Here are standalone bookmark-management tools and apps that act like (or better than) Firefox’s built-in bookmarks manager — letting you organize, search, tag, and manage links outside of the browser itself:

📌 Desktop / Standalone Bookmark Managers

✅ Zotero

• A full-featured standalone desktop application for saving and organizing web pages, PDFs, and other resources.

• Originally a Firefox plugin, today it’s a cross-platform app (Windows, macOS, Linux) with a built-in library UI, tagging, searching, collections, and notes. Wikipedia

Why it might fit: Excellent for structured collections and research-style bookmarking (more robust than a simple browser bookmark UI).

✅ Raindrop.io

• A modern, cross-platform bookmark manager with apps for desktop and mobile, plus browser extensions.

• Supports folders/collections, tags, powerful search, multiple views, cloud sync, and even archive thumbnails. betterstacks.com+1

Why it might fit: Closest to a standalone app experience with a rich UI and organization features.

📍 BookmarkOS

• A standalone bookmark manager themed like a desktop interface — drag-and-drop, folders, quick search, etc. bookmarkos.com

Why it might fit: Feels a bit like managing files on your desktop, which some users prefer over a browser panel.

🛠 More Independent / Alternative Approaches

🖥️ buku

• A local, browser-independent bookmark manager (CLI + optional local web UI).

• Stored in a SQLite database; powerful search, import/export, flexible use. Reddit

Good if you want: A lightweight, portable, scriptable local bookmark database.

🗂️ TagSpaces

• A local file tagging and organization tool, not strictly a bookmark manager — but you can save URLs with tags and browse them like files. Wikipedia

Good if you want: Tag-centric local organization (bookmarks + files + notes in one place).

🌐 Web-based but Browser-independent (Useful if you want a central bookmark hub)

These aren’t desktop apps, but they’re standalone services with rich organization features:

• Pinboard – Minimalist, fast, tag-based bookmarking (web app, API). URL Magnet

• Papaly / Bookmark Ninja / Pinalist – Browser-independent bookmark dashboards. save.day

🧠 Notes & Tips

• Many users choose Raindrop.io as a hybrid solution (standalone apps + browser integration) if they want something more powerful than Chrome/Firefox bookmark panels. betterstacks.com

• Zotero is overkill if you only want bookmarks, but its standalone library and tagging/search features are unmatched for research workflows. Wikipedia

• Tools like buku are excellent if you don’t need a GUI and prefer local control with deep search and structure. Reddit

If you tell me your primary use case (e.g., simple folder/tag organization, research tasks, offline use, no cloud sync), I can narrow this down to the best choice for you.

Here are open-source bookmark managers and personal knowledge management (PKM) apps that are standalone (self-hostable or desktop/mobile) — perfect if you want something similar to Firefox’s bookmark manager but more powerful or integrated with a personal knowledge base (and importantly all open source):

🔗 Open-Source Bookmark Managers (Standalone / Self-Hosted)

These focus on saving, organizing, tagging, searching, and archiving bookmarks/links — often with web UIs and browser extensions.

1. Linkding

🗃️ A simple, self-hosted bookmark manager with tags, search, metadata fetching, and optional site archiving. Easy to deploy via Docker. linkding+1

2. LinkAce – Self‑Hosted Bookmark Archive

A clean open-source tool for archiving and organizing links into lists and tags, with a web interface and long-term link storage. LinkAce

3. Karakeep – Self‑Hosted Bookmark Everything App

More than a simple bookmark drawer — save links, notes, images, and full-page content; includes tagging, full-text search, AI-powered organization, and archiving. GitHub

4. Buku

A local (CLI + optional web UI) bookmark manager stored in SQLite. Great if you want power and scriptability with rich search and browser export/import. Reddit

5. Wallabag

Open-source read-it-later with article archiving, annotations, and a web UI. Not as full a bookmark manager as the others, but excellent for saving and retrieving web content over time. bookmarkos.com

6. Shaarli (from Self-Hosted Bookmark Lists)

A minimalist self-hosted bookmark list manager with simple tags and link storage. bookmarkos.com

7. SiteBar

Classic open-source online bookmark server you can self-host and access via a browser. Wikipedia

🧠 Open-Source Personal Knowledge Management (PKM) Tools

These are broader than bookmarks — they help you build a “second brain” with notes, links, interconnections, graphs, and metadata.

1. Logseq

A powerful local-first, open-source PKM and note-taking app with bidirectional links, graph view, tasks, and markdown/org-mode support. Excellent if you want to connect bookmarks with notes and ideas. Wikipedia

2. Lokus

Free and open-source PKM with markdown, wiki links, graph view, and infinite canvas — a modern take on building knowledge bases. Lokus

3. Zettlr

Markdown-centric note and knowledge manager that lets you organize files, tag them, link concepts, and create a research-style PKM. Wikipedia

4. SiYuan

A privacy-first open-source PKM tool with Markdown support and block linking — great for building a rich personal knowledge database. GitHub

5. Joplin (via alternatives tags)

Open-source note-taking with tags and sync, which can also be used to store bookmarks inside notes if structured properly. opensourcealternatives.to

6. TiddlyWiki

A unique single-file wiki you can use to build your own interconnected “knowledge web” including bookmarks as nodes. ferndesk.com

🧩 Combining Both Worlds

If you want a more integrated system where bookmarks become part of a deeper knowledge network:

• Logseq + Bookmark Plugins: Use a bookmark web clipper or manually import links into Logseq pages.

• Karakeep + Logseq/Zettlr: Use Karakeep to catalog links and then link or sync content into your PKM tool.

• Linkding + ArchiveBox: ArchiveBox can permanently save pages behind your Linkding bookmarks for long-term retrieval (open source). GitHub

📌 Which One to Choose?

