Lifecycle phase 10 of 13
Maintain and modernize: AI tools
Upgrades, migrations, legacy modernization and tech debt.
7 tools list this as the main phase, and 16 more tools cover it. Each claim is the vendor's own words, and every fact on a tool's page links to its source.
Main phase
AWS TransformAmazon Web Services“The first agentic AI service to accelerate transformation of Windows, mainframe, VMware and custom code, up to 5x faster (company claim).”
CodemodCodemod“Code intelligence and automation platform that gives agents compiler-aware context for framework upgrades, migrations and org-wide fixes.”
HypercubicHypercubic“Agentic AI for mainframe and COBOL modernization: turns COBOL into living documentation, captures tribal knowledge and transforms code.”
IBM Bob (formerly watsonx Code Assistant)IBM“IBM Bob, an AI coding agent that accelerates delivery and application modernization across complex enterprise codebases.”
Mechanical Orchard (Imogen)Mechanical Orchard“Imogen rewrites legacy mainframe systems into modern, cloud-ready code and verifies that outputs match, without breaking what runs today.”
ModerneModerne“A deterministic layer between your agents and your code: agents drive OpenRewrite recipes to make provably correct changes across whole business units.”
vFunctionvFunction“AI-driven modernization for large Java and .NET applications: gives AI coding tools the architectural context to refactor and rewrite.”
Also covers this phase
Tools whose main phase is another one.
Amazon Q DeveloperAmazon Web Services“AI coding assistant that writes, debugs and refactors code natively in your IDE and across AWS.”
Charlie (Daemons)Charlie Labs“Daemons: always-on AI processes, defined in Markdown, that work proactively across Slack, Linear and GitHub with no prompts.”
CosineCosine“The sovereign AI lab: trains models and specialised coding agents for organisations that need frontier capability inside secure environments.”
DevinCognition“Devin, the first autonomous software engineer, plans, writes, tests and ships production code inside your existing workflows.”
Diffblue Testing AgentDiffblue“AI testing agent that generates, verifies and fixes unit tests autonomously across enterprise Java codebases, legacy versions included.”
EllipsisEllipsis“Managed Claude Code agents in the cloud: define agents as config files in your repo and Ellipsis runs them to build features, fix bugs and investigate.”
Factory (Droids)Factory“Factory Droids automate coding, testing and deployment for startups and enterprises; also ships code review and a living AutoWiki per repository.”
G5G5 Labs“The semantic abstraction layer for AI-native development: natural-language intent becomes the source code.”Mistral VibeMistral AI“Agentic coding that understands your entire codebase: build, test and modernize autonomously from terminal or IDE.”
Ona (formerly Gitpod)Ona“Run a team of AI software engineers in the cloud, orchestrated, governed and secured at the kernel, inside your VPC.”
OpenHandsAll Hands AI“Open-source AI coding agent platform: start locally, automate engineering workflows, use any model and scale in the cloud or your VPC.”
PixeePixee“Automates vulnerability triage and remediation across your scanners: clears up to 95% of false positives and fixes the rest as merge-ready PRs.”Sentry (Seer)Sentry“Error monitoring and tracing for developers; the Seer AI debugging agent uses logs, commits, traces and stack traces to fix issues.”
SourcegraphSourcegraph“Code understanding, oversight and evolution: gives humans and agents complete context across the largest, most complex codebases.”
SwimmSwimm“Agentic modernization, delivered: static analysis and AI map legacy applications so modernization is accurate, complete and on time.”
TemboTembo“Run any coding agent in the cloud: give every change its own computer, follow agent work, review results and see what merges.”
