Overview

Product summary

Review the store description, core capabilities, and common use cases.

It enables you to

- Debug a remote web site, for which source map is usually disabled, with your local web server

- Test your local changes with actual data from remote servers - integration test before pull request

The idea and its implementation are based on HTTP and HTML web standards, independent to the framework of your choice, with the following constraints:

- It requires local server to respond with HTTP header, `Access-Control-Allow-Origin: *`. `*` can be replaced with the origin of your remote server.

- It doesn't work with `document.write()`.
