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

|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.

Scam - No weight held in their product.

|Twilio

Literally zero recommendations. Committed pure fraud in my eyes and I dont see myself ever using their platform at all. They ask for you to pay for their service first before youre even allowed to use their service which goes through an AI generated approval process. Extremely unfair.
