Air-Gapped AI That Stays Private
Open WebUI runs entirely offline on your infrastructure. No data leaves your network. No cloud vendor locks you in. Deploy on disconnected networks and keep sensitive AI inference under your control.
Air-gapped networks prevent the internet from reaching critical systems. A computer or network isolated from unsecured networks has no connection to the public internet. Data moves only via physical media or secure channels. This design was born in defense, finance, and critical infrastructure. When you run AI on an air-gapped network, every inference stays private. No API calls phone home.
Why Open WebUI for Air-Gapped AI
Secure, offline LLM interface for air-gapped AI. The only enterprise self-hosted solution that operates entirely offline with zero external API calls.
Designed to Run Offline
Open WebUI includes explicit offline mode that blocks automatic model downloads. Pair it with local Ollama for inference that never leaves your network.
Enterprise-Grade Access Control
LDAP/Active Directory integration for military and government networks. SCIM 2.0 provisioning syncs users. Role-based access control with audit logging.
Flexible Architecture
Choose from 9 vector database backends, all on-premises. Encrypted SQLite or PostgreSQL. Horizontal scaling with Redis and load balancers.
Built for teams who need reliability
Deploy Air-Gapped AI in 4 Steps
From zero to private LLM inference on your infrastructure.
Choose Your App
Select an app to get started.
Deploy Open WebUI + Ollama Locally
Use Docker, Kubernetes, or bare metal. Both are open-source and require no cloud signup. Download container images to your air-gapped network.
Enable Offline Mode
Set HF_HUB_OFFLINE=1 in your environment variables. This prevents automatic model downloads. All models are pulled locally before network isolation.
Connect Your Data & Models
Upload internal documents to Open WebUI. Load fine-tuned models specific to your use case. All processing stays on your infrastructure.
Invite Your Team via LDAP or SCIM
Sync users from Active Directory or Okta. Assign roles and permissions. Enable audit logging for compliance.
Open WebUI vs. Cloud-Only AI
How self-hosted compares to ChatGPT and Claude for high-security environments.
ChatGPT and Claude are cloud-only. Open WebUI is self-hosted, all processing stays on your infrastructure.
Enterprise-Grade Features for Air-Gapped Deployments
Everything you need for secure, scalable on-premises AI.
Built for Regulated Industries
Open WebUI is designed from the ground up for defense, finance, and government.
GDPR Compliant by Design
All data processing on your infrastructure. Full control over data deletion.
Zero External Calls
In offline mode, no network requests during inference. LLM outputs never leave your network.
Enterprise Authentication
LDAP/Active Directory for government networks. SCIM 2.0 for automated identity management.
Audit-Ready Logging
OpenTelemetry integration sends logs to monitoring stack. Every inference recorded for compliance.
Scalable Infrastructure
Deploy on Kubernetes, Docker Swarm, or bare metal. Redis session store for horizontal scaling.
Frequently Asked Questions
Everything you need to know about air-gapped AI and Open WebUI.
Air-gapped AI is a large language model (LLM) that runs entirely on a disconnected network with no internet access. An air gap is a network security measure that physically isolates computers from unsecured networks, including the public internet. This prevents any data exfiltration risk. Air-gapped AI matters for defense, government, finance, and critical infrastructure because it keeps sensitive inferences private. No data is transmitted to cloud vendors like OpenAI or Anthropic. Your models, your queries, and your results stay under your control.
