The problem

None, honestly — this one exists because building is fun. Helldivers 2 runs a persistent galactic war fed by live community data, and that data deserved a better view than spreadsheets.

The build

A real-time war dashboard: a custom canvas map with a deterministic starfield and faction fog nebulae, Major Order tracking, and telemetry from the community API cached on a 60-second TTL.

The interesting part — AI battle plans: Claude, with structured tool use, reads the live war state and generates battle plans with ROI-scored target selection. Not a gimmick bolted on: the AI consumes the same typed, Zod-validated data the UI does.

Why it’s small: ~2.6k lines of code, full-stack, with CI/CD via GitHub Actions and App Insights observability. A v0.1 fan project, and labeled as one — no tests, no rate limiting yet. The charm is the build speed.

Fan-made, using the community API; not affiliated with Arrowhead Game Studios, and no game assets are bundled.

The method beat

Real-time data, beautifully visualized — and proof that the same system that ships client SaaS also ships joy in a weekend-sized codebase.
