51Degrees

A lot happened in 2023 – industry changes and major device releases dominated the device detection market. In response to this, we continuously updated the 51Degrees service.

We’ve retired the HAProxy git.51degrees.com service. We recommend you get started with Version 4 which retains features such as in-memory data upgrades and multi-threading support.

We’ve updated our predictive algorithm to tolerate corruption in the User-Agent and User-Agent Client Hints data. The changes result in a more accurate device detection.

In the next round of device detection improvements to 51Degrees, we’ve improved our data file release schedule.

We’ve improved our device detection accuracy following feedback raised by our customers, and we’re pleased to announce the release of our upgraded algorithm and data files.

As we begin a new year, let's look back at what 2022 had in store for 51Degrees.

We encourage users of our service to enable usage sharing so that our algorithm can discover new or rare devices. This blog delves deeper into what we do with the data you provide through usage sharing.

Version 4.4 of the 51Degrees service, which contains full User-Agent Client Hints support, has now been released. Find out more about the changes and how to get started with UA-CH support.

The free 51Degrees Optimize by Device & Location WordPress plugin allows website owners to seamlessly integrate our real-time data services onto their WordPress site. Gather more insights into your website visitors and provide locally relevant content with ease.
