## What is NetDebug?

NetDebug is a practical network diagnostics toolkit for developers, IT professionals, and anyone troubleshooting connectivity. Test reachability with ICMP ping, inspect the route with traceroute, check TCP ports, send HTTP requests, and connect to MQTT brokers from one focused, cross-platform app.

Save reusable requests, broker profiles, headers, subscriptions, and authentication profiles. Use Basic authentication or OAuth2 client credentials, inspect JWT claims without sending a live token to a third-party service, and keep passwords and client secrets in the platform's secure storage. Results are presented as readable, copyable transcripts so they can be shared with a team.

Features
- ICMP ping, TCP port testing, and traceroute with live, cancellable results
- Run the core network tests together against their effective targets
- HTTP client with common methods, headers, request bodies, redirects, timeouts, Basic auth, and OAuth2 client credentials
- MQTT client over TCP or WebSocket with TLS, MQTT 3.1.1/5.0, subscriptions, publishing, and Basic or OAuth2 authentication
- Saved requests, broker profiles, subscriptions, headers, and credential profiles
- Import and export collections, with credentials excluded by default
- JWT claim and expiry inspection for OAuth2 access tokens
- Light and dark themes, responsive layouts, copyable output, and iOS share support
