Mycelium SQL

A SQL client for MySQL servers that sit behind an ssh bastion. Targets are named in a config file, the tunnel is raised with your own ssh, and a connection is pinned rather than juggled — one editor, one results grid, one run log, a searchable history and a schema browser, all in the same window.

It is meant as the day-to-day replacement for MySQL Workbench on a Mac. The differences are the ones that bite daily rather than the ones on a feature list: a native window instead of a cross-platform one, the bastion hop treated as the normal case rather than as configuration, and every query you have run kept in one searchable history instead of scattered across tabs you are afraid to close.

It ships with no connection targets: a fresh install connects to nothing and names the file to create. Passwords live in the login Keychain and nowhere else. A Go core owns the connection, the tunnel and the history; a Swift/AppKit window sits on top of it.

It is free, and the packaged build is the last thing between this page and an installer. The download lands here as soon as it is signed.
