No Cap – Coding Integrity Tracker

About

No Cap is a productivity and self-improvement extension designed to encourage honest coding practice on LeetCode.

Instead of restricting users or modifying coding platforms, No Cap helps developers build discipline by tracking coding behavior during practice sessions and presenting transparent integrity metrics.

Key Features

• Tracks coding sessions on supported LeetCode problem pages
• Detects copy and paste events during practice
• Generates an Integrity Score based on coding behavior
• Displays live session statistics through an intuitive popup
• Maintains local session history and performance trends
• Helps users identify improvement areas and reduce reliance on external solutions
• Lightweight design with minimal performance impact
• Works entirely inside the browser without interfering with LeetCode functionality

Privacy First

No Cap does not collect, transmit, or sell personal information.

All integrity calculations and activity tracking occur locally inside the user's browser.

The extension does not access account credentials, passwords, private messages, or unrelated browsing activity.

Permissions

The requested permissions are only used to enable functionality such as monitoring supported LeetCode pages, storing session statistics locally, and displaying the extension interface.

Who is this for?

• Students preparing for technical interviews
• Competitive programmers
• Developers building consistent coding habits
• Anyone who wants to practice coding honestly and measure personal progress
