 Firebase and Supabase are Backend-as-a-Service platforms. They give you a database with an API layer on top, but your application logic still runs elsewhere (cloud functions, edge functions, or your own server). Complex business logic is awkward to express as database triggers or serverless functions.

 - [Incremental Migrations](/docs/databases/incremental-migrations): SpacetimeDB does not provide built-in support for general schema-modifying migrations. It does, however, allow adding new tables, and changing reducers' definitions in arbitrary ways. It's possible to run general migrations using an external tool, but this is tedious, necessitates downtime, and imposes the requirement that you update all your clients at the same time as publishing your new module version.
 - [Transactions and Atomicity](/docs/databases/transactions-atomicity): SpacetimeDB provides strong transactional guarantees for all database operations. Every reducer runs inside a database transaction, ensuring your data remains consistent and reliable even under concurrent load.
