At we focus on simplicity, speed, and, most importantly, reliability. If you're using as your primary or secondary IDE we want you to be confident that the time you invest working on your code will never go to waste.

Building on our autosave feature, the underlying infrastructure -- every repl has its own filesystem now -- we've built an automatic revision system that keeps every revision of code you've ever written stored. The trouble was, as many of you pointed out, there was no easy way to manage it. That's why today we're excited to introduce Repl History, a page where you can view files, drill down to view old revisions by day or by change, diff them against latest, and finally easily restore them.

Here is a quick gif walkthrough:


You can access this from your repls dashboard or from individual repls by clicking on the saved/history button.
