n8n
92 published cases mention this tool.
n8n is a visual workflow-automation platform that became the star of 92 cases once AI nodes entered the picture. Typical builds: a voice front desk answering dental-clinic calls, WhatsApp leads flowing into spreadsheets, invoice and refund pipelines, and a 52-node production workflow. The recorded limits are concrete: self-hosting plus multi-API integration takes effort, error handling is your own job, and one case puts API costs around $20–30/month.
