For a newbie, Platform is the latest new kid on the Rapidweaver block: https://rapidweavercommunity.com/addons/stacks/platform
As a user of Both Foundry and Foundation, I’d say it’s better than both (purely personal opinion) and somewhat cheaper with the latest deal, $37.50 all in; no need to buy additional stacks bundles.
Details on the latest update here: Platform: release 1.1.3 has been published today 😀
The dev, @jay is on this forum.
If you fancy a challenge, there is also UIkit by @Lucas: https://rapidweavercommunity.com/addons/stacks/uikit it’s next level stuff, taking what frameworks like Foundry, Foundation and Platform does and going way way further. But, to get the most out of it you will have a learning curve and need a fair understanding of using css classes, so not perhaps best suited to a total newbie, but still worth considering. If you are serious about website production using Rapidweaver, UIkit is the one to go for. if you want something super easy to use but still plenty powerful, then Platform is the boy, in my opinion.
