Header Hub: Zero-Backend & Git-Synced Header Manager Take full control of your HTTP headers with enterprise-grade privacy and seamless team collaboration. Why Choose Header Hub? In an era of increasing data breaches, your development tools shouldn't be a vulnerability. Header Hub is a powerful, privacy-first browser extension designed for developers and QA engineers. It allows you to modify HTTP headers and session cookies, or intercept and redirect network requests without compromising security. Key Features 🛡️ 100% Privacy (Zero-Backend): We have no central server. Your rules and sensitive data stay exclusively in your browser’s local storage. We never collect, track, or sell your data. 🔄 Enterprise Git Sync (Pro): Synchronize rules via your own infrastructure. Supports GitHub, GitLab, and Self-hosted Gitea. Your data stays within your realm. ✨ Dynamic Variables: Support for {{timestamp}}, {{uuid}}, and {{random}} to inject dynamic values into your headers or cookies automatically. ⚡ High Performance: Built on the latest declarativeNetRequest (DNR) API, ensuring ultra-fast rule matching with near-zero impact on browser speed. 📂 Advanced Grouping: Organize complex rule sets into manageable profiles and groups.

Use Cases Testing & Debugging: Bypass CORS, modify User-Agents, inject Auth tokens, manage cookies, or redirect API calls to local servers.
