I am looking for a better english expression or single word that describes this:

developer usabilty: the quality of language, tooling, IDE and APIs for frictionless development.

example usages:

The developer usabilty of our clould offering is very bad because our users need to know way to many details.

The developer usabilty of the APIs in that library could be improved because noone can remember these long names.

We are like Apple Inc. but for developers. We care deeply about the developer usabilty of our SDK.

A collocial term is OK, but it should be widely understood.

  • "Usability" is the correct word, for developer tools or a tool's other intended audiences. A quick google search for "developer usability" will show many white papers that simply use "usability". For instance, msdn.microsoft.com/en-us/library/ms997575.aspx.

  • "Usabilty" seems too tightly associated with graphical user interfaces.

  • It's not. It's the generally accepted term. It's frequently used to refer to APIs. A simple Google search will show that.

  • When I search for developer usability I get a lot of results related to "developers doing someting about the usabilty of their products". Like developers doing usability testing or developers that also do UI/UX design and such.

You may be looking for user–friendliness. The developers in question are users in this context.
Perhaps you can even adapt it as developer-friendliness to make it more explicit.


user–friendly adjective

: easy to learn, use, understand, or deal with : user–friendly software

  • user–friendliness noun




But Apple changed the game in 2008 with its developer-friendly App Store, which now hosts some 350,000 apps that have been downloaded over 10 billion times on the iPhone, iPod touch and iPad.

The San Francisco-based startup hosts all the computing functions of its web developer-friendly telephony service on Amazon Web Services, a business model that enables Twilio to differentiate itself even further from its voice API cohorts.


I think I may have just found a good candidate:

developer experience (DX)


Looks pretty canonical to me. It also is a good counterpart to user experience (UX).
