See exactly what changed: schema diff and sync
Changing a schema is easy. Knowing exactly what your change will do before you run it is the hard part. SnoutData's schema diff puts the two states side by side and writes the migration for you to read first.
Pick two schemas and SnoutData lays them out in a two-pane diff: what is added, what is dropped, what changed type, what moved. The differences are the point, so they are what the view emphasizes, instead of making you scan two full schemas and spot the deltas yourself.
A migration you can read
From the diff, SnoutData generates the migration SQL as a preview: the exact statements that would take the left side to the right side. You read it, edit it if you want, and only then run it. No black box, no "trust me," just the statements in front of you before anything touches the database.
