You get an error in the console when not using an API-key for google-APIs such as maps. You should probably get an API-key since it is free before you have 25.000 views/day. Secondly you should probably get an API-key in order to future-proof your website since google will probably, once the market is well established, require you to have a API-key what so ever.
