AltDeploy is a desktop tool for sideloading and installing iOS apps on iPhone, iPad, and iPod touch. It makes it possible to install any third-party app on your iOS device using a .IPA file.

AltDeploy is one of the best alternatives to Cydia Impactor. It can install apps quickly without any hassle and offers a couple of additional features, such as saving your Apple ID so that you don't have to re-enter it every time you wish to install an app with AltDeploy.

AltDeploy does have a couple of limitations, such as:

• It currently supports macOS and doesn't work on Windows or Linux.
• You can only have 3 apps installed at a time.
• Apps expire every 7 days and have to be re-installed with AltDeploy once expired.
