Why we built these

Most DevOps configuration is YAML. YAML is great for machines and awful for humans — especially when reviewing a 600-line manifest you didn't write. So we built three small tools that turn the file in your clipboard into a picture you can reason about in seconds.

Every tool here runs entirely in your browser. There's no "paste your prod secrets into our textarea and hope" — there's no textarea on our server at all. Open DevTools and watch the Network tab; you'll see nothing leave when you paste.

And when a diagram isn't enough — when the question is really "but why does Kubernetes do it this way?" — that's what our explainer-video product is for.
