tempchat.cool vs Signal
Signal is the better choice for secure everyday messaging: it is open source and well audited. tempchat.cool is for the quick case where nobody wants to install an app or hand over a phone number, and the chat should delete itself afterwards.
Side by side
| tempchat.cool | Signal | |
|---|---|---|
| Needs an app | No, works in a browser | Yes |
| Needs a phone number to sign up | No | Yes |
| End-to-end encrypted | Yes | Yes |
| Open source and independently audited | Not yet | Yes |
| Lasts | Ends by itself after 1 to 36 hours | Until deleted; disappearing messages are optional |
| Forward secrecy | No | Yes |
| Calls, photos, voice | Text for now | Yes |
Be clear about the trade-off
Signal has years of public review and stronger protections, such as forward secrecy. tempchat.cool is a web app, so you trust the code we serve you each time. For anything where your life or work depends on it, use Signal.
Where tempchat.cool fits
- A one-off group with people who will not install anything.
