React Codebase Audit

Comprehensive analysis, architecture review, and actionable optimization recommendations for React applications.

Understand your React codebase before it becomes a bottleneck

A React Codebase Audit gives you a clear, technical picture of your frontend: what scales, what breaks under load, and what creates long-term maintenance risk. We analyze real production code — not just surface-level lint issues — and provide prioritized, engineering-focused recommendations. This service is ideal if your React app feels slow, fragile, or hard to extend — or before a major rewrite, migration, or scale-up.

What We Audit

Comprehensive analysis of your React codebase across multiple dimensions.

Architecture & Structure

  • Component hierarchy and separation of concerns
  • State management strategy and data flow
  • Reusability and coupling between modules
  • Folder structure and long-term maintainability

Performance & Core Web Vitals

  • Rendering behavior and unnecessary re-renders
  • Bundle size and dependency analysis
  • LCP, INP, CLS bottlenecks
  • Client-side vs server-side rendering decisions

Code Quality & Maintainability

  • TypeScript usage and type safety
  • Anti-patterns and technical debt
  • Consistency, naming, and abstraction levels
  • Test coverage and test strategy gaps

Scalability & Team Readiness

  • How well the codebase supports multiple developers
  • Risk areas for feature growth
  • Onboarding complexity for new engineers
  • Upgrade readiness (React, Next.js, dependencies)

Integration & Data Handling

  • API integration patterns
  • Error handling and loading states
  • Security and data exposure risks
  • Compatibility with backend and analytics systems

Deliverables

You receive a clear, structured audit report, not a generic checklist:

Executive summary (non-technical, decision-ready)
Detailed technical findings with examples
Performance and architecture risk assessment
Prioritized recommendations (what to fix first)
Short-term fixes vs long-term refactoring roadmap
Optional migration or redesign strategy

Typical Use Cases

React apps that slow down as features grow
Legacy React codebases with unclear structure
Startups preparing for scale or investor due diligence
Teams planning a migration to Next.js or SSR
Enterprises needing frontend stability and predictability

Step 02 — Code Review & Analysis

Deep dive into architecture, performance, and patterns.

Step 03 — Findings & Prioritization

Identify risks and quick wins.

Step 04 — Audit Report & Walkthrough

We explain results and answer technical questions.

Outcomes

Clear understanding of frontend health
Reduced technical debt and future risk
Actionable performance improvements
Better developer productivity
Confident decisions: refactor, migrate, or extend

Technologies Covered

React, TypeScript, Next.js, Vite/Webpack, REST & GraphQL APIs, state management libraries, testing frameworks, CI/CD.

Why This Audit Is Different

Real-world production experience
Architecture-first, not lint-first
Performance measured in user impact
Recommendations tailored to your business goals
No upselling — honest technical assessment

FAQ

How long does a React codebase audit take?

Audit timelines depend on codebase size and complexity. Typical audits take 1-3 weeks, including analysis, report writing, and walkthrough sessions.

Do you need access to our production code?

We typically need read-only access to your codebase (GitHub, GitLab, etc.) and optionally staging/production environments for performance testing. We can work with NDAs and security requirements.

What format is the audit report?

You receive a structured PDF report with executive summary, detailed technical findings, prioritized recommendations, and optional follow-up consultation sessions.

Can you audit Next.js applications?

Yes — we audit React applications including Next.js, SSR, RSC, and hybrid rendering setups. We assess both React patterns and Next.js-specific architecture.

Do you provide implementation after the audit?

The audit is a standalone service, but we can provide implementation services separately if you decide to act on the recommendations.

We provide React codebase audit services for startups and enterprises. Our Berlin-based team specializes in comprehensive React code analysis, architecture reviews, performance audits, Core Web Vitals assessment, and actionable optimization recommendations for React applications.
