Where are Homebrew bottles stored online?

Question

From where are Homebrew bottles downloaded?

Homebrew Documentation: Bottles doesn't say.

I created a Github Homebrew/brew issue #672.

Answer 1

See the Homebrew README:

Our bottles (binary packages) are hosted by Bintray.

Bintray: Homebrew

Answer 2

As of May 2021, Bintray is no longre available and bottles are hosted at GitHub https://github.com/orgs/Homebrew/packages

History and recommended reading:

• There is an excellent 2019 background article describing how to Maintain your own Homebrew repository, with binary bottles, which explains the url pattern of the bottles hosted at Bintray. It's still valuable reading when dealing with older formulae and taps, even if Bintray isn't valid any more. The URL pattern was usually something along to https://dl.bintray.com/<user>/bottles-<tap>.

• In 2020, as of Release 2.5.2, uploading bottles to GitHub Releases became supported.

• In 2021, as of Release 3.1.0, GitHub Releases became the default location.
