ShelfDroid is a third-party Android client for self-hosted Audiobookshelf servers. It lets users browse audiobook and podcast libraries, stream books and episodes with synchronized listening progress, and download them for offline playback. The app includes chapters, bookmarks, a sleep timer, playback-speed controls, and other player functions; accounts with permission can also manage backups, API keys, users, logs, server settings, sessions, notifications, authentication, metadata, and other server features. ShelfDroid is open source under the GNU Affero General Public License v3.0.

Parker is a self-hosted comic media server for organizing and reading CBZ and CBR files, using the filesystem as the source of truth. It parses metadata from ComicInfo.xml archives and organizes a library into series, volumes, and comics, with support for collections, story arcs, stacks, reading lists, and smart lists. Its reader supports manga right-to-left mode, double-page spreads, long view, bookmarks, navigation from series and lists, and per-comic reading settings. The server also provides multi-library access controls, metadata and storage reports, duplicate and corruption detection, background scanning, and optional parallel thumbnail generation.

Karakeep is a self-hostable bookmark-everything application for links, notes, images, and PDFs. It fetches link metadata, archives complete web pages with Monolith to help protect against link rot, can archive videos using yt-dlp, and supports browser extensions, mobile apps, offline reading, RSS ingestion, and importers from several bookmarking services. It provides full-text and semantic search, OCR for image text, lists and collaboration, highlights, rule-based management, and bulk actions. LLM-based automatic tagging and summarization can use local models through Ollama; the project also provides a REST API, CLI, multiple clients, and support for browser-bookmark synchronization via Floccus.

KCC is a cross-platform comic and manga converter for Kindle, Kobo, reMarkable, and other E Ink readers. It processes image folders, comic archives such as CBZ and EPUB, and PDFs, then resizes pages to device profiles, crops margins and page numbers, adjusts contrast and black levels, supports manga and webtoon layouts, and detects or splits two-page spreads. It can produce MOBI/AZW3, EPUB/KEPUB, CBZ, PDF, or image-folder output, with GUI and command-line tools for Windows, macOS, and Linux. The project also includes processing intended to reduce the rainbow effect on Kaleido 3 displays using a 2D discrete Fourier transform. KCC is released under the ISC license and is maintained in the ciromattia/kcc GitHub repository.

Jevbox is a self-hostable, permission-aware document library from Extend for uploading, visually browsing, and inspecting parsed documents. It uses Extend for document parsing and stores parsed structures, heading outlines, source passages, and original files; supported viewers include PDF, DOCX, XLSX, PPTX, Markdown, code, JSON, CSV/TSV, images, archives, audio, and video, with a safe download fallback for unknown formats. Its JEV retrieval system performs permission-filtered hierarchical beam search across categories, documents, and sections, followed by usefulness scoring of source passages. Users can ask questions through the AI SDK or web chat, view inline citations and source previews, attach accessible documents to scope an answer, and connect through REST and MCP APIs. Uploads can be automatically filed by walking existing folders and validating model-proposed branches, while organization permissions are evaluated through SpiceDB. The repository supports local operation with Node, pnpm, Docker Compose, PostgreSQL, and SpiceDB, and provides Docker, Render, Helm, and AWS/EKS deployment options. It includes organization accounts, invitations, role-based sharing, durable background jobs, queued chat processing, and configurable model providers. Jevbox's original code is licensed under the MIT License; third-party code and assets retain their own licenses.
