Magento (Adobe Commerce) Code Audit
A deep technical review to uncover hidden issues, performance problems, and set a solid foundation for future development
Magento stores often accumulate technical debt over time, from rushed deployments, third-party code, or multiple development teams. Our code audit identifies weaknesses, inefficiencies, and risks across your backend, frontend, and integrations, giving you a clear, prioritized roadmap for optimization and long-term scalability.
Why Magento Code Audit Is a Critical First Step
We often begin cooperation with a comprehensive code audit. In long-term Magento (Adobe Commerce) projects, it’s common to find multiple development teams involved over time, each with their own approaches, coding standards, and shortcuts. As a result, the codebase can become inconsistent, difficult to maintain, and prone to hidden issues that affect performance, security, and scalability.
A Magento code audit gives a clear understanding of the current technical state of your store. It reveals underlying problems that may not be immediately visible but could become serious blockers when scaling, upgrading, or optimizing your platform.
A code audit allows us to:
- Identify and prioritize technical debt
- Ensure code follows Magento best practices
- Uncover performance bottlenecks before they impact UX or SEO
- Detect outdated or vulnerable modules and integrations
- Build a development plan grounded in real, system-level insights
Rather than relying on assumptions or reacting to surface-level issues, we use the audit to shape a strategic, technically sound roadmap so that every future improvement is based on a stable foundation.
A great example is our long-term partnership with Eva.ua
We began by auditing their Magento store, uncovering performance and architecture challenges early on. That audit became the basis for a development strategy that now supports 27,000 orders and 500,000 visitors per day during peak sales events—while using just a fraction of the store’s available infrastructure capacity.

Magento Code Audit Scope
Our Magento code audit provides a full-spectrum review of your store’s technical health. We don’t just identify problems, we uncover hidden risks, technical debt, missed optimization opportunities and give recommendations on how to fix all those issues.
🔧 Code Quality
Poor code quality leads to hard-to-maintain systems, unexpected bugs, performance bottlenecks, upgrade failures, and higher future development costs. By ensuring your code is clean and modular, we reduce technical debt and make future enhancements faster, safer, and more predictable.
We review both backend and frontend custom code, focusing on Magento best practices, code readability, modularity, and maintainability. Custom modules (both in-house and third-party) are checked for structure, quality, and stability.
Common Issues We Identify:
- Business logic directly modified in Magento core files
- Heavy, unoptimized custom modules
- Non-standard override methods
- Poor commenting and documentation
- Uncaught exceptions, hidden runtime errors
🏗 Architecture & Tech Stack
A poorly designed architecture slows down development, increases downtime risk, and makes scaling expensive. The wrong tech stack decisions can lock you into underperforming infrastructure. We evaluate the overall system architecture, including module structure, data flow, and third-party system integration design. We review the underlying tech stack: PHP versions, database engines, caching systems, server configuration, and deployment strategy.
Common Issues:
- Use of deprecated or unsupported server technologies
- Inefficient server setup
- Missing staging, backup, or CI/CD deployment processes
⚡️ Frontend Performance
Slow-loading storefronts hurt user experience, SEO rankings, and conversion rates. Frontend issues are often underestimated but have a massive impact on revenue.
We perform detailed frontend analysis: page load times, Core Web Vitals (LCP, FID, CLS), JS/CSS bundling, asset optimization, lazy loading, caching headers, and image management.
Common Issues:
- Excessively large JavaScript bundles
- Render-blocking resources delaying first paint
- Non-optimized images slowing pages down
- Lack of proper caching for static resources
- Poor DOM structure leading to high CLS (layout shifts)
🔐 Security
Security gaps can lead to customer data breaches, PCI non-compliance, and reputational damage. Many vulnerabilities are introduced by extensions, misconfigurations, or unpatched software.
We check SSL configurations, HTTP security headers, access controls, admin exposure, credential management, etc.
Common Issues:
- Missing security headers (Content-Security-Policy, X-Frame-Options, etc.)
- Hardcoded admin URLs or credentials
- Publicly exposed debug or admin endpoints
- Unpatched security vulnerabilities in extensions or custom code
🔄 Integrations
Broken or inefficient integrations cause operational chaos: missing stock updates, failed orders, broken checkout flows, inaccurate reporting. We review ERP, CRM, PIM, and payment providers to check error handling, timeout management, data synchronization logic, and API performance.
Common Issues:
- Poor error handling causing silent data sync failures
- Inefficient polling or API abuse leading to system overload
- Fragile dependencies on external services without fallback mechanisms
- Latency issues that slow down checkout or inventory updates
📦 Third-Party Extensions
Poorly developed or outdated extensions are a source of security vulnerabilities, compatibility issues with other extensions, errors during upgrades, and unexpected bugs. We audit all installed third-party extensions for quality, conflicts, update readiness, and overall impact on site stability and performance.
Common Issues:
- Direct overrides of Magento core classes
- Deprecated code usage causing upgrade blockers
- Compatibility issues with other extensions
- Outdated modules that no longer receive security updates
Deliverables: What You’ll Receive
Clear insights. Actionable recommendations
At the end of the Magento code audit, you’ll receive a detailed and structured report (PDF) designed for both technical and business stakeholders. This is more than a list of problems—it’s a practical tool for planning, prioritizing, and improving your Magento store based on real evidence.
🔍 Magento Code Audit Report Includes:
- Issues Grouped by Technical Area. Organized by category: backend, frontend, performance, integrations, security, architecture, and more, so your team can easily navigate findings.
- Severity and Risk Level. Each issue is tagged as Critical, High, Medium, or Low, helping you understand which areas pose the most immediate risk to stability, performance, or security.
- Detailed Explanations. Each finding includes context and technical explanation—what the issue is, how it affects your store, and why it matters.
- Recommended Actions. Clear, actionable steps for fixing or improving each issue. These are written for developers but can be understood by technical managers and decision-makers as well.
- Optional Remediation Estimate. Upon request, we can include a time & cost estimate for our team to implement the recommended changes, allowing you to move straight from audit to improvement with no delay.
- Bonus Insights. We often include improvement opportunities beyond urgent fixes—for example, infrastructure suggestions, optimization best practices, or overlooked quick wins that could boost performance or reliability, as well as UI/UX improvement recommendations.
