Cloudflare app built with v0? Let’s review it.
Expert code review for Cloudflare apps built with v0. We find v0-specific bugs, fix Cloudflare security issues, and optimize performance. From $19.
v0 issues we find in Cloudflare projects
Problems specific to v0's code generation patterns when building Cloudflare apps.
No backend or API integration
v0 generates frontend components only. There's no database connection, API routes, authentication, or server-side logic — all of which need to be built separately.
Static mock data instead of real data
Components use hardcoded mock data for display. Connecting them to real APIs requires significant additional work to handle loading states, errors, and data fetching.
Components not connected to state
Interactive elements like forms, filters, and toggles look correct but don't actually do anything. State management needs to be wired up manually.
Accessibility gaps
While v0 uses shadcn/ui (which has good a11y defaults), custom components sometimes miss ARIA labels, keyboard navigation, and focus management.
Cloudflare issues we check for
Common Cloudflare problems that affect production readiness.
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.

Frequently asked questions
Can you review Cloudflare code generated by v0?
Yes. We regularly audit Cloudflare projects built with v0 and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Cloudflare issues does v0 typically create?
Common issues in v0-generated Cloudflare code include: no backend or api integration, static mock data instead of real data, components not connected to state. Combined with Cloudflare-specific concerns like node.js api incompatibility and missing security headers.
How do I make my v0 Cloudflare project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For v0-built Cloudflare projects, the typical path is: fix security gaps, address Cloudflare-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review v0-generated Cloudflare code?
Our code audit starts at $19 and covers security, performance, architecture, and deployment readiness. For fixes, our Fix & Ship plan is $199. Larger projects get a custom fixed quote — no hourly billing or surprises.
