[showoff Saturday] I got hooked on Advent of Code and wanted it all year, so I built a site that gives everyone the same coding challenge every day

Every December I do Advent of Code and every January I try to keep the habit going on LeetCode. Never lasted more than a week. Too many problems, no reason to do this one today.

So I borrowed the idea and built Daily Coding: one challenge a day, the same for everyone, all year. You solve it in the browser, hit run, and the tests execute in a sandbox in well under a second. 11 languages so far (JS, TS, Python, PHP, Ruby, Java, Go, C++, C#, Rust, Swift). Once you submit you can read everyone else's solutions, which for me was always the best part of AoC. Streaks and a leaderboard if you like that sort of thing.

Some honest numbers: I started in January, 7 months of evenings, about 470 commits. There are 40 challenges right now, so the rotation repeats after 40 days until I add more. Someone on Discord asked for Swift last week, that took a day to add because the sandbox already had it.

It's free, non-profit, open source under MIT. You can solve today's challenge without an account, signing up is only for streaks and rankings.

What I'd love to know: does one challenge a day work for you, or do you want to pick? And what would make you stop after a week?
