Surprise! Heroku is hosted on Amazon Web Services and has been for many years.
If you have some technical ability you can try self-hosting https://dokku.com/ which is open source and free to use on hardware that you pay for.
“Powered by Docker, you can install Dokku on any hardware. Use it on inexpensive cloud providers.”
Pick a VPS host. https://www.eucloud.tech/eu-providers/vps-hosting
“Once it’s set up on a host, you can push Heroku-compatible applications to it via Git. They’ll build using Heroku buildpacks and then run in isolated containers. The end result is your own, single-host version of Heroku.”
The way you shared the links IS already the official Federated way to do it.
https://fedi.tips/what-are-original-pages-in-mastodon/ “Just copy and paste the page’s web address into the search box on Mastodon/Lemmy/etc, and it will make that post or profile appear within your own server where you will be able to interact with it directly.”
How would we use your link? We go to the search page. In your web browser, look for a search icon at the top right of the page. On mobile, you may need to open up a context menu to find the search icon. You can probably just go to https://yourservername/search and get the same search page.
Copy your link and paste it into the search box, then press on the Search button. To save time for the future, you can make a bookmark to the search page.
@[email protected] has an interesting suggestion for using a central server. One risk could be if the central server tracks users, then we would send everyone through an extra layer of tracking. Let us look at that server’s hosting.

It seems lemmyverse.link is hosted on one of the top tracking websites.

Maybe someone can point the person who runs that website at this thread and ask that person to migrate to a different host.
