When people talk about web development tools they typically mean the applications and software that allow web developers to test and debug the code and interface of a website or online application.
Technically, the phrase does not relate to tools that assist you in creating a website or app. However, such differentiation is ineffective. Web developers need a variety of tools that go beyond debugging and testing, such as a remote collaboration platform like Slack, a design tool like Fig ma, or simply a simple online forum like Stack Over flow.
