ESBMC is an open source, permissively licensed, context-bounded model checker based on satisfiability modulo theories for the verification of single- and multi-threaded C/C++ programs. It does not require the user to annotate the programs with pre- or postconditions, but allows the user to state additional properties using assert-statements, that are then checked as well. Furthermore, ESBMC provides two approaches (lazy and schedule recording) to model check multi-threaded programs. It converts the verification conditions using different background theories and passes them directly to an SMT solver. In addition, ESBMC provides C++ and Python APIs to access to the internals of ESBMC, allowing inspection and extension at any stage of the verification process.

ESBMC is a joint project with the Federal University of Amazonas, University of Bristol, University of Manchester, University of Stellenbosch, and University of Southampton.
