ali
HTTP load testing tool with real-time TUI charts
TLDR
SYNOPSIS
ali [options] target
DESCRIPTION
ali is a terminal-based HTTP load testing tool that generates HTTP load and plots the results in real-time directly in the terminal. It combines the load generation capabilities of tools like vegeta with live terminal charts showing latency, percentiles (p50, p90, p95, p99), throughput, and bytes in/out. The interactive TUI supports mouse-based zooming into charts for detailed analysis.
Written in Go, ali supports HTTP/2 by default, custom TLS certificates, configurable concurrency, and result exporting for downstream analysis.
PARAMETERS
-r, --rate n
Requests per second; 0 for max speed (default: 50)-d, --duration duration
Duration of the attack; 0s for infinite (default: 10s)-w, --workers n
Initial number of workers (default: 10)-m, --method method
HTTP method (default: GET)-t, --timeout duration
Request timeout (default: 30s)-b, --body string
Request body as a string-B, --body-file file
Path to file for request body-H, --header header
Custom header (repeatable)-c, --connections n
Max idle connections per host (default: 10000)--export-to dir
Directory to export results--insecure
Skip TLS certificate verification--no-http2
Disable HTTP/2-K, --no-keepalive
Disable keep-alive connections--resolvers addrs
Custom DNS resolver addresses
CAVEATS
The terminal UI requires a terminal that supports standard escape sequences. Running with very high request rates may be limited by system resources and network capacity. Setting duration to 0 runs the attack indefinitely until manually stopped.
HISTORY
ali was created by Ryo Nakao (nakabonne), a Go developer based in Tokyo, Japan. The tool was inspired by vegeta (HTTP load testing) and jplot (terminal plotting), combining both into a single real-time tool. It is open-source under the MIT license.
