Whodunit started as a pen-and-paper game for family game night. It evolved into a web app with a new mystery every day.

The mysteries are all written by LLMs. Some are better than others, but most work nicely.

The web app is written in go with templ HTML templates, HTMX for on-page interactivity, SSE for content updates, and a turn-based game engine written as a Temporal workflow.
