Ptero is a self-hosted chat client written in PHP and JavaScript that connects to various hosted LLMs like Llama, DeepSeek, and Mistral. It stores your conversation history entirely in browser local storage rather than on a remote database. You can run it standalone or embed the interface into a WordPress site using a shortcode.
It is worth a look if you want a clean, zero-signup way to test multiple models without wiring up a complex node stack. The catch is that while the interface is open source under the GPL v2, you still rely on third-party API providers for the actual model inference. Skip this if you need fully offline local execution or a Python-centric backend.
