## What it is
OpenSpeedTest is a free, open-source HTML5 network speed test tool written in vanilla JavaScript using only built-in Web APIs like XMLHttpRequest, HTML, CSS, and SVG. It measures download, upload, and latency from any browser without plugins, and can be self-hosted on any static web server such as NGINX.

## Use cases
- run an internet speed test from any browser
- self-host a speed test server on my LAN
- measure bandwidth up to 10 Gbps without Flash or Java
- test network speed on phones, TVs, and consoles
- diagnose ISP connection quality over time
- deploy a speed test in Docker or Kubernetes

## When to choose
- you need a plugin-free, browser-based speed test that works on any device
- you want to self-host a speed test for LAN or enterprise networks
- you prefer a lightweight tool with no third-party dependencies

## When to avoid
- you need packet loss or advanced diagnostics beyond bandwidth and latency
- you require native mobile app features or automated scheduled testing
- you need detailed per-connection analytics or historical dashboards
