Zero-Downtime Schema

Safe schema migrations. Never lock a table again.

Automatic non-blocking index generation (create index concurrently), shadow table validation, and instant rollback safety.

Isolated DB Clones

A clean DB for every Pull Request. Zero crosstalk.

Automatically spin up dedicated preview environments on every push. Run end-to-end integration tests in parallel, then auto-destroy on merge.

Delta Storage

Pay for data diffs, not duplicate disk space.

Block-level pointer mapping means new database branches consume 0 MB until mutated. Store GBs of test deltas without paying extra for storage.
