Open WebUI hosting on your own VPS
Open WebUI provides a browser-based interface for language models. On a dedicated Linux VPS the web interface remains continuously accessible and can be connected to external AI APIs, an existing Ollama endpoint or a separate GPU server.
The VPS plans compared here provide at least 8 GB of RAM and 50 GB of storage. This leaves sufficient headroom alongside Open WebUI for Docker, databases, user accounts, extensions and smaller local additional models. If you run just a single instance with few users and external model APIs, you may be able to get by with fewer resources depending on the configuration.
What is Open WebUI?
Open WebUI is a self‑hosted user interface for AI models. It enables browser-based chats and can integrate various model providers and OpenAI-compatible interfaces. Open WebUI is often used together with Ollama; however, the frontend and the actual language model do not have to run on the same server.
This enables two basic operating models:
- Open WebUI on a VPS with external AI: The frontend runs on the VPS while model computation is handled via an API or another model server.
- Open WebUI and local model on a server: The interface, for example, accesses a local Ollama installation. In this case RAM, CPU and, where applicable, GPU requirements increase significantly.
VPS or GPU server for Open WebUI?
Open WebUI itself does not require a dedicated GPU. A standard VPS is therefore the economical choice when models are used via external APIs or Ollama runs on a different system. You can also find suitable basics and other small AI setups in the Comparison for AI hosting on a VPS.
If language models are to be run directly on the same server, the model primarily determines the hardware. Small quantised models can run CPU-based on a powerful Ollama VPS. For larger models, low latency or multiple concurrent users, an Ollama GPU server is the more appropriate choice.
What level of server resources is appropriate?
For a comfortable Open WebUI installation with Docker, 8 GB RAM and 50 GB of SSD or NVMe storage are a sensible starting point. However, the number of users, enabled features and whether additional services are running on the VPS are the key deciding factors.
- RAM: 8 GB provide headroom for the web interface, database, embeddings and additional containers.
- CPU: Multiple vCPU cores help with document processing, parallel requests and background tasks.
- Storage: 50 GB is sufficient for the application and typical user data; local models or large knowledge bases require significantly more.
- Root access: It is important for Docker, reverse proxy, firewall and custom configurations.
- Backups: Chats, user accounts and configuration should be backed up regularly. Suitable offers are shown in the VPS comparison with backup storage.
Install Open WebUI with Docker
The official deployment is typically provided as a container. A VPS for Docker hosting simplifies updates, persistent volumes and separating it from other services. Before making it publicly available you should set up a reverse proxy, HTTPS, a firewall and secure authentication.
Anyone administering their own server for the first time will find the essential basics in the guide Setting up and securing a VPS. Open WebUI should not be accessible without protection via a directly exposed application port.
Open WebUI as a hub for AI workflows
The web interface can serve as a central access point to multiple models. For automated processes it can be combined with other self-hosted services. Those who want to build workflows and API actions in addition to chats can, for example, compare the offers for n8n hosting.
What to look for in a provider
- sufficient RAM and easily scalable resources
- SSD or NVMe storage as well as snapshots and backups
- root access and support for current Linux distributions
- Docker compatibility and a dedicated IPv4 or IPv6 address
- firewall, DDoS protection and a transparent server location
- sufficient bandwidth for multiple users and connected services
Conclusion: Cost-effective self-hosting of Open WebUI
A VPS with 8 GB RAM and 50 GB storage is a flexible foundation for Open WebUI when external model APIs or a separate model server are used. An expensive GPU is not necessary for the interface alone. Only when local language models need to run quickly on the same system is it worth looking at GPU servers and their available VRAM.
