heroku-buildpack-python VS create-react-app-buildpack

Heroku also provides a platform as a service https://www.heroku.com/python

There are plenty of ways to host a server. Some are easy: - https://www.pythonanywhere.com/ - https://www.heroku.com/python

Set the latest Buildpack, so you get the fix that's not yet in the latest release: heroku buildpacks:set https://github.com/heroku/heroku-buildpack-python.git

I would not recommend this for someone who wants to deploy to Heroku since it looks like poetry still is not supported with default build pack

Biildpacks can specify add-ons in their bin/release which Auto get added for an app's first deploy. As an example check our the python buildpacks https://github.com/heroku/heroku-buildpack-python/blob/main/bin/release

If the calculations are done in Python, you will need a web host that lets you run a Python interpreter. I don't know of any completely free ones like GH Pages, but paid ones are https://www.pythonanywhere.com/ and https://www.heroku.com/python. Heroku does have a free tier which you could look into, until the site gains more traffic. I am not affiliated with either site.

Have you checked out https://www.heroku.com/python ?

I am currently hosted on platform.sh and am a big fan. Before choosing them, I also considered PythonAnywhere and Heroku but I ultimately chose Platform.sh because of the simple pricing and infrastructure configuration.

Dead simple to setup and get going. Heroku is another alternative.

I just started learning React and have been deploying to Heroku since it has worked the best in the past. I saw that the most popular build pack will soon no longer work as Heroku is upgraded. What does this mean for the future of React projects on Heroku?

Once you click add buildpack, it displays a pop-up on the dashboard. Paste this link in the Enter Buildpack URL and click on save changes. That is all you have to do.

the 405 is being thrown by the nginx reverse proxy that's run as part of the community create-react-app buildpack for heroku. I haven't dug in deeply but I'm assuming you're using this and that'd be the place to start. there's some noise about 405s being 'disallowed' for builds using Heroku's static buildpack (which this one does), but I have no idea why, how or if that's actually the case. good luck

I'm not sure you need a dyno for React as it runs in a user's browser. You just need a way to serve the JS to your user. After a quick google search I found this article and this Heroku buildpack. Good luck
