I have been using Stack Modifier since it was released on umod years ago and now run the paid version and what a must QOL plugin to have for your server. Not only does it allow you to easily adjust stack sizes, it also does a host of other important things that benefit the server and players. Khan is an awesome dev who will take the time to help anyone with issues they may come across, a true 5* plugin
Thanks

This plugin has actually helped me a lot as I did not really want to use stacksizecontroller as that is a lot more complicated.

Easy to use and saves a lot of precious time! Simple and clean UI, every admins wish.

Fantastic plugin very easy to use and understand, well worth the cost.

For months we were plagued with stack problems. We bounced around to every other plugin that all claim to do the same thing, but none were able to handle Epic Loot the way we needed it to. The ones that claim to, still have loop holes in them that will break stacks or even delete peoples items.

Stack Modifier by Khan solved all our issues.
Conveyors work, sorting works, fetching works.
It all works!

Now, it does take setting up. 
You MUST properly remove other stack plugins if you want to avoid any oddities.
If you have issues, find Khan and he will take care of it.

I regret not using this sooner!

Works perfectly and has a very dedicated developer. I hate editing stack sizes or editing new configs, it is just a chore that is made VERY easy by the UI with commands. Keep up the good work.

This is an amazing mod.  The UI makes it superfast and easy.  People complaining it is not free anymore :  think for 15 bucks, you know you're going to get the most up-to-date quality that this guy has to offer.  Thanks khan for making this and having it free as long as you did.  

I got used to Stack Modifier on another server and now that I host my own, it was the first plugin I knew I had to have.  I cannot live without it!  Khan continually updates and improves on this plugin and I feel it is worth 5 stars easily!  I thank the dev for all the hard work!  

Stack modifier does exactly what it says, but Khan keeps it updated and he's extremely responsive when you ask questions in support.  We had an issue that popped up, and he went back and forth with me for two days and the conversation included me sending some video of what was happening, and he absolutely nailed it, cranking out a few updates in a very short time that completely solved the problems.   Total props to Khan and to the plugin itself for being so very useful.

I was using Stack Extended, but this patch it was not working for recyclers, so I sought a replacement. I picked this plugin to give a try.  It was trivially easy to configure in the json (it does have a nice GUI too). It solved the issues with recyclers, and in my testing worked in all the containers on my server.  I am delighted to have this plugin.

The Stack Modifier Plugin is an absolute must-have for Modded Server owners.
We used the free version for several years, but now we've upgraded to the Premium version and we're not disappointed at all.
Transferring our settings was extremely easy - just top-notch!
The Premium version offers additional features and an enhanced experience, which makes us very satisfied. It saves us a lot of time and effort in managing item stack sizes on our server. The seamless integration and straightforward configuration have convinced us.

We're glad we made the switch to the Premium version and highly recommend the Stack Modifier Plugin!


UPDATE | 01.10.2024
We’ve been experiencing recurring minor issues with the custom items for several updates now. Communication with the developer was often one-sided, and other developers had to adjust their plugins to this. While we were able to fix the issue for a while through our own code optimizations, we’ve grown tired of it and have now switched to an alternative.

We’ll see how it developed over the next few months, but there might still be conflicts with other plugins when using custom items, even though the plugin itself works flawlessly.

That said, I can still recommend the plugin, as the support is really good.

Since we switched due to the ongoing issues, I’m deducting one star from the plugin.

This plugin is a game changer regarding stacking items. The simplistic UI and user-friendly design are really well-made and easy to use.

Changing the stack size limits of items has never been easier than with this tool.

After I have been satisfied using this tool for quite some time, I highly recommend this great plugin

After using another mod for handling stack modifications, I must say; this one is my favorite.

The ease of use and clean UI make for a quality plugin. Appreciations for keeping it updated!

I just upgraded from the Free Version on Umod to the paid version and was worried it would be a pain to update with my 10 servers but it was a super smooth process. The auto updater did wonders and even fixed any incorrect stack sizes. I'd definitely recommend this Plugin 10/10 for the ease of use and upgrading.

Definitely the best Stack Modifier plugin.

**Edit** Editing my review to 3 Stars as I know 1000s of server owners use this plugin and the free version received an update way before the paid version here. This devs plugins could have simply been tested on a test server and the update could have been sent out before the server update. If you have this amount of sales on a plugin it deserves updates before the forced wipe tested and sent out and an active dev or have the dev have another dev friend push an update for such an important plugin.

Thank you for the reply, with more timely fixes this would be great. But I see where you are coming from for people who auto update.

Converting a free plugin to a paid one, which doesn't have support on wipe day is pretty frustrating. I have a lot of upset players regarding the lack of this most recent update. Modified/multiplied servers truly depend on this plugin. It's disappointing that the initial free version which was taken over by a third party has faster support/updates than the OG developers paid version at its current stage.

I normally love this plugin but the dev is really slow to update on force wipes..
