I have a love (mainly) and hate (tiny bit) relationship with burpsuite. It would be really nice if there was competition. The last time I looked at ZAP (a while ago) it was still a chaotic clone of burp that didn't seem very promising.

I appreciate Caido because of the ability to save projects in the free tier, which I use for (personal use) different projects and tinkering. Burp Pro is my daily driver at work, and I think Caido could certainly use some improvement to their UI/UX, as it's about as bad as Burp's (which isn't great).

The speed is an awesome gain though, as it's truly lightweight and runs a million times better than Burp. Even without Extensions, some days my Burp Pro is just randomly crashing and gobbling up CPU/RAM for no obvious reason and requires a program or system restart. I've never run into the same issue with Caido.

Upvoted and will look closer if only because they have a "essential only" cookie banner.
