Quick answer
What is a code and architecture audit?
A code and architecture audit is an independent review of a software system’s code quality, architecture, security and technical debt. It covers the whole system, including a full security review, and ends with risks ranked by severity and a plan to fix them.
At MatrixTribe, senior engineers run the audit in 1 to 2 weeks, for a fixed price from $2,500 USD. You get a health report, a risk list and an estimate to finish or modernize the system.
Who it’s for
Is this right for you?
A project stalled, or a vendor left it half-built
An old system is slow, risky or hard to change
You need confidence before a security review or investment
You’re taking over code from another team
What we review
What’s included
- Code quality and maintainability
- Architecture and data model
- Security weaknesses and exposed secrets
- Outdated or vulnerable dependencies
- Test coverage and release process
- Performance and scalability risks
- Hosting, cloud and deployment setup
- AI-generated code, reviewed under GRACE
Not included: business process or AI use-case analysis, and mapping systems beyond this codebase. See the AI Readiness Assessment or the Systems and Data Review. Compare all four assessments →
Built with AI coding tools?
Auditing vibe-coded apps
Apps built mostly with AI coding tools (often called vibe coding) work in a demo but tend to share the same hidden problems. We check for them through GRACE, our AI code governance framework.
Grasp
Code no one on the team fully understands or owns.
Review
Security, design and maintainability never checked by an engineer.
Access
Secrets and data exposed in code, prompts or tools.
Consistency
Architectural drift: the same thing done several different ways.
Explainability
No record of why changes were made, or by which prompt.
What you get

FAQ
Frequently asked questions
How much does a code audit cost?
At MatrixTribe, a code and architecture audit starts at $2,500 USD for one application and typically goes up to about $12,000 USD for several services with deeper security and performance review. The price is fixed before work starts and credited toward a project signed within 60 days.
How long does a code audit take?
About one week for a single application and about two weeks for larger systems. You get a written report and a readout call at the end.
What access do you need?
Read-only access to your code repository and, if available, your hosting setup and documentation. We sign an NDA first, and all work runs under our SOC 2 Type II certified security controls.
Can you audit AI-generated code?
Yes, including apps built mostly with AI coding tools (vibe coding). We check for security holes, exposed secrets and architectural drift through GRACE, our AI code governance framework. For a faster, security-only check, see our Vibe Coding Security Audit.
What happens after the audit?
You decide. Use the report with your own team, or ask us to fix, finish or modernize the system. If you go ahead within 60 days, the audit fee is credited in full.
Do you need to fix the code yourselves?
No. The audit stands on its own. Many clients do continue with us, as Volterra and Cadents did, but there is no obligation.
