Free tools

Tools for database backups, free and without an account. Each one runs in your browser, and none of them sends your data anywhere.

Backup file checker

Choose a pg_dump, mysqldump, mongodump or SQLite file to see its format and versions, whether it was cut short, what the restore target needs, and the command that restores it.

pg_dump command builder

Build a pg_dump command with compression, parallel jobs, age encryption and S3, and get the restore command that loads its output. Each format was tested by restoring it on PostgreSQL 18.

Attestation verifier

Check a surface's drill records as an auditor would: the hash chain from genesis and the Ed25519 signature on each record, in the browser, with nothing sent anywhere.

Object Lock cost calculator

See how many locked backups you hold at once and what they cost on S3, Backblaze B2 or Wasabi, and what daily, weekly and monthly tiers save.
