All The World's A StageIf work is theater and every business a stage, use OpenAct to build, instead of buy, the apps that run your show.

Build vs. Buy

We propose you build, with agents. Use OpenAct to scaffold your suite of apps. It's open source and it is free to use.

Projects app included

Manage projects with Kanban, Gantt and calendar views, an AI agent and search. Use it as it is, or as a model for your own app.

An app directory

Add apps by name. Official apps for time tracking, contacts, events, support and more are under review.

A framework for your own apps

Sign-in, companies, roles, permissions, live updates, email, files and the app shell are ready. Your app adds only its own features.

Permissions per company

Apps declare what people can do. Company owners choose which roles can do it, and the framework checks every request.

Agents that know their limits

The Projects agent acts for a person and never does more than their role allows. Risky changes wait for approval.

What OpenAct gives you

Business apps need the same parts: sign-in, company accounts, roles, invitations, permissions, email and a page layout. OpenAct builds these parts once, in the framework. Each app uses them and does only its own job. A company turns on the apps it needs, and every app works with the same people and companies.

You get	Where it lives
