I have developed a website in which the user just have to entered only text. one for name and another for comment. No login, No signup or no payment gateway. Currently I am hosting locally. my target audience is around 20-10000 people but might grow.

• Currently tech stack is Go + htmx + CSS.
• Since target audience is moderate, so planning to host it either on Vercel or Netlify based on the feature. ( Is there is a better option ? )
• Backend/Database: Firebase (Firestore) or Supabase. Both are easy to set up and work great. I am planning to store only text (two column one one as key and another as comment ) as and retrieve when needed.
• how to handle scaling?
• What about CI/CD?

What do you think?
