Cursor's Origin makes S3 the source of truth for Git pushes
Cursor built a Git service called Origin, on an engine named Continuity, that uploads each push to Amazon S3 as an immutable write-ahead log and the source of truth, with local repository copies acting as a warm cache. Engineer Vicent Martí says a push synchronizes with one local reference repository instead of a quorum of replicas, so ingest runs as fast as disk allows — the opposite scaling curve from GitHub's Spokes design, which slows as synchronized NVMe replicas are added. Origin is in beta on paid Cursor plans.

Why this matters
- → S3 becomes authoritative—Git pushes no longer need quorum consensus across replicas
- → Linear scaling with disk speed instead of adding synchronized NVMe replicas
- → Cursor's infrastructure trades distributed consensus for write-ahead log durability
