About Sequel Ace

Sequel Ace is a Mac database management application for working with MySQL and MariaDB databases. It is described as the sequel to the long-standing macOS tool Sequel Pro and is written in Objective-C, with documentation on its own website.

It runs on Intel and Apple Silicon Macs and is available from the Mac App Store, through the mas command-line tool, and via an unofficial community Homebrew cask. Older releases are provided for older versions of macOS and MySQL, but the maintainers state that no support is given for them. The README also describes a built-in Model Context Protocol server that lets AI agents query databases using the connections already saved in Sequel Ace. It is disabled until you enable it, accepts only local connections and is read-only.

Development is supported by sponsorships through Open Collective and GitHub Sponsors. The repository lists its licence as other, so check the project for its exact terms.
