How to build a local-first sync engine with CRDTs in a React app. Cover the architecture, key decisions, and performance results.
1/ We just shipped local-first sync and it changed everything. CRDTs + custom conflict resolution. 3x faster than cloud-only. Here is what we learned building it: 2/ The key insight: most writes are non-conflicting. We only need the full CRDT merge path for <5% of operations. That means we can keep the hot path simple. 3/ Architecture: Yjs for the CRDT layer, IndexedDB for local persistence, WebSocket for sync. The client is always authoritative. Server is just a relay. 4/ Performance results after 2 months in production: - P50 write latency: 2ms (was 180ms cloud-only) - Offline writes sync in <500ms on reconnect - Zero data loss across 12k daily active users 5/ If you're building anything collaborative, start local-first. The UX improvement is massive and CRDTs are finally mature enough for production.
Teams and solo developers use Content Engine to ship content faster.
“I used to spend 2 hours writing a blog post. Now I get a solid first draft in 30 seconds and spend 20 minutes editing. Content Engine paid for itself on day one.”

“The tweet thread output is surprisingly good. I generate 3-4 threads a week for our dev-rel team and the engagement has gone up 40% since we started using it.”

“We use Content Engine for all our README files and docs. The tone controls mean technical docs actually sound technical, not like marketing copy.”
