Looking at How Replit Agent Handles Databases

The Replit Agent, a feature within the Replit development environment, allows users to offload coding tasks by interacting with AI through natural language prompts. This automation is particularly useful when working on full-stack applications requiring consistent changes between code and database schema. The Replit Agent can implement end-to-end features in an application, modifying API, Database, and Frontend simultaneously. It provisions a serverless Postgres database (powered by Neon) that scales on demand and builds the rest of the app using Flask, a Python microframework for web applications. Alembic, a database migration tool, is used to track changes in SQLAlchemy models and automatically generate migration scripts for schema updates.
