Has anyone tried using Drupal 8 for a domain name management and sales site

Having personally used Drupal quite a while ago, I will say that unless you plan to build multiple, complex sites...I would recommend sticking with something simpler, like Wordpress or whatnot. The learning curve to understanding and really building a good site with Drupel is pretty complex, unless they made it easier in 8...and for one site, I'm not sure if it is worth the effort for a simple domain site.

No I haven't. To me the first question would be whether all the modules you want are available in D8, if not, use D7 or wait till later. But if you want to create views of domains I certainly would want to use Drupal, not WP. But I always question whether it is worth setting up a domain sale site, when you think of the effort involved agains the possible return.

Why do you want multiple shops?

I've been looking at Drupal for quite a while now, and 8 seems to have a lot of the previous add-ons built into the core. I've also been playing with a lot of other type of CMS - WordPress, piwigo, SMF, WeBid, Uauctiuon, Abanti shop and several others. Most seem very vulnerable to spammers, and seem to require a fair bit of maintenance and updating. It seemed to me that Drupal gives me the chance to build a scalable and reactive site with a lot less effort. Once you accept the basic method that Drupal uses to store elements, and the way it structures pages, it doesn't seem to be as complex in Drupal 8 as it was in previous versions.

Why do I want multiple shops? I suspect the truthful answer is - because I can in Drupal 8. The domain market seems to be split into .com buyers, and buyers who are prepared to buy certain other selected TLDs. Having a few specialist shops for individual TLDs seems like a good idea, but I haven't thought it through, and I could be talked out of it.

@Kuffy. I thought about and did have multiple shops for .com, all other g & ccTLD's, and nGTLDs. In my opinion you are better having them in 1 website. And get any juice which might be had all in 1 website. A website with 50-100 domains doesn't provide a huge deal of confidence, IMHO. YMMV

Drupal 8 is not ready for a site like that, in Drupal 7 many modules you would need have coding errors and are not maintained (some of those modules I have fixed and I made a site fully functional so Drupal 8 too son not enough of the needed modules are ready if ported at all, Drupal 6 has everything too but 7 is better, Drupal 8 has some cool new stuff added to core, I personally like the fact all page requests run ajax but It has bugs. drupal 7 is also faster than 8 I would be willing to help anyone with a drupal site. Yes Drupal has steep learning curve but I have used it since 2009.

I installed Drupal 8.2.5 on my Brexit site to do a bit of experimenting. So far I've just got the standard theme, and a welcome message on there. I've been watching some You Tube tutorials before I move on. If I get to grips with that, then I'll have a go at a domain sales and info site.

I guess I don't fully understand what you mean by multiple shops. Do you mean multiple sellers each receiving payment direct? I looked at that in D7 and it looked like too much work for the result in my case. In D8 your only shop choice is Commerce which is complex but probably worth getting to grips with.

But in either D7 or D8 you can create views that would filter your domains how you want, for example by taxonomy term - so you could easily create pages (shops?) of a particular TLD etc. Or filter by price, age, etc. Or you could treat different domain extension as different content types, and still combine them into views if you wanted.

D8 is also by most accounts more demanding on hosting.

It was commerce that I was looking at. Drupal 8 is an enterprise level package, and the latest comerce package seems to allow the site to support multiple shops - presumabley the idea is that different geographic locations can have their own shops, but be interlinked through the main site. My idea was to have a separate shop for each TLD, as one of the primary search considerations for domain name buyers seems to be TLD. I'm hoping that it will allow keyword searches to run accross all shops if the prospective buyer requests it.

As I stated, I'm fairly early to this, and I'm still not sure how viable it is. Part of my interest is to get some Drupal site building experience, and part is to clear out some of my domain portfolio.

I'm also interested to know how many initial name searches take place in pubs and cafes, but I don't know how to research that.

too many things are possible in Drupal. I think I first installed Drupal around 2006, but didn't use Drupal for the last couple of years. I'm not a coder but created interested original websites on Drupal with modules. You can't add similar functionalities to a wordpress site with wp plugins. I think Wordpress is leaving the open source ideology with increasing number of "premium" versions of the wp plugins or the plugins which require sign up. Also, in general, wordpress plugins are less useful than Drupal modules. I'm considering to return to Drupal but don't have time and energy to learn the new version of Drupal and new modules.

You need to spend extensive time for searching on thousands of Drupal modules to create shops for each domain extension. Drupal is a complex CMS compared to wordpress. You might or might not find any useful Drupal module after spending too many days. Sometimes you may need to install multiple modules to create what you want. Good luck. Because you will need luck to find what you are looking for.

Drupal 8 seems to have quite a few of the modules included in the core. This seems to be a two edged sword. It makes it easier to use, but it can increase server loads. At the moment I'm exploring it's use for a Brexit information site, and I'm considering using it for a Bitcoin info site, so the domain site has gone onto the back burner. Since I discovered that the Name Silo marketplace has a Bitcoin payment option, I've decided that I'll use that to help with a bit of inventory pruning. The current problem with this results from having out of date registration details. I would have changed these after I moved the names to name silo, but I no longer have control of the email in the details, and changing that seems to block the transfer for a while.

Drupal requires less server resources than other CMS's. If you can't afford to rent a server you should avoid either using CMS (by using plain html site) or sites with high traffic. In fact a debian vps with 5gb ram+2 cores+120gb SSD+100mbps connection could handle very high traffic for multiple domains with Drupal.

You don't need to use namesilo nameservers to list your domain on their marketplace. If you are talking about changing registrant email on whois info, you need to change it before changing the registrar. If you can't access the email on whois you can't transfer your domain to another registrar. You can change all whois info at the current registrar.
