Console monitoring

  • Captures console.log, info, warn, error and debug

State inspection

  • Live view of Redux, Zustand and any custom store in a dedicated State tab
  • Searchable, collapsible JSON tree of each store's current value
  • Timestamped snapshot history per store — scrub back through past values like a commit log

  • Ready-made attachReduxStore / attachZustandStore helpers
  • Safe serialization of functions, Maps/Sets, Dates and circular references
  • Throttled real-time updates as your state changes (view-only today; write-back on the roadmap)
