Safari extension TestFlight rehearsal from packaged ZIP

Package the extension for testing and share TestFlight links before the public App Store push, so the enable flow breaks in rehearsal instead of on the listing page.

Why this can grow a startup

Safari extensions often fail in the boring part between download and first use. The host app installs, the extension still needs to be enabled, and the team only learns where the instructions are weak after strangers hit the page. Apple now supports packaging a web extension from a ZIP file in App Store Connect, then sharing TestFlight links before distribution. That is useful because it lets the team rehearse the exact install and enable path with outsiders before the public shelf starts collecting confused reviews. A smoother TestFlight path usually predicts a calmer App Store launch.

Company example

When not to use it

Use the first one to three screenshots to show setup and first use, because Apple can surface those images directly in search results before the buyer ever opens the listing.
