## Availability
Turnstile is currently in open beta and available as a free tool for all customers.
Turnstile is available for free for unlimited use via our visible widget in [Managed](/turnstile/reference/widget-types/#managed-recommended) mode. An [Enterprise](/bots/plans/bm-subscription/) version is available for customers who need additional features like support.
A pay-as-you-go option for advanced features will be available in early 2024 for self-serve customers.
For the beta, customers are limited to 1 million calls to the siteverify verification endpoint per month per site. Customers who need additional requests can upgrade to [Enterprise Bot Management](/bots/plans/bm-subscription/).
\ No newline at end of file
Users can continue to access these advanced features below our 1 million siteverify request limit.
Cloudflare recommends [@marsidev/react-turnstile](https://www.npmjs.com/package/@marsidev/react-turnstile) when rendering Turnstile. We have deployed an implementation of the library and can confirm that it is safe to use and works as expected.
