VPS or Shared Hosting for a New Forum?

Hi, I’m about to launch a new discussion forum and need hosting advice.
Should I start with shared hosting or go straight to a VPS? How much RAM and bandwidth would a small but growing forum require?
Any reviews on Hostingsource.com or GTHost.com VPS hosting services? I’d love advice from experienced forum owners.

I’ve tried several hosts for smaller sites, but hostpro.com has been one of the most stable ones for communities and forums. My forum runs smoothly and I haven’t faced unexpected performance drops. Their support team helped me optimize PHP settings and recommended cache tweaks that noticeably improved speed. Upgrading bandwidth and RAM when needed was seamless. Overall it’s one of the more trustworthy hosts I’ve used.

For basic websites like small company pages or personal blogs, shared hosting with good storage speed can make a big difference. hostpro.com uses NVMe SSD drives and also keeps daily backups for about a month, so restoring files or the whole site is pretty straightforward.
