LeetJump

LeetJump is a browser extension designed to streamline navigation and search for LeetCode problems, catering to developers practicing algorithms and data structures. The tool enables instant access to over 3,000 LeetCode problems through a universal Alt+L keyboard shortcut, aiming to help users maintain momentum during coding practice.

Key features include real-time search with response times under 150 milliseconds, debounced search, and intelligent result ranking. Users can search by problem number, title, or keyword, and employ slash commands such as /potd for quick access to the Problem of the Day. The extension leverages local storage only, with IndexedDB caching and a 24-hour cache staleness policy, supporting offline fallback for continued use without an internet connection. Background synchronization occurs every six hours, and the tool displays rich metadata, including difficulty indicators.

LeetJump is available for Chrome, Chromium-based browsers like Edge, and Firefox, with installation options through the Chrome Web Store, Firefox Add-ons, or manual installation for developers seeking the latest features. The extension emphasizes privacy by storing data locally, requiring minimal browser permissions, and operating without tracking or analytics.

The tool is free and open source, requiring no registration to use. It is developed by lirena00 and encourages community involvement through financial or non-financial support such as starring the GitHub repository, sharing with peers, or providing feedback.
