What is the best/ cheap hosting for portfolio and multiple projects under one hosting? I need advice . I was thinking about using namecheap.com for the domain but what would you recommend for hosting?

Use glitch. Its free to use for small projects.

OFC it depends upon how much load you want to handle

@py2js what’s glitch?

It's a hosting provider

How cheap? What technologies?
Anything that needs python, node, ruby, non pho or .net, will be very limited if free or cheap.

I would recommend vultr for cheap VPS (scalable)
There are also shared hostings for php and static stuff that are about 20 USD with unlimited (reasonable) storage/usage like stackcp, ecowebhosting (I resell this one)

I use Vultr combined with ServerPilot.io - makes it easier to administer.
