ktl is a Kubernetes CLI for building, previewing, and applying releases, but
the real glue is its SQLite-backed local state. Helm and the broader Kubernetes
workflow often feel fragmented, with too many separate tools for planning,
rollout tracking, logs, and status, and ktl is basically an attempt to make
that flow more cohesive. You still get fast feedback, rollout visibility, chart
planning, and sandboxed build workflows, but SQLite is what keeps it all
stitched together in practice. It holds run metadata, cached operational
context, and UI/CLI state in one lightweight embedded store, so you get
responsive behavior and useful history without adding more infrastructure.
