Description
Set and manage request headers per site or across all sites. RequestKit is a focused Chrome developer tool for setting and managing custom HTTP request headers. Create a separate header profile for each website, or use All sites mode to apply one shared set of headers across every HTTP and HTTPS site. Key features: - Detect the current tab's site automatically. - Switch between mutually exclusive Per site and All sites modes. - Add, edit, delete, enable, or disable header rules. - Use duplicate header names when needed; the last enabled matching rule takes precedence. - Apply changes immediately through Chrome's declarativeNetRequest API. - Preserve separate configurations when switching between modes. - Store all configuration locally on the user's device. RequestKit only affects network requests made after a rule is enabled. It does not change completed requests, inspect request bodies, or read response content. RequestKit has no account system, advertising, analytics, telemetry, remote code, or developer-operated server. It is designed for developers who need a clear and reliable way to test APIs, switch environments, enable debug flags, or apply custom request headers during development.
