Provides a browser-native way to quickly save and organize web content into Karakeep, an open-source bookmark/link manager, without leaving the current page

User installs extension and configures their Karakeep instance URL and API key in options. When browsing, user clicks the extension icon (or uses Ctrl+Shift+E) to save the current page URL. Can also right-click links, selected text, or images to save them. Extension sends the bookmark data to the Karakeep API. Badge on the extension icon shows green if the current page is already bookmarked. User can click context menu to open Karakeep dashboard or view the bookmark directly.

Target users: Users of Karakeep open-source bookmark manager / Self-hosting enthusiasts who manage their own bookmark service / Users who want a privacy-focused bookmarking solution

Code is heavily minified, making detailed analysis of UI flows difficult
Cannot fully inspect the options page UI for login/API key configuration flow
SingleFile content script is very large (800KB) and contains public suffix list data unrelated to core functionality

Monetization

No paid features detected

No evidence of payment integration, billing APIs, subscription checks, or feature gating within the extension code. The 'subscribe' keyword found is from React Query's internal state management subscribe() method, not a billing subscription. 'pro' matches are from minified variable names (profiler, process, etc.) and library code. 'license' matches are React library MIT license headers. The extension is open-source (GitHub support URL). While karakeep.app cloud service may have its own business plans, the extension itself does not gate any features behind payment.

Confidence: 80
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension requires an API key configured in its options to authenticate with a Karakeep instance. The background script checks for both 'address' and 'apiKey' - if either is missing, the API client is removed and functionality is disabled. The API key is sent as a Bearer token in Authorization headers to the Karakeep tRPC API endpoint. Users must have an account on a Karakeep instance (self-hosted or cloud.karakeep.app) to obtain the API key.
