Flowise

Flowise is an open-source, low-code visual builder for LangChain-based LLM workflows and AI agents. Built on Node.js and TypeScript as a pnpm/Turbo monorepo, Flowise lets developers and non-developers compose chatflows, multi-agent agentflows, RAG pipelines, tools, and assistants on a drag-and-drop canvas, then expose them as REST APIs, embeddable chat widgets, or programmatic SDK calls. The project ships a self-hostable server, a React admin UI, a third-party node component library, an auto-generated Swagger UI, official TypeScript and Python SDKs, an embed widget, and a managed Flowise Cloud offering with metered prediction quotas. Flowise was acquired by Workday in 2025.

Flowise publishes 13 APIs on the APIs.io network, including assistants API, attachments API, chatflows API, and 10 more. Tagged areas include Agents, Agent Workflows, Artificial Intelligence, Large Language Models, and Low-Code.

The Flowise catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Flowise’s developer surface includes authentication, documentation, GitHub presence, pricing, signup flow, YouTube channel, and 19 more developer resources.

Kin Score Kin Score How this is scored →
scored 2026-09-08 · rubric v0.20.0
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/flowise: open an issue to ask a question, or submit a pull request to add artifacts.
