Comparison
FadeChats vs Signal: chat without registering a number
Signal needs a phone number to sign up, even if a username later hides it from the people you talk to. FadeChats needs no sign-up at all: open a room in your browser and send a link. One is built for contacts you keep, the other for a single conversation.

Signal is designed around identity: a phone number anchors your account, contacts see you the same way every time, and message history can persist across devices if you let it. Since 2024 a username can keep that number out of view, but Signal still holds it, and you can't register without one.
FadeChats is designed around the opposite assumption: two people who may never talk again, who'd rather not exchange phone numbers or add each other as contacts, and who want the entire exchange to vanish when it's done.
The trade-off runs the other way on your IP address. Every Signal message passes through Signal's servers, so the person you're talking to never learns where you're connecting from. FadeChats usually links the two browsers directly, which keeps messages off any server but lets each side see the other's IP. Only when a direct path is blocked does the chat go through a relay server. If the other person must not learn your IP, Signal is the safer pick.
Side by side
| FadeChats | Signal | |
|---|---|---|
| Phone number required | No | Yes |
| App install required | No — runs in the browser | Yes |
| Disappearing by default | Yes — every room | Off by default; a timer can be set for all new chats |
| Group support | No — always exactly two people | Yes |
| Ongoing message history | No — nothing persists after the room | Yes, if you keep it |
| Anonymity between parties | No number or account, but the direct connection shows your IP to the other side | Number required to register, can be hidden behind a username; messages go through Signal's servers, so contacts don't see your IP (calls only with 'Always relay calls' on) |

When to use which
- Use Signal: a contact you'll message again
Family, close friends, a recurring work relationship — Signal's identity-anchored model and message history are features here, not drawbacks.
- Use Signal: group conversations
FadeChats is strictly two people by design. For a group thread, Signal is the tool.
- Use FadeChats: neither side wants to sign up
No phone number, no email, no account on either end, so there's nothing to hide behind a username in the first place.
- Use FadeChats: a one-off exchange with a stranger
Buying something secondhand, coordinating with someone you just met, a support conversation — situations where adding a contact feels like the wrong move.
How FadeChats works
- Skip the install
FadeChats runs entirely in the browser. Loading the page is the whole setup — no app store, no registration, no phone number.
- Send a link, not your number
Share the one-time invite over any channel you already use. The other person taps it and joins — no contact is added on either side.
- Talk, close the tab, vanish
Messages usually go directly between your two browsers, and they are never stored on a server. The room closes on its own after about ten minutes of inactivity. The other person can still take a screenshot.
Where a Signal username stops helping
A Signal username hides your number from the person you're talking to, and often that's enough. It doesn't help when the other person isn't on Signal, or won't install an app and register a number just to talk to you once. That's the gap FadeChats fills: you both open a link in a browser, and neither of you signs up for anything.
Frequently asked questions
Is FadeChats more private than Signal?
It depends on the threat model. Signal has stronger cryptographic guarantees for ongoing, high-stakes conversations. FadeChats minimizes identity exposure and persistence for one-off chats — no phone number, no account, no history. Different kinds of private.
Why does Signal need my phone number?
Signal uses your phone number to anchor your account and let contacts find you reliably. It's a deliberate design choice for a persistent identity, not a shortcut.
What can I send in FadeChats compared with Signal?
Text, images, GIFs and stickers. Signal does more: files, voice messages, and voice and video calls. FadeChats has no calls or file transfer; it covers a short written exchange, with pictures, that leaves nothing behind when it ends.
Is there a Signal alternative that needs no phone number?
For a one-off conversation, yes. FadeChats needs no number, account or app on either side: you open a room and send the one-time link. The trade-off is scope: exactly two people, one conversation, no saved contacts.
