What does the term "custom application" mean to you?

I believe it can be either. You can have a custom application created, either in house or hiring it out. An Off The Shelf Software/Application can also become customized, so much that it it can't be upgraded to a new version because of all of the customization. In this case it is probably like a customized car, you might have bought the framework and done your own work on it so others could see it has been customized, (not just a trim selection.)

It can be either. Just a non-standard application.

Custom application means either home grown or a pre-built application that has the ability for the consumer to make changes to suit their needs.

To me the key word of custom is the defining element. Home grown is obviously custom, but when an application is purchased that has customer defined changes built in would be a custom application. The distinction would be something that is built specifically for the individual customer.

Custom application can be either.  Typically Home grown, but an off-the-shelf app can be so customized that is acts, and is supported by the vendor, as a custom one-off application.

A custom application is anything which is either developed from scratch or changed from its default state.   Example, SAP.   if you get it and keep it vanilla it is not a custom application.  But as soon as you make changes which affect its normal default process it  becomes custom.   There are special considerations for upgrading and patching.   Like @rschroeder said, they become more challenging to support.  I am not talking about making a Macro in Excel or a website per say, more along the lines of major applications, like and ERP or SolarWinds.  If you were to change the Database behind SW to make it do something you wanted, it becomes custom.

A "Custom Application" means, to me, something that is challenging to support.  There may be only one person who understands it because they wrote it.  If/when they leave the organization, that custom app is a liability waiting to bite a team, either through its failure, or through the inability to further modify it to meet new requirements.

In short, "custom app" often means "trouble".

But that applies to apps built outside of standards, and to teams that aren't properly staffed and funded.  There are many custom apps that have no problems, that are continually modified to meeting changing requirements, which we never hear about--because they were created according to standards, and their staff is properly numbered and funded for training and design.  They have enough depth that some people can change departments or even leave the company, and the app still is fully supported and retains utility and reliability.

"Custom App" may not only apply to something completely unique that was never "in the box."  It can be an application with a specific, targeted use case, and not be flexible enough to handle other needs.  Once upon a time, Excel was probably considered a "custom app" that was targeted solely at accounting types.  Then others realized it would be helpful for managing inventory, organizing people, planning changes--heck, I recently ran into a video about a fellow they call "The Michael Angelo of Microsoft Excel", who does Master quality art using Excel.  It's immediately obvious Excel left the realm of being a "custom app" generations ago.  But when it was new, I'm betting there were plenty of people who thought inside the box, and put unimaginative limitations on how they would be able to use Excel.

So there it is--"custom application" must have some flavor of "limited use" to it.  It solves only one kind of problem, or it has limited support, limited ability to be modified (or "de-customized") to serve other needs.  It's likely to have a narrow user base (if not, it would have been exposed to bright people who would have asked "why can't it do . . . ?", and then learned enough about it to make it serve other needs--or they'd drop it in favor of something more flexible).

There's nothing wrong with a custom app that fills a specific need well.  But apps become bloated when asked to do many things, to serve many needs.  (They might just even be hiding a version of Flight Simulator, making them far bigger and complex.  The moral of THAT story is to give credit where credit is due, and treat your employees as you'd like to be treated.)  For an app to remain "custom" in my mind, it has these kinds of limitations.

I actually think of custom app in two separate ways.

Customizable - Means its an app you take and make it look how you want. Much like Orion or SAP.


Custom built - An outside or inside team builds from the ground up, an app that suits pretty much just your organization.

These little gems keep me busy all the time!

I would call them differently as-named in the question

Home-grown application = In-house application
Customised pre-built applications = Just `Application` or customisable application (powerful tools like servicenow)
Custom Application in my head would probably be a small application probably built in house that lets you customise it (lots of control but one specific purpose) or maybe an Applet or Widget...a small add-on

An application that is designed to work on your organisation, A specialist feature, an example would be a Airport boarding card printer. This printer is designed and only used to print boarding cards used at airports. It can NOT print a word document on a A4 size of paper. Therefore it  'custom'

Another example for custom application would be an airline app for boarding, this would hold your boarding pass, flight miles/points, frequent flyer ID. This application is custom and cannot be used for News, Sports, Games, keeping fit, etc etc
