Blazing fast TUI download manager built in Go for power users

Surge is designed for power users who prefer a keyboard-driven workflow. It features a beautiful Terminal User Interface (TUI), as well as a background Headless Server and a CLI tool for automation.
Most browsers open a single connection for a download. Surge opens multiple (up to 32), splits the file, and downloads chunks in parallel. But we take it a step further:
- Blazing Fast: Designed to maximize your bandwidth utilization and download files as quickly as possible.
- Multiple Mirrors: Download from multiple sources simultaneously. Surge distributes workers across all available mirrors and automatically handles failover.
- Sequential Download: Option to download files in strict order (Streaming Mode). Ideal for media files that you want to preview while downloading.
- Daemon Architecture: Surge runs a single background "engine." You can open 10 different terminal tabs and queue downloads; they all funnel into one efficient manager.
- Beautiful TUI: Built with Bubble Tea & Lipgloss, it looks good while it works.
For a deep dive into how we make downloads faster (like work stealing and slow worker handling), check out our Optimization Guide.
We are just two CS students building Surge in between classes and exams. We love working on this, but maintaining a project of this scale takes time and resources. That's where you come in!
If Surge saves you time, consider supporting the development! Donations go directly toward:
- Publishing the Extension: Paying the Chrome Web Store fee so you can finally install the extension officially (no more sideloading!).
- Dev Tools: Licenses for tools like GoReleaser Pro to help us automate our builds.
- Debrid Integration: Covering subscription costs so we can test and build native Debrid support.
Totally optional—your stars, issues, and contributions already mean the world to us! :)
Surge is available on multiple platforms. Choose the method that works best for you.
| Platform / Method | Command / Instructions | Notes |
|---|---|---|
| Prebuilt Binary | Download from Releases | Easiest method. Just download and run. |
| Arch Linux (AUR) | yay -S surge | Managed via AUR. |
| macOS / Linux (Homebrew) | brew install surge-downloader/tap/surge | Recommended for Mac/Linux users. |
| Windows | winget install surge-downloader.surgeor scoop install surge | Recommended for Windows users. |
| Dockerfile | See instructions | Run Surge in server mode with Docker Compose |
| Go Install | go install github.com/surge-downloader/surge@latest | Requires Go 1.25+ |
Surge has two main modes: TUI (Interactive) and Server (Headless).
For a full reference, see the Settings & Configuration Guide and the CLI Usage Guide.
Just run surge to enter the dashboard. This is where you can visualize progress, manage the queue, and see speed graphs.
# Start the TUI surge # Start TUI with downloads queued surge https://example.com/file1.zip https://example.com/file2.zip # Combine URLs and batch file surge https://example.com/file.zip --batch urls.txtGreat for servers, Raspberry Pis, or background processes.
# Start the server surge server # Start the server with a download surge server https://url.com/file.zip # Start with explicit API token surge server --token <token>surge and surge server bind the HTTP API to 0.0.0.0 (all interfaces) by default. This means the server is accessible via localhost (127.0.0.1) as well as your local network IP.
The API is token-protected. Generate/read your token by running:
surge tokenConnect to a running Surge daemon (local or remote).
# Connect to local server (auto-detected) surge connect # Connect to a remote daemon surge connect 192.168.1.10:1700 --token <token> # Equivalent global-flag form surge --host 192.168.1.10:1700 --token <token>By default, surge connect uses:
http://for loopback and private IP targetshttps://for public/hostname targets
These global flags are available on all commands:
--host <host:port>: target server for TUI and CLI operations.--token <token>: bearer token for authentication.
Environment variable fallbacks:
SURGE_HOSTSURGE_TOKEN
Download the compose file and start the container:
wget https://raw.githubusercontent.com/surge-downloader/surge/refs/heads/main/docker/compose.yml docker compose up -dGet the API token:
docker compose exec surge surge tokenSave this token - you'll need it to authenticate API requests and connect remotely.
Check downloads/API availability:
docker compose exec surge surge lsView logs:
docker compose logs -f surgeSurge ships a bundled Nerd Font for the TUI, but your terminal controls the actual font selection. See docs/FONTS.md for install steps and licensing details.
We tested Surge against standard tools. Because of our connection optimization logic, Surge significantly outperforms single-connection tools.

We would love to see you benchmark Surge on your system!
The Surge extension intercepts browser downloads and sends them straight to your terminal. It communicates with the Surge client on port 1700 by default.
