tmp.tf – Cross-device text transfer with just a channel name, no signup

After sharing til.re) (a minimal countdown timer) here, I built another small tool: cross-device text transfer without accounts or apps.

Try now:

https://tmp.tf/helloworld

https://tmp.tf/sayhi

How it works:

1. 1Go to tmp.tf#yourchannel on one device

2. 2Paste your content

3. 3Open the same URL on another device — done

The channel name is the password. Use something like #a9$Kx2m for private transfers, or #meeting-notes for easy sharing.

Features:

• ●URL-as-state: the channel name lives in the URL, easy to share

• ●Auto-expires (no manual cleanup)

• ●Works in any browser

• ●Deployed on Cloudflare edge network

I also made a dark-themed version at copypa.st if you prefer that aesthetic.

Built this because I got tired of emailing myself links just to move a snippet from phone to laptop.

Would love your feedback!
