I've been working on a new web-based brewing software suite.

I'd been wanting an all-in-one place for various calculators and recipe creation and I wanted it online so I could get access to it from wherever. I never was able to find what I was looking for, so last month I started working on it.
It's far from complete, but there's a good recipe creator, and a starting set of calculators plus a searchable database for those recipes made public. A few recipes up so far, but hopefully a lot more to come.
