Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

k6.io overview
What is k6.io?
WHY LOAD TEST?
Time is money – Most websites and applications are revenue generating tools for companies and
poor performance translates to customers lost.
Performance matters - 47% of PC visitors and 69% of tablet visitors expect response times equal to or below 2 seconds (Akamai, 2012); 18% of shopping carts are abandoned due to slow website performance (Radware, 2013); 68% of website owners experienced performance or stability problems in 2012 (Load Impact, 2012).
The complexity of mobile – Performance is the most important differentiator when it comes to mobile app adoption, use and abandonment rates. A small delay in load-time might seem like a minor issue, but in reality even a small change in latency – from 2ms (broadband) to 400ms (3G network) – can cause a page load time to go from 1 second to 30 seconds.
Cost Savings – There are many parts of the web architecture such as web servers, load balancers, firewalls, Internet service providers, third party applications and local internet service providers. Load testing allows you to pinpoint bottlenecks in different parts of the web architecture so you only upgrade what you need to.
