James Cowling (convex) - How to Design a Sync-First Database

Before we founded Convex we promised ourselves we'd never build a database again. Then we realized that we couldn't achieve our dream of full end-to-end sync without building it natively into the db. I'll talk about why I think end-to-end sync is the holy grail app development primitive and how we designed our query language, sync protocol, and database itself to support this primitive.

Software UX, DX, and AX are all being redefined and reinvented as we speak. The next generation of products are being built on sync engines and local-first architectures, enabling realtime collaboration between humans and agents.

Learn from developers at the world's leading startups on how they use these technologies. Find out what you and your team need to know in building category-defining products.
