Flowise has established itself as one of the most popular open-source platforms for visually building LLM-powered agents and chatbots, thanks to its drag-and-drop canvas built atop LangChain-style orchestration and support for 100+ models and vector stores. It's genuinely useful for prototyping RAG pipelines, multi-agent workflows, and chatbots quickly, and the open-source/self-hosted option makes it attractive to teams wary of vendor lock-in, while the hosted cloud tiers add convenience at a reasonable price. The free tier is more of a demo than a working plan, and while the visual approach scales well for simple-to-moderate flows, very complex agent systems can still get tangled, and self-hosting adds operational overhead that not every team wants to take on.
