Fermentory
Detect, scale & shop any homebrew recipe — free
A free Chrome & Edge extension that spots homebrew recipes on any page, scales them to any batch, converts units, and builds a shopping list — locally, no account, no tracking. Optional one-time $5 Pro adds brewing calculators, BeerXML export & more.
Hey Product Hunt 👋
I ferment cider and seltzer at home, and I kept doing the same tedious thing every time: find a recipe online → manually scale it to my batch → convert the units → write out a shopping list. Over and over.
So I built Fermentory to do it for me. It detects a recipe on any page, scales it to whatever batch size you want, converts the units, and builds the shopping list — without copying anything into a separate app.
A few things I cared about:
- It runs entirely in your browser — no account, no sign-up, and it collects zero data. I didn't want to make another creepy extension.
- It's free. There's an optional one-time $5 Pro (no subscription) for the deeper stuff — brewing calculators, BeerXML export, a brew journal, ingredient inventory — but the free version does the core job.
It's still early, so I'd genuinely love your feedback — what's missing, what's clunky, what you'd want next. Thanks for checking it out! 🍻
