Unique key per room
Every room gets its own secret key, made in your browser and carried only in the invite link. Without the full link, the room is just scrambled data.

Create a secure room
Ready
One link
Share one link. That’s the invite.
Copy the link or show a QR code. Anyone with it can ask to join from any browser: nothing to install, no account, no number.
You control the door
You decide who gets in.
Someone opens your link and you see the name they picked. Approve or deny with one tap, lock the room once everyone is in, replace the link or remove anyone.
How it works
Four steps. Zero sign-up.
- 01Create
Name your room, set a limit and a self-destruct timer.
- 02Share
Send the private link. Revoke or replace it any time.
- 03Talk
Messages, photos, videos and documents, end-to-end encrypted.
- 04Vanish
End it, let it expire, or just leave. Access is gone everywhere.
Security by design
Built like a vault. Opens with a link.
Instant vanish
When a room ends, every open tab loses access at once. Old links and refreshes show nothing.
You control the door
Approve each person or set a password. Lock the room, replace the link and remove anyone instantly.
Anonymous by default
No account, no email, no phone number. Pick any name, or get a random one.
Clean file sharing
Photos are cleaned on your phone to remove hidden location data before they're sent. Risky file types are blocked.
Abuse protection
Rate limits, one-tap reporting and a 2FA-secured safety team keep rooms safe.
Made for moments
For the talks that don't need to stay.
Plan a surprise
Plan a birthday or a trip with friends, without a group that stays in everyone's phone.
Buy or sell online
Talk to a buyer or seller and agree on a deal, without handing over your phone number.
Share a document once
Send an ID, a form or a contract to your CA or lawyer. When the room ends, the file is gone.
A quick team huddle
Pull in a freelancer or a client for one discussion, without adding them to your work chats.
Temporary or saved?

Good to know
Temporary Rooms: your questions
Do I need an account to use DiffWeb?
No. There is no sign-up, no email and no phone number. Create a room, pick any display name or use a random one, and share the link.
How many people can join a room?
Each free room holds up to 5 people, including you. You can lock the room once everyone is in.
How long does a chat room last?
You choose when you create it: 15 minutes, 1 hour, 6 hours or 24 hours. You can also end the chat for everyone at any time.
What happens when the chat ends?
Everyone loses access immediately, on every device. The invite link stops working and the messages are no longer shown to anyone in the room.
Are my messages encrypted?
Yes, end-to-end. Your browser makes the room key and keeps it in the invite link, after the #, which is never sent to our server. Messages and files are locked on your device before they are sent, so not even DiffWeb can read them. Rooms are deleted automatically.
Can I share photos, videos and files?
Yes. You can send photos, videos and documents. Photos are rebuilt to remove hidden location data, and dangerous file types are blocked.
Can I make a custom chat room link?
Yes. Choose a link like diffweb.com/r/your-room. Without a password, you approve each person before they can join.
Is DiffWeb free?
Yes. Creating and joining private chat rooms is free.
Ready when you are
One link. One talk.
Then it's gone.
Name it, set the timer, share the link. That's all it takes.
