Built a chrome extension with Claude Code?
We'll make it production-ready.
Chrome extensions have unique security considerations — they run in users' browsers with elevated permissions, can access browsing data, and must pass Chrome Web Store review. AI tools can scaffold an extension quickly, but the security requirements, Manifest V3 compliance, and store submission guidelines need careful attention.
Chrome Extension challenges in Claude Code apps
Building a chrome extension with Claude Code is a great start — but these challenges need attention before launch.
Manifest V3 compliance
Chrome is migrating to Manifest V3, which changes how extensions work — service workers instead of background pages, restricted remote code execution, and new permission models. AI tools sometimes generate Manifest V2 code that won't be accepted.
Permission minimization
Chrome Web Store reviews extensions for excessive permissions. Request only the permissions you actually need. AI tools often request broad permissions ('tabs', 'storage', 'activeTab') when narrower permissions would suffice.
Content Security Policy
Extensions must comply with strict CSP rules. No inline scripts, no eval(), no remote code loading. AI-generated code sometimes violates these rules, causing the extension to fail silently.
Data privacy
Extensions that access browsing data must have a privacy policy, explain what data is collected, and handle it securely. Chrome Web Store requires this disclosure for approval.
Cross-browser compatibility
If you want to publish on Firefox, Safari, and Edge too, your extension needs to handle API differences between browsers. AI tools usually target Chrome only.
What we check in your Claude Code chrome extension
Common Claude Code issues we fix
Beyond chrome extension-specific issues, these are Claude Code patterns we commonly fix.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Edge cases in complex logic
While Claude handles the main flow well, complex conditional logic sometimes has edge cases that produce incorrect results with unusual inputs.

Frequently asked questions
Can I build a chrome extension with Claude Code?
Claude Code is a great starting point for a chrome extension. It handles the initial scaffolding well, but chrome extension apps have specific requirements — manifest v3 compliance and permission minimization — that need professional attention before launch.
What issues does Claude Code leave in chrome extension apps?
Common issues include: over-permissive cors configuration, missing rate limiting, over-engineered abstractions. For a chrome extension specifically, these issues are compounded by the need for manifest v3 compliance.
How do I make my Claude Code chrome extension production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Claude Code-built chrome extension apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
