Testlio has you covered.
Testlio powers burstable software testing. We’ve got you covered. On any device. In any location. In any language.

Coverage matters when considering a testing partner.
At Testlio, we think of test coverage on three dimensions:
1. Devices: Broad device coverage matters in testing. Whether it’s manual or automated testing, you can deploy to a combination of racked and in-the-wild devices, across multiple OSes, platforms, and devices leveraging Testlio’s access to 1,200 real devices and AWS Device Farm.
2. Locations: In many cases, where we test is critical. With freelancers in 150+ countries around the world, including thousands in the US, we can bring people to precisely the place you require for location testing.
3. Languages: Our freelance testers and quality engineers speak, and can test in, more than 100 languages. When you need linguistic expertise, coupled with automated, functional, localization, and other QA testing services, Testlio can help.
Devices Covered
The magnitude of devices, operating systems, and environments enabling today’s apps can overwhelm QA and testing teams and thwart the best-intended coverage strategy.
Testlio’s got your ‘what’ covered with the smartest network of freelancers conducting app testing on a nearly infinite combination of real platforms and devices. Or, deploy automated tests on hundreds of racked devices across multiple OS leveraging with AWS Device Farm.

Locations Covered
Location is often paramount when it comes to test coverage. Today’s test coverage strategy must take into account the evolving ways consumers engage with technology. Apps increasingly meet consumers with a frictionless experience from the digital realm into the physical world. At work, home, the mall, while traveling, or catching a game at the ballpark.
Testlio’s got your ‘where’ covered with a global network of validated freelancers ready to tackle any testing need in any location. They are traveling, shopping, and experiencing apps in the same locations as your customers using real-device in real-world settings. Our engagement managers are coupled with client teams and test managers/test leads, organized 24/7 across AMER, EMEA, and APAC.
Countries
As your business concentrates on in-country experiences, Testlio can help. With freelance testers in 150+ countries, we likely already have coverage. And our Network team can recruit additional expert freelance testers and quality engineers anywhere you need us.
Metros
For advertisers, streaming media, sports and other providers, specific city-oriented metros matter greatly. Testlio has worked with major outlets like CBS and Fox, ensuring that for the biggest game or event, the right testers are available—live.
Homes
Whatever the app, from IoT testing on Alexa and Google voice-enabled devices, to home monitoring systems, doorbells, appliances, and more, Testlio has your in-home needs nailed.
Travels
Whether it’s on planes, trains, or automobiles – Testlio tests your app-driven experience during real-life moments of travel. Apps are used every day while ride-sharing, taking a bus, driving a car, or even tooling around on scooters. Testlio drives your travel experience test coverage home.
Work
Apps often serve as valuable resources for getting work done. Testlio covers professional and business apps in real-work situations and environments.
Stores
App-driven experiences are propelling changes in how retailers and restaurants engage. We bring real, expert testers to your stores to ensure that your app/store combinations are great.
Experiences
Your apps are used everywhere, including sporting events, festivals, and amusement parks. How do you find testers for these venues? Testlio, of course.
Anywhere
Wherever you need expert freelancers, we can be there. Have questions about a specific location need? Contact Us.
