Quantum chemistry, right in your browser.

THE GAUSSIAN 16 ALTERNATIVE

Upload a GAMESS, Gaussian or XYZ molecule and run energies, geometry, IR · Raman · UV-Vis · NMR spectra, NLO and thermochemistry — all in one consolidated report. No installation, no Linux, no license server.

10-day free trial · no credit card · works on any PC (and your phone)

Everything Gaussian does — without the friction

🌐

Nothing to install

Runs entirely in the browser. Any Windows PC, Mac — even a phone. No compiling, no Linux, no hardware license dongle.

GAMESS .inp/.gamin, Gaussian .gjf/.com, XYZ. Method, basis, charge and geometry are detected automatically.

🧩

9 modules, one report

Energy, geometry, electronic structure & NLO, vibrational (IR/Raman), UV-Vis & NMR, thermochemistry & BSSE, multi-method & CASSCF, visualization — one branded PDF.

🧪

Interactive & visual

Rotate the 3D structure live, view HOMO/LUMO and density cubes, read IR, Raman and UV-Vis stick spectra.

Runs on the server

Long jobs run in the background. Close the tab and come back — every result is waiting for you in History.
