Every single time
From line plots to 3D surfaces — interactive visualization built right into the notebook.
Plot rendered: Signal vs Noise
Complete numerical computing—no bloat, no complexity.
Multi-cell editor with syntax highlighting and autocomplete.
Math, linear algebra, sparse matrices, polynomials, and plotting.
Line plots, scatter, histograms, 3D surfaces, and more.
WebAssembly powered. Your data stays local unless you opt into cloud storage.
Breakpoints, step through code, inspect variables.
Save locally or use cloud storage across devices.
Running on your own device usually means a performance trade-off. It doesn't here: Equana uses WebAssembly to deliver computational performance that rivals desktop applications—no server round-trips required.
