Open WebUI

Open WebUI is a comprehensive, self-hosted AI chat platform that brings the power of large language models to your own infrastructure with a beautiful, intuitive interface. Designed as a privacy-focused alternative to cloud-based AI services, Open WebUI supports multiple LLM providers including local Ollama installations, OpenAI, and any OpenAI-compatible API endpoints. With over 140,000 GitHub stars and an active community, Open WebUI has become the leading open-source solution for self-hosted AI interactions. The platform operates entirely offline when paired with local models, ensuring your conversations, documents, and data never leave your infrastructure—critical for enterprises, researchers, and privacy-conscious users handling sensitive information.

Common Use Cases

Enterprise & Development Teams: Deploy private AI assistants for internal documentation, code review, technical support, and knowledge management without sending proprietary information to external APIs. Use RAG to create AI-powered search across company wikis, codebases, and internal documents. Connect to multiple LLM providers simultaneously to compare responses and choose the best model for each task. Researchers & Data Scientists: Experiment with different language models, build custom prompts and tools, and create reproducible AI workflows. Use local models with Ollama for sensitive research data while maintaining the flexibility to connect to cloud APIs for specific tasks. Leverage web search integration and document analysis for research synthesis and literature reviews. Content Creators & Writers: Generate, edit, and refine content with AI assistance using multiple models simultaneously. Create custom prompts and tools tailored to your writing style and requirements. Use image generation for visual content creation and voice capabilities for accessibility. Privacy-Conscious Users: Run completely offline AI interactions with local Ollama models, ensuring conversations never leave your device. Build personal knowledge bases from documents, notes, and research with RAG capabilities while maintaining full control over your data.

Why deploy Open WebUI on Hostinger VPS

Deploying Open WebUI on Hostinger VPS provides a dedicated, always-available AI interface accessible from anywhere while maintaining complete control over your data and conversations. With VPS resources, you can run resource-intensive features like RAG document processing, image generation, and multi-model conversations without the performance limitations of shared hosting. The persistent volume ensures your conversation history, uploaded documents, model configurations, and custom prompts are safely stored with backup capabilities. Self-hosting eliminates per-query costs, rate limits, and usage caps imposed by cloud AI services—especially valuable for teams or individuals with high usage. For organizations with compliance requirements around data privacy, running Open WebUI on your own VPS ensures sensitive conversations and documents never leave your infrastructure. The flexible architecture allows you to connect to local Ollama installations on the same VPS for completely offline operation, or integrate with cloud APIs for specific use cases requiring the latest models. With Hostinger VPS, you can scale resources based on usage patterns, run multiple AI models simultaneously, and provide access to team members with role-based permissions. For developers, researchers, and enterprises requiring a powerful, private, and cost-effective AI platform, Open WebUI on VPS delivers ChatGPT-like capabilities with the control and customization that cloud services cannot provide.
