Firebase Crashlytics is a lightweight, realtime crash reporter that helps you track, prioritize, and fix stability issues that erode your app quality. Crashlytics saves you troubleshooting time by intelligently grouping crashes and highlighting the circumstances that lead up to them. Get clear, actionable insight into app issues with this powerful crash reporting solution for Android and iOS. Find out if a particular crash is impacting a lot of users. Get alerts when an issue suddenly increases in severity. Figure out which lines of code are causing crashes.

Firebase Dynamic Links are links that work the way you want, on multiple platforms, and whether or not your game is already installed.

With Dynamic Links, your users get the best available experience for the platform they open your link on. If a user opens a Dynamic Link on iOS or Android, they can be taken directly to the linked content in your native game. If a user opens the same Dynamic Link in a desktop browser, they can be taken to the equivalent content on your website.

In addition, Dynamic Links work across game installs: if a user opens a Dynamic Link on iOS or Android and doesn't have your game installed, the user can be prompted to install it; then, after installation, your game starts and can access the link.


Firebase Invites are an out-of-the-box solution for game referrals and sharing via email or SMS.

Word of mouth is one of the most effective ways of getting users to install your game. In a recent study of thousands of smartphone users, researchers found that the #1 reason people discovered a game is because they heard about it from a friend or colleague. Firebase Invites makes it easy to turn your game’s users into your game’s strongest advocates.

When a user taps one of your game’s Share buttons and chooses the Firebase Invites channel - usually named "Email and SMS" - the Firebase Invites sharing screen opens. From the sharing screen, the user selects recipients from their Google contacts and contacts stored locally on the device, optionally customizes the invitation message and sends the invitations. Invitations are sent by email or SMS, depending on the available contact information, and contain a Dynamic Link to your app.

Instance Id

Firebase Instance ID provides a unique ID per instance of your apps. In addition to providing unique IDs for authentication, Instance ID can generate security tokens for use with other services.

Key capabilities:

  • Identify and track games
  • Generate Security Tokens
  • Verify app authenticity
  • Confirm game device is active
