Leetify For Cses

# Leetify for CSES

## Turn CSES into a modern competitive programming workspace.

CSES is one of the best collections of algorithm and data structure problems for competitive programming—but its interface hasn't changed much over the years. **Leetify for CSES** transforms the familiar CSES experience into a modern, distraction-free workspace inspired by the best coding platforms, without changing how CSES works.

Enjoy a resizable split-pane layout, a VS Code-powered Monaco editor, automatic code saving, dark mode, and a streamlined workflow—all directly on **cses.fi**.

No accounts. No setup. No third-party website. Just a better way to solve CSES problems.

## Why Leetify for CSES?

If you regularly practice on platforms like LeetCode, Codeforces, or AtCoder, switching back to CSES can feel limiting. The default editor is minimal, progress can be interrupted, and managing test cases often means juggling multiple windows or external editors.

Leetify for CSES brings the productivity features you expect from a modern coding environment while preserving everything you already like about CSES.

Most importantly, **it doesn't replace CSES—it enhances it.**

Your account remains your CSES account.
Your submissions still go through CSES.
Disable the extension, and the original website is instantly restored.
