PileCalc
DeepFND alternative

Looking for a DeepFND alternative? Keep the one-tool workflow, cut the invoice.

PileCalc is a browser-native DeepFND alternative: the same one-tool philosophy — lateral, axial, groups, shafts, footings — validated against LPILE and RSPile, free to try and $39.99/month. No modules, no Windows, no quote call.

No install, any OS

DeepFND 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

≈ $2,250/yr (single piles) to $9,650/yr (full, with groups, FEM & cap design). PileCalc is free to start and $39.99/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 DeepFND

  • Browser-native at no extra charge — DeepFND's cloud access is a +$1,200/yr module
  • Transparent public pricing: free tier and $39.99/month vs a $2,250–$9,650/yr modular subscription
  • Groups and helical piles included, not modular edition upgrades
  • Validation numbers published openly against LPILE and RSPile

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.
