Speed Test API

SpeedOf.Me API, the first and only speed test API, allows you to measure your users' connection speed.

Without having to host SpeedOfMe software on your server, you are now able to run a SpeedOf.Me speed test right from your website or app. It is a Javascript-based API that allows you to measure the download speed, upload speed, latency, and jitter of the client. This means you can:

  • Create your own speed test service

  • Collect statistical data and benchmark the bandwidth of your users

  • Determine proper audio/video streaming quality for the client

  • Run network and connectivity diagnostics

  • Tell the user the time needed to download/upload a specific file

  • Integrate it into your IoT or smart home device

  • And more...

Why not build your own bandwidth testing service?
SpeedOf.Me API delivers the highest accuracy needed for most use cases while saving you hundreds of hours of software development and ongoing bandwidth costs required for running each speed test. SpeedOf.Me API has been in production since 2013 and is trusted by thousands of developers.
