Visual multi-agent workflow builders

A cluster of visual canvas tools for designing, orchestrating, and running multi-agent AI workflows, with features such as parallel execution, conditional branching, human-in-the-loop checkpoints, and real-time observability. The dated history before the index start is too thin to read a shape from, as only 4 dated entries exist. On traction, doop leads by a wide margin with 723 stars, followed by HarnessFOAM with 16 and epochflow with 12.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 18 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
