Key takeaways for Tampermonkey
Where is it heading?
The market for browser-based script management is consolidating as native browser engines integrate these capabilities directly. Tampermonkey's current maintenance-mode cadence leaves it exposed to these native alternatives, and the recent stability regressions accelerate the risk of user migration.
- Frequent reports of database wipes post-update lead to user frustration, which directly threatens the app's long-term retention metrics.
- Interface flickering in the latest release prevents script management, causing a decline in active feature usage among power users.
The SWOT
- Cross-platform script synchronization enables persistent workflows
- One-time purchase model reduces long-term cost friction
- iCloud storage integration would ensure script persistence
- Granular profile management would allow context-specific script activation

Native browser-level script execution (available in Orion Browser but absent here) +1
Since the last report: The app has transitioned from a state of minor UI instability to critical data loss, evidenced by a drop in category rank from #5 to #16 and a surge in negative sentiment regarding database wipes.
Bottom line
Restoring dashboard stability is the critical path to retaining the power-user base, as the current data-loss issues negate the app's primary utility. Resolving these regressions will unlock the capacity to build cloud-based backups that defend against native browser-level script integration.
