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.
