modheader is described as 'ModHeader is a powerful browser extension that provides users with complete control over HTTP(S) headers. By allowing you to modify, add, or remove headers in a simple and user-friendly interface' and is an app in the development category. There are six alternatives to modheader for a variety of platforms, including Google Chrome, Microsoft Edge, Mozilla Firefox, Mac and Windows apps. The best modheader alternative is Requestly, which is both free and Open Source. Other great apps like modheader are OpenHeader, Header Override, Header Editor and Live HTTP Headers.
Requestly is a lightweight proxy available as a browser extension & desktop app to intercept & modify network requests. Using Requestly you can Modify Headers, Redirect Url, Mock API response, Delay/Throttle requests, etc.
Lightweight Chrome extension lets you add, modify, or remove HTTP request and response headers securely using declarativeNetRequest. Open source with no ads, tracking, or telemetry, minimal permissions, supports multiple profiles, per-URL filters, and import/export.
Header Override lets you modify or inject HTTP headers and cookies to customize web requests and responses.
Header Editor lets developers add, modify, or remove HTTP request headers per URL pattern using Chrome's MV3 declarativeNetRequest — no response-body access, rules stay local.
The goal of this project is to adds information about the HTTP headers in three ways:
Open-source Chrome extension to add & modify HTTP request headers and share configs in one click. A lightweight ModHeader alternative — no ads, no tracking.
