Safe-not-safe checks Postgres migrations with a browser-based parser

safenotsafe.dev Editor score 6/10

The tool uses libpg_query 17 compiled to WebAssembly in a browser worker, with a rule engine and no telemetry. It may help teams catch risky migration patterns, though the excerpt does not describe the rules or their coverage.

What: safe-not-safe is a browser-based tool for checking PostgreSQL migrations.
How: It downloads and compiles the libpg_query WASM parser in a browser worker to parse migration SQL.
Why it matters: Browser-side parsing gives engineers a way to inspect migrations and flag problems without relying on a remote parser.

Migration SQL is parsed in the browser and passed to the rule engine for checking. Sketched from the article's own text.
