Replit Postgres

Managed PostgreSQL database integrated into the Replit workspace, allowing developers to add persistent relational storage to apps without provisioning external infrastructure. Every Replit App includes a database by default with standard SQL access and connection via environment variables.

Replit Postgres provides 10GB free storage per app and tight integration with the Agent and workspace. Development databases run on Replit infrastructure with app-scoped connection strings that cannot be used by other apps, improving security over shared credentials. The service distinguishes itself from external managed Postgres by bundling an in-workspace SQL runner, Drizzle Studio for visual schema browsing and editing, and time-travel rollback to any Agent checkpoint.

Key capabilities:

• Built-in SQL runner and Drizzle Studio for running queries and visual schema management
• Time-travel rollback to restore the database to any Agent checkpoint
• 10GB free storage per Replit App for development databases
• App-scoped DATABASE_URL and connection credentials, not exposed publicly
• Separate development and production databases with deployment previews before publishing
• ORM integration with schema validation and SQL injection protection

Replit Postgres suits full-stack apps built in the platform, educational projects, and rapid prototyping with relational data. Agent can add the database, create schemas, and wire up ORMs to the app. Production databases support point-in-time restore and deployment previews, letting teams validate schema changes before affecting live users.
