Editor42

Free, open-source, MIT-licensed WYSIWYG HTML editor — an auditable fork of TinyMCE, the world's most popular rich text editor.

Editor42 is based on the last MIT-licensed release of TinyMCE and provides you the same power of rich text editing on your websites and in apps.

  • Secure. All known CVEs and security-related bugs are fixed and maintained.
  • Stable. Well-maintained editor with a dedicated team monitoring bug reports and fixing code.
  • Compatible. Easily switch from your current TinyMCE installation — same API, same configuration.
  • Auditable. Code changes are kept minimal, with a clear history traceable back to the original TinyMCE source.
  • Predictable. We focus strictly on security and bug fixes — no surprise breaking changes.

Migrating from TinyMCE​

From some point, TinyMCE changed its license from MIT to GPL. Editor42 is built from the latest MIT-licensed state of TinyMCE, so you get a maintained, secure editor under a permissive license without rewriting your integration.

You can migrate from any version of TinyMCE — the process is the same regardless of which release you are currently on, and in most cases the switch is seamless. All APIs, configuration options, plugins, and themes remain compatible.
