ModHeader vs VibeHeader
A practical comparison of request-header scope, project switching, sharing, and verifiable trust.
TL;DR: Choose VibeHeader for focused request-header work with public MIT-licensed source, local Profiles, precise Request Filters, and review-before-import sharing. It is not a replacement for response headers, redirects, mocks, or scripts.
⚠️ Update (July 2026): Chrome flagged ModHeader as malware and disabled it for many users. Here's what happened →
