# Use Web GUI

For those who want to quickly test out the functionalities of Randcast without having to set up a local Solidity development environment, we recommend the following steps.

Use our [Subscription Management Web Portal](https://randcast.arpanetwork.io) to:

* Create, fund, and cancel subscriptions.
* Add and delete consumer contracts for an existing subscription.
* View and analyze historical and pending requests and events.

***Note**:* Due to connection issues with RPC endpoint, Redstone Holesky Testnet and Taiko Katla Testnet are not supported yet.

Use [Remix](https://remix.ethereum.org/) to:

* Code, build, debug, and deploy your consumer contract.
* Request randomness via your consumer contract.

***Note**: A browser extension wallet is required. (We use Metamask in our examples.)*

In [the next section](https://docs.arpanetwork.io/randcast/getting-started/use-web-gui/subscription-management-portal), we will navigate you through the [Subscription Management Web Portal](https://randcast.arpanetwork.io) functionalities.

You can [jump to the Remix section](https://docs.arpanetwork.io/randcast/getting-started/use-web-gui/remix) for a step-by-step guide to customizing and deploying your consumer contract.
