outerbase/studio

Outerbase Studio is a database management tool that runs in your web browser. Instead of installing a separate desktop application, you open it in Chrome or Firefox and use it to view, edit, and query your databases through a graphical interface. It was originally built for SQLite-style databases and has since expanded its support. The databases it can connect to include SQLite local files, LibSQL and Turso (a hosted SQLite service), Cloudflare D1 (a database product from Cloudflare), rqlite, StarbaseDB, and Val.town. MySQL and PostgreSQL support is listed as beta with limited features at the time of the README. The interface provides four main areas. The query editor lets you write SQL and run it against your database, with auto-completion and hints to help as you type. You can run several queries at once and see each result separately. The data editor shows your table contents in a grid where you can make changes, stage them like a preview, and then commit them all at once. The schema editor lets you add, change, or remove table columns through point-and-click controls without writing SQL yourself. Finally, the connection manager stores your database connection details locally in the browser, or on a server if you want to share them across multiple devices. A desktop version exists as a download for Windows and Mac. It is a thin wrapper around the same web interface but adds support for MySQL and PostgreSQL drivers that cannot run inside a browser for technical reasons. The project can also be deployed to Cloudflare Workers if you want to host your own instance.
