OpenSpartan is a project that I started as a labor of love and appreciation for the Halo universe. I’ve played every single Halo ever released since 2012 and one curious aspect was something that was always front and center for me - data around the gameplay. Since the release of Halo Infinite, I’ve been diving into the depths of the public, yet undocumented Halo Infinite APIs which allowed me to spin up quite a few projects in my quest to analyze my own match performance.

These projects include:

• A companion app for Halo Infinite that runs on Windows OpenSpartan Workshop.
• GruntAPI, an upcoming cross-platform Command-Line Interface (CLI) tool to query Halo Infinite data from the terminal.
• OpenSpartan Wait Times Datasets, an open-source aggregation of wait times for Halo Infinite.
• A CLI tool to get Xbox User IDs (XUIDs) from Xbox Gamertags.
• Bond Reader, an open-source tool that allows unpacking the contents of Bond-encoded API responses.
• Orion (formerly known as Grunt API), a full .NET implementation of the Halo Infinite API surface, that has since become closed-source, but still powers experiences such as OpenSpartan Workshop and GruntAPI.

The more I built those out, the more I discovered that I really enjoy building developer tools for Halo in my free time and documenting the end-to-end experience. OpenSpartan is all about shining a light on my explorations and enhancing the tools one might need to explore Halo Infinite statistics.
