Key takeaways for Onyx - Dark Mode
Where is it heading?
The Safari extension market is increasingly dominated by tools that offer frequent updates to match browser engine changes. Onyx remains in a stable position, but its lack of revenue generation creates a long-term risk that it will fall behind native browser capabilities.
- The maintenance-only update cadence indicates the app is currently in a stable state rather than an active growth phase.
- Lack of monetization limits the ability to respond to Safari engine updates, creating long-term technical risk for the extension.
The SWOT
- Per-site settings allow granular control over dark mode rendering
- iCloud sync increases switching costs by maintaining user preferences
- Introduce a premium tier to fund a more aggressive update schedule
Next best moves
Audit Safari engine compatibility because the maintenance-only cadence risks rendering breakage → maintain user trust

The lack of monetization is a strategic weakness, not a user-friendly advantage…
Read the full takeBottom line
Onyx serves as a stable utility for power users, but its maintenance-only cadence limits its ability to compete with browser-native features. Transitioning to a sustainable monetization model would unlock the resources needed to defend its position against Safari engine updates.
