My first real LangChain agent came out of Flowise and I have some affection for it because of that. The visual node editor is genuinely satisfying when it clicks. You can see the whole chain, the memory, the tool calls, laid out in front of you. For someone trying to understand what's actually happening under the hood, it teaches while you build.
The component library has grown a lot. Vector stores, document loaders, conversational memory, most of what you'd want for standard agent work is there. The community has filled in a lot of gaps too. I've found custom nodes for things I assumed I'd have to build myself.
Where it starts to fall apart is production. Running Flowise reliably at scale is an infra problem the tool doesn't really help you solve, and a couple of version upgrades introduced breaking changes that cost us a morning to sort out. It feels like a product that was built to make the building experience great, and then the production deployment question came up later. For internal tools and prototyping it's hard to beat. For something that needs to run cleanly at enterprise scale, you're going to hit the ceiling.
