Crashpad currently consists of a crash-reporting client and some related tools for macOS and Windows. The core client work for both platforms is substantially complete. Crashpad became the crash reporter client for Chromium on macOS as of March 2015, and on Windows as of November 2015.
Initial work on a Crashpad client for Android has begun. This is currently in the early implementation phase.
There are plans to bring Crashpad clients to other operating systems in the future, including a more generic non-Android Linux implementation. There are also plans to implement a crash report processor as part of Crashpad. No timeline for completing this work has been set yet.
