Why Testlio?

A Proven Approach to Software Testing

QA leaders have learned that managing outsourced testing vendors or inexperienced crowdsourced testers delays progress without producing results. Today’s best approach is networked testing – an evolution of in-house, outsourced, and crowdsourced testing practices. Quality assurance at its finest.

Testlio’s flexible managed services formula reduces, not increases, your workload by combining professional services, with a global network of skilled and validated freelancers, and best-in-class testing software to power efficiencies. Fully-managed or co-managed. Your choice.

Quality of Testers

With validated freelancers in over 150 countries, Testlio offers an elite pool of the best-trained, most-motivated testers and quality engineers in the business. Only 3% of the tester sign-ups into the Testlio Network are accepted.

Freelancers are invited into Groups based on specific testing strategies and approaches. From automated testing to functional testing to user experience testing and everything in between, Testlio’s recommendations engine matches the right testers and quality engineers to your specific project.

  • Our testers live and behave like your customers with a diversity of devices, global locations, wifi environments, and languages.
  • Our on-demand quality engineers create, run, optimize, and diagnose automated tests, using script management frameworks like Appium and Selenium and technologies like Python, Java, and Javascript.
  • Our testers work in short bursts to avoid fatigue and maintain objectivity, augmenting your QA team during periods of peak demand.
  • Our testers are paid by the hour, not by the bug, which leads to higher quality issue detection and thoughtful reporting.
  • Our testers earn Ratings based on engagement attributes that help guide them on pathways of growth and mastery.
  • Coordinators and Admins can view full freelancer Profiles to aid in selection.

“They are great at communication, they got the feel for how our app works very quickly and asked intelligent and relevant questions. Whenever we were ready to push a version out to test their test cycles were fast and thorough. I have high confidence in them as a company which took some pressure off (they are very reliable).”

Laura Alexander
Product Manager at Digital UK


With Testlio, you have visibility into every step of the testing process – from freelancers, devices, and test cycles, to issues uncovered. Further, you can learn about and communicate with all of the freelancers on your project.

  • Visibility into data captured including the number of bugs, devices, locations, languages, and overall test execution – serves as a benchmark on test cycles, issues, and hours to manage.
  • Carefully planned testing hours used to apply to projects of any type with unused hours available for more coverage as needed.
  • Unlimited licenses so your entire team can establish accounts and use Testlio software.
  • No hidden fees or upcharges for anything. Ever.

“Other companies on pay-per-bug models weren’t uncovering the real issues that most affected our users.

We appreciated the professionalism of Testlio’s testers week in and week out as we strive to meet customer expectations.”

Heather Daigle
QA Lead at Lyft

Augmenting In-house

We tackle your resource shortages and surges in project load with experienced, on-demand manual and automated QE freelancers. Within a single platform you manage day-to-day automated and manual testing with fewer resources most of the time, reducing costs while maintaining full coverage when it’s needed.

What do in-house QA teams get with Testlio?

  • Quality engineers, extensive integrations, holistic platform, and strategic services needed to seamlessly combine automated and manual testing.
  • Burstable teams of freelancers, in distributed locations, working within narrow run windows on real devices. Work often occurs overnight and/or on weekends. Results are fast and tuned to the rhythms of agile engineering teams.
  • Co-managed experiences and a single bespoke, optimized, broad, and flexible software testing platform.
  • A high volume of QA resources for native app releases only when necessary. This approach allows internal teams to manage day-to-day testing with fewer resources most of the time, reducing costs while maintaining full coverage when it’s needed.
  • Coordinators and Admins leverage Testlio’s filters and recommendations engine to create, update, and extend  Groups.


“Testlio’s PMs will do a great job of putting together test cycles and test cases with minimal input from us, but they will also accept and integrate as much detail as we can provide. Sometimes we provide a huge list of test cases for a new feature and the testers execute them all. Other times we say ‘try anything that you can think of that touches feature X’. We get quality results either way.”

Mark Shaw
CTO at Strava

Bursting Outsourcing

Outsourced or offshore qa testing was introduced to replace in-house teams but comes with a set of challenges, including limited transparency, disconnected processes, and inflexible capacity management.

Testlio’s more efficient approach introduces a combination of freelance quality engineers and a highly burstable team of testers who are deployed to a specific release cycle, often in key locations and languages, in minutes, overnight, and over weekends depending on your needs.

Why Testlio vs. Outsourcing?

  • Testlio engagements are highly transparent and holistically traceable with visibility into all moving pieces at play.
  • Testlio blends into DevOps processes in support of continuous testing. Both manual and automated testing can be networked into code as it is checked in—ensuring the rapid completion of visual, functional, and other tests.
  • Bespoke testing platform to manage builds, tests, plans, runs, issues, teams and reports. Full visibility into test cycles, freelancers, issues, hours to manage, and utilization serves as a benchmark for future projects.
  • Co-managed experiences with expert project managers and skilled freelancers who provide essential thought leadership and insights.


“The reporting system was great. The way it’s organized is very straightforward. It’s a component of the communication flow as well.”

Anna Desilva
Software QA Engineer at Flipboard

Complementing Automation

A blend of both automation (to increase unit-level test coverage and depth of testing without increasing overall costs) along with a set of manual tests (for more complex and exploratory testing), is the best way to achieve increased overall test coverage.

How does Testlio complement your automated testing?

  • Integrating the design, build, and management of both automated and manual test runs and results with your engineering workflows.
  • Automatically send new compiled builds to Testlio to trigger either manual and automated testing runs via API endpoints. You can align Runs with builds from your CI/CD pipeline. You can also manage each test run in a bespoke fashion.
  • Receive free device slots and 100 hours/per month to process and deploy your automated tests on racked devices across multiple operating systems.
  • Supplement automated tests with real device utilization.
  • Integrated reporting and insights to review and validate all test results and defects.


The value Testlio brings is unique, just like their people.

They bring thought, originality, and a diverse background of experiences to bear when it comes to testing, and that’s something we’re a long way off from being able to automate.”

Jai Govindani
Chief Technology Officer at Red Planet Hotels

Outperform Crowdsourced

The number one flaw with the traditional crowdsourced testing model is that the low skilled testers, incentivized to find non-essential bugs, need to be managed and their work reviewed. The hidden costs of managing crowdsourced testing come from the need for detailed test plans, time spent going through non-essential bugs, and an inconsistent team of testers. This extra work challenges the cost-benefit ratio of working with a crowd of testers.

How Testlio outperforms with managed Crowdtesting.

  • Testlio utilizes a networked testing approach, a powerful evolution of crowdtesting best practices tuned to deliver exceptional automated and manual quality assurance. Speed. Coverage. Economics.
  • Co-managed experiences with named professional engagement managers who understand your software inside and out.
  • Testlio deploys dedicated, multi-time zone teams of expert freelancer testers and quality engineers exactly where you need them: at stores, in stadiums, in metros, in countries, etc. while retaining valuable process and product knowledge for more reliable results and faster turnaround.
  • Networked testing uses a high percentage of consistent freelancers run-to-run—while also rotating new testers for fresh insights and perspectives.
  • Traceable actions and proactive reporting process giving visibility into the entire testing journey: what’s tested, when it’s tested, what devices are tested, costs, outcomes, and recommended actions.


I love Testlio’s flexibility and willingness to accommodate our needs.

I can ask testers to look for crashes and undesirable behaviors that we know exist but haven’t been able to reproduce on our own.”

Benjamin Wolak
Mobile QA Engineer at Strava
