Low-code builders
visual and no-code agent builders
n8n-io/n8n n8n is the de facto leader for general-purpose visual agent builders because it pairs a production-ready low-code canvas with the largest integration ecosystem and self-hosting; before choosing, decide whether you need broad integrations and stability (n8n) or a smaller tool that targets privacy, a vertical workflow, multi-agent orchestration, or developer-first scaffolding.

Capability profiles
Six axes, 0–5 each. The shape tells you the strategy: a wide hexagon is a generalist, a spike is a specialist. Showing the 8 most established — the rest are in the full catalog.
Provides a visual low-code canvas plus custom code and 1,500+ integrations to build production-ready multi-step AI agents with self-hosting and no provider lock-in.
Provides both a managed, no-API-key hosted platform and an open-source self-hostable agent runtime with a visual builder and marketplace.
Integrated low-code workspace combining visual AI workflows, RAG pipelines, agent builders, and broad multi-provider model support that can be self-hosted.
Provides a visual low-code flow builder with built-in API and MCP servers to turn workflows into deployable tools.
An all-in-one, local-first no-code agent platform that bundles chat, agents, vector DBs, desktop and web deployments, and dynamic model routing—beyond libraries that only provide primitives.
A native C++/Qt6 single-binary finance terminal with embedded Python analytics, 100+ data connectors, and built-in multi-provider plus local LLM agent support.
An open-source, self-hosted platform that combines RAG, a workflow engine and MCP tool-use to build enterprise-grade agents supporting both private and public models.
A local-first visual AI workbench that produces editable artifacts (code, documents, websites, designs, videos) and lets agents plan, run tools, and modify files in-place rather than only returning chat transcripts or finished files.

Hosted alternatives
If running your own reviewer is more ops than you want, these managed services cover the same job.
The hosted side of Flowise: build the same visual agent flows in your browser and let Flowise run and scale them, so there is no container to deploy or update.
Try Flowise Cloud →Managed hosting for n8n's node-based automations with AI agent steps: the same workflows you would self-host, run for you with credentials and scheduling handled.
Try n8n Cloud →The hosted counterpart to open-source Langflow: drag-and-drop agent and RAG pipelines deployed on DataStax's cloud rather than a server you run yourself.
Try Langflow (DataStax) →
