Alloy Analyzer vs Boogie
Both stand on formal verification tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APILinuxMac+1
Alloy Analyzer combines constraint-based model exploration with graphical views and counterexample generation. Temporal model checking adds a separate installation requirement, so users should account for NuSMV or nuXmv when planning that workflow.

Boogie provides a verification layer with contract support and a default Z3 solver. Adoption requires .NET and a supported SMT solver, while CVC5 and Yices2 support remains experimental.

Alloy Analyzer: what it does well
- Free, self-contained executable includes examples and source.
- Finds structures and counterexamples to properties.
- Graphical results can be customized.
- JAR can be used as an API.
What to know first
- Temporal model checking requires NuSMV or nuXmv.
- Those temporal tools must be available in PATH.
- Modeling uses the Alloy language.
Boogie: what it does well
- Generates verification conditions for SMT solvers.
- Z3 is the default solver.
- Civl supports concurrent and distributed system models.
- MIT-licensed and free.
- Accepts contributions through pull requests.
What to know first
