See exactly what changes

We compare your live database with your new SQL file and show you a clear, line-by-line summary before anything is applied. No guessing required.

SELECT table_name, column_name, data_type
FROM information_schema.columns
WHERE table_schema = 'public'
ORDER BY table_name, ordinal_position;
— comparing 24 tables · 187 columns · done in 94ms

Safe testing environment

Your migrations are first tested in a temporary, isolated space. We never touch your live data until you give the final approval.

Fail-safe rollbacks

Migrations run inside a single transaction. If even one step fails, the entire process is cancelled automatically, keeping your database perfectly intact.

BEGIN;
CREATE TABLE products (...);
ALTER TABLE users ADD COLUMN ...;
ALTER TABLE orders ALTER COLUMN ...;
COMMIT; -- all or nothing

Complete history logs

Keep track of every change. Whether a migration succeeds or fails, we log who did it, when it happened, and the exact SQL that was run.
