Building a chrome extension with Next.js? Let us review it.
Expert code review for chrome extensions built with Next.js. We fix Next.js-specific security gaps, optimize performance, and handle deployment. From $19.
Common Next.js issues we find
Real problems from Next.js codebases we've reviewed.
Unprotected API routes
Next.js API routes and server actions without authentication checks, allowing anyone to call them directly.
Server action data exposure
Server actions that return sensitive data to the client or don't validate user permissions before modifying data.
Incorrect middleware configuration
Auth middleware that doesn't cover all protected routes, uses wrong matchers, or can be bypassed with URL manipulation.
Missing ISR/SSG configuration
Pages that should be statically generated are server-rendered on every request, causing unnecessary load and slower responses.
Chrome Extension challenges to solve
Key chrome extension concerns that AI-generated code often misses.
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.
What we check
Key areas we review for Next.js chrome extension projects.
Manifest V3 compliance — service workers, permissions, CSP
Permission minimization — only requesting what's needed
Content security — no eval(), no inline scripts, no remote code
Data handling — privacy policy, secure storage, no unnecessary collection
