Looking for options data with implied volatilities and the greeks. Aside from IVolatility or OptionMetrics, is there any other vendor which offers these kind of datasets?

My broker provide free real time IV and Greeks.

If you want historical data, they only provide free option prices data for up to 6 months. From which you have to calculate IV and Greeks using BSM yourself.
 
TradeHawk by Tradier offers real-time Greeks and Implied Volatilities (IV). In addition, we have Historical and IV studies in the platform displayed in both graphic and tabular formats.
 
Most of the EOD historical data services give you crappy jagged settlement curves whose IV levels are vulnerable to resting limit orders and inventory biases by the lead MMs. In order to get super smooth optimal EOD as well as intraday smiles and IV surfaces you need to record the market data yourself. Otherwise, you're often left with undesirable IV data with sometimes negative butterflies and calendars violating no-arbitrage conditions.

Nothing you can do about less than ideal old historical IV data, but you can improve current IV and greek market data, by diligently smoothing your vol curves when needed to represent the most objective, bias-free, "fair value" shape and slope when recording.

I can manually download data from my broker but how do I automatically download, say, data every hour?

Thanks.

Unless you have some market data recording application/algo, that is an expensive service you'll have to pay for.
