Flowise

Pros: Flowise is great because it makes AI workflow building feel much more tangible. Instead of writing every integration from scratch, you can visually connect models, tools, retrieval, memory, and agent steps on a canvas.

I like that it is open source and still developer-friendly. You can move fast with the visual builder, but you are not completely trapped in a black box because Flowise also offers API, CLI, SDK, and deployment options.

The agent and chatbot use cases are especially strong. Flowise works well for building RAG apps, internal AI assistants, support bots, multi-step workflows, and prototypes that need to become real products.

Cons: Flowise still needs careful setup if you are putting it into production. Visual builders make things easier, but they do not remove the need for testing, monitoring, permissions, version control, and security.

Overall: Flowise is one of the most practical tools for turning AI ideas into working agents and LLM apps without getting buried in boilerplate. It is approachable enough for fast experimentation, but flexible enough for serious builders. For teams working on AI assistants, RAG workflows, and agent prototypes, Flowise is absolutely worth using.
