Flowise

Flowise is an open-source visual builder for AI agents and LLM workflows. Its canvas links models, memory, document loaders, tools, and other components into a flow that can be tested and integrated with an app. This makes the moving parts visible to people who find a long orchestration script hard to audit. It does not remove the need to manage credentials, model spending, or prompt-injection risk when tools can reach external systems. Start with a narrow workflow, capture failing examples, and check whether a flow is still understandable after several revisions. Hosted or enterprise service costs are separate from the self-hosted code.
