After trying to find something similar myself, originally I found some "methods" online to bypass the trial time, but I eventually just gave in and bought a license - and IMO it does exactly what it says on the tin, and is still updated and is cross platform so I think it's worth it.
But if anyone knows of any nice GUI tools that are similar do share!
EDIT: Just thought I'd mention how I use it. Basically I use it like the chrome network tools, but I intercept POST requests to the server and try to much with the data that's sent to make sure the backend isn't blindly trusting the client, or to see if there's weird ways I can break the code with special input, etc.
