Building a chrome extension with Cloudflare? Let us review it.
Expert code review for chrome extensions built with Cloudflare. We fix Cloudflare-specific security gaps, optimize performance, and handle deployment. From $19.
Common Cloudflare issues we find
Real problems from Cloudflare codebases we've reviewed.
Node.js API incompatibility
Code using Node.js-specific APIs (fs, Buffer, crypto) that don't exist in the Cloudflare Workers runtime, causing deployment failures.
Missing security headers
No Content-Security-Policy, X-Frame-Options, or HSTS headers configured, even though Cloudflare makes them easy to add via Workers or page rules.
KV storage race conditions
Cloudflare KV is eventually consistent. Code that reads-then-writes without accounting for propagation delays causes data loss and stale reads.
Worker size limits exceeded
Bundled Workers exceeding the 1MB compressed size limit due to large dependencies, preventing deployment.
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 Cloudflare 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
