Our take
Pick Convex if typeScript app teams who will stay on Free $0 (1M function calls, 0.5 GB database, 1–6 developers) while they ship a prototype, then buy Professional at $25 per developer / month when they need 25M calls, log streaming, and daily backups. Pick PowerSync if mobile / local-first teams who will stay on Cloud Free at $0 (2 GB synced, 50 clients) while they create a first Project, then buy Pro at $49/month
