Is My Migration Safe?

Editorial interest 82/100 Selection signal · not a rating of the site

A browser-based PostgreSQL migration checker that parses SQL locally and flags potentially risky schema changes.

Landing page captured for the 2026-08-25 issue.

Field notes

The tool models migration review around both SQL text and the size of the affected table, offering three row-count bands before checking a statement. Its browser worker downloads and compiles libpg_query as WebAssembly, while the interface separates parser output, parse-tree inspection, and rule-engine results. Included examples cover a default column, a concurrent index, and staged foreign-key validation, giving the workflow more specificity than a generic SQL editor.
