Where teams use SchemaSage
Safe production migrations
SchemaSage simulates migrations against a shadow database, predicts lock duration, and recommends online strategies before you ship.

Before dropping a column, see every dashboard, model, and pipeline that depends on it. Refactor with confidence.
FAQ
Common questions
How does SchemaSage learn what tables mean?
It combines column names, foreign keys, sample data, query patterns, and your existing docs. You can also annotate tables manually, and SchemaSage learns from those edits.
Will SchemaSage execute migrations automatically?
Only when you tell it to. By default, SchemaSage generates the migration plan and rollback script for human review. Auto-apply is opt-in per environment.
Does it integrate with our ORM?
Yes. SchemaSage supports Prisma, Drizzle, SQLAlchemy, ActiveRecord, and TypeORM, and can emit migrations in their native formats.
