Project Mission

Project mission is to provide easy to use, powerful, C/C++ embeddable web server with optional CGI, SSL and Lua support. CivetWeb has a MIT license so you can innovate without restrictions.

CivetWeb can be used by developers as a library, to add web server functionality to an existing application. It can also be used by end users as a stand-alone web server. It is available as single executable, no installation is required.

Where to find the official version?

End users can download CivetWeb releases at SourceForge

Developers can contribute to CivetWeb via GitHub

Trouble tickets should be filed on GitHub

Announcements are at Google Groups Some older support and discussion threads are there as well. However, recently support questions and discussions are usually GitHub issues.

Source releases can be found on GitHub

A very brief overview can be found on GitHub Pages

Quick start documentation


CivetWeb keeps the balance between functionality and simplicity by a carefully selected list of features:

  • Liberal, commercial-friendly, permissive, MIT license
  • Free from copy-left licenses, like GPL, because you should innovate without restrictions.
  • Forked from Mongoose in 2013, before it changed the licence from MIT to commercial + GPL. A lot of enchancements have been added since that time, see
  • Works on Windows, Mac, Linux, UNIX, iPhone, Android, Buildroot, and many other platforms.
  • Scripting and database support (Lua scipts, Lua Server Pages, CGI + SQLite database, Server side javascript). This provides a ready to go, powerful web development platform in a one single-click executable with no dependencies.
  • Support for CGI, HTTPS (SSL/TLS), SSI, HTTP digest (MD5) authorization, Websocket, WEbDAV.
  • Optional support for authentication using client side X.509 certificates.
  • Resumed download, URL rewrite, file blacklist, IP-based ACL, Windows service.
  • Download speed limit based on client subnet or URI pattern.
  • Simple and clean embedding API.
  • The source is in single file to make things easy.
  • Embedding examples included.
  • HTTP client capable of sending arbitrary HTTP/HTTPS requests.
  • Websocket client functionality available (WS/WSS).

Optionally included software








This project is very easy to install and use. Please read the documentation and have a look at the examples. More information may be found on the mailing list.

Contributions are welcome provided all contributions carry the MIT license.

DO NOT APPLY fixes copied from Mongoose to this project to prevent GPL tainting. Since 2013, CivetWeb and Mongoose are developed independently. By now the code base differs, so patches cannot be safely transfered in either direction.

Some guidelines can be found in docs/


CivetWeb is based on the Mongoose project. The original author of Mongoose was Sergey Lyubka (Copyright (c) 2004-2013 Sergey Lyubka, MIT license).

However, in August 16, 2013, the license of Mongoose has been changed after writing and distributing the original code this project is based on. The license change and CivetWeb used to be mentioned on the Mongoose Wikipedia page as well, but it's getting deleted (and added again) there every now and then.

CivetWeb has been forked from the last MIT version of Mongoose. Since 2013, CivetWeb has seen many improvements from various authors (Copyright (c) 2013-2017 the CivetWeb developers, MIT license). A list of authors can be found in

Using the CivetWeb project ensures the MIT licenses terms are applied and GPL cannot be imposed on any of this code, as long as it is sourced from here. This code will remain free with the MIT license protection.
