Find out what is really inside your codebase.
Whether your software was written by an agency, a freelancer, an in-house team or largely by AI coding tools, a code audit gives you an honest outside view. We combine AI-assisted analysis that reads every file with senior engineers who judge what actually matters.
A code quality assessment that goes past the linter
Automated scanners produce long lists of warnings, most of which do not matter. A useful code audit separates the noise from the handful of issues that will hurt your business.
Security weaknesses
Injection risks, broken access control, exposed secrets and outdated dependencies with known vulnerabilities, checked in context rather than by pattern alone.
Structure and maintainability
How easy the code is to change safely: module boundaries, duplication, naming, and the files everyone is afraid to touch.
Testing that means something
Not just a coverage number. We check whether tests would catch a real regression in the flows that make you money.
Data handling
Schema design, migrations, validation and how personal data is stored, logged and deleted.
AI-generated code patterns
Plausible-looking code that nobody fully understands, copy-pasted variations of the same logic, and tests generated to pass rather than to verify.
Performance hotspots
Slow queries, chatty API calls and memory issues that show up as rising hosting bills or complaints from users.
Signs your code needs an independent review
Every small change breaks something else
A classic symptom of tight coupling and thin tests. An audit pinpoints where the fragility lives.
You are about to take over code from a departing vendor
Knowing the condition of what you are inheriting before the handover is complete puts you in a stronger position to get issues fixed.
Most of the code was written by AI tools
AI coding assistants produce working code quickly, but without experienced review they often skip authorisation checks, error handling and consistent structure.
Estimates keep growing for simple features
When developers pad every estimate, the codebase is usually telling them something the business has not heard.
An enterprise customer or regulator is asking questions
Security questionnaires and compliance reviews go much better when you already know your weak spots.
You simply cannot judge the work you are paying for
Non-technical owners deserve a clear, independent answer to "is this good?" at least once.
Code audit, penetration test or ongoing oversight?
These services are often confused. Each answers a different question, and picking the wrong one wastes budget.
| Code audit | Penetration test | Ongoing technical oversight | |
|---|---|---|---|
| Question answered | How healthy is this code? | Can an attacker break in? | Is delivery on track month to month? |
| Looks at | Source code, tests, dependencies | The running system from outside | Code, architecture, process, people |
| Duration | One-off, typically 1 to 3 weeks | One-off, days to weeks | Monthly, continuing |
| Output | Ranked fix list and roadmap | Vulnerability report | Regular reviews and guidance |
| Best when | You need a baseline or a second opinion | Security certification or launch | You rely on developers you cannot assess |
A code audit is not a substitute for a penetration test where one is contractually required. We will tell you if you need both.
How our code audit works
Context call
We learn what the software does, who built it, what worries you and which parts of the system carry the most business risk.
Automated sweep
Static analysis, dependency scanning and AI-assisted reading of the whole repository to map structure and flag candidates for closer inspection.
Senior manual review
Experienced engineers verify every flagged issue, walk the critical flows line by line, and discard false alarms so your team does not chase them.
Findings and walkthrough
A written report with issues ranked by impact and effort, example fixes, and a session with your developers to agree next steps.
An honest code review service, not a blame exercise
The best audits are useful to the developers as much as to the people paying them. We write findings that explain the risk and the fix, acknowledge what has been done well, and avoid the tone that turns a review into a defensive argument. Most codebases have a few serious issues and a lot of ordinary imperfection; we are clear about which is which.
AI has changed how we audit as well as what we find. Agentic tools let us read and cross-reference an entire codebase far more quickly than manual reading alone, which means more of the senior engineer's time goes on judgement: whether an unusual pattern is a bug, a deliberate trade-off or a security hole. AI suggestions are never passed on as findings until a person has confirmed them.
If the audit shows the problems are deeper than code quality, for example the architecture cannot support your growth or the project is badly off track, we will say so and point you to the right next step rather than stretching the audit.
Questions we often hear
What is a code audit?
A code audit is an independent, in-depth review of a software codebase to assess its security, maintainability, test quality and performance. Unlike routine peer review on individual changes, it looks at the system as a whole and produces a prioritised list of issues and recommendations.
How much does a code audit cost?
Cost depends mainly on the size of the codebase, the number of systems involved and how deep the security review needs to go. A focused audit of a single application is usually a short, fixed-scope engagement. After a discovery call we send a fixed proposal within 48 hours.
Can you audit code written with AI tools like Cursor or Copilot?
Yes, and it is increasingly the majority of what we see. AI-written code has recognisable failure modes, such as missing authorisation checks, inconsistent error handling and superficial tests. We look for those specifically and assess whether the team's review process is catching them.
Will a code audit disrupt my development team?
Very little. We need read-only repository access and a couple of short conversations with the developers. Most of the work happens without interrupting their day, and the final walkthrough is designed to help them rather than grade them.
What happens after the audit?
You can hand the report to your existing developers, ask us to help fix the most urgent issues, or set up ongoing technical oversight so problems do not build up again. There is no obligation to continue working with us.
