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.

- Record a baseline for: Target users who complete the tactic’s intended next action. Set a guardrail that would make you pause the test.
- Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
- Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
