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:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

hi everyone,

I was just about to self-host a Ghost blog but then was warned that my ISP might change my external IP address at any time, so I would need to pay for a static IP address.

Is that true?

(I'd not seen much about that in stuff I've looked up so far about self hosting)

I selfhost my blog without a static IP. You just need Dynamic DNS.

Keep in mind that your outbound bandwidth might be different from your inbound. I get 300mbps in, but only 5mbps out. It's not noticeable during normal Internet use, but as you start sharing content publicly, limited bandwidth becomes really noticeable.

Don't even need dynamic DNS. Just use ddclient to update your DNS record if your IP changes.

That's called dynamic DNS (it's the dd in ddclient).

Yes, but there used to be specific dynamic DNS providers or ones that advertised as that but you don't specify need those now.
