BX Sandbox: AI with a Seatbelt

bxsandbox.app Visit website

Editorial interest 84/100 Selection signal · not a rating of the site

A macOS launcher that runs AI apps inside folder-level sandboxes, so they can see only the files you choose.

Landing page captured for the 2026-09-19 issue.

For: Mac users running AI coding and desktop apps
Worth noticing: Denied file accesses appear in a tree with the responsible program named beside each event.

Field notes

BX uses macOS sandboxing rather than a virtual machine or container, according to the homepage. Its launcher model combines selected folders with app-specific presets, while .bxignore files can be kept under version control. A protection tree distinguishes readable, writable, and hidden paths, and the site says rejected accesses are recorded with the responsible program named beside them.
