About BrewLab

BrewLab is a small, independent project built by home coffee enthusiasts, for home coffee enthusiasts. We were tired of digging through forum threads and calculator apps stuffed with ads just to work out a 1:16 ratio, so we built the tools we wished existed.

What we care about

• Practical, not preachy. Every tool answers a real question you'd actually ask at 7 a.m.
• Free, forever. No premium tier, no ads, no tracking scripts.
• Fast and offline-friendly. Everything runs in your browser — the page works on a train or in a kitchen with weak Wi-Fi.

Who it's for

Amateur home baristas and specialty coffee enthusiasts working with a pour-over dripper, a French press, an Aeropress, a Chemex, a moka pot, or a home espresso machine. If you weigh your coffee, BrewLab is for you.

How it's built

BrewLab is a static site: plain HTML, CSS and vanilla JavaScript. No backend, no accounts, no cookies beyond what your browser sets by default. That's not a limitation — it's the point.
