What Is Stump
Stump is a self-hosted server for organizing, browsing, and reading comics, manga, and other digital books. It is built with Rust, using the Axum framework and SeaORM, on the backend, and React on the frontend, and it is released under the MIT license.
The project is developed in the open on GitHub as stumpapp/stump, has attracted a community of contributors, and is explicitly described by its maintainers as beta software ahead of a stable 1.0 release.
Key Features
Stump organizes libraries of comics, manga, and digital books and exposes them through an OPDS feed, letting users read their collection in third-party e-reader apps in addition to Stump's own web interface. It is built to be fast and lightweight, running well even on low-powered hardware such as a Raspberry Pi.
Pricing
Stump is completely free and open source under the MIT license. There is no subscription or licensing fee; the only cost is the hardware or hosting infrastructure the user chooses to run it on.
