HyperFetch

Fetch everything. Download faster.

A fast, multi-connection download manager for Windows. It splits each file across many connections, grabs streaming video and torrents, and pairs with a browser extension that sends your downloads straight to the app.

Website: https://tanumay-deb.github.io/HyperFetch/ · Download: latest release

Nothing to install: HyperFetch on the web takes a link, a magnet or a torrent from any browser, a phone's included.

Features

• Download large files much faster — splits each file across up to 16 connections at once (auto-detects support; falls back to a single stream otherwise).
• Never lose progress — pause and resume anytime, even across restarts; resume picks up from the bytes already on disk. Keep unfinished downloads in a folder of your choice; each moves to its own folder when it finishes. Organize downloads into named queues with their own limits; they start in the order of their number.
• Save streaming video — capture HLS (.m3u8) streams as one playable file (optionally rewritten as an ordinary MP4, so players can skip around in it), and download from YouTube, Vimeo, Twitch and more with a quality picker.
• Torrents & magnets — built in, no separate app needed. Pick which files to fetch, a whole folder at a time, and see how far each has got and how much of the torrent each peer has. A torrent that stalls is tried again by itself, the same torrent is never added twice (as a magnet, a .torrent file or a link), and the list sorts by seeds or peers.
• Grab downloads from your browser — right-click a link, click the badge on a video, or auto-capture downloads by file type. The extension for Chrome, Edge and Firefox hands them to the app.
• Updates itself — checks GitHub once a day, downloads the new version, checks it against the SHA-256 GitHub lists, and asks before installing.
• Track everything — every completed download is logged with lifetime totals and stats, and the status bar shows what this session has downloaded and uploaded.
• Privacy & control — speed limits, a global proxy, encrypted DNS lookups (DNS-over-HTTPS), a local relay that gets past a provider's site block, UPnP, optional SHA-256 checks, and keeping the PC awake while downloading.

Install

Windows (most people — no Python needed): download HyperFetch-<version>-setup.exe from the Releases page and run it. The installer bundles its own Python runtime, aria2c and ffmpeg, so it works on a clean machine, and from then on the app updates itself (Update to … in the sidebar; Settings → General). (Unsigned, so Windows SmartScreen shows "Windows protected your PC" on first run → More info → Run anyway.) Prefer no install? Grab the -portable.zip, extract it, and run HyperFetch.exe inside the folder.

Developers / other OS (needs Python 3.10+):

pipx install git+https://github.com/tanumay-deb/HyperFetch.git
hyperfetch

(No pipx? pip install git+https://github.com/tanumay-deb/HyperFetch.git, then run hyperfetch.)

The window opens and a local server starts at http://127.0.0.1:21456.

From source

pip install -r requirements.txt
python main.py          # or double-click HyperFetch.bat
python api_server.py    # headless: queue downloads with no window

Browser extension

1. Install it for your browser: Chrome Web Store (also Brave), Firefox Add-ons or Edge Add-ons.
2. Start the app. Chrome and Edge pair with it on their own; Firefox asks once in the app, showing a code to match. If neither happens, open Settings → Browser Integration, copy the pairing token, and paste it into the extension popup.
3. Keep the app running. Right-click a link → Download with HyperFetch, or turn on capture to route browser downloads automatically (pick which file types in Settings).

1. Open chrome://extensions (or edge://extensions) and enable Developer mode.
2. Load unpacked → select the chrome_ext/ folder.

Users site

There is a separate build, HyperFetch Server, that serves a multi-user site: accounts, per-user storage quotas, retention, an invite code and an audit trail. It is not part of this repository and not part of the desktop app — a download manager is not a hosting service, and keeping them apart is how you avoid publishing a machine you did not mean to.

The desktop app has a web client instead: one page, your own network, one password, off by default — see Web client.

Web client

Use the app from another browser or your phone (Settings → Web Client):

1. Turn on Enable web client and set a username and password.
2. On this PC, open http://127.0.0.1:21456/ui/. For your phone, also turn on Allow access from my network (it then needs a password of at least 8 characters) and open the same page at this PC's address.

It shares nothing with the browser extension: the extension pairs with a token, the web client signs in with its own password.

How it works

Part	Role
downloader.py	segmented HTTP downloader (ranges, retry/backoff, merge)
torrent.py / hls.py / yt_dl.py	torrent, HLS, and media-page engines
queue_manager.py	priority queue, concurrency, scheduler
history.py	completed-download log + stats
api_server.py	local Flask server the extension talks to
gui2/	the desktop GUI
web/	the web client's page
chrome_ext/ · edge_ext/ · firefox_ext/	the browser extension (kept in sync)

The GUI and the server share one queue, so browser-sent and manually-added downloads land in the same list. Everything runs on your machine — no accounts, no tracking. Settings and state live in %APPDATA%\HyperFetch\.

Tests

pip install -r requirements-dev.txt
pytest                                  # Python suite (offline; the real-engine tests need aria2c and ffmpeg)
cd chrome_ext/test && npm install && npm test   # extension tests

Build (Windows)

.\build.ps1             # -> dist\HyperFetch\ (portable app)
.\build.ps1 -Installer  # also builds the setup.exe (needs Inno Setup 6)

Code signing policy

Free code signing provided by SignPath.io, certificate by SignPath Foundation.

The application was made on 6 October 2026 and is waiting for an answer. Releases up to and including 2.8.5 are not signed; the first signed release will say so in its notes.

• What is signed: HyperFetch.exe and the installer, built by GitHub Actions from the tagged source in this repository (.github/workflows/release.yml). The bundled aria2c and ffmpeg are other projects' binaries and are not.
