Cloudflare

Expert Cloudflare Code Review for AI-Built Apps

Cloudflare provides edge computing, CDN, DNS, and security services. AI tools deploy to Cloudflare Workers and Pages, but edge runtime limitations, configuration mismatches, and security header gaps are common in generated code.

Common Cloudflare issues we find

Real problems from Cloudflare codebases we've reviewed.

Deployment

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.

Security

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.

Bug

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.

Deployment

Worker size limits exceeded

Bundled Workers exceeding the 1MB compressed size limit due to large dependencies, preventing deployment.

Security

Misconfigured caching rules

Cache rules that cache authenticated responses or API endpoints, serving one user's data to another.

Security

Missing rate limiting

No rate limiting on Workers or API routes, allowing abuse of compute resources and inflated billing.

Cloudflare production checklist

Key checks before deploying your Cloudflare app.

Code uses only Web Standard APIs compatible with Workers runtime

deployment

Security headers configured (CSP, HSTS, X-Frame-Options)

security

Cache rules exclude authenticated and dynamic content

security

Worker bundle size within limits

deployment

Rate limiting configured on public-facing endpoints

security

KV operations account for eventual consistency

quality

Custom domain and DNS properly configured

deployment

Wrangler.toml configured for correct environment

Frequently asked questions

Can my app run on Cloudflare Workers?

If your app uses only Web Standard APIs (fetch, Request, Response, crypto.subtle), it likely can. If it relies on Node.js-specific modules, it needs refactoring. We assess compatibility and migrate your code to the edge runtime.

How do I deploy my app to Cloudflare Pages?

We configure your build settings, environment variables, custom domain, and security headers. For apps with backend logic, we set up Workers for API routes alongside Pages for the frontend.

Is Cloudflare cheaper than Vercel or Netlify?

Cloudflare's free tier is very generous and paid plans are competitive. Edge computing can reduce costs by serving content from locations closer to users. We help you optimize for Cloudflare's pricing model.

How do you secure a Cloudflare deployment?

We configure WAF rules, rate limiting, bot protection, security headers, and ensure caching rules don't expose private data. Cloudflare's security features are powerful but need proper configuration.
