Schemasift
Profile recorded schema changes, weight affected rows and consumers, classify type and nullability drift, and preserve migration evidence.
Focused field tools
Use stable source, table, path, field, and version identifiers.
Compare physical type, logical meaning, units, precision, and coercion behavior.
Separate missing, unknown, inapplicable, redacted, and failed parsing states.
Watch new, removed, merged, or unexpectedly exploding values.
Inventory transformations, models, dashboards, exports, APIs, and scripts.
Plan rate, ordering, checkpoints, idempotency, verification, and restart.
Schemasift analyzes manually entered or imported schema evidence; it does not inspect live databases, prove data quality, or execute migrations. Validate source semantics, sampling, consumers, constraints, backfills, rollback, and production observability directly.
