The differences that matter most
They differ most on pricing model. Enact publishes USD 279; HelioScope publishes USD 159. They use different pricing models, so those figures do not compare directly.
We do not name a winner. Below are 26 differences drawn from the same sourced dataset that powers both product pages.
Verified against the vendor’s own pages.
These cannot be compared on a single number
Enact is priced per-seat and HelioScope is priced capacity-tiered. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.

Prices are shown exactly as each vendor writes them and are never converted between currencies.
26 differences, ordered by how much they are likely to matter — pricing transparency first, then capabilities the vendor explicitly confirms or denies.

Scroll the table sideways to see both products. The capability column stays in place.
Framed as requirements, not a verdict. Both descriptions come from the same data.
Installers who want one vendor for sales design, permit-grade engineering and post-install monitoring, and who will pay for those as three separate line items. It is not a single unified product: the "end-to-end platform" announced in January 2026 is, as sold on 2026-09-25, three priced modules — one of which still lives on a separate domain under a separate brand, with its own pricing pages that disagree with Enact's.

Full Enact profileFor C&I designers and engineers who need a layout, a bankable-grade production estimate and a sales proposal without leaving one tool. Not for residential one-roof sales work (the same vendor routes that to Aurora) and not for jobs above 30 MW DC — the vendor publishes a hard design-size cap on every tier.

They differ most on pricing model. In total we recorded 26 verified differences and 15 points where they are the same.
Enact is priced per-seat and HelioScope is priced capacity-tiered. These are different pricing models, so a single side-by-side figure would be misleading. Each is shown as its vendor states it.
We do not name a winner. Both are described from the same verified data, and which suits you depends on your requirements — the differences above are the facts; the choice is yours.
