Inspect is a network utility for iOS that allows users to view and debug TLS certificate chains, trust status, and security signals.
The App DNA
What makes this app unique?
Users hire Inspect to verify the integrity of HTTPS connections and identify potential interception products that standard browser security indicators hide.
For Security researchers, web developers, and privacy-conscious users who need to verify TLS certificate validity and network traffic on iOS and macOS.
What does it look like?
Key features
Passively captures TLS certificates and SNI from device traffic using a Rust forwarding core and packet tunnel extensions.
Inspects TLS certificates for the current webpage directly within the Safari browser interface.
Inspects URLs and page data shared from other apps via the iOS share sheet.
How much does it cost?
The app is distributed as a free utility with no visible IAP or subscription gates, relying on community support via GitHub Sponsors.
Velocity
Maintenance developmentperformanceUX improvementsShow more...
The app currently operates on a maintenance cadence, with the latest release occurring 126 days ago. Development is focused on technical stability, including certificate chain display improvements and database updates, rather than new feature expansion. Given the lack of updates in the last four months, the development momentum is currently stagnant.

Key takeaways for Inspect - View TLS certificate
Where is it heading?
The market for iOS security utilities is consolidating around tools that offer automated monitoring rather than manual inspection. Inspect remains a reliable manual tool, but without a shift toward automated alerting, it risks becoming a legacy utility as iOS security APIs evolve.
- The 18-week update cadence indicates the app is in maintenance mode, which limits its ability to respond to new iOS networking security protocols.
The SWOT
- Rust-based packet tunnel extension enables passive TLS capture, a capability standard browser tools cannot replicate.
- Safari and Action extension integration lowers the friction for ad-hoc certificate verification across the iOS environment.
- Enterprise-focused audit logs could transition the app from a hobbyist utility to a B2B security tool.
Next best moves
Ship automated certificate transparency log alerts because users require proactive security monitoring → increase daily utility value.
The counter-intuitive read
The app's maintenance-mode status is a feature for its target audience…
Read the full takeSince the last report: The app's competitive position is now framed as stagnant, with the analysis shifting focus toward the need for automated monitoring and enterprise features to remain relevant.
Bottom line
Inspect provides essential TLS debugging tools for technical users, but its maintenance-mode update cadence creates long-term reliability risks, so the PM should prioritize automated monitoring features to maintain relevance against more active security tools.
