Development Containers or just “devcontainers” add a layer of security, simplify developer onboarding enables developing in parallel with isolated environments.

For me, Devcontainers are a great addition to an AI Engineer’s toolbox, even though I don’t use them day-to-day.

I have setup Devcontainers with Claude Code using VS Code and the devcontainers cli, adapted it to a Python FastAPI based project, and documented it in this article.
