# JMeter Tools

Interactive helpers for common load-testing decisions. All tools run **in your browser** on [docs.jmeter.ai](https://docs.jmeter.ai): no account, no upload of test data.

## Why these tools

Docs alone rank for “what is…”, but practitioners search for calculators and cheat sheets. Each tool has shareable URL state, SEO metadata, and links back into the manual so answers stay grounded in JMeter concepts.
