Build Cloudless, Collaborative Software

DXOS provides developers with everything they need to build real-time, collaborative apps which run entirely on the client, and communicate peer-to-peer, without servers.

DXOS applications work offline, share state instantly when online, and leave end-users in control of their data and privacy.

A new breed of apps.


A fully local database provides an instant-on app experience, especially when combined with PWA or hybrid app architecture.

Real-time multiplayer

Conflict Free Replicated Datatypes at the heart of the platform enable multiple concurrent writers to operate on the same data without data loss or conflicts.


The database being client-side and peer-to-peer, there is no need for any server infrastructure, besides serving the application client itself.


All data is stored in an append-only CRDT allowing offline users to recover gracefully when they return online, reconciling their changes with the rest of the swarm.


Since data never travels to any servers, end-users enjoy total privacy by default. The database is isolated from any application using it, allowing users to credibly exit any application without losing data.


Multiple applications on the same device share the database instance, enabling deep, real-time interop between apps without transforming formats or dealing with APIs.
