Rivet is an open-source no-code tool that was specially developed for the visual programming of AI agents with large language models (LLMs). In a graphical, node-based interface, users can create complex prompt graphs and execute them directly in their own applications. Of particular note is the ability to debug and observe the AI agent graphs in real time, which simplifies troubleshooting and optimization. Rivet also promotes teamwork, as the graphs can be saved as YAML files and managed in version control systems. This tool is developed and deployed by Ironclad Research and aims to help teams effectively design and implement more complex AI-based processes.
