Fuselane

Free and open source

Every network. One fast download.

Fuselane downloads one file over your Wi-Fi, Ethernet and phone at the same time, then fuses the parts.

Sample speeds, as on a good home line. Turn a network off to see what it adds.

Measured on real machines

How one file rides every network

No VPN, no relay server, no admin rights. It all happens on your computer.

Split

Fuselane asks the server for the file in parts, the standard way a browser resumes a download.

Spread

Each part goes over whichever network is free. Faster networks simply carry more parts, so their speeds add up.

Fuse

Every part is checked before it joins the others. You get one file, exactly the one the server sent.

A server that doesn’t allow parts sends the whole file over one network.

One network, or both at once

The speeds come from a real network check on one Mac: Wi-Fi 117 Mbps, Ethernet 113 Mbps. Pick a file size and race them.

File size

Elapsed 11:24

  1. Wi-Fi alone 117 Mbps
    11 min 24 s
  2. Wi-Fi and Ethernet, with Fuselane 117 + 113 Mbps
    5 min 48 s

Both together: 5 min 48 s, which is 5 min 36 s sooner.

Times are worked out from those speeds. Real results depend on the server and on your lines: two cables to the same router share one line, so they won’t add up.

Built in, so you need fewer apps

Things that usually take a separate app or a subscription. Free, and on your computer only.

Get any file

  • Links, lists and patternsPaste one link or many. part[01-20].rar becomes 20 downloads.
  • TorrentsMagnets and .torrent files, with peers spread across your networks. Pick the files first.
  • Videos from pagesYouTube and 1,000+ sites, in the quality you pick, with your own copy of yt-dlp.
  • FeedsFollow a podcast or a project’s releases. New files download by themselves.
  • Whole pages, as a groupPick a downloads page’s files by type and get them as one group.
  • Mirrors and MetalinkEvery mirror at once, each checked to be the very same file.
  • A watch folderPut a .torrent, a Metalink or a list of links in a folder and it starts.
  • From your browserThe extension hands big downloads to Fuselane; the rest stay in the browser.
Fuselane following a podcast feed: new episodes download by themselves, a trailer is skipped by the words you chose, and a torrent waits to be opened.

Between your devices

  • Fuse Send linksA file of any size, straight from your computer, encrypted end to end.
  • NearbyComputers and phones on your network appear by themselves. Works with LocalSend.
  • Text between computersCopy on one, paste on the other. Phones can send text from their browser.
  • Folders kept in syncNew and changed files go to your other computer whenever both are on your network. No cloud.
  • Continue on another computerHand over a paused download, with everything downloaded so far.
  • Phones without the appScan a code to send or receive in the phone’s browser, on the same Wi-Fi.

Know your networks

  • Network checkSpeed, delay, jitter and how each network copes when busy, graded A+ to F.
  • A report for your providerOutages are noted as they happen, in a dated report you can send.
  • Data usedWhat each network carried this month, day by day.
  • Hours per networkUse the phone only on its night plan; downloads move over by themselves.
  • Limits and allowancesCap a network’s speed or its monthly data, and it’s never passed.
  • The phone for long downloadsShort downloads leave your phone’s data alone.

Stay in control

  • Do this nowOne download gets every network; the others wait their turn.
  • Ready byGive a download a time to be done. It goes first and says if it’s on track.
  • SchedulesDownload only between set hours, then sleep or shut down when it’s done.
  • Checked by itselfWhen a site publishes a SHA-256, Fuselane finds it and verifies the file.
  • Picks up where it stoppedA dropped network, sleep or a crash: it carries on without starting over.
  • Works with aria2 appsAriaNg and phone remote apps can add and watch downloads, once you turn it on.

Fuse Send

Send a file of any size. Nothing to upload.

Pick a file, copy the link, send it however you like. The other person’s Fuselane gets it straight from your computer, encrypted on the way and checked when it lands.

  • End-to-end encrypted: the key lives only in the link
  • No size limit: 4 GB or 400 GB, the same link
  • Same Wi-Fi: straight away. Across the internet: over IPv6, or when your router has UPnP on
  • Survives a restart: the same link keeps working
  • Keep Fuselane open until it arrives; it can wait in the tray

Good to know before you install

What Fuselane can’t do, or can’t do yet, in plain words.

All the limits, in the guide

  • Some servers send one stream

    A server that refuses parts sends the file over one network. It still downloads.

  • Different lines add up

    Two cables to the same router share one internet line, so they won’t be faster together. Wi-Fi plus your phone’s mobile data will.

  • Torrents look for peers on one network

    Peers are spread across your networks, but the DHT and tracker lookups go out over your default network.

  • A VPN that takes everything

    If a VPN routes all traffic through one connection, Fuselane sees one connection.

  • macOS asks once

    Fuselane isn’t notarized by Apple (that needs a paid account), so you choose Open Anyway once. The install script skips the step.

  • Windows may warn

    Until code signing through the SignPath Foundation is approved, SmartScreen may stop it. Choose More info, then Run anyway.

Free, and built in the open
