Show HN: Spotify Wrapped but for LeetCode

Show HN: Spotify Wrapped but for LeetCode(github.com)

Do people use LeetCode all year round? I thought it was something people fresh out of school did because they thought it helped them be better at FANG interviews, but seems I've missed how they seemingly grew in scope.

> I was hesitant to implement this because I obviously people wouldn't trust inputting a cookie into a form, but if this repo gets lots of stars I'll make a chrome extension that gets around this.

Fun how it goes the opposite compared to the real security implications. Sending one exact cookie you can see to one site VS giving an unknown entity access to * permissions on your computer, and the entity can change at any time + update in the background by their own wishes.

Yup, it’s essentially a daily habit for many devs these days, I think they've added more gamification (streaks, badges, contests) combined with a UI update that makes it feel less like "prep." (example: https://leetcode.com/quest/)

You're spot on, it is pretty interesting. I suggested the extension purely to bridge that trust gap, especially if it's verified by the Chrome Web Store. If the extension is designed to strictly avoid calling any external APIs (other than leetcode graphql), it makes exfiltration impossible, ensuring the cookie never leaves the user's browser

Beyond students/juniors? I don't think I've ever seen any of my colleagues or friends either talk about it or using it recreationally, but maybe I live in a different bubble.

They need to keep practicing FANG interviews because they switch companies

Leetcode already has a feature like this, it just hasn't released for 2025 yet. Usually comes out closer to the end of the year.

Here is last years: https://leetcode.com/rewind/2024/

The OPs seems to be more cumulative lifetime stats rather than just this past year, for a lot of the slides.

That's interesting, didn't know that. Bummer you can't replay it once "the event has ended."

I disclose that the last 5 slides are lifetime stats in my readme:

"Note: The last 5 slides are not necessarily specific to 2025 because of leetcode's graphql api only allows querying up to 20 of the latest submissions from an unauthenticated user.

However, if you pass a LEETCODE_SESSION cookie (obtained from leetcode.com, open dev tools -> application -> cookies) with your request you can query all of your accounts submissions. You could also use the calendar endpoint query all of your submissions in the past year, and thus create a much more nuanced leetcode wrapped. (ex: You struggled with this problem the most in 2025.)"

I may try to tackle this via an extension with no server side logic if I have some free time later this week, would certainly be a cooler final product. Only caveat is users would have to manually install the extension from a github repo (too scary for most people) or the chrome web store, which may add too much friction for most people.
