Show HN: Blarb – Chat instantly, just by sharing a link

I built blarb.net as a way to start a chatroom instantly, without accounts or installs. Any URL is a channel — for example, blarb.net/anything becomes a live room you can share.

Some features:

- No signup — just share a link

- Peer-to-peer channels with end-to-end encryption (/@channel-name)

- 24-hour history (regular channels auto-expire)

- Unlimited participants

- Embeddable on your site or blog

- Free to use

Would love feedback from the HN community.
