Rivet

Rivet is an open-source visual programming environment for building AI agents and LLM workflows — you wire together nodes for prompts, conditionals, tool calls, and data transformations on a drag-and-drop canvas instead of writing prompt-chaining code. Built by Ironclad and available as a TypeScript library for embedding in your own app. Model-agnostic (OpenAI, Anthropic, Google), supports parallel execution, real-time remote debugging, and exposes any graph as an HTTP endpoint via `rivet serve`.
