Puter

Puter is a browser-based desktop operating system that gives you a full personal computing environment without installing anything. It's built for people who want their files, apps, and tools accessible from any device through a web browser, with everything stored in the cloud.

The experience mirrors a traditional desktop: you get a windowed interface, a file manager, and a suite of built-in applications for common tasks. It's designed to work as a daily driver for productivity, creativity, and general use, all from a single URL.

Key capabilities include:

• Cloud file storage that's accessible from any browser session, with your files persisting across devices
• Built-in apps covering writing, editing, and other everyday tasks without needing third-party installs
• App hosting so developers can deploy and serve web applications directly within the Puter environment
• Authentication options including Google, Microsoft, and Apple sign-in alongside standard email/password login
• Two-factor authentication with recovery code support for account security

What sets Puter apart from simple cloud storage tools is the full desktop metaphor. It's not just a file sync service or a document editor; it's a complete environment where multiple apps run in parallel windows, much like a local OS.

Being open source means you can self-host the entire platform, which matters for teams or individuals who want control over their data rather than relying on a third-party cloud. The codebase is available for inspection, modification, and private deployment.
