Independent open-source project

An open-source Slack alternative you run yourself

If your team wants channels, threads and search without per-seat fees or sending its conversations to a vendor, Forma Chat runs as one binary on a server you control.

How Forma compares with hosted, per-seat team chat

A fair summary of the trade-offs. Forma is younger and does less today; its advantage is ownership, cost and built-in standups.

Who it is for today

Small and mid-size teams who want their own chat server, open-source projects, agencies running chat for clients, and anyone who would rather not pay per seat for standups.

If you need mature mobile apps, enterprise compliance certifications or a large app marketplace today, a hosted product is the safer choice. Forma publishes exactly what works in its feature status.
