Photonic simulation at GPU speed.
LeapField Workbench is a desktop 3D FDTD electromagnetic solver for photonics. Design, simulate, and analyze on your own machine — free on your CPU — and send the same simulation to data-center GPUs when you need the throughput.
Product
Serious physics, without the cluster.
LeapField pairs a rigorously validated finite-difference time-domain solver with a workflow that runs where you are: on a laptop for design iteration, on cloud GPUs for production sweeps.
Validated physics
Results are benchmarked head-to-head against leading commercial FDTD solvers and published device papers, with convergence studies behind every claim — accuracy you can audit, not just quote.
Cost-per-result GPU
One click sends a simulation to data-center AMD GPUs and streams the result back. Runs are metered by compute — with a transparent estimate before you commit — not by seat licenses or idle clusters.
A complete workflow
A visual Workbench for structures, sources, and monitors; GDS import; built-in Python notebooks; and a scriptable SDK — from layout to transmission spectrum in one tool.

Requirements
What you need.
| macOS | macOS 14 or later on Apple Silicon (M1 or newer). |
|---|---|

| Local runs | Free during the beta. Simulations executed locally — inputs and results — stay on your machine. |
FAQ
Common questions.
What does LeapField cost?
During the beta, local CPU simulation is free. Cloud GPU runs are metered by compute, and Workbench shows a transparent cost estimate before every run. Invitations may include introductory cloud credit to get you started.
Which platforms are supported?
macOS 14+ on Apple Silicon and Windows 11 x64. Intel Macs, Windows 10, Windows on ARM, and Linux are not supported by the beta installers yet.
How do invitations work?
Registration requires a one-time invitation code. Use the request form (or email beta@leapfield.app) with a line about what you're building; accepted testers receive a personal download link and invitation code.
Where does my data go?
Local simulations run entirely on your machine, and their inputs and results stay there. Only account sign-in — and the cloud runs you explicitly start — cross the network.
