LLM tool calling SPA Client

Lightweight single-page app for interacting with OpenAI-compatible APIs. It allows you to simulate simple agentic workflow with tool calling.

You can also use it to perform model safety tests by simulating situations dangerous to the operator.

Quick Start

Usage

Use static version on Github Pages or run the Docker image.

Testing tool calling

You can import some example tools to test how model will use them:
