Sourdough Lab plans
Free, and Lab+ — nothing else
Two plans only, and no third tier. This is the same feature matrix the application itself enforces, so marketing and access control can never drift apart. Lab+ membership is purchased from inside the app, so there are no payment buttons on this public site.

Every feature listed above matches exactly what the app itself lets you use, so what you read is what you get. Items marked as planned are not available yet, and we never list something here that does not exist.
