Best Self Hosted Alternatives to TeamGantt

Leantime is an open-source project management system designed to combine strategy, planning and execution into a single workspace. It emphasizes personal dashboards and cognitive-friendly UX, with features aimed at helping teams and individuals align tasks to goals and milestones.

Key Features

• Personal "My Work" dashboard with time-blocking, notes and cross-project task visibility
• Multiple task views: Kanban, table, list and calendar; unlimited subtasks and dependencies
• Milestones and timeline (Gantt) views with program-level planning and milestone grouping
• Strategy and goal management (vision, focus areas, project-goal linking, blueprints)
• Built-in wikis/docs for project knowledge and idea/validation boards (Lean Canvas, SWOT)
• Time tracking, timesheets and basic reports/dashboards for progress and billing
• Plugin system and JSON-RPC API for extensions, plus integrations with chat platforms
• Official Docker image and a development docker-compose environment; configurable via .env
• AI-assisted features (task prioritization, task breakdowns, status reports) available in paid/hosted tiers

Use Cases

• Small to mid-size teams that need a combined strategy-to-execution workspace with goals and milestones
• Consultants or agencies who want client-facing project dashboards, idea boards and documentation in one place
• Organizations that require self-hosting, data ownership and extensibility via plugins or the API

Limitations and Considerations

• Official system requirements target PHP 8.2+ and MySQL/MariaDB; PostgreSQL is not listed as supported
• Some advanced AI features and managed hosting capabilities are available only in the commercial/hosted offering or via paid plugins
• Requires several PHP extensions (bcmath, mbstring, pdo_mysql, gd, openssl, etc.) and attention to webserver configuration when self-hosting

Leantime provides a full open-source core focused on linking strategy and execution while offering paid hosting and plugin options for additional features. It is suitable for teams that want a self-hosted, extensible PM platform with an emphasis on accessible UX and goal alignment.
