The TLC checker is an explicit-state model checker for TLA+ specifications, built to verify system design correctness by exhaustively exploring all possible states—ensuring both safety and liveness properties hold.

Widely adopted for validating distributed systems, protocols, and concurrent algorithms, TLC is a powerful tool for guaranteeing reliability in complex software architectures.
