Redmine’s built-in Gantt is read-only – you can’t drag a task or link a dependency.
Redmine includes a basic Gantt view, but it is read-only – which creates real planning problems for project managers and delivery leads who need to adjust timelines as delivery evolves. Dragging or editing tasks directly on the chart is not possible. Dependency linking between tasks is absent, so cascade delays go undetected until they have already affected downstream work. Reschedules require opening and editing each issue individually, which makes timeline adjustments slow and error-prone.
In plain words
What is the Redmineflux Gantt Chart Plugin?
The Redmineflux Gantt Chart Plugin adds interactive timeline editing directly to Redmine. It lets project managers drag tasks to reschedule, link dependencies, add releases as timeline anchors, and see the full project timeline in a single view – all without leaving the Redmine environment or importing data to an external planning tool.
A full Gantt layer, inside Redmine.
The Gantt Chart Plugin enhances Redmine without replacing it. Every task is draggable. Every dependency is visible as a line on the chart. Releases mark key delivery points — go-live dates, version cuts, client review checkpoints.
Project managers who previously maintained a separate Gantt tool can consolidate timeline planning into Redmine – the same environment where issues are created, tracked, and closed. Redmine, upgraded for operational maturity.
What your team gains
Schedule data that matches your issues, automatically.
Click any shift to see what changes in the product.
01
Interactive rescheduling without editing individual issues.
Drag tasks on the chart to adjust dates, or resize the bar edge to change duration. Changes update immediately — dependency lines make the downstream impact visible so you can act before it becomes a missed deadline. Schedule management takes minutes rather than a full session of individual issue edits.
02
Dependency management that prevents cascade delays.
Link tasks to define finish-to-start and start-to-start relationships. When a linked upstream task moves, the dependency relationship makes the downstream impact immediately visible on the chart – before it becomes a missed deadline.
03
Release bars that anchor delivery checkpoints on the timeline.
Add a release with a name and date range to mark go-live dates, client review points, or version cut-offs. Release bars appear on the timeline alongside task bars — keeping delivery targets visible across the full project lifecycle without a separate planning layer.
04
Real-time schedule visibility for all stakeholders.
Schedule changes made by one project manager are visible to every team member and stakeholder with access to the project. There is no lag between a planning decision and its reflection in the timeline view.
05
All projects in one cross-project Gantt timeline.
The Global Flux Gantt is accessible from the top navigation and brings every project’s timeline into one view. Paginated project rows, lazy issue loading, cross-project dependency lines, and IssueQuery-based filters — all without switching between individual project Gantts.

Frequently asked
Frequently Asked Questions
The questions teams actually ask before adopting the Gantt Chart Plugin. If yours isn't here, check pricing or contact support.
Can I view tasks from multiple projects in one Gantt?
Yes. The Global Flux Gantt is accessible from the top navigation and displays all projects in a single cross-project timeline view. Projects appear as paginated rows with lazy issue loading. Cross-project dependencies are visible on the same chart, and IssueQuery-based filters let you narrow the view without switching between individual project Gantts.
Does the plugin support baseline comparisons?
Yes. Set a baseline from your original schedule and compare it against the current plan at any point during the project. Baseline comparison shows schedule drift visually on the chart, making it straightforward to identify which tasks have shifted and by how much since the project started.
Can multiple users edit the Gantt chart simultaneously?
Yes. Multiple project managers or team leads can work on the Gantt chart at the same time. Changes made by one user are reflected in real time for others viewing the same project. Conflict handling follows Redmine’s standard issue locking behaviour for concurrent edits.
Which Redmine versions are supported?
The Redmineflux Gantt Chart Plugin is tested and maintained against all Redmine versions. Compatibility is verified with each plugin update.
How much does it cost?
$499 one-time for self-hosted – 1 year of support included. Support renewal after 1 year 30% of plugin price.
