01 · sovereign by design
Live collaboration on your own infrastructure.
Self-host on Kubernetes, or run on the docs cloud. Your data lives where you say it does — every commit, every cursor, every byte.
Papper · next-gen platform
Documents that commit to history.
Sovereign cloud, real-time co-writing, and durable versioning. Built for teams that treat their writing the way engineers treat their code.
02 · every save is a commit
History you can read.
Authored, timestamped, diff-able, restorable. Walk the revisions, blame a paragraph, restore a sentence from last week.
03 · together, in real time
Cursors carry names.
Presence is a hairline, not a parade. Offline edits merge on reconnect — the CRDT handles the arithmetic of agreement.
