On August 15, 2025, we are excited to announce the launch of ghrelgrab, a specialized utility designed to automate and simplify the process of fetching and extracting assets from GitHub releases.

What is ghrelgrab?

Fetching the correct binary from a GitHub release often involves tedious manual searching or complex scripting to match the asset name with your current operating system and architecture. ghrelgrab solves this by providing a streamlined CLI tool that handles the heavy lifting for you.

Key capabilities include:

  • Dynamic Token Substitution: Use placeholders like {os} and {arch} in your asset patterns, and let ghrelgrab substitute them based on your system’s properties.
  • Smart Versioning: Effortlessly target specific release versions or automatically grab the latest non-pre-release version.
  • Automatic Extraction: No more manual unzipping. ghrelgrab automatically extracts .zip, .tar.gz, and .tgz archives upon download.
  • Private Asset Support: Securely fetch assets from private repositories using GitHub tokens.
  • Docker Integration: Designed to be used as a build stage in Dockerfiles, allowing you to fetch dependencies efficiently without bloating your final image.

Why it Matters

For developers and DevOps engineers, the “last mile” of dependency management—getting the right binary into the right environment—is often a point of friction. Whether you are building a CI/CD pipeline or a custom Docker image, manually mapping architecture strings to GitHub asset filenames is error-prone and repetitive.

ghrelgrab removes this friction by providing a consistent interface for asset retrieval. By abstracting the mapping and extraction process, it reduces boilerplate in your scripts and ensures that your environments are always equipped with the correct version of your tools.

Getting Started

You can find the source code and installation instructions in the ghrelgrab repository. Whether you are integrating it into your automation scripts or using it as a standalone tool, ghrelgrab is ready to help you grab your releases with precision.
