Workflows
Build durable workflows & multi-step applications
Workflows is an execution engine built on Cloudflare Workers — to build applications that can automatically retry, persist state and run for minutes, hours, days, or weeks. No need to worry about scaling, managing infrastructure, or handling durability: Workflows takes care of it for you.

How do Workflows work?
State included
Every Workflow instance has its own built-in local database. State is automatically persisted and replayed: no need to run (or scale) complex database infrastructure.
Pay only for actual compute time
You are only billed while code executes. Waiting for third-party APIs or approvals costs $0, so bills are dramatically lower than duration-based platforms or self-hosted alternatives.
Just write code
Write code, test it, and use your favorite packages and API libraries — no custom DSL needed.
Human-in-the-loop
Build Workflows that can wait for events — approvals from a human, webhooks from a payment processor, or messages from a queue — with just a single line of code.

A durable execution engine to build multi-step applications
Workflows introduces a programming model that makes it easier to build reliable, long-running tasks, observe as they progress, and programmatically trigger instances based on events across your services. Workflows automatically retry, persist state, and run for minutes, hours, days, or weeks.

“
Over 10 million developers around the world rely on the npm Registry to download packages over 1 billion times a day. We invested in Cloudflare Workers to improve our global performance, and now with the Cloudflare Workers globally available key-value store (Cloudflare Workers KV), we can make performance improvements that used to be impossible. ”
Powerful primitives, seamlessly integrated
Built on systems powering 20% of the Internet, Workflows run on the same infrastructure Cloudflare uses to build Cloudflare. Enterprise-grade reliability, security, and performance are standard.
