AltServerPatcher - sideload IPA from Windows

Cydia Impactor is not working for a few months and because of frequent certificate revokes installing apps using 3rd party App Stores is also a pain. Mac users can download AltDeploy tool to sign IPA files, and AltServerPatcher app for Windows can help you to sideload IPA without revokes.

What is AltServerPatcher?

AltServerPatcher is a utility that patches AltServer to install any IPA from a web URL. This is an effective replacement of Cydia Impactor for Windows. The application doesn't sign IPA files itself. It offers presets allowing you to sideload common jailbreaks, such as unc0ver, Phoenix, or h3lix.

AltServerPatcher is packed with links to IPA files containing unc0ver, Chimera, Electra, doubleh3lix, doubleh3lix + sockport2, h3lix, Phoenix, etasonJB, Home Depot (9.1-9.3.4), Home Depot (8.4.1), yalu102, yalu + mach_portal, yaluX + extra_recipe, ChimeraTV, ElectraTV, and backr00m.

Additionally, you can provide own link to IPA file that will be downloaded, signed, and sideloaded to your iOS devices using AltServer. Before patching, AltServerPatcher creates a backup of AltServer.exe that can be restored from the app itself. If something goes wrong simply reinstall AltServer.

This is not a perfect solution or typical Cydia Impactor alternative, but it works and you can sideload any IPA file to your device without revokes. Of course, the free Apple certificate has the same limitations you know from Impactor. The sideloaded apps will work only for 7 days.

AltServer allows you to install max 3 apps on your device. Apps that have been installed using non-developer Apple IDs (instead of $99/year Apple developer account) are only valid for 7 days, at which point they will no longer open. Every 7 days after signing, it's required to repeat the install process, however, you do not have to delete the apps. All settings and game saves will be available.
