Lychee

Desktop · Electron · Plexo forkA download accelerator for macOS, Windows and Linux. Lychee splits each download across parallel connections, and across every network you have, so one slow stream stops being the bottleneck.

Overview

Most downloads crawl along on a single connection. Lychee asks the server for the file in blocks of up to 8 MB and keeps many streams fetching them at once, so a big download finishes in a fraction of the time.

It goes past one network too. If your computer has Wi-Fi and a phone tethered over USB, Lychee uses both for the same file - no VPN, virtual adapter or admin rights needed. Torrents work the same way, with magnet links and .torrent files spread across your networks.

Why Lychee

  • 01Parallel connections every network starts with 8 streams and scales up to 32 as they fill
  • 02Every network at once faster links take more blocks, and a dropped one leaves the rest running
  • 03Pause and resume progress is saved as you go, and Lychee checks the file has not changed before resuming
  • 04No slow finish near the end, a free stream races a slow block and the first to finish wins
  • 05Survives restarts and sleep streams pick back up when the computer wakes or a network reconnects
  • 06Queue and limits speed caps, Slow mode, data allowances per network and an overnight schedule
