Everything (Puter)

The Everything Project is an effort by the team behind Puter, the open-source "internet OS", to rebuild common proprietary software from scratch as free, MIT-licensed web apps. Everything lives in one GitHub monorepo, with each app in its own folder under src/.

What's in it

As of October 2026 the README lists about 50 apps in nine groups:

• Office: Spreadsheet, Documents, Presentation, Whiteboard, PDF, Notes and Records (alternatives to Excel, Word, PowerPoint, Miro, Acrobat, OneNote and Airtable).
• Collaboration: Meetings, Teamchat, Email, Contacts, Calendar and Signatures (Zoom, Slack, Gmail, DocuSign).
• Creative tools: Photo, Video, Vector, Audio, Music and 3D studios (Photoshop, Premiere, Illustrator, Audition, FL Studio, Maya).
• Engineering: 2D CAD with DXF files, parametric modelling, circuit design and building design (AutoCAD, SolidWorks, Altium, Revit).
• Productivity, finance and business: tasks, projects, wiki, time tracking, surveys, accounting, invoicing, expenses, cap table, CRM, help desk, point of sale, inventory, hiring, shifts and more.
• Developer tools and games: an API client (a Postman alternative), chess, checkers, solitaire, sudoku and backgammon.

How to use it

Most apps have a hosted demo on a puter.com subdomain, such as Spreadsheet, Documents, CAD or Chess. Apps such as Spreadsheet open without an account; you sign in to Puter only when you want to save files to your Puter cloud. Developers can clone the repo and run any app locally with Node.js 22.12+ (npm install, npm run dev).

Who it's for

Anyone looking for free browser alternatives to paid SaaS, and developers who want readable, permissively licensed app code to study, fork or self-host.

Caveats

The repository was created in October 2026 and is moving fast. Apps vary in maturity, and a few still have no live demo, only source code. Don't expect feature parity with the products they replace yet.

License and related

MIT, except where a sub-project says otherwise; bundled third-party libraries keep their own licenses. For another open-source take on one of these categories, see Cal.com, a Calendly alternative.
