## What it is
nGrinder is an enterprise-level performance and stress testing platform consisting of a web-based controller and load-generating agents. It supports Jython-based test scripting, concurrent test execution, agent and target monitoring, and automated report generation.

## Use cases
- load test a web api with thousands of virtual users
- stress test a website before a big launch
- run concurrent performance tests from multiple agents
- generate test scripts and monitor target servers during load tests
- measure how my service behaves under heavy traffic
- performance regression testing for enterprise systems

## When to choose
- you need a self-hosted, web-based load testing platform with distributed agents
- you want scriptable stress tests using Jython/Java on the JVM
- you need monitoring of both load agents and target machines during tests
- you are testing large-scale systems and need proven enterprise tooling

## When to avoid
- you need a lightweight CLI-only load testing tool
- you want a modern actively developed project with frequent releases
- you prefer scripting in languages other than Jython/Java
- you need cloud-SaaS load testing without self-hosting

## Facets
- artifact type: application
- maturity: maintenance
- function: testing, benchmarking, monitoring, http-server
- domain: testing, performance, developer-tools
- platform: jvm, self-hosted, cross-platform
- tags: load-testing, stress-testing, jython, performance-testing, distributed-agents, devops, web-server
