About 49 IDE

We recommend self-hosting — it's free, your terminals and files never leave your machine, and setup is two commands. If you just want to try it first, the cloud-hosted version needs no install: 49agents.com

After downloading, macOS will block the app because it is not notarized. Run this once to allow it:

Then open 49Agents normally. It runs as a tray icon — look for it in your menu bar.

Updates are delivered in-app: click the tray icon and choose Check for Updates .

Infinite canvas — no tabs, no splits. Place panes anywhere on a zoomable surface

Any device — laptop, tablet, phone. Same workspace, same layout

BSL 1.1 — free for individuals and small teams. Converts to MIT on 2030-02-26.
