What are AI-Augmented Code Modernization Tools for GitLab?

AI-augmented code modernization tools use artificial intelligence to help organizations analyze, refactor, migrate, and modernize legacy software systems more efficiently. These tools combine generative AI, deterministic analysis, and automated transformation workflows to accelerate tasks such as code translation, dependency mapping, architecture analysis, documentation generation, and test creation. They often support modernization initiatives like moving monolithic applications to cloud-native architectures, converting outdated programming languages, and reducing technical debt while preserving business logic. Many platforms integrate with CI/CD pipelines, DevOps workflows, and observability systems to validate and monitor modernization efforts throughout the software lifecycle. By reducing manual effort, modernization risk, and migration timelines, AI-augmented code modernization tools help enterprises modernize legacy systems faster and at lower cost.

Diffblue Cover

Diffblue

Diffblue Cover analyzes your existing Java program and writes unit regression tests that reflect the current behavior of the code. The CLI tool works 100% autonomously, configuring itself from your Maven or Gradle environment. By bringing automation to the test-writing process, the CLI tool provides a speed boost for organizations that are working towards achieving DevOps goals like CI/CD. Since it fits into a CI pipeline, the CLI tool protects the whole codebase from regressions by shifting testing left. Diffblue Cover's unit regression tests run fast and verify new code changes immediately, helping users detect undesirable changes in the code’s behavior as early as possible, when they're the quickest, easiest, and cheapest to fix. And tests are automatically maintained, saving teams even more time.
