Frequently asked questions

Is the web diff really free?

Yes. Paste two schemas, get the visual diff, full migration SQL, rollback script, and ORM export — no account, no limits, no catch.

What does Pro add?

Pro ($39 lifetime) adds exports (Markdown, PDF, JSON, SQL), saved diff history, shareable links, and access to all 80+ micro-tools including this calculator.

How does the GitHub Action help?

The SchemaLens GitHub Action runs on every PR, comments the schema diff, reports breaking changes, and archives a self-contained HTML report. It catches schema drift before it reaches production.

Do I need a credit card to try it?

No. The browser tool is free. The GitHub Action is free. Pro is a one-time purchase through Gumroad.
