Svelte app built with Cursor? Let’s review it.
Expert code review for Svelte apps built with Cursor. We find Cursor-specific bugs, fix Svelte security issues, and optimize performance. From $19.
Cursor issues we find in Svelte projects
Problems specific to Cursor's code generation patterns when building Svelte apps.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.
Svelte issues we check for
Common Svelte problems that affect production readiness.
Unprotected SvelteKit server routes
SvelteKit +server.ts endpoints without authentication checks. Since these look like regular files in the routes folder, AI tools often forget they're publicly accessible API endpoints.
Sensitive data in load functions
Server load functions returning sensitive data that gets serialized to the client. Everything returned from +page.server.ts load is visible in the page's HTML source.
Store subscriptions causing memory leaks
Manual store subscriptions ($: syntax works in components, but manual subscribe() calls in modules need explicit unsubscribe to avoid memory leaks).
Missing form validation
SvelteKit form actions that process submitted data without validating fields, types, or sizes — trusting whatever the user sends.

Frequently asked questions
Can you review Svelte code generated by Cursor?
Yes. We regularly audit Svelte projects built with Cursor and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Svelte issues does Cursor typically create?
Common issues in Cursor-generated Svelte code include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. Combined with Svelte-specific concerns like unprotected sveltekit server routes and sensitive data in load functions.
How do I make my Cursor Svelte project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Cursor-built Svelte projects, the typical path is: fix security gaps, address Svelte-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Cursor-generated Svelte 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.
