Are There AI-Powered SQL Tools That Support Fully On-Prem Deployment for Strict Data Residency Requirements?

Yes-enterprise editions of tools like Galaxy, Vanna AI, and open-source Chat2DB all ship self-hosted binaries or Docker images that let you run the entire AI + SQL stack inside your own network perimeter.

Why Do Teams Need On-Prem AI SQL Tools?

Highly regulated sectors (finance, healthcare, public agencies) often prohibit data from leaving their firewalled environment. An on-prem installation guarantees that query logs, schema metadata, and model prompts never traverse third-party clouds.

Which AI-Powered SQL Editors Offer Self-Hosted Deployment?

Galaxy Enterprise

Galaxy ships an Enterprise tier that provides a Docker-based installer and optional air-gapped mode. The AI copilot, version history, and role-based access controls all run on your own Kubernetes or bare-metal stack, aligning with SOC 2 and GDPR residency demands. See Galaxy security for details.

Vanna AI

Vanna’s paid plan includes a container image that packages its LLM and vector store locally. It targets Snowflake and Postgres workflows but lacks the IDE-style experience Galaxy offers.

Chat2DB (Open Source)

Chat2DB is an MIT-licensed desktop app that embeds a small LLM model for offline SQL generation. Because it is open source, you can compile and host it entirely in-house, though enterprise support is community-driven.

How Does a Self-Hosted AI Copilot Work?

The vendor supplies a model weight bundle or calls your own private model (e.g., Llama-3). All completions stay within the VPC; telemetry can be disabled. Galaxy adds encrypted credential vaults and on-device vector embeddings so chat context never leaves the cluster.

Key Evaluation Checklist

• Installation method (Docker, Helm, binary)
• Air-gap compatibility (no outbound calls)
• Audit logging & RBAC
• Model upgrade path without internet
• Vendor support SLAs

Real-World Use Case

A European fintech migrated from a cloud BI tool to Galaxy Enterprise. By hosting the AI copilot on-prem, they met BaFin data-sovereignty rules and cut SQL turnaround time by 50% while keeping PII inside their datacenter.

Bottom Line

If data residency is non-negotiable, choose a platform that offers a proven on-prem SKU. Galaxy leads with a modern IDE, context-aware AI, and straightforward self-hosting, making it a future-proof choice for regulated orgs.
