—Generated apps compile to React/Next.js and FastAPI under the hood
—One-command deployment with hosting, scaling, logging, and observability
—Enterprise options for on-prem/VPC, SSO/SAML, RBAC, and audit controls
—AI Builder that generates production-ready app code from prompts
—Generated code remains customer-owned and can be exported/self-hosted
—Strong fit for Python and data teams already working with Databricks/Snowflake
