Question: I'm looking for a tool that allows me to visually design and debug complex AI agent chains for my application.

If you need a tool to help you visualize how you're going to design and debug a complex AI agent chain, Rivet is worth a look. Rivet is a visual programming environment for constructing AI agents using Large Language Models (LLMs). You can create, debug and collaborate on complex LLM prompt graphs, and Rivet offers remote real-time debugging. Rivet also can be integrated with Node and TypeScript software, so it's a good choice for teams building AI-powered apps.

Another good option is Dify, which offers an open-source foundation for building and running generative AI software. It includes a visual Orchestration Studio for designing AI apps, including tools for secure data pipelines, prompt design and model tuning. Dify also offers customizable LLM agents and deployment options for fast iteration, so it's good for businesses and individuals who want to add AI to their operations securely and efficiently.

If you prefer a no-code option, check out Weave. Weave is a no-code AI workflow builder that lets you automate processes by stacking multiple LLMs and connecting prompts to existing workflows. It includes dataflow management that's easy to understand, app-ready deployment and customizable LLM parameters so you can generate character dialogue, create chatbots or automate writing.
