Which type of PaaS does not contain any license or technical dependencies on…

PaaS (Platform as a Service) offerings are commonly classified into four types based on how independent they are from any specific SaaS (Software as a Service) product: Add-on development facilities, Stand-alone development environments, Application delivery-only environments, and Open Platform as a Service. The defining question for each type is whether it needs a particular SaaS application to exist, and whether it hands the developer a full build-test-deploy toolchain or only a deployment channel.

A stand-alone development environment carries no licensing, technical, or financial dependency on any specific SaaS application or web service -- it is a generalized platform that runs as its own independent entity for a given function. That is exactly the property the question asks for, so Stand-alone development environments is the correct type.

• Add-on development facilities extend an existing SaaS product and usually require a subscription to that same co-resident SaaS application -- the opposite of having no dependency on a specific SaaS application.

• Application delivery-only environments hand the consumer only deployment and configuration control over an already-built application; they skip development, debugging, and test tooling altogether, which is a different distinguishing feature from SaaS independence.

• Open Platform as a Service supplies open-source software so a provider can host and run applications on its own infrastructure; its defining trait is the openness of the software stack, not the presence or absence of a SaaS dependency.

Re-reading the four categories against the question's exact wording -- no license or technical dependency on a specific SaaS application -- only the stand-alone category satisfies both halves of that condition, confirming the answer.
