What our customers are saying...

We use the WhatIsMyBrowser API to parse User Agents to determine browser compatibility with our product. It makes it easy to politely tell people that cio-pulse.com will not run on their Android-based TV ;) The WhatIsMyBrowser API is straightforward to use and does exactly what it says on the tin.

Dave - CIO Pulse

We are a boutique eLearning development company and while most of our users do not experience issues, occasionally their browsers or settings cause us problems.

To diagnose the issue and get it resolved quickly, we rely on WhatisMyBrower.com. Makes our job so easy. -- Thank you

Brett and the crew at whatismybrowser.com worked really hard to deliver us a product in the user-friendly form of an Excel file. This Excel file allows members of our team who have no knowledge of programming languages, to query user-agent strings and utilise the whatismybrowser API.

Extracting results and categorising our customers by the type of device they use has never been quicker!

Also, Brett’s communication is A+

LUXE customers are a global bunch who use a wide range of devices. We adopted the whatismybrowser.com API to detect their system details, so we know exactly what they're using (and don't have to bother them with such trivial questions when they make contact).

The API saved us heaps of development time, freeing us up to focus on the fun stuff!

The API accurately ensures all our customers meet the minimum browsers requirements for using VEDAMO Virtual Classroom. It was really easy to set up and the API responds quickly to our requests.

The API makes it very easy to determine which of our users need to update their browser as a first step to diagnosing their problems

Aaron - Storyboard That CEO

WhatIsMyBrowser API enables our system to identify which platform is requesting link previews based on their user agents so we can provide better insights to our customers

Franco Méndez Z. - Flayyer

MoovTO is a URL shortening service that offers its users an informative dashboard and link usage analytics.
The WhatIsMyBrowser.com API enables us to parse user-agents easily and enriches our dashboard with minimum development time.

The WhatIsMyBrowser API does what is expected at a low cost. At our e-commerce site we use the API to protect our data from web scrapers and search engines who put lots of stress on our huge database of appliances and parts.

Their customer service is also just perfect, when we first heard of the WhatIsMyBrowser API we asked a question about their service and directly received a test subscription for 2 months for a paid plan. We would most certainly recommend their API to others.

Bas van der Zande - Onderdelen Planet

We launched an internal webapp five years ago and had recurring issues with people running default browsers on Android or out of date versions of Chrome. We needed to troubleshoot this faster and more automatically. We'd been directing people to whatismybrowser.com as part of the original process to read us back their browser details which was much more effective than straight up asking people what their browser / version as.

After we found the API, we were able to automate an interaction which typically took us 20 minutes of back and forth and eliminate the issue entirely.

It's been running seamlessly for five years and since then we haven't had to worry about a common scenario that used to crush our support staff in the early days.

We use the API to verify if customers are using a browser compatible with our application. The API helps to restrict and redirect customers to a browser that is compatible with our application. This saves us a lot of time and effort as it prevents unnecessary calls to our support team.

Not sure if the API is right for you?

Here's a brief list of questions to help you decide if you need the API and which part to use

Features of the API

The whatismybrowser.com API contains a number of advanced features, helping you with your website visitors

Actively developed

As well as updating the User Agent Parsing library every day, we also spend a lot of time thinking about and improving the API itself.

We listen to your suggestions and feedback and happily incorporate your ideas into new features or options. It's where a number of our features actually came from! So if there's something that you'd like to see us offer, just let us know and we'll see what we can do.

Here to stay

But don't worry, as we add new features we won't pull the rug out from underneath you - if you're using a feature of the API you can rest assured it will always be there; we won't make your life harder by removing or changing things. For example, we deprecated version 1 of our API over four years ago, but it's still running for the handful of customers still using it.

Got questions? We'd love to answer them. Send us a message right now

  • Never update your libraries again - Use the API and you'll always be using the latest version of the user agent parser. No libraries to download and maintain. That's one less thing for you to worry about!
  • High availability - We run on AWS, providing you with low latency requests and high availability.
