FAQ
What file formats are supported?
Any standard PostgreSQL schema file — plain SQL DDL scripts or output from pg_dump --schema-only. Just paste or upload the file.
Can I compare schemas from different Postgres versions?
Yes. The parser handles syntax from Postgres 12 through 16, so cross-version comparisons work without any extra configuration.
How do I export the diff report?
After the diff is generated you can download it as a self-contained HTML file or a PDF — great for sharing with your team or attaching to a PR.
