Highlights

What makes it useful day to day

Not a hosted platform — a desktop app you install once. These are the areas people open most often.

01

API Studio

Send REST requests, save collections, import cURL and Postman exports. Preview JSON responses, copy headers, keep history on disk.

  • Collections
  • cURL import
  • JSON preview
02

Kube Lens & DevShell

Browse pods across clusters, tail logs in the panel, inspect env vars, and open shells in DevShell — local, Kubernetes, or Docker — with real terminal sessions.

  • Multi-cluster
  • Pod logs
  • PTY shells
03

Data utilities

Format and minify JSON, diff two payloads, generate schemas, convert CSV and YAML, encode Base64 — Monaco editors throughout, built for quick copy-paste work.

  • JSON Diff
  • Schema gen
  • Monaco
