- Low-coden8nn8n is a workflow automation tool with more than 400 integrations and dedicated AI nodes for agents, RAG and tool calls. You build flows visually and add JavaScript or Python code where needed. n8n is not open source in the strict sense: the source code is public but licensed under the Sustainable Use License (fair-code), which allows internal use and self-hosting but restricts reselling it as a service.View profile
- Low-codeGumloopGumloop is a no-code platform for AI automations with a drag-and-drop editor. Flows are built from blocks for data sources, LLM steps and outputs, for example for research, data preparation or reports. The vendor provides courses and templates, but more complex flows still require some ramp-up.View profile
- Low-codeStack AIStack AI is a visual platform that companies use to build AI agents for internal processes such as document analysis or knowledge search. The focus is on individual, well-governed agents with access controls and compliance features rather than multi-agent teams. Agents can be deployed as a chat interface, form or API.View profile
