n8n

n8n offers similar visual automation building to commercial tools but with an open-source core that can be self-hosted, which appeals to fashion tech teams wanting full control over customer data and API keys. Teams use it to build custom pipelines linking AI image or copy generation to internal systems, PIM platforms, or CRM tools, often combining several AI APIs in one workflow that would be awkward to replicate manually. Its node library covers most common apps, and custom code steps handle anything that isn't natively supported. Self-hosting requires some technical maintenance, so smaller teams often use its cloud option instead for a similar experience without the upkeep.
