Z3 is a high-performance SMT (Satisfiability Modulo Theories) theorem prover from Microsoft Research, written in C++. It solves logical constraints over booleans, integers, reals, arrays, and bit-vectors, with bindings for many languages including Python, C, C++, Java, .NET, OCaml, and WebAssembly.
Use cases
- solve SMT constraints over integers and bit-vectors
- verify program correctness with symbolic reasoning
- check satisfiability of logical formulas
- use an SMT solver from Python
- solve constraint puzzles programmatically
- integrate a theorem prover into a verification tool
- model and solve scheduling or planning constraints
When to choose
- you need a mature, actively maintained SMT solver with multi-language bindings
- you are doing formal verification, symbolic execution, or program analysis
- you need cross-platform binaries or WASM builds
When to avoid
- you need a lightweight dependency - Z3 is a large C++ library
- you only need simple boolean SAT solving where a smaller SAT solver suffices
- you need a pure high-level proof assistant like Coq or Lean
