I built BuzzBench because I was frustrated with how complex performance testing tools have become. And I was ending up writing my own scripts to test endpoints and manually check out resource usage at the time of testing.
Looks neat, but I hate the "limited free" thing. What's the actual price? If I make this product a part of my team's workflow, what's the future sticker shock?
Few years ago, I had to load test production site for upcoming events. Local test was unrealistic. Some testing tool was re-using connection. I used loader.io to test. There was some issues I can't recall but it was great for both frontend and backend. I was able to test frontend at around 10 gbps.
