Edit your app's code in the browser
Open your app's code with a file tree, tabs and search, save a change as a new version, and try it on a preview before it goes live.

A quick fix no longer needs your laptop.
What's new
Code on an app's page opens its newest version: a file tree, up to 12 files in tabs, search by name or inside files, and colours for PHP, JavaScript, Python and more. Older versions open to read.
A terminal under the code, when you ask for it.
Save makes a new version with a short message, like "Fix the checkout total". Nothing goes live until you choose Deploy. If a newer version came in since you opened a file, we name it before saving.
Apps from GitHub: each save also opens a pull request on your repository once you allow it. Until then, the version is saved here and the editor says the change isn't in GitHub yet.
Preview any version at its own address before it goes live: for 1 hour, 4 hours or a day, with empty databases or a copy of staging's, locked with a password unless you open it. It stops by itself, and its price shows before it starts.
