Performance for your Cursor-built Rust app
Expert performance for Rust apps built with Cursor. We audit Cursor-generated Rust code for performance issues. From $19.
Cursor issues we find in Rust projects
Problems specific to Cursor's code generation patterns when building Rust 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.
Rust performance issues we check for
Performance-specific Rust problems that need attention before production.
Excessive .clone() usage
AI tools clone data everywhere to satisfy the borrow checker instead of using references, lifetimes, or Cow — defeating Rust's zero-cost abstraction goals.
Blocking in async contexts
Using std::thread::sleep, synchronous I/O, or blocking mutex locks inside async functions, starving the Tokio runtime of worker threads.

Frequently asked questions
Can you performance my Cursor-built Rust app?
Yes. We regularly handle performance for Rust projects built with Cursor. We understand Cursor's code patterns and the specific Rust issues they introduce. Our review covers the full stack from frontend to backend.
What Rust performance issues does Cursor typically create?
Common performance issues in Cursor-generated Rust code include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. On the Rust side, we often find: excessive .clone() usage, blocking in async contexts.
