Flowise
Explains what Flowise's canvas is good for: why dragging agents, tools and retrieval steps into a diagram lowers the entry barrier, when a growing project makes it hard to maintain, and when prototyping still pays off.
Flowise is an open-source visual builder that lays agents, tool calls and retrieval chains out as a node graph, so wiring replaces much of the code. The entry barrier is low: for demos, proofs of concept and internal prototypes, a diagram shows whether a chain connects faster than any configuration file. The trade-off arrives as a project grows, when dependencies and variable flows tangle and the canvas turns hard to maintain.
