How it works
The platform supports many LLM providers and vector stores, and it can be self-hosted for free or used through Flowise Cloud. Templates cover document Q&A, customer support, and multi-agent workflows, which helps new users get a working bot running in minutes.
One caution: public development froze in July 2026 and the GitHub repository was archived in August 2026, so the open-source project is no longer actively maintained, although the cloud service remains live. A free cloud tier covers 100 predictions a month, and paid plans start at $35 a month.
