What we make
Each extension has a free tier that stays useful on its own, and a single purchase that unlocks the rest. Install from the Chrome Web Store, or read the details on the product site first.
Header Forge
Modify HTTP request and response headers, redirects, and requests right in your browser, with rules you can toggle per site.
About
An independent studio
Mongoose Labs is an independent software studio building small, focused Chrome extensions. Each tool is self-contained: the work happens on your machine, the free tier stays functional, and paid features unlock with one purchase rather than a recurring bill. Questions, bug reports, and feature requests are welcome at support@mongooselabs.dev.
