n8n

n8n is a workflow automation platform for building integrations and automations across apps, APIs, and internal systems. It provides a visual editor for creating multi-step workflows, with the option to add custom code and handle complex data transformations.

Key Features

• Visual workflow editor with triggers, branching/IF logic, loops, and data mapping
• Large library of prebuilt integration nodes (HTTP/API, SaaS apps, databases) plus generic HTTP Request node
• Webhooks for event-driven automation and building lightweight API endpoints
• Code and scripting steps (e.g., JavaScript) for custom logic and transformations
• Credentials management for connecting services securely
• Scheduling and polling triggers for time-based or interval automations
• Execution history and tooling to debug runs and inspect data
• Queue/worker execution mode for scaling and isolating job processing

Use Cases

• Sync data between CRM, spreadsheets, and databases with transformations
• Automate support/ops workflows (ticket enrichment, notifications, escalations)
• Build internal integrations using webhooks + custom logic without a full app

Limitations and Considerations

• Some advanced capabilities (e.g., certain governance/enterprise controls) may depend on paid offerings
• Complex workflows can require careful error handling/retries design to be resilient at scale

n8n fits teams that want an approachable low-code automation tool while keeping the option to write code for edge cases. It is commonly used to replace ad-hoc scripts and brittle point-to-point integrations with observable, reusable workflows.
