StoreDog is a Docker‑compose‑based reference e‑commerce application (Next.js frontend, Rails/Spree backend, Redis, Postgres, ads, discounts, DB‑monitoring, Puppeteer, etc.) that intentionally contains performance bugs, security flaws, and other issues for users to detect and fix. It’s aimed at Datadog learners—developers, students, and engineers using Datadog’s Learning Center labs—to practice observability, APM, log, and error‑tracking techniques on a realistic, containerized app.
