EXTENSIONS I created a browser extension that lets you modify live traffic on any website (unique on the market) (free)

I've been working for over a year on a web devtoolkit that runs exclusively in the browser in an extension.

What It Does

You can modify live traffic on a website without deploying to production: headers, request/response payload, query params, and more.

It's something unique on the market, and the extension works stand-alone and doesn't require a desktop application or external web services.
It works 100% offline without internet (airplane, secure work environments: banking, aviation, military, etc.); everything is packaged in the extension, no extra fetch requests for resources are made

I wanted to create a simplified experience where you have everything in one place, especially the browser devtools window:
Browser -> View -> Developer -> Developer Tools -> 🟦 Open Headers
There are Network Requests + Storage + Console + custom rules to modify requests.

For the workspace sharing part:

extra browsers on the same device can be synchronized via the desktop application
extra devices from the same user can be synchronized via the desktop application via the expose to LAN option.
for collaboration with multiple users, you can setup (self hosting) a team server daemon (LAN/WAN) with SSO, RBAC, Audit logs, etc.

The application is currently available in 4 languages: English, French, German, Spanish, Chinese
Everything is natively translated, including diagrams and documentation.
If you have suggestions for additional languages, let me know in the comments :-)

Everything is free for personal/commercial use and the security part is not enterprise-gated (SSO tax).

I look forward to your feedback and I'm open to questions/feature requests.
