In their own words
NetworkSpy
NetworkSpy is an application-level HTTP/HTTPS debugging tool for capturing and analyzing network traffic. It can intercept HTTPS, inspect request metadata, compare requests side by side, and let users edit and replay captured traffic. Breakpoints can pause or change live requests, and response mocking is supported. It also handles WebSocket message streaming and gRPC with Protobuf decoding. Its LLM analyzer visualizes streaming tokens, tracks token usage, and reports latency for each chunk; custom viewers can display proprietary binary formats or other structured data. NetworkSpy runs on macOS, Linux, and Windows, and physical iOS and Android devices can be configured to route traffic through it for inspection. The privacy policy says inspected traffic stays on the user's machine and is not collected or monitored. The free plan has limits on LLM token analysis and other features. Personal costs $18 a year, Professional $29 a year, Team Starter $49 a month, and Business $149 a month. An individual license is limited to one device.
