Radicle: Local-First Code Collaboration
<p>Git came and changed the landscape of collaborating on code in a decentralised and efficient manner – once you get to grips with the command-line, of course. GitHub capitalised on the fact that the social element of collaboration was missing from Git, while social platforms were emerging left, right, and centre. Our beloved, decentralised tool succumbed to the powers of centralisation...</p>
<p>To empower Git users once more, the Radicle protocol (heartwood<a href="https://app.radicle.xyz/nodes/seed.radicle.xyz/rad:z3gqcJUoA1n9HaHKufZs5FCSGazv5">^1</a>) is a decentralised forge to allow people to collaborate in a sovereign and local-first manner. It introduces the ability to define social artifacts that live alongside your code and are present right-there on your disk.</p>
<p>Let's dive in to see how we did this, and how you can get involved in shaping a better future for collaborating together. </p>

<p>Welcome to the "Local First, sync engines and CRDTs devroom", first edition this year at FOSDEM'26. We are excited to propose you a full day of amazing talks ranging from CRDT libraries and frameworks, to local first projects using them, and including academic research, UX design, sync protocols and engines.</p> <p>We believe Local First software is the future of app development. But what is Local First software? In this short introduction we will touch upon the general concepts and describe ...

<p>CRDTs are an exciting primitive for distributed state. In local-first apps, synced CRDTs can be framed as a natural extension to reactive local state, allowing developers to build eventually consistent multi-device and multi-user apps, with business logic living completely on the client, only requiring generic syncing infrastructure.</p> <p>A key feature that traditional backends solve remains a challenge, though: how do permissions work in this world? In addition to being a ...

<p>Yjs is one of the oldest and most widely used libraries that enhance web editors by allowing multiple users collaborate over documents in real time, also without requiring continuous network connection. Evernote and Jupyter Notebooks are among many of its prominent users.</p> <p>During this presentation we'll address some of the common pitfalls that new developers may encounter when working with Yjs library, what architectural foundations are causing them to happen and what can we do to ...

<p><a href="https://github.com/makeplane/plane">Plane</a> is an open source project management tool used by thousands of teams. A year ago, we shipped Wiki — a collaborative documentation system built on Yjs with real-time editing, offline support, and version history.</p> <p>Yjs is remarkable. Kevin Jahns and the community have built something incredible — real-time sync, conflict resolution, offline editing, all handled elegantly. But integrating a powerful library is just the start. This ...

<p>Automerge is a mature library for building local first applications by enabling version control for structured data. The strategy is to capture all edits to data at a very fine grain (e.g. per keystroke when editing text) and then present a good API for managing concurrently edited versions of this data. </p> <p>The version control approach to collaboration makes working concurrently feasible and makes servers fungible - it increases user autonomy, but it introduces problems as you can't rely ...

<p>NextGraph is a protocol, a framework, and a platform that supports easy development of Local-First, decentralized, secure and private apps.</p> <p>By combining the best of the local first world (Yjs, Automerge CRDT libraries), a graph database, DID (decentralized identifiers) for users and documents, and end-to-end encryption plus encryption at rest, we provide an SDK that offers all the requirements of portability, interoperability and security needed today for building a true alternative to ...

<p>Building fast, resilient, and collaborative applications increasingly demands more than reactive UI frameworks and client-side state management. The next generation brings reactivity to the data layer itself—letting applications stay in sync with the backend automatically through a sync-engine architecture.</p> <p>This talk explores how <a href="https://tanstack.com/db">TanStack DB</a> provides a practical path toward such architectures without requiring a rewrite or commitment to a ...
