No BS - just works

I love this tool. No cruft. No BS. It does what it's supposed to, and nothing more. It saved my life many, many times!

Simply excellent

I've used this tool professionally for a nnumber of years. It helps me debug HTTP services and often saves me hours of time.

It's simple to use, it shows the raw HTTP requests and responses. It always works.

Simply an excellent tool for HTTP service debugging.
