Vercel Workflow SDK Turns Async Code Durable

Its strongest idea is making durability a property of ordinary async code instead of forcing developers into visual builders or workflow-specific DSLs. The trade-off is that compiler conventions and platform abstractions can make the system feel less transparent than traditional orchestration tools.

• –`use workflow` and `use step` compile application logic into isolated, replayable units with recorded inputs and outputs
• –Awaited webhooks make human approvals and third-party callbacks natural parts of a workflow
• –Durable sleeps pause execution without consuming compute, fitting multi-day agents, onboarding, billing, and RAG pipelines
• –The open SDK supports Vercel-managed infrastructure, local development, Postgres, and custom “World” adapters
• –Compared with Temporal, it offers a friendlier TypeScript experience, but complex polyglot or highly customized workflows may still favor more mature orchestration platforms
