## What it is
Apache JMeter is a 100% Java open-source application for load testing and measuring the performance of web applications and other services. It supports many protocols (HTTP/HTTPS, REST/SOAP, JDBC, FTP, LDAP, JMS, mail, TCP), offers a GUI test IDE with recording, headless CLI mode, distributed testing, and dynamic HTML reporting.

## Use cases
- load test a web application with thousands of concurrent users
- measure API response times under heavy load
- stress test a REST or SOAP webservice
- run headless performance tests in CI
- record and replay browser traffic as a test plan
- generate HTML performance dashboards and live metrics to InfluxDB
- load test a database via JDBC

## When to choose
- you need protocol-agnostic load testing beyond plain HTTP (JDBC, JMS, LDAP, FTP, mail)
- you want a mature GUI for recording, building, and debugging test plans
- you need distributed load generation from multiple machines
- you want ready-made HTML performance reports

## When to avoid
- you only need simple scripted HTTP load tests and prefer code over GUI (consider k6 or Locust)
- you need functional/unit testing rather than performance testing
- you want a lightweight tool without a JVM dependency

## Facets
- artifact type: application
- maturity: stable
- function: load-testing, benchmarking, testing, gui, cli, monitoring
- domain: testing, performance, developer-tools, web-development
- platform: jvm, cross-platform, windows, cli
