Unfortunately, Gnosis currently doesn't have the resources to run Gnosis Safe on Binance Smart Chain. However, Binance was able to deploy the Gnosis Safe smart contracts and fork the Gnosis Safe interface. You can read more about this in this announcement post.
As a result, Gnosis Safe is now available for the Binance Smart Chain at https://gnosis-safe.binance.org/.
As this is an unofficial version of Gnosis Safe, we cannot provide any customer support for Gnosis Safe on BSC. If you encounter any issues, please reach out to the Binance team.
