I think the comments criticising the pricing are wrong, you can't compare one generalist tool to another highly specialised tool. But on top of that comparing to Figma, Framer or other VC backed products is a mistake, these products are priced to capture market share and grow rabidly. They are clearly underpriced. I may be wrong but CSS Pro looks like a small bootstrapped product, pricing for market growth doesn't need to be the strategy. This is priced for sustainable development and supporting the developer on a small niche product.
If a developer/designer is using this 1 day in 5 then they can justify the subscription.
To those suggesting this shouldn't be a subscription, keep in mind that CSS is going through a period of rapid improvements, this enables them to add support for new features without having to either eat the cost on a sold product or charge for upgrades multiple times a year.
VC backed business setting low prices for rapid growth has unfortunately damaged the ability for small indie developers to price their products sustainably.
