Ganttry vs Primavera P6

Primavera P6 is the contract-grade CPM standard — when a DOT or owner mandates a scheduling tool, it's usually this one. Ganttry doesn't pretend to replace that mandate. It opens the XER files P6 users send, logic and calendars intact, and gives the rest of the team a live browser schedule at $20/user/month instead of a quote-only Windows desktop seat that runs roughly $4,300 in year one per reseller quotes — Oracle publishes no list price.

YEAR-ONE PRICE PER SEAT

$200/yr vs ≈$4,300

Ganttry's annual plan vs a P6 Professional perpetual license plus first-year support, per reseller quotes — Oracle publishes no list price. About a 20× gap.

THE SCHEDULE LIVES

In a browser vs in an XER

Ganttry is one live schedule with presence, conflict-safe saves and history. P6 Professional is a Windows desktop app; sharing a schedule means exporting and emailing XER files.

YOUR XER FILES

Import, intact

Ganttry imports XER with logic and calendars preserved, and re-imports monthly updates in place. It does not export XER — if the contract requires P6-native files, you still keep a P6 seat.

What Primavera P6 actually costs

There is no price on Oracle's website — P6 Professional is sold by quote through Oracle sales and authorized resellers. The figures below are what resellers publish and quote as of July 2026; treat them as the going rate, not an Oracle list price.

P6 Professional license

≈$3,500–3,880 per user, perpetual

Reseller list runs about $3,880; typical quotes land around $3,492–3,520. Quote-only — no published price, no card checkout, no self-serve trial.

THE YEAR-ONE MATH

License + annual support

≈$4,300 first year, per seat

Oracle support runs about 22% of the license (~$774–854 the first year) and renews annually with uplift. Technically optional — but it's what gets you upgrades and support.

Oracle Primavera Cloud (OPC)

≈$130 /user/mo, 5-user annual packs

Oracle's newer cloud scheduler, also quote-only via resellers. A different product from P6 Professional — this page compares against the desktop P6 most contractors are actually asked for.

Figures via authorized Oracle resellers, July 2026 — Oracle publishes no list prices for the products priced above (P6 Professional license, support, OPC). The P6 family also includes P6 EPPM, the web/enterprise edition, sold through the same sales channels. Every P6 Professional seat carries the full CPM engine; there are no feature tiers.

Feature for feature

Compared against P6 Professional, the desktop edition. On core CPM mechanics the two agree — the split is collaboration, access and price on one side, enterprise depth on the other.

Perpetual license vs subscription, honestly

A perpetual license sounds cheaper eventually — but with ~22% annual support renewing on top of a ≈$3,880 license, P6 never crosses under Ganttry's line. Five years out, one supported P6 seat (≈$7,500 before support uplift) still costs about what thirty-five years of a Ganttry seat would. And that's one seat: P6 pricing is why only the scheduler gets P6, while Ganttry's $20 is why the whole crew gets Ganttry.

P6 figures are reseller quotes (≈$4,300 year one, ≈$800/yr support renewals thereafter, before uplift) — estimates, since Oracle publishes no list price. Ganttry is the published $200/user/yr annual plan.

Where Primavera P6 still wins

•It's the contract-grade standard. Many DOTs, agencies and owners require P6 schedules by name. If your spec says P6, that argument is over — you need a P6 seat for the deliverable.

•Enterprise multi-project database. A single database of every project, enterprise structures and global data — depth Ganttry's jobs dashboard doesn't attempt.

•Automatic resource leveling and global change. P6 levels across projects and mass-edits with global change rules; Ganttry shows crew histograms and leaves leveling decisions to you.

•Claims and forensic scheduling. Delay analysts, claims consultants and schedule reviewers live in P6 — its acceptance in disputes is earned and real.

•XER is the lingua franca. The whole heavy-construction world exchanges XER files, and P6 writes them natively. Ganttry reads them but doesn't write them.

Where Ganttry pulls ahead

✓One live schedule, whole crew. Presence, live selections, conflict-safe saves and per-author history with rollback — versus one user per desktop and XER files in email threads.

✓The field is included. Crews status their own tasks from their phones via an installable app — same $20 seat, no separate Oracle product to license.

✓About 20× cheaper in year one. $200/user/yr, published on the website, versus roughly $4,300 per quoted seat — a price that decides who gets access at all.

✓Trial today, not a sales cycle. 14-day self-serve trial and card checkout — no reseller call, no quote, no procurement round-trip.

✓DCMA health checks built in. The 13-point audit with editable thresholds and a submittal-ready PDF — not built into P6 Professional.

✓Any OS, nothing to install. Mac, Windows, iPad — a browser tab, not a Windows install with database drivers.

Your XERs already open here

Drop the XER your scheduler or GC sends into Ganttry and the logic, lags and calendars come through intact. Monthly updates re-import in place. To be plain about the reverse trip: Ganttry exports PDF, Excel, CSV and MS Project XML — not XER. If the owner mandates P6-native files, keep one P6 seat for the submittal; Ganttry is where the rest of the team works between submittals.
