The Everything Project is a mono-repository of open-source web applications built from scratch as stand-ins for the commercial software most people pay for, such as spreadsheets, document editors, chat, video calls and mail. It is published by HeyPuter under the MIT license, written mostly in JavaScript, and aimed at two kinds of reader: anyone who wants a free browser app in place of a paid one, and developers who want a readable JavaScript codebase for a familiar app they can fork, host or extend.
What it does
The repository holds many separate applications in one tree, grouped by the README's own navigation: Office, Collaboration, Creative Tools, Engineering, Productivity, Finance, Business, Developer Tools and Games. Each row in the README's tables names the app, the proprietary product it is an alternative to, and links to a live demo and to the app's source folder.
Office is the group the saved README shows in detail. Spreadsheet is listed as an alternative to Microsoft Excel, Google Sheets and Apple Numbers, with a hosted demo at spreadsheet.puter.com and code in src/spreadsheet. Next to it the project lists a documents editor and a presentation tool against Word and PowerPoint, and separate apps standing in for Zoom, Slack and Gmail, each as its own application rather than one bundled suite.
Reach further than that, toward Photoshop and AutoCAD, is the project's own stated scope rather than a finished result. The README's opening line says the goal runs "From Office to Slack and Photoshop to AutoCAD", and the GitHub topics include adobe, photoshop, cad, office and spreadsheet. Read those as the authors' target list, and check the table for a demo link before assuming any one of them is done.
How it works
The install steps describe the architecture. You clone the mono-repository, change into one app's directory under src/, install that app's dependencies and start that app's own dev server. There is no single build for the whole collection: apps go up one at a time, which also means a broken or unfinished app does not block the rest.
The apps run in the browser, and the published demos sit on puter.com subdomains. The README notes that demo and source links come from project metadata where it exists, and that missing destinations point to a link-status note instead, so the table itself tells you which apps are only source today.
Getting started
Node.js 22.12 or newer is the only requirement the README names. The project does not list operating system, chip, memory or GPU requirements, and nothing in the material asks for an API key, a model, an account or a paid service. The code is MIT licensed and free to clone and run. What the material does not say is who pays for the hosted demos on puter.com or how long they stay online, so run your own copy of anything you depend on.
The build lives in the repository itself (github.com/HeyPuter/everything), not on a Releases page, and there are no installers or app-store builds mentioned:
git clone https://github.com/HeyPuter/everything.git
cd everything/src/[app-name]
npm install
npm run dev
Replace [app-name] with the folder from the README's Source link, for example spreadsheet.
When to use it / when not
The main catch is coverage: a few of the listed apps have no live demo and only source, so trying them means building and running them yourself rather than clicking a link. The second is age. The repository was created on 13 October 2026 and last pushed on 29 October 2026, with 5,149 stars and 594 forks at the time of writing. That is two weeks of public history, so the star count measures attention, not maturity, and the material lists no releases or version numbers.
One more gap worth knowing before you start: nothing in the README or the project's own description claims compatibility with existing .xlsx, .docx or .dwg files. Whether your current documents open is simply not answered by the material.
- Use it instead of Google Sheets or Office 365 when the job is small, the data is yours, and owning and hosting the code matters more than feature depth.
- Don't use it if a team depends on a paid suite today and needs a drop-in replacement with guaranteed file compatibility, because neither is promised here.
Taken on its own terms, this is worth attention from self-hosters who want browser apps they control, and from JavaScript developers looking for a plain, MIT-licensed implementation of an app shape they already understand. A spreadsheet, a documents editor, a presentation tool and the Zoom, Slack and Gmail replacements are listed as rebuilt and open source, which is already more than most "open alternative" projects ship. Treat the rest of the catalog as a roadmap, check each app's links first, and judge it again in a few months of commits.
