The exponential growth and capillar diffusion of the Web are nurturing a no
vel generation of applications, characterized by a direct business-to-custo
mer relationship. The development of such applications is a hybrid between
traditional IS development and Hypermedia authoring, and challenges the exi
sting tools and approaches for software production. This paper investigates
the current situation of Web development tools, both in the commercial and
research fields, by identifying and characterizing different categories of
solutions, evaluating their adequacy to the requirements of Web applicatio
n development, enlightening open problems, and exposing possible future tre
nds.
