How to Add LeetCode Stats to Your GitHub Profile README

The leetcode-stats card displays your total problems solved broken down by difficulty (Easy/Medium/Hard), your global ranking, acceptance rate, and contribution points — all in a compact SVG card. It reads your data from LeetCode's public API using just your username, with no authentication required on your end.

LeetCode stats are particularly valuable to include if you are targeting roles in competitive technology companies where algorithm interviews are standard (FAANG, trading firms, competitive programming-adjacent roles). For other roles, the stats are a positive signal but carry less weight than demonstrated project work.

Add this to your README, replacing YOUR_LEETCODE_USERNAME:

![LeetCode Stats](https://leetcard.jacoblin.cool/YOUR_LEETCODE_USERNAME?theme=dark&font=Karma&ext=activity)

Alternative service (KnlnKS/leetcode-stats):

![LeetCode Stats](https://leetcode-stats-six.vercel.app/api?username=YOUR_LEETCODE_USERNAME&theme=dark)

Key parameters for the jacoblin.cool service:

• theme: dark, light, nord, forest, unicorn
• font: Any Google Font name (e.g., Karma, Baloo_2, Nunito)
• ext: activity (adds a recent activity chart), heatmap (adds a submission heatmap), contest (adds contest rating history)
• border: Set to 0 to remove the card border
• animation: Set to 0 to disable card entrance animation

For a card that matches your GitHub profile theme, use:

• Dark profiles: theme=dark or theme=nord
• Light profiles: theme=light or theme=forest

The ext=activity parameter adds a recent submission chart showing your problem-solving frequency over the past few months. This is a strong addition if you practice consistently — it shows not just total numbers but recent engagement.

For a more compact layout, you can link the card to your LeetCode profile page:

[![LeetCode Stats](https://leetcard.jacoblin.cool/YOUR_USERNAME?theme=dark)](https://leetcode.com/YOUR_USERNAME)

Position the LeetCode card alongside other credential stats — Stack Overflow reputation, GitHub stats — for a credibility-focused stats row in your profile.

If the card shows an error or 'User not found', verify your LeetCode username is spelled exactly as it appears on your profile page (case-sensitive). If you recently created your account, LeetCode's API may take a few days to return data — new accounts with very few submissions may show zero counts.

If the card loads but shows stale data, LeetCode's public API has rate limits and the service caches results. The cache typically expires within a few hours and refreshes automatically.

For accounts with a private LeetCode profile, the public API may not return all statistics. Check your LeetCode privacy settings — under Account Settings → Privacy → Profile → make sure your 'Solution count' is set to public for the full card to render correctly.
