A self-hosted bookmarking app for links, notes, images and PDFs, with automatic AI tagging, full page archival and mobile clients.
Karakeep, previously called Hoarder, is a bookmark-everything app for people who save far more than they ever revisit. Links, quick notes, images and PDFs all land in the same place, and the pile stays usable because tagging and summarization happen automatically rather than waiting on your discipline.
The web app is built on Next.js with Drizzle for the database, tRPC between client and server, NextAuth for sign-in and Meilisearch for full content search. Puppeteer crawls saved links to pull titles, descriptions and images, and the tagging model can be a hosted provider or a local one served through Ollama.
Saving is only the first half of what it does.
- Full page archival: pages stored with monolith and videos with yt-dlp, so link rot cannot erase what you kept.
- Search: full text and semantic search over everything stored, including text pulled out of images by OCR.
- Capture everywhere: Chrome, Firefox and Safari extensions, iOS and Android apps, RSS hoarding and importers from Pocket, Linkwarden, Omnivore and Chrome.
- Rules engine: rule-based automation that files bookmarks without manual sorting.
- Collaboration: lists can be shared and worked on with other people.
A REST API and a command line client make the collection scriptable, and official agent skills let LLM agents work with it directly. Offline reading, highlights, bulk actions, SSO, dark mode and multi-language support are all present. Self-hosting comes first, under an AGPL-3.0 license, with a managed cloud for anyone who would rather not run it.
A self-hosted read-it-later service that saves web pages, strips the clutter and keeps your reading list on your own server.
wallabag is a web application for saving web pages to read later. Click, save, and come back when you have time. It extracts the article content so pop-ups and the rest of the page furniture do not follow you into the reading view.
Extraction quality is what decides whether a tool like this is worth keeping, and wallabag leans on three well-known libraries for it, Graby, php-readability and the ftr-site-config rule set. Site-specific configuration is what makes awkward pages come out clean.
Saved articles are reachable from more than the web interface.
- Android app: an official client maintained in its own repository.
- iOS app: likewise official and developed alongside the main project.
- Browser extension: wallabagger, for saving whatever page you are currently reading.
- GNOME app: read-it-later for Linux desktops, maintained outside the project.
Installation is a git clone followed by a make install, then a virtual host pointed at the result, with other methods documented for anyone who would rather not build from source. If running a server is not appealing, the maintainers operate a hosted instance you can sign up for instead.
Maintained since 2013 and distributed under the MIT license, the project takes translations through Weblate and welcomes anyone who wants to add a language. One request from the authors: the name is always lowercase.
