Morph by Modelcode
AI for large-scale code modernization.
Morph modernizes large-scale production codebases through reviewable milestones, automated code review, and functional verification.
See the expected cost before Morph starts work on each milestone.
Language upgrades · Framework migrations · Architecture modernization
The systems that most need to change are the systems you can least afford to break.
Aging runtimes, security risk, and scarce expertise make change unavoidable. But critical software carries years of business logic, integrations, and operational behavior that must survive the migration.
One modernization. A sequence your team can control.
You decide. Morph plans, executes, and proves.
Align the team around one approved Project Spec.
Keep each milestone focused and reviewable.
Require evidence before anything merges.
The controls that keep every change moving.
Planning establishes what must be true. These controls make it visible, reviewable, and provable throughout execution.
Functional
Verification
Prove that real workflows behave the same before and after migration.

Code Review
Catch broken contracts, missed call sites, and architectural violations before approval.
Explore feature →Acceptance
Criteria
Define measurable requirements, then approve only when every criterion passes.
Explore feature →Team
Collaboration
Plan together, run milestones in parallel, and give every review issue an owner.

Modernization delivered where correctness matters.
From healthcare systems to safety-sensitive embedded software, Modelcode has delivered large migrations against real production constraints.
Modernized a production calculation platform while preserving calculation parity.
Read case study →Aerospace & DefenseAda 2012 → C++20Rebuilt safety-sensitive drivers with host-side protocol and state-machine validation.
Read case study →Enterprise SaaSAngularJS → React + TypeScriptDelivered the survey engine through stacked pull requests and feature-flagged validation.
Read case study →Global E-commercePHP + Go → KotlinConsolidated legacy services into a modern architecture running on Amazon EKS.
Read case study →Repository-scale modernization remains an open problem.
Across four agent configurations, average hidden-test pass rates fell from 91.3% below 10,000 lines of code to 15.3% beyond 50,000.
Performance declines as repository scale increases.
Coding agents accelerate implementation.Morph carries the modernization program.
What is the unit of work?
- Coding agent
- A bounded task
- Morph
- A modernization program
Who carries the program?
- Coding agent
- The developer
- Morph
- Project Spec and milestones
How is completion established?
- Coding agent
- Developer review

- Behavioral verification
Coding agents implement individual changes. Morph coordinates that work as a modernization program, keeping the plan, execution, and proof connected across every pull request.
See the Morph workflow →Run modernization workloads on your infrastructure.
ModelDaemon runs modernization on your infrastructure. It works against private systems and executes checkout, install, build, test, and application runs on your hosts. The host uses outbound-only connections to Modelcode and the services configured for your deployment.
Coordinates work and receives status and results.
Repository checkout, dependency installation, builds, tests, and application runs execute locally.
Work against internal repositories, registries, APIs, databases, and dependencies.
Every Modelcode connection is initiated by ModelDaemon - no firewall rule, VPN, tunnel, or reverse proxy.
SOC 2 Type 2 compliant
Independent controls and security documentation.
ISO/IEC 27001 certified
Certified information security management.
