Free tools · no signup
A handful of small, fast sourdough calculators and helpers - all free, all in your browser. Get your feeding ratio right, name your starter, check its health and convert yeast to sourdough.
Yes. Every tool here is free and needs no signup. The calculator, name generator and yeast converter run entirely in your browser, and you get one free starter scan with no account.
No account is needed for any tool. If you want to track your starter over time - feeding reminders, a journal and bake history - that is what the free Sourdough Tracker account adds.
If you are baking, start with the starter calculator to nail your feeding ratio. New to sourdough from yeast recipes? Try the yeast converter. Worried your starter looks off? Run the health scanner.
