Show HN: Public todo lists – no accounts, just a secret key you save once (publictodo.com)

Most todo apps want your email. I wanted something you could use in 10 seconds and share publicly.

Create a list, get a URL like publictodo.com/yourname, save a one-time key in your password manager. No account, no email, no OAuth.

Built with vanilla JS and Supabase. I see people using this for public project roadmaps, AI agent task lists, or personal accountability. Knowing a list is public has a way of making you actually finish things.
