🚀 Open Headers: Advanced HTTP Header Management for Developers
Open Headers gives you complete control over HTTP request headers in your browser. This powerful extension lets you modify, add, and manage headers for specific domains with static values or dynamic content from various sources.
🤔 Why Open Headers?
As developers and API testers, we know the frustration of constantly modifying headers for different environments. Open Headers simplifies this with a clean interface and powerful automation features that make your workflow smoother.
✨ Key Features:
🔄 Dynamic Header Sources - Pull values from HTTP requests, environment variables, local files, and more
⚡️ Real-time Updates - Header values update automatically when source content changes
🌐 Multiple Domain Control - Apply different headers to specific domains using flexible URL patterns
🧩 Smart Formatting - Add prefixes and suffixes to dynamic values (perfect for auth tokens)
💾 Import/Export System - Share configurations with teammates or backup your settings
🔌 Companion App Integration - Access local system resources through our secure desktop app
✅ Header Validation - Automatic sanitization and validation of header values
🔒 Persistent Settings - Your configurations save automatically between sessions
👥 Perfect For:
👨💻 API developers testing with different authentication tokens
🔍 QA engineers switching between development environments
🛡️ Security professionals testing header-based vulnerabilities
🌐 Web developers troubleshooting cross-origin resource issues
🔧 Anyone who needs to customize HTTP headers for specific websites
⚙️ How It Works:
Open Headers runs in your browser, monitoring requests to specified domains and dynamically modifying headers before they're sent. For advanced features like local file access, the optional companion app securely provides these values to the extension.
📖 Open Source & Transparent:
We believe in open source software. Both the extension and companion app are fully open source, with code available on GitHub for review, contributions, and customization.
