Built for real project work
Schedule logic, money, people — and approvals that stick
From the first WBS row to a frozen Review round and board deck, Ganttra keeps cost, resource load, and stakeholder sign-off in one fast workspace.
Cost-loaded schedules & cash flow
Model direct cost, contingency, and markup on every activity. Watch cumulative S-curves, monthly draws, and peak exposure as you edit.
Resource load on the timeline
Toggle weekly assigned hours beneath the Gantt. See who is stacked when, hover for per-resource detail, and track cumulative hours as the schedule moves.
Review rounds & approvals
Freeze a numbered Review round, send a no-login approval link, and collect Approved, Approved with comments, or Changes requested — with email reminders and in-app notifications.
Filters, search & schedule status
Slice critical path, low float, late work, or unassigned tasks with saved filters. Search highlights matches in place, while the status bar keeps project totals and baseline variance in view.
AI-assisted project templates
Turn a project brief into phased WBS starting points. Pro's 600-credit monthly pool is shared with Superintendent so you can use it where it matters most.

FAQ
Answers before you start
Everything you need to know about planning, reviewing, approving, and exporting with Ganttra.
Who is Ganttra built for?
Anyone who needs to plan high-level, cost-loaded schedules quickly — and hand stakeholders something polished without exporting to a dozen other tools.
How is Ganttra different from a traditional Gantt tool?
Every activity carries direct cost, contingency, and markup, so your schedule doubles as a budget and cash-flow forecast. Resource load sits on the same timeline, and as you drag bars, S-curves and weekly hours update in real time.
How do Review rounds and approvals work?
Move a project into Review to freeze a numbered snapshot. Optionally send an approval Review Site — External for client-safe pricing or Internal for full margin detail. Approvers respond with Approved, Approved with comments, or Changes requested; you get a bell notification and email, and can nudge pending requests after 24 hours.
Do my clients need an account to review a plan?
No. Review Sites generate snapshot-backed, no-login links. Share a client-safe External site that folds markup into prices, or an Internal site with full margin and draw detail — and revoke access anytime.
What is included in Free?
Free includes one editable project with up to 100 activities, the full Gantt and CPM engine with critical path, and External Review Sites. It requires no card and does not include AI or the template library.
What does the free trial include?
The 14-day Ganttra Pro trial includes Pro features and the shared monthly AI pool. When it ends, you continue on Free. Choose one project to keep editing; other projects remain viewable and exportable. Existing activities are preserved, including those above 100, but adding activities at the limit requires Core. You can change your Free project once every 7 days.
How do AI credits work?
Ganttra Pro includes 600 credits per UTC month shared by template generation and Superintendent. The Superintendent add-on contributes another 1,500 dedicated monthly credits, higher context, and no daily attempt limit.
Can I import or export my data?
Yes. Import activities via CSV, and export to client or internal PDF, editable PowerPoint, MS Project XML, and CSV so your plans move freely between tools and stakeholders.
