What is it?

AtomicServer is a self-hostable server for storage, search, sharing and sync, written in Rust. It is the backend for atomic.place, a workspace that combines documents, tables, kanban and calendar views, chat, meetings, canvas, websites and custom apps under one permission model. Data is stored as linked data using the open Atomic Data specification, and every edit is recorded as a signed commit.

The repository also contains a React front-end, JavaScript, React and Svelte client libraries (@tomic/lib, @tomic/react, @tomic/svelte), a Rust library (atomic_lib), a terminal client (atomic-cli), and a Flutter client. The browser app works offline and syncs when reconnected. Full-text search runs on the same index on server and client, and the API supports JSON-AD, RDF, Turtle, N-Triples and JSON-LD.

The server ships as a single binary that includes the web app, search, database and automatic HTTPS. The project is in alpha, and breaking changes are expected until version 1.0.
