Database Client

Connect to MySQL or PostgreSQL, run queries, and browse schemas — directly from your browser.

What is a Database Client?

A database client is the application you use to talk to a relational database — issue SQL queries, inspect schemas, browse tables, and analyze results. Desktop clients like TablePlus, DBeaver, and the psql or mysql CLI are powerful but require installation, configuration, and a managed credential store. A browser-based client trades some of that depth for portability: open a tab, paste connection details, and start querying — useful for quick reads on a colleague's laptop, an emergency check on a Chromebook, or any workflow where installing software isn't practical. This client supports MySQL and PostgreSQL over TLS, with a syntax-highlighted query editor, schema browser, and CSV export. Building queries that return JSON? Format them with the JSON Formatter. Need to manage cloud files alongside your database? Use the S3 File Editor.

Frequently asked questions

Where are my database credentials stored?
Credentials are encrypted in your browser's localStorage with a key derived from a passphrase you set. Connection details are passed through our server only to establish the TCP connection to your database — they are never logged, never persisted server-side, and the connection terminates as soon as your session ends.
