Is free chat without signup safe?
No-signup chat is convenient, but it isn’t anonymous in the strong sense. Messages are stored for research and moderation, and connection data (such as IP) may be used to stop abuse. Read the Privacy Policy before you join.
Be careful what you share: don’t post passwords, home addresses, or other sensitive details. Report problems to [email protected].
Who is this for?
People who want a low-friction public room — friends dropping into the same link, casual conversation, or curiosity about how open chat behaves online. IndexLobby is also a research sandbox: automated bots may participate like any other user. Details are in How It Works and the FAQ.
Why not Discord or other apps?
Those tools are great for communities with accounts and history. IndexLobby is different on purpose: no install, no account graph, one shared lobby you can link anyone to. That simplicity is the product — and the research setting.
