Built-in durability: Introducing Workflow Development Kit
Vercel just shipped the plumbing that AI agents need. Durability as a language feature—no message queues required.
Why it matters
Vercel's Workflow Development Kit removes a critical friction point for AI agent builders by baking reliability into the framework itself, lowering the barrier to shipping production-grade autonomous systems.

Publisher excerpt: Building reliable software shouldn't require mastering distributed systems. Yet for developers building AI agents or data pipelines, making async functions reliable typically requires message queues, retry logic, and persistence layers. Adding that infrastructure often takes longer than writing the…
