A doorbell-camera Halloween costume tracker goes open-source

The creator says they built the tracker in 2025 to see which Halloween costumes were most popular in their neighborhood. On October 30, 2026, they announced they had open-sourced it for others to try. They say it can run locally on supported hardware or be set up through Stripe Projects using Supabase, OpenRouter and Vercel, and shared a GitHub link in a reply.
