n8n

Workflow automation is the core of n8n, a platform that lets technical teams build and run AI agents and business processes. Teams can combine visual, no-code building with custom code when a workflow gets complex. Each step in a workflow can be opened to see what it does, which makes the automations easier to follow and hand off to other people. The platform connects to more than 500 native integrations, and any API can be reached through HTTP. It also supports MCP, so agents and coding assistants can plug in.

n8n offers human-in-the-loop approvals, audit logs, version history, and role-based permissions for teams that need oversight of AI actions. It can be self-hosted with Docker or on-prem to keep data in the customer's own environment, and the source code is available on GitHub. A hosted version is also offered. The company is n8n, and its listing describes case studies from companies including Huel and Vodafone.
