Every network at once
Each connection is pinned to its own adapter, so Ethernet and Wi-Fi really carry the same file together. The faster one takes the larger share; if one drops, the others take over its part.
More streams only when they help
It starts with 8 connections, measures, and goes to 16 or 32 only if the speed really follows. When a server says no, it steps back and asks again a second later instead of hammering.
A crash is not a restart
Twice a second Confluo records which bytes are safely on disk. In testing the process was killed 11 times and the server taken away once during a 1 GB file: the result was still byte-exact.
It says what is slow
The network path, a server that caps each connection, a server refusing connections, the disk, or your own limit: the app names the one cause instead of leaving you to guess.
Click download, Confluo takes it
The companion extension hands downloads from Chrome, Edge or Firefox to Confluo. It talks to exactly one address: 127.0.0.1 on your own PC. If Confluo is not running, the browser downloads as usual.
Watch every thread
Each network is a thread running into one stream, with total speed, average, peak and a stacked 60-second chart per network. Hover to read any moment.

Or just click download in your browser and let the extension hand it over.
Confluo measures and merges
It finds the number of connections the server likes and spreads the file over every network you have.
The file lands, checked
When the server publishes a SHA-256, Confluo compares it before calling the download done.

Same PC, same local test server, against Plexo (an open-source multi-network downloader). Times are medians; lower is better. This compares software with software, not your internet speed.

No account, no tracking, no server in the middle. The browser extension talks only to 127.0.0.1, with a pairing code that never leaves your PC.
FAQ
Short questions, straight answers
Is it free?
Yes. No account, no ads, no paid tier. The source is under the MIT licence, on GitHub.
Do two networks make it twice as fast?
Only when they are two different internet lines, such as home fibre plus a phone's 4G. Ethernet and Wi-Fi on the same router are still one line; Confluo notices that and tells you.
Why does Windows warn me?
The installer is not code-signed yet, so SmartScreen may ask: More info, then Run anyway. The one-line install checks the installer's SHA-256 before running it.
Does it do torrents or streaming-site videos?
No. Confluo downloads files over HTTP and HTTPS and tries to do that one thing well.
Is there a macOS or Linux version?
Not as an app yet. The engine is written for all three systems, but only the Windows build has been tested in full so far.
How do I uninstall it?
Settings, Apps, Confluo, Uninstall. The program files and the Start Menu entry go; the files you downloaded stay.
INSTALL · WINDOWS 10/11
Your next big file is waiting
powershell -c "irm https://confluo.nhaajt.com/install.ps1 | iex"
One line in PowerShell. Downloads the installer from this site, checks its SHA-256 and installs it quietly, for your user only. Run it again to update. Read the script first
Or the installer. It isn't signed yet, so Windows asks before running it: More info, then Run anyway. Download .exe
