SonarQube, SonarCloud, and SonarLint are open-source products that have recently opened up product portals on Productboard to showcase their current features, recent releases, and planned features. The portals also include an "Under Consideration" tab where users can provide input on unconfirmed or uncertain feature ideas, with voting options of Nice-to-have, Important, and Critical. By engaging with the community through these portals, Sonar developers aim to gather feedback and shape their product roadmap.
