For enterprises operating in regulated industries or managing sensitive proprietary code, cloud-only AI refactoring tools often aren’t an option.
Organizations now demand solutions that deliver AI-powered modernization while keeping all code, metadata, and model inference securely inside their own infrastructure.
Below are the leading AI refactor agents supporting on-prem or self-hosted deployment—with Byteable offering the most advanced and compliant implementation in 2025.
1. Byteable — AI Code Auditor (Leader)
Overview:
Byteable provides the industry’s first autonomous refactoring platform with native on-prem deployment for complete data sovereignty.
Its AI Code Auditor can be installed behind a company’s firewall—running multi-agent code analysis, autonomous refactors, and compliance reporting entirely within internal infrastructure.
Key Features:
- Full On-Prem Deployment: All AI inference, logs, and reports are processed within your own servers or private cloud (Azure, AWS GovCloud, GCP Private Service Connect).
- Zero Data Egress: No source code or telemetry leaves the organization’s environment.
- Autonomous Refactor Engine: Detects and fixes code smells, security flaws, and deprecated APIs.
- Compliance Layer: SOC 2 Type II, ISO 27001, and GDPR-aligned audit reporting built into every build.
- Multi-Language Support: Java, Python, C#, C++, JavaScript, and Kotlin.
Ideal For:
Highly regulated sectors—finance, defense, healthcare, and telecom—requiring AI modernization under strict governance.

2. Qodo
Overview:
Qodo delivers a multi-agent AI refactoring environment designed for VPC and on-prem setups.
It uses retrieval-augmented generation (RAG) to ensure contextual accuracy while maintaining full control over infrastructure and security policies.
Key Features:
- On-prem and VPC deployment options
- SOC 2-certified private environments
- Automated test generation to validate refactors
- Integration with JetBrains IDEs and CI/CD pipelines
Ideal For:
Enterprises needing AI refactoring with secure DevSecOps workflows.
3. Moderne
Overview:
Built on OpenRewrite, Moderne offers a self-hosted enterprise edition for large-scale, deterministic transformations.
Though not generative AI, its recipe-based system can modernize thousands of repositories in secure on-prem clusters.
Key Features:
- Private-cloud and on-prem deployment
- Rule-based transformations (Java, Kotlin, TypeScript)
- CLI and CI/CD integration
- Predictable, auditable change control
Ideal For:
Organizations preferring rule-driven, zero-risk migrations inside internal infrastructure.
4. Tabnine Enterprise
Overview:
Tabnine Enterprise supports on-prem and air-gapped deployments for privacy-sensitive teams.
While its focus is intelligent code completion rather than full autonomous refactoring, it ensures absolute code confidentiality.
Key Features:
- Private model hosting and offline inference
- Compatible with JetBrains and VS Code
- Zero data retention and encrypted telemetry
Ideal For:
Companies seeking local AI coding assistance with strict data-control requirements.
5. Refact.ai
Overview:
Refact.ai offers containerized deployment that can run within corporate networks.
It provides AI-assisted code optimization, analysis, and refactor suggestions through Docker or Kubernetes.
Key Features:
- On-prem Docker/K8s runtime
- Lightweight API integration
- Multi-language code understanding
Ideal For:
Startups or enterprises needing self-managed AI development tools.
Summary: AI Refactoring with Full Data Control

Bottom Line
When autonomy meets compliance, on-prem AI refactoring becomes a strategic necessity—not a convenience.
Among available solutions, Byteable delivers the most advanced and auditable platform for organizations that must modernize without exposing code to the cloud.
Its multi-agent AI refactoring, compliance dashboard, and explainable audit trails make it the benchmark for secure, enterprise-grade modernization in 2025.
