NextFlow — LLM Workflow Builder

About This Project

A visual DAG-based workflow builder for designing and executing multimodal LLM pipelines. Features a React Flow canvas, type-safe node connections, and a custom execution engine using topological sorting with parallel branch execution. Integrates Gemini APIs, Trigger.dev for async compute (FFmpeg, Sharp), and PostgreSQL for persistence. Supports import/export, execution history, and real-time node state tracking.
