Breakpad vs Crashlytics

Breakpad is a free library and tool suite for capturing application crashes in compact minidump files and converting them into readable C and C++ stack traces. Its client can write a dump when a crash happens or when an application requests one. A symbol dumper converts compiler debugging information, including DWARF, STABS, and Windows PDB files, into Breakpad symbol files; a processor combines those symbols with dumps to produce traces. The sender can transmit dumps and application-defined key-value parameters to a crash server in a multipart HTTP POST request, with HTTPS supported. Developers provide the server and keep symbol files where the processor can access them. Documentation describes integration on Windows, macOS, and Linux, with Android also listed among the platforms. Windows out-of-process dump generation needs a separately run crash generation server. On Linux, crash callbacks should do little because application state may be unsafe; the client design also cautions against heap use and resource allocation after an exception. The project is hosted in the Chromium source repository and lists separate discussion and development mailing lists. The free plan costs nothing.
