Code Audit Services for When You Need the Honest Answer
A code audit is an independent engineer reading your codebase and telling you, in plain language, what state it is in: what is solid, what is fragile, what is dangerous, and what it will cost to fix. It is how founders, investors and managers get a straight answer about software they cannot read themselves.
We look at architecture, security, performance, tests, dependencies, deployment and documentation, and finish with a verdict and a prioritized list. Every finding comes with the evidence, so you do not have to take our word for it.
This is for you if
- ✓A developer or agency built your product and you cannot judge the quality yourself
- ✓You are deciding whether to keep building on a codebase or start again
- ✓You are investing in or buying a software company and need technical due diligence
- ✓Every new feature takes longer than the last and nobody can explain why
This is probably not for you if
- ✕You want a rubber stamp for a decision already made — the report says what the code says
We would rather tell you now than take the project and disappoint you.
Worth knowing: The most expensive outcome of a code audit is a rewrite that did not need to happen. Most struggling codebases have three or four structural problems causing most of the pain. Fixing those in place is usually far cheaper than starting over, and we only recommend a rebuild when the numbers clearly say so.
What you get
Architecture review
How the system fits together, where the boundaries are, and which parts will block growth.
Security review
Authentication, access control, secrets, dependencies with known vulnerabilities, and data exposure.
Performance
Slow queries, missing indexes, oversized bundles, and the requests that make pages wait.
Maintainability
Tests, duplication, consistency, documentation, and how long a new developer needs to become useful.
Delivery and operations
How code reaches production, backups, monitoring, and the parts only one person understands.
Verdict and roadmap
Keep, fix or rebuild, with effort estimates for the fixes, ordered by risk and value.
Technical due diligence for investors and buyers
Before buying or investing in a software business, a code audit answers the questions a pitch deck cannot: does the product work the way it is described, who really understands it, how much hidden work is waiting, and what would break if the founding developer left.
Due diligence reports are written for the deal team, with the risks that affect value separated from the ordinary technical debt every product carries.
What we need from you
- Read access to the code repository, and to the infrastructure if it is in scope.
- An hour with whoever knows the system best.
- Any existing documentation, however out of date.
- A sentence on the decision the audit is meant to inform.

Ask us first →How it works
Scope
Which decision the audit supports, which repositories and systems are in scope, and the deadline.
Fixed quote
One price, agreed before we read a line of code.
Review
The code read, run and measured, with a short call midway to check our understanding.
Report and walkthrough
A written report and a call to go through it, including the questions you did not think to ask.
Work you can check
Real work that uses the same skills. Every card links to something you can open and inspect yourself.
Questions
How much does a code audit cost?
Audits start at $1,500 for a small codebase and usually run $1,500–$6,000 depending on size and how many systems are involved. Technical due diligence for an acquisition tends to sit at the upper end because of the deadline and the report format.
How long does a code audit take?
Five to ten working days for most codebases, including the report. Urgent due diligence can move faster if access is ready on day one.
Which languages and frameworks do you audit?
JavaScript and TypeScript across React, Next.js and Node.js, PHP and WordPress, and the databases and hosting around them. For other stacks we will tell you honestly whether we are the right reviewers.
Will you fix the problems you find?
If you want us to. The audit stands on its own and is written so your own developers can act on it. If we do the fixes, the audit is not wasted, because the work is already scoped.
Do you sign an NDA?
Yes, before we see any code.
