Databasus, formerly Postgresus, is a free, open-source backup tool you run yourself, usually as a Docker container with a web interface. It started as a friendly UI around pg_dump and now also covers MySQL, MariaDB and MongoDB. It's well made and popular, and it's listed in PostgreSQL's software catalog. If it fits your setup, it's a great choice, and it's free.
Details about Databasus are from its public README and documentation as of the date above. Check the project for current features.
The real difference: where it runs
- Databasus is a server application. You deploy it (Docker, or platforms like Coolify and Dokploy), open its web UI on port 4005, and it runs backups from that server. It suits teams with a Linux box or a homelab already running containers.
- PostgresBackup is a native Windows app with a background service. Install it from an 8 MB installer and it runs backups from your PC or Windows server, no Docker or web server needed.
Where Databasus is stronger
- Free and open source.
- Many storage destinations: S3-compatible storage, Google Drive, FTP/SFTP, NAS, and more.
- Notifications to Slack, Discord, Telegram, email and webhooks.
- Restore verification: it can restore a backup into a throwaway database on a schedule and report the result, so you find out a backup is broken before you need it.
- Encryption, team features with roles, and audit logs.
- More engines than PostgreSQL.
Where PostgresBackup is stronger
- No infrastructure. No Docker, no web server, no ports to expose. It's a Windows app with a service that starts at boot.
- Desktop workflows. One-step Clone between servers (say, production to your local database), and restores of any
.dumpor.sqlfile with a few clicks. - Backups land on the Windows machine you're sitting at or administering, which is often exactly where people want a copy.
- Hosted-PostgreSQL help. Built-in tips for Supabase and Neon connections, and current client tools included.

Which should you choose?
- Choose Databasus if you already run Docker on a server, want backups managed in one place for a team, need cloud destinations or chat notifications, or prefer open source.
- Choose PostgresBackup if you work on Windows and want backups (and clones and restores) handled from your own machine with nothing to deploy.
Both use standard pg_dump files for PostgreSQL, so your backups stay portable whichever you pick.
