Open-source apps that replace Google Docs, Microsoft Word and more

ONLYOFFICE Docs is an office suite for documents, spreadsheets, presentations and forms that several people can edit together, and it opens Microsoft Office files well. You run it on your own server, or use ONLYOFFICE's separate free desktop app.

Collabora Online is office software you run on your own server so people can write and edit documents together in a web browser. It is for groups and organizations that want shared document editing on their own server.

LibreOffice Writer is a desktop word processor for writing and editing documents on your own computer. It is for people who want an office suite that runs locally and works with common document formats.

Etherpad is a real-time shared text editor where several people can write in the same document at once, and every change is recorded with its author. It is aimed at organisations, schools and self-hosters who want to run their own server.

CryptPad is a web-based document suite where files are encrypted in your browser before they are stored or shared, so the server cannot read them. It is for people who want to write, edit and share documents, sheets and presentations together with privacy.

Fix the list itself
A project or closed app missing from this list, or a mistake on it? These open a short form on GitHub, and a mod reviews it. To say what a project can't do, use What's missing.
About this page
Replaces fully means it does the main job of these apps; Replaces partly means it covers some of it.
Licenses: every project here uses an open-source license (what each one means). Open core means some parts are paid or under another license.
GitHub stars are shown for reference. They measure popularity, not whether it replaces anything.
Verified means r/TrueOpenSource mods checked it: open-source license, maintained, and it really does the job.
