17 snips
Sep 2, 2025 In this insightful discussion, Brooklyn Zelenka, a distributed systems researcher and the brains behind the Vancouver Functional Programming Meetup, teams up with Julian Wood, an AWS Serverless Developer Advocate. They dive into local-first computing, a revolutionary approach that emphasizes running apps primarily on users' devices. The benefits? Reduced latency, enhanced privacy, and offline capabilities. They explore its potential for democratizing app development and contrast it with traditional blockchain functions, all while addressing security challenges and collaborative development.

Episode notes
Compute On The Device To Cut Latency
- Local-first shifts computation to user devices to cut latency and survive disconnection.
- It reduces reliance on always-on central servers and changes application economics and resilience.
Ship A Working Local Mock First
- Build apps locally with mock data and mock external calls before deploying remote services.
- Treat external API responses as owned data once recorded so the app can operate mostly offline.
Every Device As A Source Of Truth
- Local-first treats every device as a source of truth and uses mergeable data structures to reconcile changes.
- CRDTs and Git-like merging let replicas diverge offline and automatically stitch back together later.
