A commitment tool for developers. DevGuard locks down web traffic on your browser and redirects you to the daily LeetCode challenge, lifting the block only after you successfully solve it.
DevGuard
ID: bchpghhkgmldknidphbgnfcfjlkfomle
Make yourself more productive. Restricts browser access until you solve the daily LeetCode challenge. Built with Declarative Net Request rules.
Core Features
DevGuard is designed with zero bloat to strictly keep you on track. Here's the core system under the hood.
DNR Blocker Engine
Utilizes Chrome's Declarative Net Request API to redirect main-frame browser requests. Bypassing it requires resolving the daily challenge, closing the loophole.
Automated API Verifier
Connects query payloads with the LeetCode API to monitor your username status. The moment you achieve an 'Accepted' daily solution, permissions are automatically restored.
Local Session Isolation
No servers, no web logins, and no trackers. All configuration and redirection states are saved locally in the browser storage, keeping your credentials 100% private.
Gamified Streak Tracker
Features an embedded analytics layer that counts the total number of consecutive daily problems solved through the extension, helping you build habit loops.
