About NetLens
Network inspector
NetLens is a network debugging app built for local and remote developer workflows.
Main features:
- Real-time network traffic monitoring
- HTTP/HTTPS request and response analysis
- Performance measurement and optimization
- Security analysis and vulnerability detection
- Custom filters and advanced request sorting
- Copy and share captured traffic summaries and cURL output
JavaScript console support helps you inspect live page logs, warnings, and runtime errors while testing web interactions on iOS.
NetLens is useful for API testing, request/response debugging, and finding performance bottlenecks in a focused workflow.
Privacy at a glance
Plain language, app by app.
NetLens reads traffic and debugging data for traffic that you explicitly monitor and stores the analysis locally for your workflow. It does not create a NetLens account, store credentials in a developer cloud, connect your private browsing history, or run a user analytics SDK in the app. NetLens is a general-audience app and is not directed to children. Brent Gaddis provides NetLens and is the data controller for the app information described here. The monitored privacy contact is gaddisapps@icloud.com.

FAQ
Common questions
Why am I not seeing any network requests?
Confirm the app has permission to monitor traffic for the target page or app flow, restart the target session, and ensure you are testing on a supported iOS/iPadOS version. If HTTPS is using a certificate pinning pattern, some requests may be intentionally hidden. Capture status and selected app settings can affect what appears in NetLens.
Why can't I copy cURL output or full headers?
Some requests can be redacted for security or privacy policy constraints, especially around authorization and sensitive payloads. If the request is multipart or encrypted payload-heavy, NetLens may provide summary fields without exposing secrets. Update to the latest version and confirm any preview or export toggles in settings.
What should I do before exporting debug output?
Review entries for tokens, session IDs, emails, device tokens, auth cookies, device identifiers, and endpoint-specific secrets. Remove or redact sensitive values before sharing screenshots or exported logs. For support, share only minimal examples and remove private endpoints when possible.
