AlgoLens is a privacy-first browser extension designed for LeetCode enthusiasts. It automatically tracks your solving metrics (time spent, attempts, difficulty levels), syncs your clean solution code to a dedicated GitHub repository, and generates beautiful, dynamic analytics cards to showcase on your GitHub profile.
- 🔄 Instant GitHub Sync: Automatically pushes your accepted LeetCode solutions directly to your configured GitHub repository in real-time.
- ⏱️ Smart Focus Timer: Tracks the active time you spend solving a problem. It automatically pauses if you switch tabs or leave your keyboard, ensuring precise telemetry.
- 📊 Dynamic Profile Cards: Generates elegant, real-time SVG statistics cards and streak counters to display on your GitHub profile README.
- 🔒 Privacy-First Design: Your GitHub Personal Access Token (PAT) is stored securely in your browser's local sandboxed storage. It never leaves your machine and is never sent to our telemetry backend.
- 📈 Global Benchmarks: Anonymously aggregates solving speeds and attempt counts to compare your performance against global community benchmarks.
To allow AlgoLens to sync solutions directly to your repository:
- Go to GitHub Settings -> Developer Settings -> Personal Access Tokens -> Tokens (classic).
- Click Generate new token (classic).
- Provide a note (e.g.,
AlgoLens Sync) and select thereposcope checkbox. (This is required for the extension to push files to your repository). - Click Generate token and copy it securely.
- Open the AlgoLens extension popup in your browser, navigate to the GitHub Sync tab, and paste your token.
- Select your target repository and the subfolder name where you want solutions to be stored (e.g.,
leetcode).
Once configured, simply solve LeetCode problems as you normally do.
- The smart timer automatically begins tracking as soon as you open a problem.
- When you click Submit and get an
Acceptedstatus, AlgoLens captures your code, attempt count, and duration. - Your code is instantly pushed to your GitHub repository, and anonymous statistics are updated.
You can embed your dynamic AlgoLens card on your GitHub profile README. In your solutions repository, AlgoLens automatically configures a README with the following structure:
<!-- algolens:start -->
<!-- algolens:end -->The metrics block and SVG benchmarking cards will automatically populate between these comments!
If you want to run the telemetry backend locally, host it on your own server (e.g., Render, NeonDB), or compile the Chrome Extension from source, please refer to the DEPLOYMENT_GUIDE.md.
