You get 32 tokens as a guest, one back every 5 min. So you can't draw much on your own - the thing only fills if people show up. That's the point, hence the name (monophobie = fear of being alone).
Always wanted my site to have a wall where people could leave me messages, and I've always loved r/place. So I started wondering what it'd take to build my own version. This is it.
Stack: TanStack Start + TanStack Virtual, had to virtualize the grid or it chokes on mobile. Postgres holds the canvas, Redis the token buckets, BullMQ for [what it actually does]. Better-Auth with optional passkeys, but guests draw right away, no signup.
