OpenTask review
A focused open-source task app for projects, nested tasks, and due-date views.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenTask is a free, open-source task manager delivered as a responsive progressive web app. It is aimed at users who want a minimal web tool for organizing plans and goals into projects and to-dos. Tasks can be grouped within projects, broken into nested actionable tasks, and assigned due dates. The product is presented as a community learning project rather than a business-focused primary task-management app, making it a better fit for straightforward personal organization than for users seeking a broad productivity suite.
Its structure centers on project-based organization and time-focused task views. Users can arrange work into projects, split larger to-dos into smaller actionable tasks, and review items scheduled for today or already overdue. The responsive progressive web app format supports access through the web while adapting to different screen sizes. This focused feature set should suit users who prefer a clear hierarchy of projects, tasks, and subtasks without a crowded interface.
OpenTask's main trade-off is its narrow scope. The published positioning does not verify reminders, recurring tasks, integrations, or offline access, so users who depend on automated notifications, repeating workflows, connected services, or offline task management should choose an alternative. It also carries a clear product-context limitation: the vendor presents it as a community learning project, not as a primary task-management product for business use. Choose OpenTask for a free, open-source web task manager with projects and due-date views; choose elsewhere for broader platform coverage or more advanced task automation.
