If you play DnD, I would love feedback! Feel free to leave it as GitHub issues or discussion.
If you don't play DnD, you might still find the repo interesting. It's hono on bun, I render jsx server side and client side is all htmx. I use vercel's ai toolkit for the LLM interactions, which are super fun and work really well. I think this is a great use for AI actually. I've structured the code so the same services can be called either by the user via forms and routes, or via LLM tool use, so for every action in the code you can do it via either LLM or "manually".
