How can I browse Cydia repos without an iOS device? My understanding is that Cydia is a mechanism for accessing third-party software repos on iOS. (The equivalent of Homebrew for macOS.)

However, I am having trouble locating the "default" Cydia repos, and browsing them to see what software is available. How can I do this without an iOS device?

For example, is there an equivalent of the https://f-droid.org (a similar tool + website for Android)?
Cydia is really a GUI front end for apt, the homebrew equivalent on iOS and many other Linux systems, so a Cydia repo is really an apt repo.

You can use CyDownload to view and download the packages(.debs) on your computer. 

Some popular repos:


BigBoss(http://apt.thebigboss.org/repofiles/cydia/)
Packix(https://repo.packix.com/)
Chariz(https://cydia.hbang.ws)
Coolstar/Electra(https://electrarepo64.coolstar.org/) (for iOS >= 11)
Saurik/Cydia(http://apt.saurik.com/) (for iOS &lt;= 10)
