Mystra checks the customer journey after every deploy

A browser-based monitor that signs up to an app, completes checkout, follows email verification, and checks whether paid access actually unlocks.

Landing page captured for the 2026-09-04 issue.

Field notes

Mystra is designed around post-deploy customer-path tests rather than simple homepage uptime checks. Its described runner creates a fresh account, handles welcome or magic-link email through a dedicated inbox, completes checkout, and verifies entitlement, with a deploy webhook or hourly schedule initiating the sequence. The page shows evidence artifacts including screenshots, HAR files, console logs, and email trails, and describes retry handling that labels a one-time failure as flaky rather than paging immediately.
