How do you get a web app out quickly?

You could try my product/service :) (free account available) https://subzero.cloud
It goes like this:

• You spin up your database in RDS and define your schema (tables/views/functions/permissions)
• You create a subzero account and point it to your database, this will give you a Rest and GraphQL api
• Get a frontend up and running using React Admin https://marmelab.com/react-admin/. Here is a sample ReactAdmin frontend talking to a subZero backend https://github.com/scheiblr/ra-subzero-showcase

I'd say any framework your comfortable with, Rails / Flask / Laravel whatever.
Then Heroku (SSL / pipelines built-in) or Render to deploy, basically anything that allows you to simply "git push" to production.

And then for all the tooling, use as many SaaS products as possible in order to do as little work as possible for logging, analytics, payment/subscription management.

For example, don't implement subscription management yourself, use Stripe billing, or Recurly / Chargebee.

For domain we use namecheap.

@ilyastam what solution did you come up with for this?

If you want to get a web app out quickly, I'd say don't worry about automating the mundane tasks. Its not like deploying, setting up a domain, load balancing etc. even matters at the beginning. Just focus on what needs to get done to launch. You can deal with the rest of it later.

I use AWS with Python and React. And now I have an image that I just launch and can just git push to and it will be updated. But I only built that because I do a ton of new projects for new clients.

I'll say that https://www.netlify.com has been wonderful from this front. Easy to hook a domain up to, SSL, and a deploy pipeline are free out of the box.
