CodeMirror is an open-source project shared under an MIT license. It is the editor used in the dev tools for both Firefox and Chrome, Light Table, Adobe Brackets, Bitbucket, and many other projects.
Development and bug tracking happens on github (alternate git repository). Please read these pointers before submitting a bug. Use pull requests to submit patches. All contributions must be released under the same MIT license that CodeMirror uses.
Discussion around the project is done on a mailing list. There is also the codemirror-announce list, which is only used for major announcements (such as new versions). If needed, you can contact the maintainer directly.
A list of CodeMirror-related software that is not part of the main distribution is maintained on our wiki. Feel free to add your project.
The desktop versions of the following browsers,
in standards mode (HTML5
recommended) are supported:
|Firefox||version 4 and up|
|Safari||version 5.2 and up|
|Internet Explorer||version 8 and up|
|Opera||version 9 and up|
Modern mobile browsers tend to partly work. Bug reports and patches for mobile support are welcome, but the maintainer does not have the time or budget to actually work on it himself.
