If you are building a small, ordinary website for yourself, organization, business etc you can most likely get by with the shared hosting. It comes in 2 price modes, free and paid. You can start with the free hosting and upgrade anytime with a 30 day money back guarantee, or remain on free and just purchase a domain and security certificate. I am personally on the business version of the shared hosting.
If you need more resources than a single website you can check out the semi-dedicated hosting. It is ideal if you don’t need a separate server since it is similar to the shared hosting.
If you’re going beyond both you should probably plan on a VPS server plan. Ideally I would use this for my WaaS based builder, well I can always upgrade when I’m ready and the $ starts to roll in after I’m out of debt.
