Create profiles to edit HTTP request headers in Chrome: set, append, remove, enable, and reorder custom headers. Header Leader is a local HTTP header editor for Chrome developers. Create reusable profiles to set, append, remove, enable, and reorder outgoing request headers for website, API, and staging-environment debugging. Create any number of profiles, enable several profiles at once, and organize each profile's header stack. For every header you can: - Set a value. - Append a value, including safe comma-separated emulation for custom header names that Chrome cannot append natively. - Remove the header. - Enable or disable it independently. - Reorder it with drag and drop. Use profiles to test custom headers, feature flags, API integrations, authentication flows, and staging environments. The extension applies profiles to top-level page loads and subresources, saves configuration locally, and reconciles Chrome's dynamic rules whenever settings change. A global switch can suspend all modifications and restore the previous active-profile selection later. Privacy by design: - No account. - No analytics or advertising. - No remote code. - No browsing-history collection. - No transfer of profile data to Presemantic or third parties. - Profile configuration is stored only in `chrome.storage.local`. Header Leader requires access to HTTP and HTTPS sites solely to apply the header changes the user configures.
