Senior Software Engineer Information Technology and Services Small-Business (50 or fewer emp.) 5/7/2024 "Stress test like a hero" 3.5/5 What do you like best about Loader.io? It is really easy configure a test case, literally it took me 30 seconds to stress test my home page and I got my result in next 60 seconds. All in all, in 90 seconds I got to know how strong my landing page is. Other tools let you test any endpoints disregarding the privacy and ownership of endpoint but with loader.io, I was able to verify my ownership in within 10 seconds just uploading a file. Their simulation feature informs you about how it would test the endpoint which makes understanding your result a breez. I was able to schedule my stress test and webhook had let me know the results on my email. It was really a nice feature. Their documentation is comparetively comprehensive. Review collected by and hosted on G2.com. What do you dislike about Loader.io? UI is little bit old in style and flacky. A progress bar should be there to indicate the state of stress test in progress. One another things which I dislike that there was no way to fuzzy test endpoints with random data Review collected by and hosted on G2.com.
