worklenz

Worklenz is a free, open-source project management platform for teams and agencies, bringing projects, tasks, resource planning, and client collaboration into one workspace. Tasks can be viewed as a list, a Kanban board, or a Gantt chart, and time is logged directly against them. Alongside delivery it tracks budgets, costs, and team utilization, so project health and profitability stay visible. Worklenz can be self-hosted under AGPL-3.0 or used as a managed cloud service that has a free plan.
