Recording web proxy - structure view, throttling, Map Local/Remote, repeat

ScreenshotScreenshotScreenshot

Web Traffic Inspector is a Linux alternative to Charles Proxy. It runs a real
local recording proxy (default 127.0.0.1:8889) and shows every request that
passes through it.

FEATURES:
- Structure view: a tree grouped by host and URL path with request counts,
bytes, average duration and error counts, plus a sequence list and full
request/response details (headers, decoded bodies, timings).
- Bandwidth throttling: real token-bucket rate limiting of download and
upload bytes plus added latency, applied to proxied HTTP traffic and to
HTTPS CONNECT tunnels. Presets (56k, DSL, 3G, 4G) or custom values, with a
live graph of the measured throughput.
- Map Local: answer matching URLs with a local file or folder.
- Map Remote: redirect matching requests (or tunnels) to another host/port.
- Repeat: send a request N times (optionally concurrently) and get min / avg
/ median / p95 / max / standard deviation, requests per second and a
status histogram.
- Export sessions to CSV and HAR 1.2; export repeat results to CSV.
- HTTPS is tunnelled (host and byte counts only) unless you enable SSL
proxying, which uses a local CA generated with the openssl binary and only
works in clients where you import and trust that CA. HTTP/1.1 only.

Configure your browser or set httpproxy / httpsproxy to the proxy address;
the app does not change system proxy settings. Responses are buffered before
forwarding; WebSocket upgrades are not supported.
