Request Thru is a free Chrome extension designed to enhance network request management by allowing users to customize request headers effectively. The extension enables the addition of custom headers to network requests, which can be restricted to specific domains through the initiatorDomains feature. This provides users with flexibility when interacting with various web services and applications.

In addition to custom header management, Request Thru offers API-based header value settings, enabling users to dynamically process and apply header values by fetching data from APIs periodically. Furthermore, the extension includes a feature that automatically detects and blocks excessive network requests from websites or tabs, ensuring optimal browser performance. This comprehensive tool is ideal for users seeking to streamline their web interactions.
