As vibe coding revolutionizes app development, security can't be an afterthought—it needs to be a core part of the creation process.
Recent Stanford research shows that developers using AI assistants wrote less secure code in 80% of tasks compared to those coding manually, while being 3.5 times more likely to overestimate their code's security.
And that's professional developers, we've seen an even more concerning trend among vibe coded apps.
At Replit, we don't just take this seriously, we build security into every app you create with Agent, by default—something Replit CEO Amjad Masad has called "the Pit of Success".
That's why our apps are secure, by default. We bake security in to the process of building with Agent—so you can focus on creating.
Built-in Security for the AI Era
Up to 40% of AI suggestions may contain vulnerabilities. At Replit, we've taken a unique approach: making security automatic and integrated.
Our platform is designed to prevent common AI-generated vulnerabilities like:
- Database vulnerabilities (SQL injection, validation)
- Exposure to common attacks (DDoS)
- Unencrypted communication (HTTPS)
- Exposed API keys (Secrets)
- Improperly structured apps
- Lost data due to a lack of version control
When you build apps on Replit, you get production-grade security features that protect against both traditional and AI-specific vulnerabilities.
Version Control
Never worry about losing your work again. Replit comes with native Git integration that automatically tracks every version of your code. Our built-in file history viewer captures every keystroke, giving you the confidence to experiment freely.
Need to go back in time?
Simply roll back changes or create checkpoints at critical milestones. When working with others, our secure collaboration features ensure everyone works in version-controlled environments. The integrated Git pane makes tracking code changes and navigating branches effortless—no command line required.
Encrypted Storage
When integrating third-party services like OpenAI or Slack into your application, you need API keys for authentication. Without proper security, leaked keys can lead to unauthorized access, data breaches, and unexpected charges.
Replit's built-in Secrets manager solves this by encrypting your sensitive credentials, keeping them separate from your code, and preventing accidental exposure while maintaining easy access for authorized applications.
This eliminates common security risks like hardcoded keys or .env file headaches, allowing you to focus on development rather than security concerns. Our management system, backed by Google Cloud's Secure Secrets framework, protects your sensitive data from accidental exposure.
Your API keys and credentials are stored as encrypted environment variables that only your app can access. We offer both account and team-level Secrets management, giving you flexible organization without compromising security.
Database Security
Agent handles all the database configuration automatically, ensuring protected connections from day one.
Agent also uses a special type of configuration, known as a "Object-Relational Mapper" or ORM. An ORM is a framework that makes adding databases to apps much simpler.
Best of all, ORMs protect against certain attacks on your database (SQL injection), so you don't have to worry about one of the most common security vulnerabilities.
Plus, with 7-day database version history, you can recover quickly if something goes wrong. Build with confidence using our production-grade Postgres databases powered by Neon.
Google Cloud Infrastructure
Your apps deserve enterprise-grade security from day one.
That's why all Replit deployments run on Google Cloud Platform (GCP), giving you world-class infrastructure security without the complexity.
We implement strict resource isolation between projects to keep your work protected, while Google Cloud Armor provides robust DDoS protection to keep your apps running smoothly even under attack.
Enterprise Security Features
Our platform is designed to meet information security compliance standards, giving you one less thing to worry about—Replit is fully SOC-2 compliant.
For organizations with advanced security requirements, we offer SAML single sign-on authentication. That means you can also integrate with your existing Identity Provider while implementing advanced group permissions and granular access controls.
Our Enterprise Platform also supports RBAC, which is like setting permissions on a Google Doc—it controls who can access what (and at what level).
For everything you create on Replit, "Private Deployments" offers a one-click toggle to make apps accessible to only your teammates.
Best Practices for Secure Development
Our platform makes security automatic, but here's how to make the most of it:
Store Secrets Properly
- Use the Secrets manager for API keys and credentials
- Never hardcode sensitive information
- Access secrets securely
- Manage secrets at account or team level
Manage Databases Safely
- Let Replit Agent handle database connections
- Use the built-in ORM for database queries
Build Secure Full-stack Applications
- Let Agent separate frontend and backend code clearly
- Ensure proper API route protection
- Use server-side code to handle sensitive operations
- Never expose internal API endpoints directly to clients
- Implement authentication middleware for protected routes
Why Replit Stands Out
While other platforms generate insecure code, Replit provides a comprehensive environment that guides users towards best practices.
