universal-user-agent is a JavaScript library designed to parse and analyze user-agent strings in a consistent manner across different environments, such as browsers and Node.js. It helps developers identify the user's browser, operating system, and device type, enabling them to tailor their applications based on the user's environment. While universal-user-agent is a powerful tool for user-agent detection, there are several alternatives available in the ecosystem. Here are a few notable ones:

• bowser is a lightweight and fast browser detection library that parses user-agent strings to identify the browser and its version. It provides a simple API for checking browser capabilities and is particularly useful for feature detection. If you need a straightforward solution for detecting browsers without the overhead of a more comprehensive library, bowser is an excellent choice.

• detect-browser is another user-agent detection library that focuses on simplicity and ease of use. It provides a minimalistic API to identify the browser and its version, making it a great option for projects that require basic browser detection without additional complexity. If you want a quick and efficient way to determine the user's browser, detect-browser is a solid alternative.

• platform is a library that provides a simple way to detect the user's platform (browser, operating system, and device) based on the user-agent string. It offers a clean API and is particularly useful for applications that need to differentiate between various platforms. If your project requires platform detection along with user-agent parsing, platform is a good option.

• ua-parser-js is a powerful and comprehensive user-agent parsing library that can identify browsers, operating systems, and devices. It supports a wide range of user-agent strings and is highly customizable. If you need detailed information about the user's environment and require a robust solution, ua-parser-js is an excellent choice.

• user-agent is a simple library that focuses on parsing user-agent strings to extract relevant information about the user's browser and operating system. It is lightweight and easy to use, making it suitable for projects that need basic user-agent parsing without additional features.
