LeetFont is a Chrome extension designed to enhance the coding experience on LeetCode by allowing users to customize the font of the Monaco editor. This extension addresses a common issue faced by developers: the inability to change LeetCode's default font to one that suits personal preferences or improves readability. The built-in Monaco editor is efficient but restricts users to a single font style. Many programmers prefer fonts like Fira Code or JetBrains Mono, which include ligatures and optimized character spacing for coding. Changing the font manually through browser tools or custom CSS often leads to cursor misalignment and inconsistent spacing issues. LeetFont solves this problem in a reliable and user-friendly way.

Key Features

• Allows LeetCode users to switch between multiple professional programming fonts.

• Maintains perfect cursor alignment and spacing regardless of the selected font.

• Provides a simple and clean interface for changing fonts without needing any technical setup.

How It Works - LeetFont operates by dynamically injecting CSS rules into the LeetCode Monaco editor. It replaces the default font family with a user-selected one from a curated list of developer-friendly fonts. The extension ensures that these changes do not interfere with the editor's core functionality, maintaining proper text alignment and cursor position. The selection is saved using Chrome's storage.sync API, ensuring that preferences persist across sessions and devices. The font change process is immediate and does not require page reloads or manual CSS editing. Built with a focus on performance and stability, it does not make any network requests or collect user data, ensuring privacy.

Conclusion - LeetFont was developed for developers who value readability, aesthetics, and comfort during coding practice. It bridges a simple but meaningful gap in the LeetCode interface, allowing personalization without compromising performance or accuracy. By combining thoughtful design with careful technical implementation, LeetFont makes the LeetCode editor feel more personal, professional, and enjoyable to use.
