A terminal-based load testing tool that brings real-time performance analysis directly to your command line. Ali lets you measure HTTP request performance with an embedded UI that displays live charts for latency, percentiles, and request metrics as tests run.

Key capabilities:

Real-time visualization - Watch latency trends, percentile changes, and request metrics update live on interactive charts
Interactive terminal UI - Click and drag to zoom into specific time ranges, switch between chart views with keyboard shortcuts
Flexible configuration - Control request rates, test duration, custom headers, connection limits, and worker counts
Mouse support - Intuitive interaction with charts and controls directly in the terminal
Cross-platform - Runs on macOS, Linux, Windows, and FreeBSD
Export results - Save test data for further analysis and reporting
Advanced options - Support for POST requests, custom bodies, TLS certificates, DNS resolvers, and HTTP/2 control

Ideal for developers, backend engineers, and system administrators who need to test APIs and services interactively without leaving the terminal. Perfect for quick performance checks during development or comprehensive load testing campaigns.
