HeaderX injects custom HTTP request headers into your Safari browsing session โ the essential companion for web developers, API testers, and QA engineers. Point HeaderX at your development environment, define your headers once, and flip them on whenever you need them. No proxy setup, no configuration files, no leaving the browser. DEFINE HEADERS AS JSON Describe your headers in a simple JSON editor โ paste an entire set at once: {"X-Debug-Mode": "enabled", "Authorization": "Bearer dev-token"} Or use the array format to keep headers saved but individually switched off. TWO VIEWS, ONE TOGGLE Edit as raw JSON or flip to List view, where every header gets its own checkbox. The master toggle in the corner turns everything on or off instantly โ your configuration stays saved either way. REUSABLE PROFILES Save named header sets โ one per project, environment, or test scenario โ and switch between them in two clicks. FEATURES โข One-tap master toggle โข JSON editor and checkbox list views โข Per-header enable/disable โข Named profiles for quick switching โข Settings persist across browser restarts โข Works in Private Browsing (optional) GOOD TO KNOW Standard header names (Authorization, Accept-Language, User-Agent, and other HTTP-spec headers) are applied to all requests through Safari's native rule engine. Custom header names (X-My-Header and similar) are applied to fetch and XHR requests made by web pages โ a Safari platform constraint on custom names in network rules. For typical API-debugging workflows, this covers exactly the requests you care about. Headers apply to every site while the toggle is on โ remember to switch off when you're done testing, especially with authentication headers. PRIVACY FIRST Everything stays on your device. HeaderX collects no data, phones home to no one, and contains no analytics. What you configure is nobody's business but yours.

Verdict
The clearest difference is in-app purchases: HeaderX at none against VoiceOver Designer's 1. HeaderX also leads on update cadence (every 8 days vs every 7 months). On price, ads, device support and iOS requirement there is nothing between them.
