Frequently Asked Questions

What does Bosun do?

Bosun reduces risks, improves visibility, and accelerates execution of software modernization projects. Assess your legacy system, choose a migration path, and move one proven slice at a time while your team keeps shipping.

How is Bosun different from standard agentic coding tools?

On a public benchmark of 21 codebases rewritten in another language, 93% of tests still pass with Bosun. The same AI model without Bosun: 74%. Half of the differences our proofs caught would have slipped past the tests.

How much faster is a migration with Bosun?

8x faster legacy migration or more. 4x faster than standard agentic coding tools.

Which languages does Bosun work with?

4GL family, C, C++, C#/.NET, COBOL, Go, Java, JavaScript, TypeScript, Perl, PHP, Python, Rust. If it builds on Linux, we can port it.

How do you know the migrated code behaves the same?

One test, two implementations. The same input takes the same route through the legacy and the modern implementation, and the results are compared. Recorded differences show the exact deviation between the legacy and modern implementations.

Do we have to migrate everything at once?

No big bang. Slices are promoted one at a time. Traffic moves per route; what is not migrated keeps running on the existing system.

How do we start?

Start with a proof of value. One modernization solution with demonstrable value. Bosun engineers work with your engineers to connect Bosun safely to your environment and set up the migration process. You bring access to the codebase, impactful cases and reviewers. Bosun brings installation, workflow, guidance and measurement.

Is my code used for LLM training purposes?

No. We use privately provisioned Large Language Models. Your code never leaves your security perimeter and is never used to train any model.

How do you ensure my code is handled securely?

Security is a top priority. Code lives temporarily in hardened, isolated containers. Agents and workflows can only interact with their temporary git branch, never with the default branch.

Is Bosun secure and compliant?

We use enterprise-grade security practices and ensure compliance with major data privacy standards including GDPR. Enterprise customers can also deploy on-premise for full data sovereignty.

Can I integrate and tailor workflows to my needs?

Every use case is different. You can add MCP servers to agents, set up services like databases that run alongside your workflows, and fully customize trigger conditions and output behavior.
