You can consider running a local Walrus network for testing purposes. This involves deploying a Walrus testbed on your local machine or utilizing a script available in the Walrus git code repository. Alternatively, you can utilize various SDKs provided for Walrus, such as the TypeScript SDK, to manage operations programmatically. For real deployment, you might want to look into operating or utilizing existing aggregator and publisher services which provide HTTP APIs. This option might help offload hosting burdens while still providing access to Walrus functionality.
