Powerproject — formerly Asta Powerproject, now sold by Eleco — earned its reputation on real jobsites: decades of construction-first CPM, progress-line workflows, and professional planners who swear by it, especially in the UK and Europe. Ganttry doesn't out-rank that pedigree; it changes the economics. The same CPM fundamentals, live in a browser for the whole crew, at $20/user/month — instead of a $1,320-a-year Windows seat (US price via Catalyst USA, Eleco's distributor).
Ganttry's annual plan vs the Powerproject single-user subscription via Catalyst USA, Eleco's US distributor. Even paying monthly ($240/yr), the gap is about 5.5×.
Ganttry runs on Mac, Windows or the iPad in the truck — nothing to install. Powerproject is a Windows desktop app; sharing schedules live means adding Eleco server or cloud products.
Ganttry crews update progress from phones on the normal seat — installable app, My Tasks, calendar. Powerproject's Site Progress Mobile is a separate paid add-on, priced per job.
In the US you buy Powerproject through Catalyst USA, Eleco's official distributor, and billing is annual everywhere official — there is no monthly option. As of July 2026 the published numbers look like this; concurrent SaaS and the Vision portfolio layer are quote-only.
One named user, one year at a time. UK buyers pay £1,470/yr on Eleco's own store — annual billing only, auto-renews, 60-day cancellation notice.
A floating license the whole office can share — one user at a time. A genuine option Ganttry doesn't offer; larger concurrent and SaaS deals are quote-only.
The 4D BIM edition costs materially more (roughly $2,345+ US). Site Progress Mobile field capture runs about $205 per job per year through resellers — reseller figures, not official list prices.
Compared against the Powerproject single-user subscription — the seat you'd actually buy. Green means it's included at the tool's quoted per-seat price.
A Powerproject seat is $1,320 a year before the BIM edition or the per-job field add-on. A Ganttry seat is $200 — and the foreman's seat costs the same as the planner's, so the whole crew lives in the live schedule instead of a printout. That's how a ten-person job ends up more than $11,000 apart, every year.
Ganttry annual plan ($200/user/yr) vs Powerproject single-user subscription ($1,320/yr via Catalyst USA). Powerproject's $2,200/yr concurrent license can stretch across rotating users — one at a time per license.
Powerproject speaks MS Project formats natively — export your schedule as MS Project XML, drop it into Ganttry, and the dependencies, calendars and structure come with it. (Coming from spreadsheets instead? CSV/Excel import has mapping presets.) Monthly updates re-import in place without touching your notes and colors. And when someone upstream insists on Powerproject or Project, export MS Project XML back — they can open it directly.
