Twig

Twig is a high-performance terminal UI for exploring JSON and YAML files interactively. It turns deeply nested data into a navigable tree, letting you search, jump, and inspect complex structures without piping commands together or scrolling endlessly. Twig is designed for understanding data, not editing it. It fills the gap between cat/less (no structure) and heavy IDEs (too slow/GUI-based), making it perfect for production logs, Kubernetes manifests, and large API responses.
