About Replit

Replit operates an IDE-in-the-browser where millions of users build and deploy applications, with over 500,000 business users. The platform targets anyone from hobbyists to teams, removing friction from the traditional setup-and-deploy cycle by letting users describe applications in natural language and have the system generate and run the code. Core infrastructure runs on GCP and Kubernetes, with security tooling (HackerOne, Bugcrowd, OWASP) and incident-response processes integrated into the product workflow. Current focus areas include preventing infrastructure abuse (cryptomining, phishing deployments), scaling support for rapid user growth, and building enterprise governance and team collaboration features.
