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.
Proxyfor
Proxyfor is a proxy command-line tool for capturing and inspecting HTTP, HTTPS, WebSocket, and secure WebSocket traffic. It works in forward or reverse proxy modes and offers both terminal and web interfaces. Captures stream as requests and responses arrive, allowing filtering, searching, and export to Markdown, cURL, or HAR files. The CLI can filter HTTP(S) traffic with a regular expression matching method and URI, or by MIME type. HTTPS inspection requires installing Proxyfor’s CA certificate on the target device; the project describes a built-in certificate installation app. Proxyfor runs on Linux, macOS, Windows, web, and self-hosted deployments. Installation is documented through Cargo, Docker, or downloadable binaries, including a single-file portable executable for desktop systems. Docker instructions mount a configuration directory and expose port 8080. The project is open source under either the MIT License or Apache License 2.0. GitHub lists version 0.5.0 as the latest release.
