What are the best alternatives to Installous?

Since the closure of Hackulous and the Installous app, several alternatives have gained popularity for sideloading applications on iOS. For jailbroken devices, AppCake and vShare were the most prominent successors. For modern iOS versions, users typically rely on tools like AltStore or Sideloadly. These applications allow you to sign IPA files using your own Apple ID and install them onto your iPhone or iPad via a computer. These methods have largely replaced the older, less stable Cydia repositories which often featured dead links or malware.
