OneDesk

OneDesk uniquely combines help desk ticketing with project management, requirements management, and roadmapping tools in a single platform. It allows teams to capture customer feedback and feature requests, convert them into tasks for development, and manage support tickets-all with linked data. It targets product managers and development teams in software companies. It uses a freemium model.

It scores decently for its innovative integration of customer-facing support with internal product development workflows, reducing silos between support, product, and engineering teams.
