Blarb

Frequently Asked Questions

What is Blarb?

Blarb is a simple, frictionless web chat. Just open any URL ending with /:channel, share it with friends, and start chatting instantly — no registration or setup required.

Do I need to sign up or log in?

No. Blarb doesn’t require signups, logins, or passwords. Just create or join a channel with a URL.

How do channels work?

Any URL path becomes a chat channel. For example:

  • blarb.com/test
  • blarb.com/channel-name

Share the link, and anyone who opens it joins the same chat.

Features

What kind of chat does Blarb support?

  • Real-time text chat
  • Unlimited participants per channel
  • Push notifications (for non-P2P channels)
  • Message history stored for 24 hours

Can I protect my channel with a password?

No. But you can create a private space by using a hard-to-guess channel name (e.g. /friends-4h3jd9x).

How long are messages stored?

Messages are kept on the server for 24 hours in regular channels. P2P channels don’t store messages at all.

What’s a P2P channel?

Add @ in front of a channel name (e.g., /@private-chat) to create a peer-to-peer channel. In these channels:

  • Messages are sent directly via WebRTC mesh (never touch Blarb’s server).
  • No message storage.
  • Push notifications are not supported.

Can I embed a channel into my website?

Yes. Channels can be embedded inside an <iframe> for seamless integration.

Technical & API

Does Blarb have an API?

Yes, Blarb provides two simple endpoints: API docs

Are there limits on API usage?

Use the API responsibly. Abusive behavior will result in immediate rate-limiting or blocking.

Privacy & Security

Is my data secure?

Yes. Blarb uses secure connections (HTTPS). In regular channels, messages are stored temporarily (24h). In P2P channels, messages never go through our server.

Can I delete messages?

Messages automatically expire after 24 hours in regular channels. In P2P channels, messages are never stored anywhere by design.
