About Headra
📋 Summary
Headra is a shared-source, cross-browser extension. Set, append, or remove HTTP request/response headers, as well as request/response body, and status. It implements a simple, and minimalist interface for ease-of-use.
✨ Features
- Set, append, or remove HTTP headers.
- Modify request/response body, and status (experimental).
- Supports regex patterns.
- Import/export profiles for sharing.
- Backup/restore profiles to/from storage.
- Securely limit modifications to specific site domains.
- Error reporting when a configuration is invalid.
- Presets included on install to get you started.
💡 Notes
- Headra will NEVER gather, and sell or share your data. All configurations are stored locally for operation purposes only.
- When adding intercepts, you will be alerted of "debugging". This is normal, and required for your security.
- When combining response intercepts with header overrides, provisional request headers may be shown. This is normal. Your headers will still be sent to the server.
