Let’s talk

Claude Code audits focus on what happens after AI-assisted development produces a working codebase. Depending on the provider, that can include source-code security, authentication and authorization, architecture, dependencies, test quality, performance, infrastructure, and production readiness. The companies below work specifically with Claude Code, AI-generated software, or broader vibe-coded applications and offer different levels of review and remediation.

1. Gilzor

Gilzor works with products built using Claude Code, Cursor, Bolt, Lovable, Replit, v0, and similar AI development tools. Its audit-first option reviews the codebase and architecture, then assesses security, reliability, scalability, and other production-readiness gaps. Gilzor can also continue beyond the assessment into implementation when a product needs stabilization, security fixes, infrastructure work, testing, or preparation for launch. The approach is relevant to founders and product teams that already have a functioning AI-built application but need an engineering review before exposing it to more users, traffic, or operational risk.

Key Facts

  • Core services: Claude code audit, code review, architecture assessment, security review, reliability assessment, scalability review
  • Best for: AI-built products moving from a working prototype toward production
  • AI development tools: Claude Code, Cursor, Bolt, Lovable, Replit, v0
  • Audit options: Light audit and full audit
  • Location: Warsaw, Poland, with an additional office in Limassol, Cyprus

4. OSKI Solutions

OSKI Solutions is particularly relevant when a Claude Code repository is part of an existing system that needs modernization rather than an isolated code review. Its modernization process begins with a technical audit covering the codebase, data, integrations, and manual workflows. The team then establishes a modernization roadmap, adds tests and observability where required, and can handle integration or incremental re-architecture. That structure suits organizations that want the audit findings converted into engineering work instead of stopping after the assessment.

Key Facts

  • Best for: AI-assisted codebases connected to legacy or enterprise systems
  • Core services: Technical audit, legacy modernization, system integration, custom development
  • Audit focus: Codebase, data, integrations, workflows, modernization risks

5. Softblues

Softblues provides a Claude Code audit involving an AI-built operational application that contains about 58,000 lines of code. Its review covered security, application structure, automated testing, error handling, and go-live risks, followed by remediation planning and an AI development setup for the client's internal team. This practical Claude Code experience makes Softblues relevant to organizations that have already built a substantial application with AI and need to determine whether the foundation can safely support production use. The company can also move from assessment into security hardening, modularization, automated testing, deployment work, and team handover.

Key Facts

AddWeb Solution offers AI-generated code audit and remediation services for software produced with Claude Code, Cursor, Copilot, Replit, Lovable, Bolt, v0, and mixed human-AI workflows. Reviews cover security, architecture, test coverage, dependencies, deployment configuration, and technical debt. The company can also move directly into refactoring, quality gates, CI/CD hardening, observability, and production remediation after the assessment. AddWeb presents the audit as a structured engineering review rather than a scanner report, making it relevant to businesses that want both a diagnosis and an implementation team capable of addressing the findings.

Key Facts

9. Zegaware

Zegaware offers a Vibe Code Audit for AI-built software created with Claude and other coding tools. Senior engineers review security, performance, architecture, data handling, and compliance-related concerns, then provide severity-ranked findings and a production-readiness report. Remediation and re-auditing can be added when teams want the same provider to resolve the findings. Zegaware is particularly oriented toward founders, CTOs, and small or mid-sized businesses that want an accountable engineering sign-off rather than relying exclusively on AI self-review or automated scanning before putting an AI-built product into production.

Conclusion

Claude Code audits help businesses identify security, architecture, reliability, testing, and production-readiness issues that may not be obvious in AI-generated code. The companies in this list take different approaches, from focused security reviews to comprehensive technical audits covering infrastructure, scalability, compliance, and AI-agent workflows.

The right provider depends on the product’s stage and specific needs. Some companies focus on finding vulnerabilities, while others also offer remediation, refactoring, testing, and ongoing engineering support. For teams preparing an AI-built application for production, an independent Claude Code audit can provide a clearer picture of technical risks and the work required to build a secure, reliable, and maintainable product.
