0trace is a browser-to-browser file transfer and chat tool built on WebRTC.
The main idea is simple: no upload step. Files go directly from sender to receiver, and the server only handles signaling.
It is designed for quick two-person sessions:
- direct P2P transfer
- chat in the same session
- no account or install
- large file streaming
I’d love feedback on the connection flow and whether the product feels meaningfully better than upload-first tools.
