Introduction

This repository contains the freely available 'lite' version of the 51Degrees device detection data file.

It has fewer properties, is built from a subsection of all devices and is updated less frequently than the paid-for data files.

This repository uses Git LFS rather than storing these large binary files directly.

Files

• 51Degrees-LiteV4.1.hash - The 'lite' on-premise device detection data file.
• 20000 User Agents.csv - A test file containing 20,000 of the most commonly observed User-Agent values. Each line contains a single User-Agent.
• 20000 Evidence Records.yml - A test file containing 20,000 of the most commonly observed sets of headers that are useful for device detection. This is a replacement for the 20000 User Agents file that includes values for User-Agent Client Hints. This is a multi-record yaml file where each line contains the HTTP header name and value as the key/value pair. Values may be wrapped in single quotes.
