Diigo vs Shiori

Diigo is a personal knowledge-management tool for collecting, annotating, and organizing web material. While browsing on a computer, tablet, or phone, users can mark pages with highlights and sticky notes, then save links, pages, notes, and pictures in a cloud library. Saved pages can be archived and searched in full text. Groups can maintain shared repositories where members browse material and interact with page annotations. Diigo also supports saving items from social media, capturing links and notes by email, importing bookmarks from browsers, Delicious, or Pinboard, and exporting libraries and annotated PDFs. Its listed services include an API, blog auto-publishing, tagrolls, and linkrolls. Diigo offers a browser extension, apps for Android and iOS, and Quick Note on Mac. The free plan allows 1,000 bookmarks or notes and 200 highlights, but has limits on other items and groups. Paid plans are Standard at $5 a month and Professional at $6 a month. Diigo says browsing history is not recorded except for pages specifically bookmarked to its servers.

Shiori is a free, Go-based bookmark manager that can be used from the command line or as a web application. It supports adding, editing, deleting, and searching bookmarks, and can import from Pocket or Netscape Bookmark files. Export is available in Netscape Bookmark format. Where possible, it parses readable page content by default; users can also create offline webpage archives and ePub ebooks. The project documents SQLite3, PostgreSQL, and MySQL support. It is self-hosted and offered as a single binary under the MIT license, which permits use and modification. Installation options include precompiled binaries, source builds, and Docker images, with instructions for Windows, Linux, and macOS. Beta web extensions are described for Firefox and Chrome. Shiori is listed at free. Its documented API v1 is still under development, and the project warns that breaking changes may happen before release. Contributions through pull requests are welcomed, including contributions to community-provided installation methods.
