2020 has been a crazy year so far. It has been challenging for businesses and consumers alike and I wouldn’t blame you if you wanted to just forget this year and put it behind. After a year like 2020, we’re just as excited as you are to move on and ring in the new year.
Despite a lot of challenges and uncertainty, 2020 has been *knock on wood* a relatively good year for TestMu AI. And yes, we’d like to extend a sincere thanks to everyone who has been a part of our growth journey: our champion team, our partners, our investors, and, of course, you: our valuable customers. We couldn’t have done it without you.
2020 Was Not A Good Year For “In-House” Device Labs!
As teams across the world kickstarted the WFH culture, they realized that the “in-house” device labs were not that “in-house” anymore. They were forced to embrace the cloud technologies rather rudely.
We, here at TestMu AI, realized that we have bigger responsibilities towards these WFH teams. As these testing teams no longer had access to office devices to perform testing, they were coming in droves to platforms like TestMu AI to fill in that infrastructure gap. And it was our responsibility to ensure that this transition for them is as smooth as possible. The entirety of 2020 was spent to make this experience better and better for these development and testing teams.
We launched tons of new features, launched a dedicated desktop application to help in responsive testing, scaled our infrastructure to cater to all the incoming users, launched a new developer and tester-centric community to facilitate the exchange of knowledge, and started a newsletter to keep you updated with the latest and the greatest in the world of testing.
Is that all? Well, NO!!
So let’s take a look at the many milestones we achieved this year, all because of you.
This year we introduced some of our biggest features. Geolocation Testing took our vision of providing an excellent browser compatibility testing experience one step further (more on this below). Network throttling gave our users the power to test their website or web app on low/high latency networks and offline. And there were even much more!
Given below are some of the top feature releases from this year.
The biggest challenge for testers who suddenly didn’t have access to device labs was to perform responsive testing, in a fast and reliable way. To help them, we launched a new desktop app designed from the scratch to help in faster responsive testing. LT Browser is a dev-friendly browser that will allow you to perform responsive testing on 45+ mobile and desktop device sizes.

Since its launch in June, we’ve been releasing a steady stream of new features to LT Browser, such as performance reports, hot reloading, network throttling etc. Here’re some exciting new features of LT Browser that we’ve added since the launch-

We’re just getting started with LT Browser, and 2021 will see even bigger and better features to come. If you haven’t explored it yet, make sure to check it out.

Not only did we launch one of our offerings on Product Hunt, but we did it with a bang! We launched TestMu AI Screenshot Scheduler in February, and it immediately bumped up to the #3 Product of the Day.

We went live on four marketplaces with our own plugins this year. Each of these plugins has been developed to make cloud-testing more seamless than ever.
2020 was the year that we introduced UnderPass to the world, a secure desktop application that enables you to test your locally or privately hosted web applications at TestMu AI. It helps you configure TestMu AI Tunnel without using the command line, through the GUI itself. It is now out of Beta testing with some cool new features like varying color coding for different updates, easy access and sharing of Log Directory, ability to change the Log Directory path, amongst other performance enhancements.

Additionally, in November, we rolled out an upgraded version of the TestMu AI Tunnel binary with a new user interface, enhanced security mechanisms, and much more. It comes packed with exciting features like colored logs, support for MITM mode and environment variables, new Lambda Modifiers, MagicLink feature, and the feature to Bypass hosts.
We are always looking at ways to make your testing experiences smoother than ever. Taking that into hindsight, we added a plethora of integrations for an enhanced user experience and seamless project management, continuous integration, bug management, and more. Here’s a list of integrations we went live with this year-
We love to connect with our users, readers and answer their questions every now and then. And we know that webinars are the best way to do that. Presenting our top 3 webinars of 2020-
We introduced the TestMu AI Community with a vision to help developers and testers interact, engage and grow with each other. A simple, free, and ready-to-post Q&A community developed for testers, by testers!

So in case you haven’t checked the Community yet, feel free to ask a question or answer one!
With TestMu AI Certifications, we promise to help you showcase all of your testing skills to the world. These certificates will help you enhance your resume and flaunt those secret Selenium test automation skills, web designing skills, or any other hidden skills. It is free of charge (for now!)

Our Learning Hub is a free resource for all our users, customers, and readers, and as great as it is now, it’s only going to get better. We’re creating even more content as we write for a genuinely comprehensive hub.

This year, we finally launched our weekly newsletter – “Coding Jag.” It has been hitting your inboxes (if you are a subscriber) every Thursday with a curated list of articles categorized around different spaces related to testing.


We started this year by moving to a new and bigger workspace. Though we haven’t had the pleasure of actually putting the new office to good use till this date, there’s a brighter side to it. We expanded our team three times (yes, despite the ongoing pandemic!). So we are all set to house our fast-growing team at the new premises as and when the pandemic allows us to go back.

In 2020, our total user base expanded to 350,000+ users. As a cherry on the cake, we secured a $6m fundraising round led by Sequoia Capital India’s Surge. This round also saw participation from Blume Ventures, Entree Capital, Leo Capital, along with Gokul Rajaram and Ramakant Sharma. We have launched a couple of geographic locations for data center hosting to increase infrastructure redundancy and better availability. These geographic locations target both European and US-based customers. These have also resulted in lower latencies for our customers.
Right now, we are working on multiple things at the same time. We are working on bringing out more features around performance, bringing in support for more testing frameworks, and are expanding our infrastructure even further to cater our users who are spread across 132 countries. Over the past year we have emphasized heavily on improving overall quality and performance of the TestMu AI cloud and 2021 won’t be any different.
We are currently in the process of expanding into accessibility testing, native app testing, to name a few. We will also be going live with our own set of real devices to test your website and web apps. Additionally, we will also be targeting more locations in Asia and Australia to increase our geo presence in terms of infrastructure, and there’s a lot more on the horizon!
We are also working on bringing a blazingly fast full featured automation infrastructure that will change the way you run your tests at scale. But that’s for 2021 !!!
As always, none of this would be possible without you, our customers. Thank you for putting your trust in TestMu AI and for giving us a chance to work on a product we love.
So from our whole team of TestMu AI, we want to wish you all the best for a productive and happy 2021! With that, we’ll be signing off for 2020 to spend a little time with our loved ones before heading into the new year. And we’re positive it’s going to be a good one.
And yes, what has been your favorite new addition in 2020? Let us know in the comments below.
Happy New Year!
