strest

[!WARNING] Only use strest for testing infrastructure you own or have explicit permission to test. Unauthorized use may be illegal.

strest is a command-line tool for stress testing web servers with real-time stats, deterministic replay, and built-in memory diagnostics.

Why strest

• Deterministic replay without re-hitting prod.
• Built-in memory growth investigation (RSS logging + heap profiling).
• All-vs-ok latency separation so failures don’t hide tail pain.
• Config-first workflows with no JS runtime tax.
• Controller/agent distributed mode with streaming aggregation.

Quick Start

cargo install strest

strest -u http://localhost:3000 -t 30

Scenario quickstart:

# strest.toml
[scenario]
base_url = "http://localhost:3000"

[[scenario.steps]]
method = "get"
path = "/health"
assert_status = 200

strest --config strest.toml -t 30 --no-tui --summary --no-charts

Screenshots

Charts focus on signal:

• All vs ok latency percentiles show tail impact from failures.
• Throughput + inflight reveal saturation and ramp behavior.
• Error breakdown separates timeouts, transport errors, and non-expected status codes.
