While TLC is an explicit-state model checker, Apalache is a symbolic model checker. It checks safety for bounded executions and inductive invariants for unbounded executions, assuming that all data structures are finite. It also has an experimental implementation for liveness checking via liveness-to-safety reduction. The tool leverages the SMT solver
