## What it is
Yandex.Tank is an extensible open-source load and performance testing tool for Linux, supporting multiple load generators such as Phantom, JMeter, BFG, and Pandora. It includes test autostop, SSH-based monitoring, and integration with the Overload analytics service for storing and analyzing results.

## Use cases
- load test an HTTP API at high request rates
- benchmark web server performance with 100k+ RPS
- run automated load testing as part of CI
- generate load from access logs or URL lists
- monitor server metrics during a stress test
- stop load tests automatically once results are conclusive

## When to choose
- you need very high-throughput HTTP load generation on Linux
- you want a scriptable load testing tool for automated suites
- you want pluggable generators including JMeter or custom Python scenarios

## When to avoid
- you need a GUI-driven load testing tool
- you are on Windows or macOS without Linux environments
- you need simple ad-hoc testing without configuration

## Facets
- artifact type: cli-tool
- maturity: active
- function: load-testing, benchmarking, monitoring
- domain: performance, testing, developer-tools
- platform: python, cli
