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 four alternatives to modheader for a variety of platforms, including Google Chrome, Linux, Mac, Mozilla Firefox and Windows apps. The best modheader alternative is Requestly, which is both free and Open Source. Other great apps like modheader are Header Editor, Live HTTP Headers and VibeHeader.
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.
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.