For pure bookmarking:
✅ Linkding or LinkAce — simple and self-hosted
✅ Karakeep — rich with archiving and tags
✅ Buku — powerful CLI bookmark handling

For broad knowledge workflows:
💡 Logseq or Lokus — best if you want digging, interlinking, and graph-like connections
💡 Zettlr or SiYuan — heavier PKM with markdown and research features

If you tell me whether you want web-based, desktop, or self-hosted only, and how important notes & linking vs pure bookmarks is for you, I can narrow it to the best match for your workflow.

Here’s a bigger, updated list of open-source bookmark managers and personal knowledge management (PKM) tools — focusing on standalone, self-hosted, or privacy-friendly apps that can replace or extend Firefox’s bookmarks manager. selfhostedworld.com+1

🗃️ Summary by Category

📍 Bookmark-Focused

• Full-featured: Linkwarden, Karakeep, LinkAce

• Clean and modern: Servas, Backup Brain

• Minimal/Classic: Shiori, Shaarli, Buku, SiteBar, Scuttle

🧠 PKM & Knowledge Tools (Bookmarked + Notes)

• Logseq, Zettlr, TiddlyWiki, Joplin

⚙️ Complementary Tools

• Floccus (sync), SingleFile (archival), CLI helpers

If you want, I can group these by features (e.g., archiving, search, tags, notes integration) and recommend the best tools for your specific workflow (e.g., research focus vs simple bookmarking).

Short honest answer: no — but you’re now very, very close to the edge of the map. 😄
Long honest answer: there is no finite “all” here, because this space includes decades of abandoned, niche, academic, CLI-only, single-dev, and experimental projects. What I can do is push into the deep cuts — the stuff most lists stop mentioning.

Below is the “you asked for everything” tier: obscure, old, weird, researchy, CLI-only, wiki-based, or semi-forgotten open-source projects that still count as bookmark managers or PKM systems.

🧨 Ultra-Obscure / Deep-Cut Bookmark Managers

These rarely show up in “top X” lists anymore.

• Espial – Haskell-based bookmark server (very niche, very hackerish)

• Briefkasten – Minimal self-hosted bookmarking app

• Bort – Rust-based bookmark manager (early / experimental)

• Linksort – Tiny self-hosted bookmarking service

• Neonlink – Personal link manager (low-traffic GitHub project)

• Booky – Lightweight web bookmark app (multiple abandoned forks exist)

• Slash (various forks) – Hacker-news-style personal link storage

• Unmark (OSS server, client discontinued)

• Pebbles – Extremely minimal bookmarking backend

• Grimoire / Gnosis-style bookmark DBs – Wiki-like link catalogs

Many of these live only on GitHub with <100 stars and no website.

🧰 CLI / Terminal-First Bookmark & Knowledge Tools

For people who think GUIs are optional:

• buku – The gold standard CLI bookmark manager

• papis – Research & reference manager (URLs + metadata)

• org-mode (Emacs) – With org-roam, org-ref, org-web-tools

• nb (nota bene) – CLI notes + bookmarks + knowledge base

• jrnl – Journaling tool often repurposed as PKM

• taskwarrior + annotations – Links embedded in task metadata

• zim-wiki (CLI + GUI hybrid) – Personal desktop wiki

🧠 Wiki-Based & Knowledge-Base Systems (Often Used for Bookmarks)

These technically aren’t “bookmark managers,” but many people use them exactly that way:

• DokuWiki

• MediaWiki

• PmWiki

• Zim Wiki

• Foswiki

• XWiki

• Ikiwiki

• Dokuwiki + link plugins

These let you build manual but powerful link taxonomies.

🧪 Research / Academic / Experimental PKM

Less mainstream, more “knowledge science” vibes:

• Athens Research (open-core, graph-based)

• Memex projects (multiple OSS academic attempts)

• Hypothes.is (open annotation layer; bookmarks via highlights)

• Roam-inspired OSS clones (many short-lived)

• Knowledge Graph personal systems (RDF/semantic-web based)

🗃️ Archival-First (Bookmarks + Permanent Storage)

Often paired with bookmark managers:

• ArchiveBox

• SingleFile

• Webrecorder / ArchiveWeb.page

• Perkeep (archival + bookmarks)

• Wallabag

• Monolith

These treat bookmarks as pointers to preserved artifacts.

🧬 File-Based PKM (Links as First-Class Citizens)

• Logseq

• Zettlr

• Trilium

• SiYuan

• TiddlyWiki

• Foam

• Plain Markdown + ripgrep

• Nextcloud Notes + Bookmarks

🧠 Reality Check (Important)

There is no canonical registry of:

• abandoned GitHub bookmark projects

• personal one-off tools

• forks that only differ by UI

• scripts people quietly use for years

If someone claims they’ve listed everything, they’re lying — or defining “everything” very narrowly.

What does exist:

• “awesome-selfhosted” lists

• GitHub topic searches (topic:bookmark-manager)

• Reddit archaeology

• personal dotfiles

And you’ve now essentially exhausted those.

🧭 If you want, we can go further — but it becomes targeted:

I can:

• list only local-first (no server) tools

• list only GUI desktop apps

• list only CLI tools

• list only actively maintained projects

• map tools closest to Firefox’s bookmark UI

• help you build your own minimal bookmark manager (SQLite + UI)

At this point, the question isn’t “what else exists?”
It’s “what exact shape of tool are you actually hunting for?” 👀

Absolutely — here are actual links and websites for many of the lesser-known and timestamped open-source bookmark managers and related tools, including obscure ones where available. I’m also including a few things that we know exist on GitHub even if they don’t have a dedicated website.
