What this was, and why it stopped

Cleanflight - Blackbox Explorer was a packaged Chrome App: it shipped its own files and ran in a window of its own, rather than as part of a web page. Chrome Apps were a separate platform from extensions, and Google withdrew it — support ended on Windows, macOS and Linux in 2022 and on ChromeOS in early 2025.

What it ran: 1 background script of its own.

Unlike a hosted app there is no website underneath this one to fall back on. The app was the whole program, so when the platform went, nothing was left behind it.

Its listing was still in the store when we checked on 1 September 2026. Being listed and being usable are different things, and the store does not distinguish them.
