Web UI

APXY includes an embedded Web UI for setup checks, live traffic review, and visual rule management.

Accessing the Web UI

The Web UI starts automatically when the proxy starts:


# Default: Web UI on port 8082 (proxy port 8080 + 2)
apxy start
 
# Custom port
apxy start --web-port 9090
 
# Disable Web UI
apxy start --web-port 0

Open http://localhost:8082 in your browser.

Workflow groups

The left menu is organized around the jobs you perform most often:

Group	What you do there	Learn more
Setup	Check readiness, certificate state, and capture health before debugging	Certificate Setup
Capture	Watch live traffic, inspect details, compose requests, and compare records	Proxy Traffic
Modify	Manage mocks, filters, redirects, SSL rules, network conditions, and interceptors	Mock Rules
Analyze	Review summaries, comparisons, and other investigation views based on captured traffic	Logs
Operate	Handle day-to-day controls such as environment setup and operating workflows around the proxy	CLI Reference

Core screens

Setup surfaces readiness checks and warnings before you begin a session.
Traffic is the main live capture view with filters, density controls, and a detail panel.
Compose lets you build and send requests from scratch.
Diff compares two records side by side.
Rule pages under Modify handle mocks, filters, redirects, SSL, network shaping, and interceptors.

Features

Dark and light themes — toggle in the top bar
Command palette — quick navigation to any page or action
Traffic density toggle — comfortable or compact view for high-volume capture
Filter panel — protocol tabs (All/HTTP/HTTPS/WebSocket/JSON), manual pinning, saved presets
Live streaming — real-time traffic updates via SSE

The UI is organized into workflow-based groups:

Setup — readiness checks, certificate status, and diagnostics
Capture — traffic viewer, compose, and diff
Modify — mock rules, filters, redirects, SSL, network, and interceptors
Analyze — summaries and comparison workflows based on captured traffic
Operate — supporting actions for running APXY day to day

When to choose the Web UI

Use the Web UI when you want:

a live view of traffic as requests happen
point-and-click rule editing instead of terminal commands
setup diagnostics before testing HTTPS interception or capture

Use the CLI when you want scripting, quick terminal inspection, or repeatable automation.
