Observed signals from store listing text and review samples.

Listing positioning

Custom Headers positions itself as a privacy-focused, local-only alternative to popular header management tools like ModHeader or Requestly. It emphasizes compliance with Chrome's Manifest V3 architecture and highlights the use of the declarativeNetRequest API to ensure no traffic or user data is processed by the developer.

Inferred product pattern

Local-only utility extension using declarativeNetRequest for privacy and performance.

Review-backed pain points

Review-backed data is not available.

Observed feature gaps

As noted in the listing, the extension cannot inspect or rewrite request bodies, mock API response bodies, or throttle connections due to declarativeNetRequest API constraints.
