Simple, fast, versioned large-file storage for git.

gat is what git-lfs would be if it didn't need a special server, and what dvc would be if it did one thing. Point it at S3, Azure Blob, GCS, and other object stores (or a plain directory), gat add your large files or directories, and keep using git exactly as before — commit, push, pull, clone all just work. No clean/smudge filter magic: gat sync automatically reconciles the working tree with the current gat.lock.

Linux / macOS

curl -fsSL https://getgat.dev/install.sh | sh

Windows (PowerShell)

& ([scriptblock]::Create((irm https://getgat.dev/install.ps1)))

This downloads the latest matching release archive, verifies its checksum, and installs gat to your user-local bin directory. See Installation for version-pinned installs, manual downloads, and Cargo-based source installs.

Alternatively, install from source with Cargo:

cargo install --locked --bin gat --git https://github.com/getgat-dev/gat gat

Building gat from source requires Rust 1.91 or newer (the minimum supported Rust version, or MSRV, tracked by rust-version in Cargo.toml). Bumping the MSRV is considered a breaking change.

Run inside an existing Git repository, using a file Git does not already track. Replace the bucket and region and configure storage credentials.

gat init
gat remote add origin 's3://my-bucket/assets?region=eu-west-1'
gat add models/encoder.safetensors
git add gat.lock gat.yaml
git commit -m "Track encoder weights with gat"
gat push --remote origin

Adding a remote does not select a default. Use --remote origin for each transfer, or run gat remote default origin. See remote setup for sharing storage configuration and How Gat works for the lock, cache, and working files.
