About TestFCM.in

Our mission

TestFCM.in is a free developer tool created to simplify Firebase Cloud Messaging (FCM) testing. Mobile and web teams need a fast way to verify push notifications during development — without deploying a backend or writing curl commands every time credentials change.

We focus exclusively on the FCM HTTP v1 API, which is Google's supported method for sending notifications. The deprecated Legacy server key API is not supported because it no longer works for most Firebase projects.

What TestFCM offers

• Browser-based FCM HTTP v1 send form with validation and clear error messages
• Server-side proxy to avoid CORS when calling Google's FCM endpoint
• Step-by-step setup guide integrated into the testing workflow
• Save and re-test notification requests locally or via Google sign-in sync
• Original documentation, FAQ, and troubleshooting guides on this site

Who it is for

TestFCM is built for Android developers, iOS engineers, Flutter and React Native teams, and web developers integrating Firebase Messaging. If you are onboarding a new project, debugging token issues, or demonstrating push to stakeholders, this site gives you immediate feedback on whether your FCM pipeline works.

Security & privacy

OAuth access tokens and device tokens you enter are used only to send the notification you request. Saved requests may be stored in your browser or Firebase account if you choose to sign in. We do not sell personal data. Read our Privacy Policy and Terms of Service for details on cookies, AdSense, and acceptable use.
