Readias

Readias is an open‑source e‑book reader and digital library platform that was first released in late 2015 by the Readias Project, a consortium of developers from the open‑source community. The project was founded with the goal of creating a lightweight yet powerful reader that could run on a wide range of devices, from smartphones and tablets to desktop machines and embedded systems.

From its inception, Readias emphasized modularity and extensibility. The core engine is written in C++ and uses the Qt framework for its user interface, while the file‑management subsystem supports a variety of e‑book formats including EPUB 3, PDF, HTML, and plain‑text files. Features such as full‑text search, annotation, bookmarking, and adjustable text layouts (font size, line spacing, theme) were built in early on. In addition, an optional web‑service component allows users to sync their library and reading progress across multiple devices through a simple RESTful API.

The platform has attracted attention for its efficient rendering pipeline, which uses the Skia graphics library to provide smooth page turns and high‑resolution display on high‑density screens. Many reviewers noted that Readias' small footprint makes it suitable for low‑power devices used in developing regions, and the community has produced add‑ons for reading in multiple languages, including right‑to‑left script support.

Although the project has seen a steady increase in contributors, it has also been the subject of a few controversies. In 2018 a licensing issue involving a third‑party PDF parsing library forced the developers to replace the component and re‑license the project under the GPLv3. Subsequent releases resolved these problems and the project is now backed by a foundation that provides sponsorship and oversight.

At present, Readias continues to be actively maintained on GitHub, with the latest stable release in 2024. Its community of developers ranges from hobbyists to academics, and the platform is used in educational settings and by libraries that require an open‑source alternative to proprietary e‑reading software.
