Azugo is web framework built on top of Fasthttp and multiple other libraries to be fast and memory efficient. It’s designed to allow fast development but still be easily extendable where it makes sense.


It requires Go 1.18 or higher. You can install it using command:

go get

First steps

Simple web application using default middlewares can be created using such code:

package main

import (

func main() {
  app, err := server.New(nil, server.ServerOptions{
    AppName: "Simple web app",
  if err != nil {

  app.Get("/", func(ctx *azugo.Context) {
    ctx.Text("Hello, World!")


Default middlewares

When using Azugo server package it is created with provided server options using default middlewares:

  • Client IP address detection from trusted proxies (by default single proxy from localhost are trusted)
  • Request logging
  • Prometheus metrics
  • CORS headers based on configuration

To see how to get started follow this guide: Getting started .

Default configuration environment variables

There are multiple built-in environment variables that can be used to configure your application.

This is the list of most commonly needed environment variables:

  • ENVIRONMENT - Current environment the service is run in. By default production environment will be used. Allowed values are:
    • Development
    • Staging
    • Production
  • SERVER_URLS - List of URLs that server will listen on separated by semicolon (;), ex. http://localhost:3000. By default server will listen on
  • BASE_PATH - If service will be hosted under subpath this will be used as base path for all routes.
  • REVERSE_PROXY_TRUSTED_IPS - list of trusted proxy server IP addresses or network masks separated by semicolon (;). By default only is trusted.
  • REVERSE_PROXY_LIMIT - Number of chained reverse proxy servers trusted. By default only 1 reverse proxy is trusted.
