Vercel Workflows

Vercel Workflows is a fully managed platform for building durable applications and AI agents in JavaScript, TypeScript, and Python.

It builds on the open-source Workflow SDK for JavaScript and TypeScript, and on workflow support in the vercel Python SDK to let your code pause, resume, and maintain state.

With Workflow, Vercel manages the infrastructure so you can focus on writing business logic. Vercel Functions execute your workflow and step code. Vercel Queues enqueue and execute those routes with reliability. Managed persistence stores all state and event logs in an optimized database.

Your workflows are:

• Resumable: Pause for minutes or months, then resume from the exact point.
• Durable: Survive deployments and crashes with deterministic replays.
• Observable: Use built-in logs, metrics, and tracing and view them in your Vercel dashboard.
• Write async JavaScript, TypeScript, or Python with familiar language primitives. No YAML or state machines.

Use a workflow when your logic needs to pause, resume, or span minutes to months:

export async function aiContentWorkflow(topic: string) {
  'use workflow';
 
  const draft = await generateDraft(topic);
 
  const summary = await summarizeDraft(draft);
 
  return { draft, summary };
}

Install the Workflow SDK package:

pnpm i workflow

Follow the Workflow SDK getting started guide to create your first workflow.

• Workflows and steps: Write durable functions with 'use workflow' and 'use step' directives.
• Sleep and hooks: Pause for minutes to months, or wait for external events.
• Observability: Track runs in real time, trace failures, and analyze performance.
• Streams: Stream data in and out of workflows with managed persistence.
• Skew Protection: Protect your workflows from version skew.
• Usage-based pricing: Pay only for Events, Data Written, and Data Retained.

Every step, input, output, sleep, and error inside a workflow is recorded automatically.

You can track runs in real time, trace failures, and analyze performance without writing extra code.

To inspect your runs, go to your Vercel dashboard , select your project and navigate to Observability, then Workflows.
