## What it is
Drill is a lightweight HTTP load testing tool written in Rust, designed as a JVM-free alternative to tools like JMeter. Benchmark plans are defined in YAML files with Ansible-inspired syntax, supporting request chaining, assertions, templating, and CSV-driven data.

## Use cases
- load test my http api
- stress test a web server without jvm
- run benchmark scenarios from yaml files
- simulate concurrent users hitting endpoints
- jmeter alternative written in rust
- chain http requests with variable interpolation in load tests

## When to choose
- you want a fast, lightweight load tester with no JVM dependency
- you prefer declarative YAML benchmark plans over scripting
- you need request chaining, assertions, and CSV-driven payloads in load tests

## When to avoid
- you need a GUI or detailed real-time metrics dashboards
- you require protocol support beyond HTTP
- you need distributed load generation across multiple machines
