[kushalghosh]

I just wanted to ask that is there any open source or free tool exists which can help to do load testing like at what no. of users the server will crash, I just want to know that on how much load(no. of users) my server will crash so that I'll be prepare accordingly when I know the numbers of users might be coming on my website.

Apache Bench aka "ab"

ab -n 1000 -c 100 http://localhost:3000/

1000 requests with a concurrency of 100

I had great success using Locust. It's extremely easy to write tests for, and you can use it both in CLI and WebUI mode.
