JSF: 28 projects with 3% market share growth over 90 days

JSF is a framework for developing user interfaces in the Java environment and belongs to the Java EE family. It enables developers to create web-based applications with graphical components without requiring deep JavaScript or HTML knowledge. The framework abstracts the complexity of web technologies and offers a component-based architecture that simplifies the development of interactive web applications. By integrating with Java, developers can leverage established concepts of object-oriented programming.

Organizations seek JSF specialists primarily for maintaining and enhancing established enterprise applications. Typical tasks include creating user interfaces, integrating backend systems with frontend components, and optimizing existing JSF-based solutions. Freelancers with JSF expertise are particularly deployed in industries with older IT infrastructures for modernization projects. Work often focuses on adapting forms, implementing validation logic, and improving user experience.

Market data shows that JSF occupies rank 548 of 1233 skills with 28 projects, covering an established yet specialized segment of the IT market. The trend indicates positive development: with a 3 percent increase in market share over the last 90 days compared to the previous period, JSF records growing demand. This signals that despite the framework's age, there remains a need for professionals who can implement JSF projects and further develop existing systems.

Methodology: We count IT postings of the last 90 days that mention JSF. Projects posted several times that are detected as duplicates count once; postings without an assignable IT category are missing, so the figures are a lower bound. The trend compares the share of all IT postings with the 90 days before and only appears with enough comparison data. We do not show figures based on fewer than 30 data points. The rating “must have” or “nice to have” comes from an AI analysis of the posting texts. Distributions only refer to postings that state the respective attribute; we state the coverage alongside. The description of the skill is created automatically (from our skill directory or by AI) and checked by machine: no numbers, no company names, only the skill and its neighbours in the taxonomy. Texts are created and checked automatically, numbers come from the postings. An AI assigns the project type and role of each posting from its title, category and skills; the shares are counted postings, not estimates, and only appear with enough classified postings.
