Hey Product Hunt I built DBA Bridge because I broke production. I spent weeks migrating an Oracle database to Postgres using cloud DMS. The migration "succeeded" — 100% rows copied, with errors reported. Then I connected the app. Nothing worked. Stored procedures had silently failed. Oracle DATE columns had lost their time component. Foreign keys had re-enabled in the wrong order. There was no report, no explanation of what went wrong, no way to know what to fix. Just a 40MB log file and a broken deadline. I looked for a tool that would have told me all of this BEFORE I touched production. It didn't exist. So I built it. DBA Bridge is a free, open source desktop app. You connect it to your source database (read-only), and it produces a full audit report: - Which stored procedures are clean, which need rewriting, which have no equivalent in Postgres - Every column with a risky data type conversion - The correct foreign key migration order - Overall risk score: Low / Medium / High / Critical Then it rewrites your stored procedures side-by-side using local AI (Ollama — your code never leaves your machine). You review and approve every suggestion. After migration, it validates everything — row counts, constraints, queries — and gives you a green/amber/red report per table. Currently supporting Oracle → PostgreSQL and SQL Server → Supabase. MySQL and MongoDB coming soon. Would love to hear from anyone who has been through a painful migration — what broke? What do you wish you'd known beforehand?
