Fast API Tester Chrome Extension

Lightweight API tester with history. Supports the basic HTTP methods GET, POST, PUT, DELETE, PATCH, as well as custom headers, query parameters, and JSON bodies. The extension remembers the last three requests.

Pro features are coming soon, and I’m also working on a custom paywall service (more details will be shared in upcoming posts).

Publishing delay

The extension requires the all_urls permission, which triggers a manual review by Google. This review can take weeks, and even minor permission issues may force a resubmission, extending the wait further. That’s why the extension isn’t live yet.

Call to action

  • Try the API tester if you need a lightweight tool for quick API calls.
  • If you notice a missing feature, let me know and I’ll consider adding it.
  • Interested in the custom paywall service? Updates are on the way.
