Every byte, at full speed.

Splits every file across many connections and keeps each one busy until the last byte.

Simulated preview of the desktop app planned for v0.2. Measured results

01 / How it works

One file, many connections.

  1. One request learns the size and that the server sends ranges.

  2. Four connections start, each on its own part of the file.

  3. More join one at a time, only while the download gets faster.

  4. A connection that finishes early takes over half of the biggest part left.

  5. The last byte lands. The SHA-256 was computed on the way in.
