Declarative schema management for Snowflake and Databricks — never hand-write a migration again. A safety classifier refuses data-loss operations by default, on every change.
Five things that set this apart from a generic schema-diff tool.
Every change is UNRECOVERABLE / DESTRUCTIVE / EXPENSIVE / WARNING. Data-loss operations refuse by default — you opt in explicitly.
Knows dropping a stream resets its cursor, that CREATE OR REPLACE rewrites data, that pipeline objects carry runtime state.
Project ↔ pac ↔ live, in any combination. Offline builds let you review a diff without target credentials.
Partial-failure rollback via reverse-SQL synthesis. On Snowflake, zero-copy clone snapshots make it instant.
Your data never leaves your account. No phone-home. Air-gapped friendly, works entirely offline for the free tier.
Real product UI — schema compare, safe deploy, and account extract.
SDT and DDT priced identically. Free tier works forever, offline, no account needed. 30-day free trial on Pro/Team.
