Frequently asked questions

Yes. Every download starts with 14 days of Pro, and when the trial ends the app becomes the free tier rather than expiring. On the free tier you can use Quick compare to compare any two databases, pg_dump files or migration folders across all 40+ object types, generate a dependency-ordered deployment script, and deploy it. Download it here.

Saved schema and data projects you can re-run anytime, comparison history and drift timelines, pipelines, the pgc command-line interface for CI and automation, reports and exports, parallel connections, include/exclude object rules, and pre- and post-deploy scripts. Quick compare, scripting and deploying stay free.

Quick compare is how the free tier compares schemas. Choose two databases, pg_dump files or migration folders, run the comparison, then generate and deploy the script from the result. The result isn't saved — once you leave it, it's gone. To keep a comparison and re-run it later, create a project; projects are part of Pro. Projects you created during your trial stay readable.

PostgresCompare supports PostgreSQL version 9.2 and later, through the latest PostgreSQL 18. We regularly update to support new PostgreSQL releases.

All comparisons happen locally on your machine. Your database credentials and data never leave your network. PostgresCompare connects directly to your PostgreSQL databases and processes everything locally.

Sometimes (after the app updates for example) the PostgresCompare background process does not restart successfully which can lead to the UI spinning and failing to load projects.

Fix the issue by finding the process "PostgresCompareWebApi" and killing it, then restart the PostgresCompare app. If the problem persists try restarting your machine.

PostgresCompare relies on the operating system to tell it where to store your data. Sometimes this can change leading to a new database file being created.

To recover your data you should:

1. Search your machine for the file "postgrescompare_7.db". There should be 2 instances of a file with that name. Note which file is the older one, it probably also has a larger file size.
2. Copy the old postgrescompare_7.db into the new location, overwriting the db file there.
3. Restart PostgresCompare
