What LiveCodes is
LiveCodes is a free, open-source browser playground for prototyping with more than 90 languages, frameworks, and processors. Its editor provides code completion, go-to-definition, multi-cursor editing, formatting, and Vim or Emacs bindings; mobile devices use a touch-friendly CodeMirror 6 editor. Users can add external scripts and stylesheets, search npm libraries and Google Fonts, and import npm modules without npm installs. Projects can come from GitHub, GitLab, JS Bin, web page DOM, or ZIP files, then be exported as HTML, JSON, ZIP, gists, CodePen projects, or JSFiddle projects. LiveCodes includes a console, compiled-code viewer, and test runner. Playgrounds can be embedded and controlled through SDKs for JavaScript/TypeScript and several frameworks. Projects are private by default, with optional sharing, broadcasting, synchronization, backup, and restoration. It supports web, API, and self-hosted use.
