About

A workspace that stays yours.

CouShell is a collaborative workspace for teams who want to own their work — notes, boards, calendars and more, in real time, online or off.

Local-first, always

Your work is saved on your device first. The network is an optimization, never a requirement.

Built for together

Real-time isn’t a feature bolted on — every node, view and cursor is collaborative by default.

No lock-in

CouShell runs on the open Abracadabra engine. Your data stays portable and yours.

A b r a c a d a b r a

CouShell is built on Abracadabra — an open, high-performance collaboration engine. That foundation is why your data is portable, why it works offline, and why real-time just works. CouShell is the polished workspace on top.
