NEW "use workflow" for Next.js CHANGES everything (Workflow DevKit)

Vercel launched Workflow DevKit for Next.js, enabling developers to build complex backend workflows with steps, automatic retries, and human-in-the-loop approvals. The video demonstrates building a post publishing workflow with spam checking, enrichment, manual approval, and scheduled publishing. It compares Workflow DevKit with Inngest (Motion), highlighting Motion's additional features like Python support, easier streaming setup, infrastructure configuration options, and explicit cron job handling. Both tools simplify traditionally difficult backend tasks like background jobs, long-running processes, and queue management.
