Light Table is a next generation code editor that connects you to your creation with instant feedback. Light Table is very customizable and can display anything a Chromium browser can.

This is a development branch and is not clean like master and can have many breakages.


Prebuilt binaries are available through To build and use a developer version of Light Table see these instructions.

For OSX users, the install process involves the following steps until we officially sign our OSX App:

  • In Finder, Ctrl-click on and select Open.
  • When you see this prompt about LightTable being unidentified, click Open.
  • If Ctrl-click doesn't work for you, open System Preferences > Security & Privacy > General, temporarily change "Allow apps downloaded from:" to Anywhere and double click on



Light Table has a powerful plugin system that allows almost any aspect of the editor to be extended and customized. With over 100+ plugins, the community is able to offer eval support for new languages, create domain-specific IDEs and much more. If you're interested in writing your own plugin, see the Write a Plugin and Submit a Plugin docs. For an example ClojureScript plugin, see LightTable-Declassifier.


Want to ask a question or just say hi? Please do :). Our mailing list is the Light Table Google group. We also hang out in #lighttable on Freenode IRC.

For Developers

LightTable is primarily written in ClojureScript. If you aren't familiar with it, check out David Nolen's tutorial.
