Do Replit apps have rate limiting?

Replit does not provide built-in rate limiting for deployed applications at the platform level. This means any API endpoints or forms in your Replit app are exposed to brute force attacks, credential stuffing, and abuse without custom protection. Developers need to implement rate limiting manually using libraries like express-rate-limit for Node.js or similar solutions for other languages. Without rate limiting, a single attacker can overwhelm your application with requests or systematically test stolen credentials. UNPWNED checks bounded externally observable rate-limit signals; it does not prove application-wide enforcement.
