We're excited to announce increases to the [Cloudflare Workflows](/workflows/) scaling limits for all accounts on the [Workers paid plan](/workers/platform/pricing/).

We've raised the [Cloudflare Workflows](/workflows/) account-level limits for all accounts on the [Workers paid plan](/workers/platform/pricing/):

* We have **more than doubled** the concurrency limit per Cloudflare account, from 4,500 to 10,000 Workflow instances. Note that each unique invocation of a Workflow is an **instance** of that Workflow.

* You can now also create up to 100 Workflow instances per second, raised from the previous limit of 100 Workflow instances per 10 seconds.

* **Instance creation rate** increased from 100 workflow instances per 10 seconds to 100 instances per second

Earlier this year, we launched our serverless durable execution engine, Workflows, into GA to help developers build long-running, multi-step applications on Workers. With Workflows, you can automate a sequence of idempotent steps in your application with built-in error handling and retry behavior.

Consider a practical example: your application offers a two-week free trial. When users sign up, you can trigger a Workflow to track their trial period and send timely reminders before it expires. This means running one Workflow per user, which previously meant hitting our hard limit at just 4,500 concurrent users in the onboarding flow.

With the new concurrency limit of 10,000 Workflow instances, you can support up to 10,000 customers simultaneously moving through onboarding. We've also increased throughput tenfold: you can now intake 100 new customers (creating 100 new instances) per second, up from the previous limit of 100 per 10 seconds.

These increases mean you can create new instances up to 10x faster, and have more workflow instances concurrently executing. To learn more and get started with Workflows, refer to [the getting started guide](/workflows/get-started/guide/).

If your application requires a higher limit, fill out the [Limit Increase Request Form](/workers/platform/limits/) or contact your account team. Please refer to [Workflows pricing](/workflows/reference/pricing/) for more information.
