any router.

Middleware Handlers are invoked in the order that they are added.
