"Testing if my NodeMCU web server will survive the final project presentation"

4.5/5

What do you like best about Loader.io?

As an engineering student, the best part is the free tier and how dead simple it is. I used it to stress-test the local web server I built on an ESP8266 for my smart irrigation project. Instead of downloading heavy testing software, you just paste your target URL, set it to something like 0 to 50 concurrent connections over 1 minute, and hit run. The graphs it generates are super clear and look really professional when we attach them to our final lab reports. Review collected by and hosted on G2.com.

What do you dislike about Loader.io?

The target verification process is a bit of a headache for students. To test a server, you have to verify the URL by uploading a specific token file. Since my ESP8266 server runs on a temporary IP or an Ngrok tunnel, I have to hardcode their verification token into my C++ code every time I want to run a test, which is annoying. Also, the free version only lets you keep one target host at a time. Review collected by and hosted on G2.com.

What problems is Loader.io solving and how is that benefiting you?

We were terrified that our microcontroller dashboard would crash when the external examiner and our professor tried to open it at the exact same time during our hardware demo. Loader.io helped us find the exact breaking point of our NodeMCU (turns out it crashed at just around 12 concurrent users!). Thanks to this test, we knew we had to optimize our HTTP request handling in the Arduino IDE before the final grading day. Review collected by and hosted on G2.com.
