atomic.place is a local-first workspace for documents, tables, files, chat and apps. It works on your device and can sync through a self-hosted AtomicServer or the hosted service at atomic.place. The underlying Atomic Data specification is open. It comes in three propositions:

• Personal Data Store: your identity is a key, your data is encrypted on your own devices, and every edit is signed by you.
• All-in-One Workspace: documents, tables, chat, meetings, canvas, websites, AI and apps, with one permission model.
• Local-first Sync Engine: build apps on the same Loro CRDT store and sync protocol, with no backend of your own.

This repo includes:

• atomic.place, the workspace in the browser, on desktop and on mobile.
• AtomicServer, the self-hostable server for storage, search, sharing and sync.
• docs documentation / specification for Atomic Data (docs.atomicdata.dev).
• Atomic Data Browser, the React front-end for atomic.place.
• @tomic/lib JS NPM library.
• @tomic/react React NPM library.
• @tomic/svelte Svelte NPM library.
• atomic_lib Rust library.
• atomic-cli terminal client.
• flutter a Dart / Flutter client (with demo app AtomicCanvas)

Status: alpha. Breaking changes are expected until 1.0.

Funding

Atomic Data and AtomicServer have been supported by NLnet through the NGI Assure, NGI0 Entrust and NGI0 Commons funds, with financial support from the European Commission's Next Generation Internet programme, and through Eurostars. This is a large part of why the project is MIT licensed and has no proprietary core. Details and grant agreement numbers.

Licence and trademarks

The code is MIT licensed — fork it, modify it, sell it.

The Atomic names and logos are not covered by that grant; they are reserved. Trademark is what lets the code stay permissively licensed, so a fork can do anything except present itself as the official Atomic Server. See TRADEMARKS.md for the policy and brand/ for the artwork, which is the single source of truth for every icon across all the Atomic apps.
