Old stack in.
Watch a legacy system go into the machine, and a modernization plan come out.
Feed it your stack.
Two minutes, no access to your code. You get a pattern, your road through the method, and a pilot to start with.
Have the machine read your real code. Read-only.
How it will work: you ask us for a read-only assessment, and the plan is to run the same nine stations on the repositories you name. What you would get is an assessment report and a task board, like the boards our AutoPilot works from. This is a request, not a live connection: nothing connects to your code from this page.
- Read-onlyOnly the repositories you choose, with read access and no write access.
- Temporary by designThe plan is to read your code inside a temporary sandbox for this assessment only, and delete that copy when the run ends.
- Never used for trainingYour code is not used to train any AI model.
- You keep the resultsThe assessment and the task board are yours. Access is withdrawn when the assessment is done.
Inside the machine: nine stations, and you can stop after any of them.

MSApps is Certified in the Claude Partner Network.
Learn about the program at claude.com/partnersMSApps is Certified in the Claude Partner Network.
Our team holds Claude certifications. You work with people trained on how Claude is meant to be built with, not people learning on your system.
Led by a Claude Certified Architect
One accountable architect owns the design end to end: model and context strategy, agents and tools, evaluation and safety.
Anthropic's own method, run the way it was designed
We run the open-source code-modernization plugin Anthropic publishes, with every checkpoint, proof and sign-off it was built to include.
Built with Claude, in production
We build and run Claude systems in production for clients today, so the plan you get comes from delivery, not slides.
Questions
What is Claude-assisted code modernization?
It is upgrading, migrating or rebuilding legacy software with Claude doing the large-scale reading, mapping and drafting, under the plan and review of an engineering lead. Work is split into assess, map, extract-rules, brief, build, verify and harden phases.
What is the difference between uplift, transform and reimagine?
Uplift keeps the stack and moves versions. Transform moves to a different stack or platform while preserving behaviour. Reimagine rebuilds from extracted business rules when the existing code is not worth preserving.
Do you need access to our repositories?
For a measured assessment, yes, and we start with read-only access so nothing can be changed. Later phases deliver changes as pull requests that your own reviewers approve and merge.
How long will it take and what will it cost?
It depends on code size, number of repositories, test coverage and the pattern chosen, so we do not publish a headline price. We size the work in hours per phase, state the assumptions, and replace the first estimate with a measured assessment of your code.
Is MSApps part of the Claude Partner Network?
MSApps is Certified in the Claude Partner Network. Our modernization work is led by a Claude Certified Architect.
Can the code stay inside our own cloud?
Yes. Claude can be deployed inside your cloud perimeter (Amazon Bedrock, Google Cloud Vertex AI or Microsoft Foundry) so prompts and source code stay in your environment.
Have a system worth modernizing?
Tell us what it runs on. We'll suggest a pilot module.
