The Seafile plugin enables seamless synchronization of Obsidian notes across multiple devices using Seafile, a high-performance, self-hosted file syncing solution. The plugin integrates Seafile's syncing API, allowing users to efficiently sync their notes and manage repositories. It supports both desktop and mobile platforms, ensuring smooth synchronization even on low-end Android devices. The plugin also allows users to specify files to ignore, ensuring greater control over the sync process. However, it currently does not support encrypted repositories and may encounter issues with large files. Overall, it provides an effective way to keep Obsidian data synchronized, though users should exercise caution to prevent data loss or corruption.

The sync-db-os plugin streamlines file synchronization in Obsidian by automatically uploading local images to specified object storage and updating their links. It also facilitates the resolution of conflicts between notes edited on multiple devices and supports uploading large files like PDFs while storing only their hash values in the database. Designed to optimize database usage, the plugin integrates with MongoDB and CouchDB, and supports major object storage providers such as Tencent Cloud and Alibaba Cloud. Key features include automatic image uploads, manual conflict resolution, and efficient large file management.
