HashDrop is a privacy-first platform for transferring files and communicating in real time. Built on WebRTC and Next.js, it routes data directly between your devices with end-to-end encryption — nothing is stored on any server, and no account is ever required.

Quickstart

Send your first file or join a conference in under two minutes

File Transfer

Transfer files up to 10GB directly between devices

Video Conferencing

Host or join encrypted video calls with up to 50 participants

What is HashDrop?

HashDrop combines three core capabilities into a single, unified experience:
  • Peer-to-peer file transfer — Drop files up to 10GB directly to another device using a short Warp Code. Files never touch a server. SHA-256 verification confirms every byte arrived intact.
  • Video conferencing — Start or join a room via a code or QR scan. Powered by LiveKit, rooms scale to 50 participants with low-latency WebRTC video and audio.
  • Chat rooms — Create a disposable, ephemeral chat room to share text, links, or code snippets instantly. Rooms vanish when everyone leaves.
All three modes are accessible from both the web app and the native iOS/Android mobile app.

​
How it stays private

HashDrop uses a “zero trust” model:
  • No account or email is required — ever
  • No files or messages are stored on HashDrop servers
  • WebRTC connections use DTLS/SRTP encryption by default
  • Warp Codes expire in 5 minutes and are single-use
  • The signaling server logs nothing
