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
