Zotero Style is a Zotero add-on that adds an Ethereal-style interface and extends Zotero's item columns, tags, views, ratings, and PDF-related features. It modifies existing columns and adds columns for reading progress, annotation word count, read status, tags, rendered tags, and publication rankings based on configurable journal-ranking datasets. The add-on supports nested tags using category/subcategory syntax, customizable tag mappings with strings or regular expressions, saved view groups, quick filtering by item type, and a graph view for visually locating related Zotero items. It also provides a rating control, editable PDF styles, and a PDF reading-progress visualization whose title background reflects per-page reading time. The repository provides downloadable XPI packages and documents updates through Zotero's add-on update mechanism.

Syncular is an offline-first SQL synchronization toolkit that keeps an SQLite database on each client while treating a server-owned commit log as authoritative. Applications read and write local SQLite immediately; writes enter an outbox and are checked and reconciled by the server during synchronization. The browser client runs SQLite on OPFS, while native integrations share a Rust core with native SQLite through bindings for Rust, Swift, Kotlin, Flutter, React Native, and Tauri. Servers can run on Bun, Node, or Cloudflare Workers with SQLite, Postgres, or D1. The project also provides server-side persistent SyncClients, database-less SyncRemoteClients, schema and query code generation, React hooks, column encryption, Yjs CRDT integration, and TypeScript and Rust implementations checked against a shared conformance catalog. Syncular is maintained by Benjamin Kniffler and is pre-1.0; its public APIs and protocol details may change before 1.0. The repository is released under the license stated in its repository files.

Open Archiver is a self-hosted, open-source platform for archiving, storing, indexing, and searching email from Google Workspace, Microsoft 365, IMAP inboxes, PST files, zipped EML files, and Mbox files. It supports bulk imports and ongoing synchronization, and provides full-text search across messages and attachments with filters and thread discovery. Messages are stored as standard EML files with deduplication, compression, and encryption at rest. Storage can use a local filesystem or an S3-compatible object store. The system records file hashes during ingestion and provides integrity reports, retention policies, and an immutable audit trail for access and activity tracking. The platform is deployed with Docker Compose and uses SvelteKit, Node.js with Express and TypeScript, BullMQ with Redis or Valkey for asynchronous jobs, Meilisearch for indexing, and PostgreSQL for metadata, users, and audit logs.

Zerobyte is a self-hosted backup automation tool for managing encrypted backups of local and remote storage. Built on Restic, it provides a web interface for scheduling, monitoring, retaining, browsing, and restoring backup snapshots across local directories and NFS, SMB, WebDAV, and SFTP sources, with storage backends such as local and cloud destinations through Rclone. It supports compression, end-to-end encryption, and fine-grained retention policies. Zerobyte is distributed as a Docker container and requires Docker and Docker Compose. Its documentation warns that the 0.x series is subject to major changes and recommends protecting internet-accessible deployments with a secure tunnel and authentication.

BookOrbit is a self-hosted library and reading platform for ebooks, PDFs, audiobooks, and comics. It provides web readers and synchronizes reading progress, highlights, annotations, and reading status between BookOrbit, Kobo devices, and KOReader. The platform includes library management with metadata enrichment, multiple libraries, collections and rule-based saved filters, multi-user accounts with OIDC/SSO, OPDS access, Send-to-Kindle delivery, and browser uploads. It also provides reading statistics, goals, achievements, searchable annotation exports, and synchronization with services including Hardcover, Readwise, and StoryGraph. The project is designed to run on infrastructure controlled by the operator.
