Replace Make.com and n8n with Claude Code Routines

Claude Code routines are proposed as a developer-first alternative to Make.com and n8n for workflow automation. Defined as plain Markdown files, routines run multi-step workflows via the Claude Code CLI with built-in AI reasoning, native Git version control, and no proprietary lock-in. A full feature comparison table covers cost, debugging, branching, and vendor lock-in. A hands-on tutorial walks through migrating a Google Sheets-to-Slack enrichment pipeline, including scheduling via cron and GitHub Actions. Cost analysis estimates ~$15–25/month for 5,000 runs versus $80–119 for equivalent Make.com or n8n plans. Key caveats: the routines subcommand is proposed functionality not yet confirmed in official docs, LLM inference latency (2–15s per step) makes routines unsuitable for real-time webhooks, and pre-built OAuth connectors are absent.
