PowerSync

What it is for

PowerSync is a hosted Postgres-to-SQLite sync desk: you create a Project, and Free is $0/month (2 GB synced, 500 MB hosted, 50 peak clients, 2 instances, no card). Use it when the job is offline-first sync you start at $0, not when you need a $20 chat seat.

What makes it unique: the cover is the official PowerSync Create New Project dialog (My First Project, Development + Production US instances) from the dashboard still — not a pricing card. The dialog itself is ops of Projects. Free projects are deactivated after 1 week of inactivity.

Key features

• Projects — a sync app with Dev / Prod instances (Create still; docs). One app. Cover Development / Production US checkboxes are options of a Project, not extra desks. Free includes 2 Service instances.
• Sync rules / buckets — the subset of rows a client may download (docs). A rule, not a project. Bucket storage you bring on Team is ops of this.
• Source database — the Postgres / MongoDB / MySQL / SQL Server you connect (pricing 1 source database connection per instance). A source, not a rule. One connection per instance on Free.
• Client SQLite — the on-device DB the SDK keeps in sync (docs). A local store, not a cloud table. SDKs are install.
• Cloud / self-host — the managed Service vs the OSS binary you run (pricing Cloud / Self-hosting toggle; GitHub). A control plane, not a project. Self-host is $0 software + your infra. Cloud Free deactivates after 1 week idle.

Private Endpoints, SOC 2, and HIPAA print on Team. Version locking and uptime SLA are Team, not a sixth desk.

Who it's for

Best fit: 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 when they need 30 GB synced and no idle deactivation.

Confirm checkout; taxes follow your location.

Limitations / costs

• Free Cloud sleeps after 1 week idle. A weekend side project can deactivate.
• 50 peak clients and 2 GB synced are soft-looking limits on a $0 card — Pro is the production path.
• One source DB per instance on Free. A second database is another instance (Free cap: 2).
• A sync desk, not a hosted Postgres. For serverless Postgres see Neon. For edge SQLite see nothing in-catalog that replaces this sync loop.

Alternatives

• Neon — hosted Postgres when you need a database, not a client SQLite replica.
• Convex — realtime backend when the client should talk to a hosted document/function layer, not sync buckets.
• Firebase / self-host — Appwrite when you want a BaaS bundle (auth + DB) instead of PowerSync’s sync engine.
