The tool is released as the best alternative solution for Esign iOS, supporting iOS 14-18.5 (and iOS 26 betas), with features including bulk signing, background processing, and dylib injection.
This guide covers everything from installation to advanced tips, backed by real-user feedback from X and Reddit.
What is KSign iOS? The Best Free Alternative to Esign for IPA Sideloading
KSign iOS is an open-source app, available for download at GitHub (GitHub: Nyasami/Ksign), It is designed for signing and installing IPA files directly on your device. Unlike traditional methods like Sideloadly (which requires a PC), KSign runs natively on iOS, utilizing your Apple Developer or free distribution certificates. It’s ideal for tech enthusiasts wanting Spotify Premium tweaks or Pokémon GO spoofers without revocations.
The Ksign has a redesigned and well-organized UI compared to the Esign iOS app; also, the Esign team has terminated their software updates for further Apple release. Additionally, Ksign offers anti-revoke tools and is easy to import Development certificates.

Method 02: Sideloadly (PC Needed)
Sideloadly is another IPA sideloading tool that works on both Windows and Mac. Sideloadly does not need Apple’s Developer or distribution certificate files to sign IPA files. You can use your Apple ID and password to create a temporary developer account. However, the limitation is that you can only sign 10 apps, and the Sigend iPA files are only valid for 7 days. After 7 days, you need to sign them again.
Step 01: Download the Sideloadly Latest setup and install it
Step 02: Open Sideloadly and import the Latest Ksign iOS IPA file
Step 03: Connect your iDevice to PC and tap the sign-in button. This may take some time
Step 04: Once you complete the installation of the Ksign iOS app, it will appear on your device’s Home screen.
Troubleshooting: If revoked, reset the cache in KSign’s “Reset” tab. Restart the device post-iOS update.
