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

Without having to host a 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 which allows you to measure download speed, upload speed, latency and jitter of the client. This means you can:

  • Create your own speed test service!

  • Collect statistical information and benchmark the bandwidth of your users

  • Decide what audio/video streaming quality is suitable for the client.

  • Tell the user how long it exactly takes to download/upload a specific file

  • Integrate it in your Internet connected hard-ware/equipment

  • And more...

SpeedOf.Me API gives you the accuracy you need while it saves you hundreds of hours of development time and brandwidth costs. It's been in production since 2013 and is trusted by thousands of developers
