Ochre

Ochre is built for content businesses. Wagtail handles the editorial side with page types for articles, courses with lessons and a public archive, while Django takes care of members. It includes allauth sign-in, Stripe subscriptions with free, monthly and annual tiers, paywalled sections, email newsletters sent through Postmark, and a member dashboard with reading history.

It is opinionated that editors should never need to touch code: tiers, paywall rules and newsletter sends are all managed from the Wagtail admin. The limitation: it is not a general SaaS starter. If your product is software rather than content, most of the page models and paywall logic will get in your way.
