Leanpub is a Canadian self-publishing platform for technical books, founded in 2010 by Peter Armstrong. The platform's distinctive feature is the publish-while-writing model — authors release in-progress books to early customers and update them iteratively as they're finished. Many widely-read modern dev books (including Domain-Driven Design Distilled, The Cucumber Book, and others) launched on Leanpub.
The CourseFlix listing carries two Leanpub titles: Stratospheric — From Zero to Production with Spring Boot and AWS and the Django for Beginners / APIs / Professionals trilogy. Material is paid and aimed at developers picking up Spring or Django through book-format learning.
