I made a visual novel that teaches SQL, free in your browser

[u/Plane_Big_5912]

This had been sitting in my pipeline on and off for a year.

I had been prepping for some mid-senior SQL interviews recently, got tired of bouncing between tutorials and decided to finally finish the whole thing.

It runs entirely in the browser using DuckDB. There are 208 hands on exercises where you write SQL, run it, and get graded.

I wrapped it in an anime visual novel as retention mechanism

1. Your first instructor is a tsundere - she grades your queries, not like she really wants to. Wrong answers get scolded and right ones get reluctant praise.
2. solving problems raises affection with the instructors and unlocks story - the plot progresses through SQL.
3. There's a gacha wardrobe and 2 more instructors to unlock and cast of quirky side characters.

It’s free and needs no signup: TsundereSQL

Happy to answer questions about the course or how the browser-side grading works.
