Plan first.
Create issues later.
Most Gantt tools assume the work already exists. Sketch the timeline, dependencies, and dates first — push to Jira only when the plan is solid.

Plan first.
Create issues later.
Preplanning Gantt (PreGantt) lets teams build Gantt-style plans, dependencies, baselines, and calendars in Jira — then transfer work into your project only when the plan is ready.
Why PreGantt
Plan first.
Keep your
backlog clean
Explore “what if” scenarios, move dates, and rebuild dependencies — without flooding your project with draft issues.
Hourly mode —
plan the whole day
Days are the default. Hours are when it gets real. Enable Hourly mode to place multiple tasks on one day, zoom down to hours, and pin start and end times — so your plan reflects the actual schedule, not a blurry block on Tuesday.
Virtual people
& statuses
You don't need real assignees or Jira workflows to start planning — invent roles, departments, and statuses as you go. They live in the plan until you're ready to transfer.
Templates —
skip the busywork
Stop re-entering the same fields for every typical task. Create personal, plan, or project templates, share them with the team, and add new rows in seconds.
Native to Jira —
not another tab
A Forge app inside your Cloud site — PreGantt project tab or global Apps menu, synced with Jira work items.
Calendars that respect
working days
Customize your work week and holidays per plan or project — hide weekends, add days off, and keep durations realistic.
Flexible UI —
your workflow, your rules
Highly flexible UI customization for your comfort and efficiency — show status columns, colour bars by hierarchy, highlight the critical path, and reorder the task panel to match how you actually plan.
Your plan becomes
part of the project
Transfer approved rows into real Jira issues and keep linked work in sync with the plan.
Classic Gantt —
covered too
Of course — all the essentials you'd expect from a proper Gantt chart are built in. Drag bars, link tasks, save snapshots, and spot what drives your deadline.
