Outerbase Studio – Open-Source Browser Database GUI

TL;DR

TL;DR: Outerbase Studio is an open-source, browser-based database GUI that connects to SQLite-based databases (Turso/LibSQL, Cloudflare D1, rqlite), plus PostgreSQL and MySQL, with a query editor, data grid, and schema editor — no install needed.

What Is Outerbase Studio?

Outerbase Studio is a lightweight, browser-based GUI for managing SQL databases. Originally built around LibSQL and SQLite, it has expanded to support a broad range of databases:

• SQLite-based: Turso/LibSQL, local SQLite files, Cloudflare D1, rqlite, StarbaseDB, Val.town
• Beta: PostgreSQL, MySQL

You can try it directly in the browser at libsqlstudio.com, or self-host it via a Cloudflare Workers deployment. A desktop Electron wrapper is also available for Windows and macOS, enabling MySQL and PostgreSQL drivers that require a native runtime.

Setup Workflow

Option 1: Try in Browser (No Install)

Visit libsqlstudio.com and connect to a database. The playground mode ships with sample data so you can explore the interface without configuring anything.

Option 2: Self-Host on Cloudflare Workers

Deploy to Cloudflare →

1. Click the Deploy to Cloudflare button above.
2. Authorize with your Cloudflare account.
3. Set the DO_PERSIST environment variable to true if you want to persist data between sessions.
4. Deploy — Cloudflare handles the rest. No Docker or server config needed.

Option 3: Desktop App

Download the Electron desktop app from the releases page. The desktop version supports MySQL and PostgreSQL drivers not available in the browser build due to browser sandbox limitations.

Connecting to a Database

1. Open Connection Manager.
2. Add a new connection with your database URL and credentials.
3. Outerbase stores connections locally in the browser by default, or you can configure a server-side connection store to share across devices.

Feature Breakdown

Query Editor

The query editor supports auto-completion and function hint tooltips. Multiple queries can be executed simultaneously, with results displayed in separate tabs.

Data Editor

The data grid is optimized for large result sets, capable of rendering thousands of rows and columns. All changes are staged before committing — a preview step prevents accidental writes.

Schema Editor

Create, modify, and delete table columns through a UI without writing raw SQL. This is especially useful for rapid prototyping on SQLite-based databases.

Practical Evaluation Checklist

• [ ] Connects to a local SQLite file without configuration
• [ ] Connects to Turso/LibSQL using the provided libsql:// URL
• [ ] Executes a multi-statement query and displays results side by side
• [ ] Stages edits in the data grid and previews before commit
• [ ] Uses schema editor to add a column to an existing table
• [ ] Deploys to Cloudflare Workers via the one-click button
• [ ] Desktop app launches and connects to a PostgreSQL instance

Security Notes

• Connection strings are stored in the browser local storage by default (desktop app) or in a configurable server-side store.
• For production use, use read-only database credentials where possible — Outerbase does not ship with built-in row-level access control.
• The Cloudflare Workers deployment runs at the edge; ensure your database firewall allows Cloudflare IP ranges for managed databases like Turso.

FAQ

Q: Does it work with Cloudflare D1? A: Yes. Select the LibSQL/D1 connection type and enter your libsql:// or https:// D1 URL with your auth token.

Q: Can I use it with MySQL or PostgreSQL? A: Yes, both are supported in beta. The desktop Electron app is recommended for MySQL/PostgreSQL since the browser build lacks the native drivers.

Q: How does it compare to TablePlus or DBeaver? A: Outerbase Studio is fully browser-based with no desktop install required. It targets developers who want a lightweight, shareable SQL interface for SQLite-first stacks, particularly Turso, LibSQL, and D1. TablePlus and DBeaver offer deeper native driver support and offline capability.

Q: Is the source code available? A: Yes. Outerbase Studio is fully open source under AGPL-3.0. The desktop wrapper is also open source.

Conclusion

Outerbase Studio fills a gap between lightweight SQL playgrounds and full-featured database clients like TablePlus. Its browser-first design makes it trivial to share a database GUI with a team without asking anyone to install software. The Cloudflare Workers deployment option is particularly clean — one button and you have a self-hosted, edge-deployed SQL interface for your Turso or D1 database.

If you primarily work with SQLite-based databases (Turso, D1, rqlite) and want a shareable, no-install GUI, Outerbase Studio is worth a look.
