Description
Modify, add, or remove HTTP request/response headers per site, with rule groups and import/export. HeaderForge is a privacy-first browser extension for developers and power users who need to modify HTTP request and response headers on specific websites. Create flexible rules to set, append, or remove headers for matching requests. Rules can target URLs using wildcard filters or regular expressions and can be limited to specific resource types. Organize related rules into groups, enable or disable them independently, or use the master switch to pause all rules instantly. Key features: Modify request and response headers Set, append, or remove header values Match requests by URL filter or regular expression Limit rules by resource type Organize rules into independently switchable groups View the number of active rules directly on the extension badge Import and export configurations as JSON for backup or sharing Available in English and Simplified Chinese HeaderForge works entirely in your browser using Chrome’s built-in `declarativeNetRequest` engine. Your configuration is stored locally on your device and is never sent to the developer or any third party. The extension contains no analytics, tracking, accounts, or remote code. HeaderForge is designed for legitimate development, testing, and debugging workflows. Users remain responsible for the rules they create and the websites to which they apply them.
