| Spec score · Formal Verification Tools | 8.1 (#7) | 7.5 (#22) |
| Concurrency | The Civl extension enables Boogie to model concurrent and distributed systems. | The site says K's rules make read and write access explicit, which supports defining concurrent languages with shared state. |
| Installation | Releases are packaged as a .NET global tool and can be installed with dotnet tool install --global boogie. | The official site directs users to install K from GitHub releases and provides a `kup` installation command. |
| Purpose | Boogie is an intermediate modeling and verification language used as a layer for building program verifiers for other languages. | K is a rewrite-based executable semantic framework for defining programming languages, type systems, and formal analysis tools. |
| Support | The project directs users to its GitHub issue tracker to ask questions and report issues. | The official site lists Discord as its most direct support channel and also links to a Matrix room. |

In their own words
Boogie
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.
