Take a Speedtest

Only modern browsers are supported (IE11, latest Edge, latest Chrome, latest Firefox, latest Safari)

• Download
• Upload
• Ping
• Jitter
• IP Address
• Telemetry (optional)

• A reasonably fast web server with PHP (see doc.md for details and use without PHP)
• Your server must accept large POST requests (up to 20 Megabytes), otherwise the upload test will fail
• It's also better if your server does not use compression, but it's not mandatory

• Debian 9.0 with Apache
• Windows Server 2016 with IIS
• Ubuntu (External)

Also, here's an example config on Ubuntu 16 LTS

• See the examples
• Read the wiki
• Read doc.md

Please see the docker branch

A Node.js implementation is available in the node branch, maintained by dunklesToast.
