packrat

🐀 Hauls every part of your big downloads — concurrent, resumable, single Go binary.

packrat is a cross-platform downloader for multi-part file hosting, made for grabbing FitGirl repacks from the terminal: it reads a text file of the repack's landing-page links, resolves each one to its direct download link, and fetches every part concurrently into one directory per archive.

Features

• Plain text input: one link per line, markdown bullets welcome, broken lines skipped with a note instead of failing the run.
• One output directory per archive, parts kept together and ordered.
• Live progress view with per-part bars, speed and a pause/resume key.
• Script-friendly --plain output that honors NO_COLOR.
• Byte-exact resume: interrupted runs keep .part files, rerunning the same command continues where it stopped.
• Graceful stop that preserves partial parts, plus explicit exit codes for scripting.
• Automatic retries with backoff; host-imposed Retry-After pauses are honored instead of hammered.
• Polite link resolution: paced and jittered requests, live cooldown display, and sustained rate limiting ends the run early with a clear rerun-later message.
• Resolves without a real browser: pages are fetched with a TLS fingerprint that impersonates one.
• --dry-run to preview the download plan before touching the network.
• Native binaries for Linux, macOS and Windows.

Quick start

Download the latest version

Copy your repack's part links into a text file (one per line), then run:

./packrat links.txt

Supported providers

Provider	Website
FuckingFast	https://fuckingfast.co
FileKeeper	https://filekeeper.net

Note

Requests toward the provider are paced and jittered, and rate-limit answers are waited out exactly as the host asks for. Politeness is what keeps long runs working.

Tip

The engine/host seams make adding a provider a small, isolated job. Pull requests are welcome.

Installation

Windows

1. Download the Windows archive from the latest release.
2. Extract it to a directory of your choice.
3. Open PowerShell or CMD in that directory and run packrat.exe on a links file.

Linux / macOS

Download the archive matching your platform, extract it and make the binary executable:

tar -xzf packrat-macos-arm64.tar.gz
chmod +x packrat

Optionally move it somewhere available in your PATH:

sudo mv packrat /usr/local/bin/

Build from source

Clone the repository and build the binary:

git clone https://github.com/EliasLd/packrat.git
cd packrat
go build -o packrat ./cmd/packrat

Usage

Basic syntax

packrat [options] links.txt

Options must come before the links file.

Options

Option	Description
-o dir	Output root directory. Default: downloads.
-c int	Parallel downloads. Default: 8.
-rc int	Parallel link resolutions. Default: 3.
-retries int	Attempts per part. Default: 5.
--plain	Never style the output — for pipes, CI and logs.
--dry-run	Print the planned download layout, resolve and download nothing.
--version	Print the build version and exit.

The links file

# one link per line; '- ' bullets and [text](url) markdown links work too
https://fuckingfast.co/AbC123#MyGame.repack.part01.rar
- https://fuckingfast.co/DeF456#MyGame.repack.part02.rar

The URL fragment names the download: a <name>.part01.rar style fragment downloads into downloads/<name>/ and keeps every part in order:

downloads/
└── MyGame.repack/
    ├── MyGame.repack.part01.rar
    ├── MyGame.repack.part02.rar
    └── MyGame.repack.part03.rar

Without a fragment, the part lands in unknown/ and keeps the file name the host page provides.

Pause, stop, resume

While downloading on a terminal:

• p pauses and unpauses the whole run.
• q or ctrl-c stops gracefully; unfinished parts stay as safe .part files.
• Rerun the exact same command afterwards to resume.

When the host asks for patience, the view says so instead of pretending:

[rate limit] cooling 30s: host rate limit (status 429): retry after 30s

Exit codes

0      ok
1      some part(s) failed
2      bad usage
130    interrupted

Examples

Choose another output root

packrat -o /mnt/archive links.txt

Gentler run

packrat -c 2 -retries 8 links.txt

Preview first

packrat --dry-run links.txt

Keep a plain log

packrat --plain links.txt | tee run.log

Contributing

Contributions are very welcome: new providers (the host seams are built for it), fixes for existing ones, UI or engine improvements, tests and documentation.

Development needs Go 1.27 or newer. make test runs the suite with the race detector, make lint runs golangci-lint. Feature work happens on feature branches with conventional commits.
