Crashlytics vs Crashpad

Crashlytics has no write-up on Specifiction yet; its figures are above.

Crashpad is an open-source crash-reporting system and client library for Android, iOS, Linux, macOS, and Windows. It embeds in an application, where a handler snapshots a registered process after a crash, saves a dump, and can send it to a collection server configured by the embedding client. Applications can also request process-state dumps on demand for diagnostics. Reports use the Windows minidump format with Crashpad extensions and generally contain loaded modules, thread registers and stack memory, selected operating-system state, and memory referenced by registers and stacks. Applications can add key/value annotations, application-specific metadata, and custom minidump streams. Uploads use HTTP or HTTPS through the Breakpad wire protocol, with a documented limit of one upload per hour and failed uploads aborted. The design requires applications to obtain and honor consent because process memory may contain sensitive data. Crashpad is a client-side component; a processor is planned without a completion timeline.
