Alternative to Netlify and Vercel
Problem: Paying per user is getting expensive for a service that just hosts some static files.
It's not 2010 anymore so who wants to deal with nginx configs? Well luckily for you there's a couple great solutions
Essentially a 1 for 1 replacement for Netlify and Vercel, plus it has a great free tier and then goes up to $20/month for more concurrent builds. It has build previews for all your pull requests, GitHub integration and you can also get all the benefits of the Cloudflare ecosystem like DDoS protection, WAF, analytics and site optimization.
Firebase by Google Cloud
Similar set of features, but I would say it requires more configuration instead of everything being setup automatically. You'll need to setup your Cloud Build separately and then have the result deploy to Firebase's hosting. It also has deploy previews, and now you're part of the Google Cloud Platform with it's endless array of tools. Also comes with a great free tier and then goes to pay per use. This one will definately be your cheapest option unless you're getting some crazy high usage.
Hopefully that helped!
