Interfaces

Proxelar provides three interface modes, all showing the same live traffic data.

TUI (default)

proxelar
# or
proxelar -i tui

An interactive terminal interface built with ratatui. Shows a table of all captured requests and WebSocket connections with nine columns: time, protocol, method, host, path, status, content-type, size, and duration.

Key bindings

KeyAction
j / k / / Navigate requests
EnterOpen detail panel; press again to focus it for scrolling
j / k (focused)Scroll detail content
TabSwitch between Request and Response (or Frames) tabs
/Enter filter mode
EscClose detail panel or clear filter
g / GJump to first / last request
rReplay selected request
cClear all captured requests
?Show keybinding help
q / Ctrl+CQuit

The detail panel shows the full request or response including headers and body. For WebSocket connections the Frames tab lists every captured frame with its direction ( client→server, server→client), opcode, size, and payload preview.

Filtering

Press / to enter filter mode. Plain text searches across method and URL. Use column:value to scope the search to a single column:

SyntaxMatches
time:14:rows captured after 14:00
proto:httpsrows using HTTPS or WSS
method:POSTrows whose method contains POST
host:githubrows whose host contains github
path:/apirows whose path contains /api
status:404rows whose status contains 404
type:jsonrows whose content-type contains json
size:1.5rows whose formatted size contains 1.5
duration:slowrows whose formatted duration contains slow

Column names are case-insensitive. Press Enter to apply, Esc to cancel.

Terminal

proxelar -i terminal

Prints each request/response as a colored line to stdout. Useful for quick inspection or when piping output to other tools.

Output includes timestamp, HTTP method (color-coded), URL, status code, and response size.

Web GUI

proxelar -i gui

Opens a web interface at http://127.0.0.1:8081 (configurable with --gui-port). Built with axum and WebSocket for real-time streaming.

Features:

  • Interactive request table with live updates — nine columns: Time, Proto, Method, Host, Path, Status, Type, Size, Duration
  • WebSocket inspection — connections appear as live/closed rows; click to browse frames
  • Unified column:value search bar — same syntax as the TUI filter (e.g. status:404, type:json, proto:https)
  • Click a row to view full request/response detail
  • Intercept mode — pause requests, edit method/URI/headers/body, then forward or drop
  • JSON pretty-printing in the detail view
  • Light and dark mode (follows system preference)

To make the web GUI accessible from other machines:

proxelar -i gui -b 0.0.0.0

The current web GUI is designed for local use. Its WebSocket connection is token-protected and accepts localhost origins, so remote browser access should be done through a local tunnel such as SSH port forwarding until remote GUI access is explicitly hardened and documented.
