System Dependencies on Replit
We recently released some improvements to our Packages tool, and now we're extending that work to bring a new System Dependencies tool to Replit, powered by Nix! Replit has bet big on Nix, and we're not slowing down. It's now easier than ever to leverage Nix's power with a brand-new user interface for adding, removing, and searching system dependencies.
Tabs and Spaces - Smarter Indentation
When you're programming, indentation is something you shouldn't have to think about, as an IDE should handle most of the details nowadays. With Replit, you don't have to think about what happens when you press tab. We're releasing a suite of new indentation and whitespace related features that will make the code editing experience even better.
Sep 29 Incident Update: Read-Only Repls
On Sep 29, we had a period of about 2.5h from 14:00 to 16:30 (Pacific Time), in which an incomplete build was pushed to our infrastructure that handles storing Repl data. This caused Repls opened during that time window to become read-only or stop working. Any Repl not opened during that timeframe was not affected. We have addressed the root cause, recovered 98% of the affected Repls, and continue to work on recovering the remaining 2%. We understand that your data not being available is unacceptable for both you and your users. This post summarizes what happened and what we're doing to improve Replit so that this does not happen again.
Changes to Hosting on Replit
We remain committed to providing a powerful free development experience to anyone who wants to code. This post is only about the hosting experience, which we are migrating to our new Deployments product.

Replit Deployments: 3x Faster and Even More Features
In April, we released Replit Deployments, the fastest way to go from software idea to production. We rebuilt our application hosting infrastructure for production-grade applications thanks to your feedback. In this post, we’ll highlight upgrades, bug fixes, and improvements to Deployments since initial release in April.
Replit Storage: The Next Generation
Repls today allow 256+ GiB of storage space, up from a historical 1GiB limit. This post is about the infrastructure that enabled that change.
June 6, 2023, Single-Sign-On Security Vulnerability
Earlier today, we emailed users about a security vulnerability affecting parts of our single-sign-on functionality. While we’ve fixed the vulnerability and have found no evidence of any exploit, we are publishing this post out of transparency.

April 2 Potential GitHub Credentials Exposure
Yesterday, on April 2, 2023, Replit discovered a site vulnerability that may have exposed GitHub auth tokens for <0.01% of Replit users, stemming from use of the GitHub import feature. This could have permitted unauthorized read/write access to all the repositories of those users by default (users can choose to authorize just a subset of repositories).
