TALK

Consistency Without Coordination: Sync in Local-First Systems

Local-first software promises offline support, low latency, and user-owned data. Delivering that experience hinges on one hard problem: sync. This talk dives into the design of synchronization engines that power local-first systems. We’ll explore how data storage and end-user devices exchange and merge changes under unreliable networks. Techniques, such as Conflict-free Replicated Data Types (CRDTs), are the “secret sauce” to ensure that updates made on one device are automatically reconciled with changes made on others, even when they happen offline. Finally, we’ll ground these ideas in a case study on collaborative spreadsheets, analyzing how sync engines deal with high-frequency edits and complex data models. If you’re building or evaluating local-first systems, this session will give you a concrete mental model and the engineering insights to reason about sync.
