Why we included this project

Rivet is a desktop editor for building AI agents and prompt chains on a visual graph instead of keeping prompt strings in code. You wire together LLM calls, text transformations, and control logic as nodes, then watch inputs, outputs, and responses stream past as each one runs. Built-in variation nodes let you A/B test prompts, and the debugger can attach to agents already running in production. Once a graph behaves, the companion TypeScript runtime runs that same project from inside your own application like a normal function call. It is an authoring and debugging tool rather than a deployed service, so it suits teams that want prompts they can see and edit instead of logic scattered through source files, and it supports several major LLM providers plus voice-data workflows.
