About CrumbLab
CrumbLab is the sourdough simulator that predicts your bread before you bake it.
Why CrumbLab?
Most bread tools are just calculators — they give you numbers but no guidance. CrumbLab combines a smart calculator with predictions, a step-by-step timeline, a troubleshooter, and bake timer notifications. All in one free tool, no ads, no clutter.
What makes CrumbLab different?
Not just numbers
Other tools give you ingredient amounts. CrumbLab predicts your crumb structure, crust color, sourness level and difficulty — before you start.
Complete guidance
From choosing a preset to pulling bread from the oven. Step-by-step timeline, technique tips, and troubleshooting all in one place.
Free, no ads
No tracking, no ads, no paywalls for core features. CrumbLab is built by bakers, for bakers.
