About Macro

Macro is an all-in-one workspace for teams that brings messaging, mail, documents, tasks, AI agents, calls and customer records into a single quick interface. Everything in the workspace can be linked with @ mentions and searched, so people and agents do not have to hop between separate tools to find context.

The project grew from its founders' wish for a single operating system for their startup, after using Slack, Linear, Notion, HubSpot and Superhuman, which do not work together as one system. A shared team-level memory ties the pieces together. Repository topics reference Slack, Notion and Linear as comparison points, plus MCP and agent support. The code base is written in Rust and TypeScript.

Macro is licensed under AGPL-3.0 and offers a hosted sign-up, with documentation, a demo booking and a feature request channel linked in the README. It suits startups and small teams that want to replace a stack of separate collaboration tools.
