Comprehensive React Static Analysis Dashboard
ESL ReactStator gives QA and security teams a single dashboard for React codebases — component health, dependency risk, and prioritized refactor reports, run locally on Windows workstations, Linux, or WSL.
A Complete React Static Analysis Suite
Three integrated capabilities that map your component tree, score code and dependency health, and turn findings into actionable QA and security work.
Component Scan
Walk your React tree and produce a full inventory: components, hooks, context providers, render counts, and unused exports — across Create React App, Vite, Next.js, and Remix projects.
- JSX and TSX AST parsing
- Dead component and unused export detection
- Hook usage and dependency mapping
Dependency Health
Cross-reference your package.json with the React ecosystem to surface abandoned libraries, peer-dependency conflicts, vulnerable versions, and breaking-change risks before they reach production.
- React 16 to 19 upgrade paths
- Peer dependency conflict detection
- Optional deeper analysis with CodeQL
Refactor & QA Reports
Turn findings into prioritized work: class-to-function rewrites, prop-drilling fixes, memoization opportunities, and accessibility issues — all with file-level pointers your QA and engineering teams can ship.
- Class to function component plans
- Prop-drilling and context recommendations
- Markdown, HTML, JSON, and SARIF export
See ReactStator in Action
A real static analysis on an open-source React project — every component scored, every refactor and QA opportunity mapped.
Sample React App Audit
This example runs ReactStator against a representative React codebase to demonstrate the component graph, health score, dependency risk, and prioritized refactor backlog the dashboard produces.
You can explore the full interactive report here.
- 248 components inventoried
- 37 dead-code candidates identified
- 12 high-impact refactor opportunities
- Direct links to each source file
This sample uses a public open-source React project to illustrate ReactStator's static analysis and reporting output.

Inside the Dashboard
Source-level issues, prioritized findings, and a developer console — all in one local dashboard.
Why Choose ESL ReactStator?
Built for QA leads, security engineers, and platform teams who need clarity over a growing React codebase without sending source code to a third party.
Runs Locally
Full static analysis on your workstation or CI runner — no source upload, no telemetry, ready for air-gapped builds.
Windows-First, Cross-Platform
Built around Windows workstations, with Linux and WSL fully supported today and macOS planned.
Honest Refactor Plans
Prioritized, file-level recommendations — not a wall of lint warnings to ignore.
QA & Security Ready
SARIF and JSON outputs slot directly into existing QA dashboards and security review workflows.
Data Privacy
Your source never leaves your infrastructure — safe for proprietary and regulated codebases.
Framework Coverage
Works with React 16 through 19, plus Next.js, Remix, Vite, and Create React App.
Where Teams Use ReactStator
From legacy modernization to QA gating, ReactStator gives React teams the visibility they need to ship and review confidently.
Legacy React Modernization
Inherit a React 16 codebase full of class components and lifecycle methods? ReactStator builds a step-by-step migration plan to hooks, function components, and modern patterns.
- Class to function migration
- Lifecycle to hook mapping
- Incremental upgrade paths
Platform & Design Systems
Track adoption of your design-system components, find one-off duplicates, and measure component reuse across every app in the monorepo.
- Design-system adoption metrics
- Duplicate component detection
- Monorepo support
QA & CI Quality Gates
Wire ReactStator into pull requests to block regressions: rising prop-drilling depth, new dead components, or unsafe migration off deprecated APIs.
- GitHub Actions and GitLab CI
- SARIF output for QA dashboards
- Configurable thresholds
Regulated & Air-Gapped Teams
Run the same React static analysis inside secure environments — banking, healthcare, defense — without sending source code outside your network.
- Zero internet dependency
- On-premises deployment
- Audit-ready reports
