A: Hi Diane,
surely, you can host your website on Netlify, or Vercel or any other provider which runs Node.js for the build process.
As for Flotiq, really I think you should choose which platform you prefer to create content. It's true that you can also get data from any headless CMS and use it in React Bricks, but for a new project it's much better to choose just one CMS not to add too much complexity.
