Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/changelog/post/2026-04-15-workflows-limits-raised/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

[Workflows](https://developers.cloudflare.com/workflows/) limits have been raised to the following:

| Limit | Previous | New |
| --- | --- | --- |
| Concurrent instances (running in parallel) | 10,000 | 50,000 |
| Instance creation rate (per account) | 100/second per account | 300/second per account, 100/second per workflow |
| Queued instances per Workflow <sup>[1](#user-content-fn-1)</sup> | 1 million | 2 million |

These increases apply to all users on the [Workers Paid plan](https://developers.cloudflare.com/workers/platform/pricing/). Refer to the [Workflows limits documentation](https://developers.cloudflare.com/workflows/reference/limits/) for more details.

#### Footnotes

1. Queued instances are instances that have been created or awoken and are waiting for a concurrency slot. [↩](#user-content-fnref-1)
