PileCalc
RSPile alternative

Looking for an RSPile alternative? Same modern workflow, no install.

PileCalc is a browser-native RSPile alternative: lateral, axial and groups, validated term-by-term against the RSPile theory manuals, with every curve exposed and transparent pricing. Free to try, $29/month for Pro — on any OS.

No install, any OS

RSPile is Windows-only. PileCalc runs in any browser on macOS, Windows, Linux or a Chromebook — nothing to download, no dongle, no license server.

Transparent, lower price

≈ $1,099 / year (personal lease). PileCalc is free to start and $29/month for Pro — priced in the open, with no four-figure quote-by-email license.

Validated and visible

Checked term-by-term against LPILE and RSPile, with the numbers published — and every input, assumption and curve shown inline so you can audit the result.

What you keep when you switch from RSPile

  • Browser-native — nothing to install, works on any OS
  • Raw p-y / t-z / q-w curves surfaced and exportable by default
  • Built-in explanations on every input (a common RSPile documentation request)
  • Shareable cloud projects and transparent, public pricing

The numbers, published

PileCalc's engine is checked term-by-term against the reference codes. A representative sample of the benchmarks — every intermediate value is visible in the app so you can reproduce them yourself.
