SideStore is an iOS app sideloading solution that installs and manages applications outside the official App Store using only a standard, free Apple ID. It enables untethered installation and background maintenance of sideloaded apps without requiring a connected computer or paid developer account, leveraging a local VPN tunnel to bypass device restrictions.
At its core, SideStore provides automatic certificate renewal to keep sideloaded apps valid beyond their seven-day development certificate lifetime. It intercepts network traffic through the VPN tunnel, emulates anisette authentication data on-device, and relays signing requests to a remote server — all without a tethered host. The system stores encrypted Apple ID credentials and session tokens in the iOS keychain, and manages provisioning profiles on-device as needed for app signing.
The tool also includes a persistent background daemon that automatically re-signs apps before their certificates expire, ensuring ongoing usability without manual intervention. Its on-device architecture handles packet interception, anisette generation, and proxy signing within a self-contained mobile utility.
