Edit HTTP Headers for Safari

About this app

Edit HTTP Headers for Safari is a Safari extension that lets you create rules to set or remove HTTP request headers for specific websites. Use it when you need Safari to send a custom header before a page, script, image, iframe, stylesheet, font, media file, or XHR/fetch request loads. Features: · Create Custom Header Rules: Add HTTP header rules for the websites you choose. · Set Request Headers: Replace or add a header value before Safari loads a matching request. · Remove Request Headers: Remove selected headers from matching requests when you do not want them sent. · Per-Website Rules: Create different header rules for different domains. · Resource Type Controls: Choose exactly where a rule applies, including main pages, iframes, scripts, images, stylesheets, fonts, media, and XHR/fetch requests. · iCloud Sync: Keep your header rules synced across iPhone, iPad, and Mac. · Privacy-first design: No data collection, tracking, or logging, your browsing stays completely private. · Multilingual support: Use the extension in multiple languages for a globally friendly experience. · Clean, user-friendly UI: Enjoy a streamlined design that integrates smoothly into your workflow. · Seamless Safari integration: Built to work across Safari on macOS, iOS, and iPadOS.
