Sources (also called repositories or repos) are URLs that contain a JSON file listing available apps. When you add a source to AltStore or SideStore, the apps from that source appear in your Browse tab.
Think of sources like app stores within AltStore - each source has its own collection of apps maintained by different developers or communities.
Source Types
- Official - Verified by AltStore/SideStore teams
- Developer - Maintained by original app developers
- Community - Trusted community-maintained collections
- Unverified - Use with caution
How to Add Sources
Adding to AltStore
- Open AltStore - Launch AltStore on your iOS device.
- Go to Browse - Tap the "Browse" tab at the bottom.
- Open Sources - Tap "Sources" in the top left corner.
- Add Source - Tap the "+" button and paste the source URL.
Adding to SideStore
The process is similar - go to Browse → Sources → tap "+" and enter the URL.
Quick Add: Many sources have "Add to AltStore" buttons on their websites that auto-add the source.

Before Adding a Source

- Check update frequency - Active sources are regularly updated
Red Flags to Avoid

- Unrealistic claims (e.g., "TrollStore for iOS 18")
- Sources asking for your Apple ID
- Apps with unusually large file sizes
