Vercel has launched Workflows, a new feature that integrates durable execution directly into application code, allowing developers to replace backend infrastructure with just two lines of code. By using the "use workflow" annotation in TypeScript functions, developers can streamline queue scheduling, failure retries, state persistence, and observability without deploying separate orchestration services. This innovation addresses the challenge of moving AI agents or backend tasks from prototype to production by consolidating orchestration and business logic within the application code. Since its public beta in October 2025, Workflows has processed over 100 million runs and 500 million steps for more than 1,500 customers. Key features include durable streams, default encryption, suspension and wake-up capabilities, and support for large payloads. The AI SDK v7 introduces `WorkflowAgent`, enhancing durable execution with tool calling and state management. The Workflow SDK is open-source, supporting self-hosted deployments, with community adapters for MongoDB, Redis, and Cloudflare in development. The upcoming Workflows 5 will add native concurrency control and global deployment infrastructure.
