Open-source agent by Comma (open source)

Comma review

Published · Updated

Comma is a free, open-source (AGPL) agent that carries tasks through to the end in your apps and files, using its own cloud computer, your Mac or a browser. You reach it on the web, Mac, Windows and Android, or by Signal and Telegram, and you can self-host it with Docker.

Rank 7 of 22 personal agents

7.3/10

Is Comma worth it?

It depends on what you need it to do. Comma is a personal agent. Price as of November 2026: free. It's worth it if you want an open-source agent with ready-made apps that you can self-host later. The main catch: leans toward work tasks. Meta Muse is the better choice if you want the most capable free personal agent and you're comfortable giving Meta access to your accounts.

Our verdict

Comma is the easiest open-source agent to try: there's a hosted free tier and apps, not just a terminal, and you can self-host when you want full control. It leans toward work tasks, and heavier use on its Pro plan costs $80 a month.

Choose Comma if you want an open-source agent with ready-made apps that you can self-host later.
