Sync engine guides

What a sync engine is, when you need one, and how the options compare. For building with Strata Sync, read the documentation.

• What a sync engine is, and when you need one

  What a sync engine does, the two ways it resolves conflicts, and when you should not use one.

• Linear's sync engine, open-sourced

  Linear's sync engine architecture mapped, part by part, onto the Strata Sync modules that implement it.

• Adding a sync engine to Supabase

  Supabase Realtime is a live feed, not a sync engine. How to add one to a Supabase Postgres, and what it costs you.

• Convex vs Supabase

  Convex and Supabase compared on ownership, reactivity, leaving, and the offline gap neither one closes.

• Strata Sync vs Convex

  Convex and Strata Sync compared: a managed database against your own Postgres, and where the two designs agree.

• Strata Sync vs Zero

  Zero and Strata Sync compared: an extra process against routes in your own app, ZQL against model classes, and when Zero is the better pick.

• Sync engines compared: Strata Sync, Zero, Electric, Convex

  Strata Sync, Zero, ElectricSQL, Convex, InstantDB and PowerSync on the three questions that actually separate them.
