Absolutely, $50 lifetime license allows you to run the software anywhere you choose, firstly on your own hardware, secondly in VPS if you choose later.
https://gigme.io/pre-sale-details.htmlOnly real requirements for the beta are currently having an LND node running or being able to run one on the target machine including a full bitcoind node (LND does not currently support pruned modes on mainnet AFAIK). For the beta`docker-compose` needs to be installed to allow easy patch fixes.
The application itself runs as a very light-weight node.js API on top of the LND node via gRpc and static HTML / JS files that are served to the browser so no additional ram or storage requirements.
