Backends

Backends extend the functionality of the SDK for some common frameworks and libraries. Similar to plugins, they extend the functionality of the Sentry SDK.

The Native SDK can use different backends that are responsible for capturing crashes. The backend is configured at build-time, using the SENTRY_BACKEND CMake option, with support for the following options:

• crashpad: This uses the out-of-process crashpad handler. It is used as the default on Windows and macOS.
• breakpad: This uses the in-process breakpad handler. It is used as the default on Linux.
• inproc: A small in-process handler which is supported on all platforms, and is used as default on Android.
• none: This builds sentry-native without a backend, so it does not handle crashes at all. It is primarily used for tests.

Breakpad and inproc both run "in-process", so they run in the same process as the application they capture crashes for. This means these backends can't send a crash to Sentry immediately after it happens. Instead, the crash report is written to disk and sent the next time the application is run. Since Crashpad runs in a different process it doesn't have this limitation.
