Independent source code review for websites, webshops, and apps

As a code review company, we review source code for WordPress, Magento, Umbraco, and custom PHP and .NET applications, and give you an objective assessment with no obligation to hire us for the fixes.

Before buying or investing: you're acquiring a business, software, or platform and need to know whether the codebase is an asset or a liability before committing money.

Before switching developers: the system works, but you want an independent view of its maintainability before a transition.

After inheriting legacy code: it works, nobody understands it, and you need to know what you're dealing with.

When performance degrades: the site or app has become slow, unstable, or hard to change, and you need confirmation and prioritized fixes.

Before scaling: you're planning growth and need to know whether the codebase can carry more traffic, transactions, and features.

We review only technologies we actively work with: WordPress, Magento, Umbraco, and custom PHP and .NET. Reviewing unfamiliar platforms produces questionable results, so we don't do it.

Structure and readability: organized code versus tangled logic that's expensive to modify.

Coding standards: organization, naming, documentation, formatting, and framework-specific conventions.

Maintainability: whether new developers could take the code over without archaeology: documentation quality, change logs, and clean separation of custom code from the core.

Performance: inefficient database queries, excessive API calls, and resource-heavy operations, especially where you've reported slowness.

Theme and plugin integrity: whether core CMS code, commercial themes, or plugins were modified in ways that break future updates.

Integrations: the code connecting payment processors, shipping APIs, CRM, and marketing platforms, its error handling and its security.

Security: common vulnerabilities such as exposed credentials, insecure data handling, missing input validation, and outdated dependencies. We are not a dedicated security firm; penetration testing is out of scope.

We don't read millions of lines one by one. The review targets the areas that affect your goals, performance, and risk, which is where the value is.

Our source code audit needs repository access (GitHub, GitLab, Bitbucket) or a complete code copy via secure transfer. Most reviews complete within 5 to 10 business days, and the review runs as a fixed-price task approved by you before work begins.

You receive a written report: issues categorized by severity, specific code examples and file references, fix recommendations with effort levels, and optimization suggestions. A follow-up meeting with your development team is available. The report is yours: take it to your current developer, use it to collect quotes, or have us implement the fixes.

Code review combines well with our technical audit, the SEO/AEO/GEO and speed audit, and the UI/UX review for a complete picture; see the Software Review page.
