  description

  Requestman is a powerful DevTools extension for frontend engineers and QA teams who need faster, cleaner network debugging.
  
  No proxy setup. No app code changes.
  Open DevTools, create rules, and shape request behavior in seconds.
  
  With Requestman, you can:
  
  Redirect requests to another URL or local file
  Rewrite URL strings on the fly
  Add, update, or remove query parameters
  Modify request body (static or JavaScript)
  Modify response body (static or JavaScript)
  Edit request/response headers
  Override User-Agent (preset or custom)
  Cancel specific requests
  Simulate latency with request delay
  Built for real debugging workflows:
  
  Fine-grained matching (URL/HOST, contains, equals, regex, wildcard)
  Advanced filters (page domain, resource type, method, request headers)
  Rule groups, quick toggles, drag-to-reorder priorities
  Import/export rules as JSON for team sharing
  Hit visibility via popup and on-page toast
  If you debug APIs, test edge cases, or validate UI under imperfect network conditions, Requestman helps you move faster with less setup friction.
  
  
  Release Notes (v1.0.0)
  
  Added popup panel to show matched rules on the current page
  Added on-page hit toast toggle for quicker signal control
  Improved sidebar and rule-tree actions, status visibility, and quick toggles
  Refined rule config/test UX, including condition summaries and layout polish
  Better i18n locale detection and label consistency
  Multiple UI and stability fixes across forms, menus, and responsive layout

  Release Notes (v1.0.1)
  
  Improved popup UX: moved the master switch to the logo area and added clearer enabled/disabled status labeling.
  Better action entry points: replaced parts of the old toggle flow with a dropdown-based interaction, with new/updated animated icons for clearer feedback.
  Fixed state sync behavior: background logic now reacts correctly to stored master-switch changes to prevent toggle desync.
  Polished UI details: refined popup spacing and visual effects (including hit-toast backdrop styling).
