Karakeep
An open-source extension that bookmarks links to your Karakeep app.
Why it's a strong pick
Karakeep's extension is a small, focused tool for saving links to the Karakeep app, which you can self-host. It is open source under AGPL-3.0, and its code is public on GitHub. It uses Manifest V3, Chrome's current extension format. The repo was updated in September 2026. Host access is optional, so the extension asks for it when it needs it.
What it does
The extension bookmarks links to Karakeep. Karakeep describes itself as a self-hostable app for bookmarking everything. You install the extension, point it at your Karakeep server, and save the page you are on. The README says the Chrome plugin, Firefox add-on and Safari extension are for quick bookmarking.
Key features
- Quick bookmarking. Save the current page to Karakeep.
- Right-click menu. The manifest includes context menus.
- Optional site access. Host permission is requested on demand.
- Open source. The code is public under AGPL-3.0.
- Other browsers. The README also lists a Firefox add-on and a Safari extension.
Who it's for
Karakeep's extension is for people who run or use Karakeep and want one-click saving from the browser. It suits self-hosters. The extension itself is not sold, but it does nothing without a Karakeep server to connect to.
What permissions does Karakeep ask for?
Its manifest asks for storage, tabs, contextMenus, activeTab and scripting. Access to all sites is optional, so Chrome can ask for it later instead of at install. Its content script is limited to a placeholder address, https://karakeep.invalid/*. Read each permission prompt when it appears.
Do I need a Karakeep server?
Yes. The extension saves to a Karakeep server, so you need one to connect to. The app is self-hostable. Set up the server first, then add the extension and enter your server address. Without a server, the extension has nowhere to save links.
What about privacy?
We could not read the developer's privacy policy when we checked; read it before installing. The extension saves links to the Karakeep server you connect it to, so where your bookmarks end up depends on that server and who runs it.
FAQ
Is it open source? Yes. The repo is licensed AGPL-3.0.
Why does it ask for permission later? Site access is optional in the manifest, so Chrome may prompt you when a feature needs it.
Does it work without a server? No. It needs a Karakeep server.
Good to know
Because site access is optional, a save can trigger a permission prompt. Allow it only if you are happy with it. Tagging and search belong to the Karakeep app, not the extension, and we did not check how they work, so look at the app before you commit. If you want normal browser bookmarks synced as well, Floccus lists Karakeep as a backend.
