Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

A reverse proxy takes all your web-based services, e.g.
and allows you to map these to domain names, so instead of typing
server.example.com:32400you can typeplex.example.com. I have simplified this quite a bit though - you need DNS configured as well, and depending on your requirements you may want to purchase a domain name if you intend on accessing content from outside your home without a self hosted VPN.Cloudflare is a DDoS mitigation service, a caching web proxy, and a DNS nameserver. Most users here would probably be using it for Dynamic DNS. You can use it in combination with a reverse proxy as a means to mask your home IP address from people connecting to your self hosted web-based services remotely, but on its own it cannot be used as a reverse proxy (at least easily - would not recommend attempting to). Do note that Cloudflare can see all the data you transmit through their systems, something to bare in mind if you are privacy conscious.
In my opinion though, it would be much better for you to use a self hosted VPN to access your self hosted services (can be used in combination with the reverse proxy), unless there is a specific need to expose the services out to the internet
Edit: fix minor typo, add extra info about cloudflare
So a reverse proxy is a way to manage subdomains? I read somewhere that it allows multiple different services to be hosted on the same port and I think I know that that is probably a lie.
Accessed from the same port.
Each service runs/listens on its own port, including the proxy (typically 80/443). When you connect to the proxy using its port, it will look at the domain name you used and proxy your connection to the port for the service that name is setup for.
So when you go to expose these to the network/internet, you only have to expose the port the proxy listens to and the clients only ever use that port regardless of how many services/domains you host.
