An editable schedule where the built-in Gantt is a picture. Drag a bar to move
it, drag its edge to resize, draw a dependency between two issues, and see the
Critical path through the plan. Baselines record what you promised so Drift
can show what actually happened. There is a per-project chart on the Gantt
tab and a Gantt — all projects view across everything you can see.
Every change is an ordinary issue edit underneath — the same rules, the same history entry, the same notifications — so a drag can never be a way to move a date without leaving a trail.
On your own Redmine
Requirements
- Redmine 6.0 or newer (Rails 7.2, Ruby 3.1 or newer)
- PostgreSQL 14+, or MySQL 8.0+ / MariaDB 10.6+
- No additional gems
Install
cd /path/to/redmine
cp -r redminepro_gantt plugins/
RAILS_ENV=production bundle exec rake redmine:plugins:migrate NAME=redminepro_gantt
# restart Redmine
Standalone behaviour
Identical. No plan gate applies and nothing is capped by tier.
Update and remove
Copy the new directory over the old one, run the migrate command, restart. To remove:
RAILS_ENV=production bundle exec rake redmine:plugins:migrate NAME=redminepro_gantt VERSION=0
rm -rf plugins/redminepro_gantt
# restart Redmine
The built-in Gantt tab comes back exactly as it was. Saved baselines go; every
issue date stays, because those were never this feature's to own.
