A CLI batch downloader for your Bandcamp collection.
Bandsnatch is a Rust tool for downloading all of your Bandcamp purchases all at once in your desired format, and being able to be run multiple times when you buy new releases.
This project is heavily inspired by Ezwen's bandcamp-collection-downloader, which I used myself before this, specifically existing to help me learn Rust, but also to add some improvements over it that I've wanted.
This tool is still currently a work in progress, so bugs and other weirdness may occur. If anything weird happens or something breaks, please open an issue about it with information and reproduction steps if possible. Specifically testing use of this with large collections would be very helpful to see if there's any areas that I need to improve in.
If you're a developer poking around in the code, please note that this is my first proper project written using Rust, so code quality may be subpar, especially in terms of memory usage. If you have any ideas to improve the project in general I'd love to hear them.
The most basic usage is along the lines of
bandsnatch run -f <format> <username>
, as it will try to automatically fetch
cookies from a local cookies.json
. But if this
fails you can provide the -c
option with a path to a cookies file to use.
For more advanced usage, you can run bandsnatch run -h
to get output similar
to the following.
Run Bandsnatch to download your collection
Usage: bandsnatch run [OPTIONS] --format <AUDIO_FORMAT> <USER>
Arguments:
<USER> Name of the user to download releases from (must be logged in through cookies) [env: BS_USER=]
Options:
-f, --format <AUDIO_FORMAT> The audio format to download the files in [env: BS_FORMAT=] [possible values: flac, wav, aac-hi, mp3-320, aiff-lossless, vorbis, mp3-v0, alac]
-c, --cookies <COOKIES_FILE> [env: BS_COOKIES=]
--debug Enables some extra debug output in certain scenarios [env: BS_DEBUG=]
-d, --dry-run Return a list of all tracks to be downloaded, without actually downloading them
-F, --force Ignores any found cache file and instead does a from-scratch download run [env: BS_FORCE=]
-j, --jobs <JOBS> The amount of parallel jobs (threads) to use [env: BS_JOBS=] [default: 4]
-n, --limit <LIMIT> Maximum number of releases to download. Useful for testing [env: BS_LIMIT=]
-o, --output-folder <FOLDER> The folder to extract downloaded releases to [env: BS_OUTPUT_FOLDER=] [default: ./]
-h, --help Print help information
Besides these options, you can also use environment variables with the option
name in SCREAMING_SNAKE_CASE
, prefixed with BS_
, so that if set up correctly
you can just run bandsnatch run
and have it automatically download your
collection to the folder you want.
bandsnatch run -c ./cookies.json -f flac -o ./Music ovyerus
This would download my entire music collection into a local "Music" folder, and
also create a bandcamp-collection-downloader.cache
in the same directory,
which then gets read on future runs in order to skip items it has already
retrieved.
Because Bandsnatch does not manage logging into Bandcamp itself, you need to
provide it the authentication cookies. For Firefox users, you can extract a
cookies.json
with the
Cookie Quick Manager extension,
and on Chrome, you can use the
Get cookies.txt LOCALLY extension,
to extract the cookies in the Netscape format, which Bandsnatch also supports.
If you don't provide the --cookies
option, Bandsnatch will attempt to
automatically find a file named cookies.json
or cookies.txt
in the local
directory and load it.
Binary builds of Bandsnatch are available on our releases page for Windows, Mac (both ARM & Intel), and Linux (various architectures).
If you use Nix, Bandsnatch is available as a flake. You can
try it out without installing via nix run
or nix shell
:
nix run github:ovyerus/bandsnatch -- --help
nix shell github:ovyerus/bandsnatch
You can install it permanently with nix profile install
, or by adding it to
your NixOS/Home Manager configuration.
brew install ovyerus/tap/bandsnatch
scoop bucket add ovyerus https://github.com/Ovyerus/bucket
scoop install bandsnatch
Bandsnatch is also available on the AUR. Either use your favourite AUR helper, or you can install it manually via the following:
git clone https://aur.archlinux.org/bandsnatch.git
cd bandsnatch
makepkg -si
Bandsnatch is also available from the official NetBSD repositories, but is not maintaned by myself.
pkgin install bandsnatch
cargo install bandsnatch
Pull this repository and run cargo build --release
, and look for the
bandsnatch
binary in ./target/release/
.
