Open-source visual LLM workflow builder for creating AI agents and RAG applications without coding.
Why it matters now: Visual no-code builder for rapid AI agent and RAG prototyping, now backed by Workday.
Flowise is a drag-and-drop UI for building LLM applications visually, designed for rapid prototyping of AI agents and retrieval-augmented generation workflows without requiring programming knowledge. Originally founded as an indie project in 2023, Flowise was acquired by Workday in August 2025, reflecting enterprise validation while maintaining its open-source community edition under Apache 2.0 licensing.
The platform excels at simplicity and speed-to-prototype, though it offers fewer production-grade features than Dify for scaled deployments. Recent v3.x updates focus on multi-agent orchestration (AgentFlow architecture) and observability improvements, positioning Flowise as the ideal choice for teams prioritizing rapid iteration and straightforward AI agent deployment over comprehensive platform consolidation.
Node.js 18.15+ or 20+; 4 GB RAM recommended for building from source; SQLite or PostgreSQL database.
