What it is
Boogie is a modeling language and tool for building program verifiers for other languages. It accepts Boogie language input, can optionally infer invariants, and generates verification conditions for an SMT solver. Z3 is the default solver; CVC5 and Yices2 support is experimental. The Civl extension lets users model concurrent and distributed systems. Boogie is self-hosted and distributed as a.NET global tool through NuGet. It requires.NET and a supported SMT solver, and the NuGet listing identifies version 3.5.7 as targeting.NET 8.0 or higher. The project uses the MIT License and is free at free. The repository names VCC and HAVOC for C, along with Dafny, Chalice, Spec#, and Move verifiers, as projects built on Boogie. Yices2 has a stated constraint: it works for unquantified fragments such as arrays, arithmetic, and bitvectors, but not for quantifiers, generalized arrays, or datatypes. Users can ask questions or report issues through the project issue tracker, and contributions are accepted through pull requests.

Strong points and limits
Strong points
- Free under the MIT License
- Can generate verification conditions for SMT solvers
- Z3 is the default solver
- Civl supports concurrent and distributed system models
Limits
- Requires .NET and a supported SMT solver
- CVC5 and Yices2 support is experimental
- Yices2 does not support several stated input features
Who it suits
Boogie suits developers and researchers building verifiers for other languages or checking contracts through Boogie input. It requires a .NET environment and a supported SMT solver.
Verdict
Boogie provides a self-hosted verification layer with contract-based deductive verification and an extension for concurrent and distributed models. Solver support varies, and the project lists .NET and an SMT solver as requirements.
