n8n
n8n is an open-source workflow automation platform that allows developers to connect various applications, APIs, and services through a visual interface using nodes. It enables the creation of complex automation workflows without extensive coding, supporting integrations with thousands of tools via built-in nodes and custom HTTP requests. The platform is self-hostable and offers both cloud and on-premise deployment options, making it versatile for different use cases.
Developers should learn n8n when they need to automate repetitive tasks, integrate disparate systems, or build data pipelines across multiple services, such as syncing data between CRM and marketing tools or triggering notifications based on events. It's particularly useful for scenarios requiring low-code automation, rapid prototyping of integrations, or when working in environments that prioritize self-hosted solutions over proprietary SaaS automation tools like Zapier.
