Open Source

Free. Open source. Apache 2.0.

Gridline is Apache 2.0 and developed openly. Contributions, issues, and feature requests are welcome.

Gridline stays free. No feature is ever behind a payment. Ko-fi is only for those who want to say thanks.

Questions? Answered.

Is Gridline really free for commercial use?

Yes. Gridline is Apache 2.0. You can use it for personal, commercial, or internal work without paying or signing up.

Which databases are supported?

PostgreSQL and SQLite are fully supported today (browsing, querying, editing, backups, and the visual tools). MySQL and Redis connections are in active development.

How is this different from TablePlus, Beekeeper Studio, or DB Pro?

No paywalled features, no tab or connection limits, and DB-to-DB sync without intermediate files. We also expose deeper PostgreSQL objects like sequences, enums, extensions, roles, and grants.

Do you store my database credentials?

No. Passwords live in your operating system keychain (macOS Keychain, Linux Secret Service, or Windows Credential Manager), never in Gridline's local SQLite database.

How do you make money?

Gridline is free and isn't built around a paywall. If it saves you time, you can buy a coffee at ko-fi.com/adrianbonpin. It's entirely optional and never gates a feature. Otherwise, issues, docs, and contributions all help.

Can I contribute or self-host?

Gridline is a desktop app, not a SaaS, so there's nothing to self-host. The repo is open for contributions: code, docs, translations, and issue reports are all welcome.
