Project Mission

Project mission is to provide easy to use, powerful, C (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 running on a Windows or Linux PC. It is available as single executable, no installation is required.

Where to find the official version?

End users can download CivetWeb binaries / releases from here on GitHub https://github.com/civetweb/civetweb/releases or SourceForge https://sourceforge.net/projects/civetweb/

Developers can contribute to CivetWeb via GitHub https://github.com/civetweb/civetweb

Due to a bug in Git for Windows V2.24 CivetWeb must be used with an earlier or later version (see also here).

Bugs and requests should be filed on GitHub https://github.com/civetweb/civetweb/issues

New releases are announced on Google Groups https://groups.google.com/d/forum/civetweb

Formerly some support question and discussion threads have been at Google groups. Recent questions and discussions use GitHub issues.

Source releases can be found on GitHub https://github.com/civetweb/civetweb/releases

Overview

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

• Forked from Mongoose in 2013, before it changed the licence from MIT to commercial + GPL. A lot of enhancements have been added since then, see RELEASE_NOTES.md.
• Maintains the liberal, permissive, commercial-friendly, MIT license
• Project is free from copy-left licenses, like GPL, because you should innovate without restrictions.
• Works on Windows, Mac, Linux, UNIX, IOS, Android, Buildroot, and many other platforms.
• Scripting and database support (CGI, Lua Server Pages, Server side Lua scripts, Lua SQLite database, Server side JavaScript). This provides a ready to go, powerful web development platform in a one single-click executable with no dependencies. 0
• Support for CGI, SSI, HTTP digest (MD5) authorization, WebSocket, WebDAV.
• Experimental HTTP/2 support.
• HTTPS (SSL/TLS) support using OpenSSL.
• Optional support for authentication using client side X.509 certificates.
• Resumed download, URL rewrite, file blacklist, IP-based ACL.
• Can run as a Windows service or systemd service.
• Download speed limit based on client subnet or URI pattern.
• Simple and clean embedding API.
• The source is in single file for drop in compilation.
• Embedding examples included.
• HTTP client capable of sending arbitrary HTTP/HTTPS requests.
• Websocket client functionality available (WS/WSS).

This project is very easy to install and use. Please read the documentation and have a look at the examples.

Recent questions and discussions usually use GitHub issues. Some old information may be found on the mailing list, but this information may be outdated.

Feel free to create a GitHub issue for bugs, feature requests, questions, suggestions or if you want to share tips and tricks. When creating an issues for a bug, add enough description to reproduce the issue - at least add CivetWeb version and operating system. Please see also the guidelines for Contributions and the Security Policy

Contributions

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 have been developed independently. By now the code base differs, so patches cannot be safely transferred in either direction.

Some guidelines can be found in docs/Contribution.md.

Authors

CivetWeb was forked from the last MIT version of Mongoose in August 2013. Since then, CivetWeb has seen many improvements from various authors (Copyright (c) 2013-2021 the CivetWeb developers, MIT license).

A list of authors can be found in CREDITS.md.

CivetWeb is based on the Mongoose project. The original author of Mongoose was Sergey Lyubka(2004-2013) who released it under the MIT license. However, on August 16, 2013, Mongoose was relicensed to a dual GPL V2 + commercial license and CiwetWeb was created by Thomas Davis (sunsetbrew) as "the MIT fork of mongoose". The license change and CivetWeb fork was mentioned on the Mongoose Wikipedia page as well, but it's getting deleted (and added again) there every now and then.

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.
