Latest release
What’s New
- Set execution context (@inject-into) for your script. Zoo Runtime API is now only available when running in Content Script context. - Script injection engine has been rebuilt from scratch. It’s much faster and much less error prone, and runs on newer iOS versions. - Tweaked design to adopt Liquid Glass on iOS 26. - Popup now shows script injection status if the script failed. Zoo now supports iOS 17 and later. Thank you for your patience and support.
