Every plan includes public IPv4 and IPv6, NVMe storage and a 1 Gbps uplink. Click one to reach the checkout with everything filled in.
How to size your project
Apps that call models over an API (OpenAI, Anthropic and others) need little server; apps that run the model on the server itself need a lot of memory and, without a GPU, answer more slowly. Size the plan by model size and number of users.

About Open WebUI + Ollama
Open WebUI is a ChatGPT-style chat you host on your own server, and Ollama runs open AI models such as Qwen, Llama, Gemma and DeepSeek right there. Together they make a local AI: you chat in the browser, with history and several accounts, and the models answer without depending on an outside API.
It works as a private AI assistant at work or at home: for summarising and reviewing text, drafting e-mails, querying internal documents through Open WebUI's knowledge base and trying open models before using them in a project. The same chat can also connect to OpenAI-compatible APIs.
With the model running on your VPS, questions and answers are processed right there, with no external AI API and no per-message charge: you pay for the server only. In the Belo Horizonte datacenter the data stays in Brazil; conversations with models from an external API, on the other hand, are processed by that provider.
At Master da Web, the VPS comes up with Open WebUI and Ollama from their official images, pinned to their versions, and the 1.5-billion-parameter Qwen2.5 model (qwen2.5:1.5b) already downloaded and set as the default: the first chat works with no key and no download, and the model speaks Portuguese, English, Spanish and other languages. Everything sits behind Caddy with HTTPS and an automatic certificate. The administrator account is created and tested before the page goes public, with open sign-up off: nobody registers before you do. The login (normally your e-mail) and the generated password arrive in the welcome e-mail and are kept in /root/open-webui.txt, readable only by root. Neither Open WebUI nor the Ollama API is exposed directly to the internet.
The plans have no GPU, so models run on the CPU. Small models, like the installed one, answer at an acceptable pace; larger ones need much more memory and run slower — Qwen2.5 7B, for example, is a 4.7 GB file that has to fit in RAM. To spare the CPU, the installation sets the context to 4,096 tokens, keeps one model loaded at a time and turns off the suggestions and tags generated after each answer. You add other models and external APIs in the admin panel.
