Powerproject — sold today by Eleco as Asta Powerproject — 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 Windows license, sold as a subscription at $1,320 per license (Catalyst USA, a US reseller Eleco lists); Eleco's own store bills it yearly.
Ganttry's annual plan vs the Powerproject single-user subscription from Catalyst USA, a US reseller Eleco lists, whose page names no term. Eleco's own store bills that subscription yearly; at that term, 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 (a Mac needs its SaaS tier); sharing schedules live means adding Eleco server or cloud products.
Ganttry crews update progress from phones on the normal license — installable app, My tasks, calendar. Powerproject's field app, Asta Siteprogress, is a separate paid service, charged by active project.
In the US you can buy Powerproject from Catalyst USA, one of the resellers Eleco lists. Eleco's own store bills annually, with no monthly option. As of September 2026 the published numbers look like this; SaaS, Asta Enterprise and the Asta Vision portfolio layer are priced on request.
One user per license; Catalyst's page names no term. UK buyers pay £1,530/yr (VAT included) on Eleco's own store — billed annually, 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 priced on request.
Asta 4D, the 4D BIM version, ran about $2,345 or more a year in the US, and Asta Siteprogress field capture about $205 per project per year, through resellers as of July 2026 — reseller figures, not official list prices.
Compared against the Powerproject single-user subscription — the license you'd actually buy. Green means it's included at the tool's quoted per-license price.
A Powerproject license is $1,320 (Catalyst USA) before the 4D module or the per-project field app, and Eleco's own store bills that subscription yearly. A Ganttry license is $200 a year — and the foreman's license costs the same as the planner's, so the whole crew lives in the live project instead of a printout. At Eleco's yearly term, that's how a ten-person project ends up more than $11,000 apart, every year.
Ganttry annual plan ($200/user/yr) vs Powerproject single-user subscription ($1,320 per license, Catalyst USA), counted yearly: Catalyst's page names no term, and Eleco's own store bills the subscription annually. Powerproject's $2,200 concurrent subscription 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.
