The best open source alternative to Google Docs is Macro Docs. If that doesn't suit you, we've compiled a ranked list of other open source Google Docs alternatives to help you find a suitable replacement. Other interesting open source alternatives to Google Docs are: Docs, CryptPad, LibreOffice, and Collabora Online.
Google Docs alternatives are mainly Document Editors Tools but may also be Collaborative Workspaces or Collaborative Notes & Wikis. Browse these if you want a narrower list of alternatives or looking for a specific functionality of Google Docs.
Collaborative markdown documents with real-time CRDT editing, AI agent cursors, mention linking, and built-in properties tied to your tasks, channels, and email.

Macro is a markdown-native document editor built to live inside a broader workspace, not alongside one. Every doc connects directly to tasks, email, channels, and AI agents through @mentions that render as live inline pills. What sets Macro apart from tools like Notion or Google Docs is the agent layer. AI agents can edit documents alongside you with a live cursor, not just suggest a diff.
Key capabilities include:
The editing foundation is built on CRDTs (Conflict-free Replicated Data Types), which means multiple people can type on the same line simultaneously without conflicts. Edits apply locally first and reconcile in the background, so the experience stays fast even offline. The backend is written in Rust with a SolidJS frontend, and each document runs as its own Durable Object in the cloud, keeping latency low. Macro is licensed under AGPLv3.
Macro is aimed at teams who want the writing experience of something like Outline or Logseq but need their docs to stay in sync with everything else happening at work. Things can be @mentioned directly in a doc and given context from tasks, channels, or email threads in the same workspace.
