Le Gantt - 2026 Pricing, Features, Reviews & Alternatives

Le Gantt transforms Trello boards and Basecamp projects into interactive Gantt chart timelines. The product operates as two distinct extensions that integrate within existing Trello and Basecamp interfaces to provide visual project planning functionality. It supports project managers, team leaders, and organizations that rely on Trello or Basecamp for task management but seek enhanced timeline visualization, dependency mapping, and scheduling capabilities. Le Gantt maintains bidirectional synchronization with the underlying project management platforms, ensuring modifications made in the Gantt chart view are reflected within Trello boards or Basecamp projects and vice versa.

For Trello users the Power Up integrates directly in each board and preserves all project data within the Trello environment without external databases or separate account creation. It enables task dependencies to be created with drag and drop interactions and allows dates to be scheduled and adjusted directly on the timeline. Basic functionality is provided at no cost and optional advanced features are available for specialized requirements.

For Basecamp users the extension delivers auto scheduling that adjusts dependent task dates when predecessor tasks change. It includes critical path analysis to identify task sequences that drive overall project duration and baseline comparison tools for tracking schedule variance. The extension also supports milestone marking to highlight key dates and visual scheduling through draggable timeline bars for setting start dates and deadlines. Progress tracking is available with task completion visualization to convey project status.

Le Gantt operates as a layer on top of existing Trello and Basecamp installations rather than as a standalone platform and ensures that all project data remains stored within the chosen project management system. The Trello extension uses the native Trello API accessed during installation to maintain a completely Trello native operation. The Basecamp extension leverages the Basecamp API to read to-do items and write date modifications back to the original project, maintaining bidirectional synchronization. Neither extension requires migration of existing project data or the creation of duplicate databases because the Gantt visualization is generated dynamically from the current state of boards or projects. The Basecamp extension offers a fourteen day trial period without requiring credit card details for initial access and the Trello extension provides free baseline functionality with optional paid upgrades for additional features.
