# Editor Feature Matrix

Studio features a large set of language editors. To clarify what are the expected features available in a particular editor, please view the table below and compare it with the level of support for the editor in question. Not every editor currently supports all the features of its specified level, but we intend to bring all editors to full compliance with their expected feature set.

# Well-supported Editors

Level 3 editors are CSS, HTML, JS, Python, Ruby, PHP, and ERB. The editors below fall into level 2 and level 3 support groups. In general, these editors will have the most advanced features.
