I'm not a target user but wanted to provide some feedback. As a customer, when I buy software I don't really care that it's open source or not and if you look in other threads on here, many people feel the same way. It's good marketing - especially for devs - but the whole point of someone paying you for hosting is so they don't have to do it ;)

I'd feature it less prominently as a selling point further down the page. As in: "btw, we're also open source!".

And I would drop the decimals on the pricing - take it from Patrick McKenzie[1]

The site looks really clean and wish you the best!
