# PerfAtlas

> The modern directory for JMeter plugins — search, discover, compare, and track the velocity of load testing extensions, with AI-ready plugin highlights. Data synced nightly from canonical JMeter plugin repositories.

PerfAtlas (https://plugins.jmeter.ai) is a high-performance static site built with Astro that aggregates JMeter plugin data, tracks daily and weekly download trends, and curates collections of plugins for common load testing scenarios. It is maintained by NaveenKumar Namachivayam (QAInsights).

## What PerfAtlas Does

PerfAtlas is a free, community-driven directory of Apache JMeter plugins. It indexes 100+ plugins sourced from the official JMeter Plugins registry (https://jmeter-plugins.org), provides real-time download statistics, and surfaces trending plugins by weekly delta. Data is refreshed nightly via GitHub Actions. The site does not sell plugins — all listed plugins are free and open source.

## Who Maintains This

PerfAtlas is built and maintained by NaveenKumar Namachivayam, a performance engineering consultant and author at QAInsights (https://qainsights.com). His expertise covers Apache JMeter, Gatling, k6, and AI-assisted performance testing. He can be found on Twitter/X at @qainsights and GitHub at github.com/QAInsights.
