Simple Gantt vs Structure.Gantt
Structure.Gantt is a capable Gantt chart add-on for Jira — but it's not standalone. It requires a separate Structure PPM license, which means two subscriptions, a complex setup process, and a significant monthly cost. If you're looking for a Structure.Gantt alternative that works out of the box without prerequisites, here's how Simple Gantt compares.
TL;DR
- ✓ Price: Simple Gantt is free to get started. Structure.Gantt requires two licenses — for 100 users, expect ~$473/month combined. No free tier.
- ✓ Prerequisites: Simple Gantt is standalone — install and go. Structure.Gantt requires Structure PPM to be installed and configured first.
- ✓ Security: Simple Gantt is Forge-native (runs on Atlassian infrastructure). Structure.Gantt is Connect-based (external data processing).
- ✓ Unique features: Simple Gantt includes a project health dashboard, change history/audit trail, and 15+ quality validation rules that Structure.Gantt doesn't have.

One app, not two subscriptions
Structure.Gantt doesn't work on its own. It's an add-on to Structure PPM, which is itself a paid Jira app. That means two Marketplace subscriptions, two sets of permissions to manage, and two vendor relationships to maintain.
For a team of 100 users, the combined cost runs to approximately $473/month. There's no free tier for either product, so you're committing to a significant expense before you've even seen if it fits your workflow.
Simple Gantt is a standalone app. Install it from the Atlassian Marketplace and you have a working Gantt chart in minutes. No prerequisites, no secondary licenses, and free to get started.
Project health and quality validation built in
Structure.Gantt is strong on the fundamentals — dependencies, critical path, baselines. To be fair, it does those well. But it's primarily a scheduling tool.
Simple Gantt goes further with a project health dashboard that gives you a risk score (0-100), workload distribution across assignees, phase status tracking, and recent activity — all in one view. You don't just see the timeline; you see whether your project is healthy.
The quality validation engine runs 15+ checks automatically: missing dates, date conflicts, circular dependencies, orphaned tasks, and overdue items. Each issue links directly to the task that needs attention. It's the kind of proactive monitoring that prevents problems instead of just displaying them.
Full change history for accountability
Neither Structure PPM nor Structure.Gantt provides a dedicated change history for your Gantt schedule. When dates move or dependencies change, there's no easy way to trace what happened.
Simple Gantt logs every modification with before/after values, the user who made the change, and a timestamp. Filter by task, user, change type, or date range. This is particularly valuable for teams in regulated industries or anyone who needs a clear audit trail for project decisions.
Forge-native: your data stays on Atlassian infrastructure
Structure.Gantt and Structure PPM are both Connect apps, meaning your Jira data is sent to and processed on the vendor's external servers. For many organizations — especially those with data residency requirements — this is a significant concern.
Simple Gantt is built on Forge, Atlassian's hosted compute platform. Your data is processed and stored entirely within Atlassian's cloud infrastructure. It automatically inherits your Atlassian data residency settings — if your data must stay in the EU, Australia, or US, it does.
With two Connect apps (Structure + Structure.Gantt), you're trusting two external systems with your project data. With Simple Gantt, there are zero external servers involved.
