OnePASS

AUTONOMOUS SOFTWARE DEVELOPMENT PLATFORM FOR AI LEGACY SYSTEM MODERNIZATION AND TECHNICAL DEBT REDUCTION

OnePASS Autonomous Development Platform

OnePASS is Maven Technologies’ autonomous software development platform that helps enterprises modernize legacy estates and accelerate new application delivery with a clear focus on outcomes- reduce technical debt, improve security, and compress time-to-market. Built on a System 2 AI development architecture and agentic coding principles, OnePASS ingests entire repositories to create a domain-specific context graph so it can safely refactor monoliths, migrate monolith to microservices automatically, remediate vulnerabilities, and generate production-ready greenfield applications from validated requirements. Unlike short-context copilots or the latest vibe coding trends, OnePASS reasons across millions of lines of code, validates every change with extended inference-time testing, and delivers automated code refactoring for the enterprise without breaking critical behaviour. The platform is purpose-built for AI legacy system modernization and provides an automated, auditable pathway off end-of-life frameworks while preserving business logic and compliance constraints. For teams tackling technical debt, OnePASS offers measurable impact- faster feature delivery, lower operational cost, and a path to continuous modernization through repeatable microservices migration patterns and automated security vulnerability remediation. In greenfield scenarios, the engine turns ADAPT-approved designs into enterprise application development outputs that align to architecture, security, and performance guardrails—so you get production code with test-driven validation and documentation. Maven pairs OnePASS with our delivery framework and observability tools to create a closed loop from business intent to verified code at scale, delivering the strategic benefits of autonomous development while keeping engineering teams in control. Whether you’re evaluating automated code refactoring enterprise tools, exploring how to safely refactor a large legacy codebase, or investigating agentic AI coding assistants, OnePASS gives you an enterprise-grade, future-proof option for reducing technical debt and unlocking productivity with AI-first solutions. See how reimagining development and legacy modernization with OnePASS can transform your technology estate from a liability into a strategic advantage.

Efficiency through Technology

Autonomous Enterprise Development

System 2 AI with Full-Codebase Context

OnePASS is built on a System 2 AI development architecture and agentic coding principles that ingest entire repositories to build a domain-specific context graph, giving the platform a global understanding of call graphs, dependencies and business logic so it can reason deliberately across millions of lines of code; this full-codebase comprehension prevents breaking changes, enables autonomous code refactoring at enterprise scale, and pairs extended inference-time testing with test-driven validation to deliver production-grade changes that meet architecture, security and quality guardrails.

Safe

Designed for AI legacy system modernization, OnePASS provides an auditable, automated pathway off end-of-life frameworks by autonomously refactoring monoliths, remediating security vulnerabilities and migrating monoliths to microservices automatically; the platform preserves business behaviour and compliance constraints while systematically reducing technical debt, lowering operational cost and shrinking maintenance overhead, so organizations can modernize multi‑million‑line codebases without risky rewrites and realize repeatable microservices migration patterns with measurable enterprise impact.

Enterprise-Ready Greenfield Application Delivery

For new initiatives OnePASS translates ADAPT-validated requirements into production-ready applications by autonomously generating well-documented, tested code that aligns to enterprise guardrails for architecture, performance and security; this autonomous development capability compresses time-to-market, accelerates feature delivery and shifts engineering effort from maintenance to innovation, delivering enterprise application development outputs with built-in documentation, test-driven validation and deployment-ready code that fits into existing observability and delivery frameworks.

Measurable Risk Reduction and Continuous Modernization

OnePASS couples autonomous development with traceability and portfolio signals to create a closed loop from business intent to verified code, enabling automated security vulnerability remediation, continuous portfolio modernization and demonstrable technical debt reduction; enterprises benefit from faster, safer releases, lower total cost of ownership and stronger compliance posture while retaining engineering control, and the platform’s enterprise-grade validation and observability make it straightforward to quantify outcomes such as reduced development cost and accelerated time-to-market.

Become AI First

AI just scored a historic win in the International Collegiate Programming Contest, with OpenAI’s GPT-5 and Google’s DeepMind outperforming nearly every human team. The discussion focuses on whether this marks a real inflection point for AI, shifting from competition success to the frontier of scientific discovery. Key themes include public perception, the pace of progress, and what these results signal for the future of the field.
