SimplexGen Studio

The native desktop mesh editor. Same simplification, repair, remesh and paint tools as the web app, running locally on your own files with no upload step and no generation credits. Everything on this page is optional — the web app stays fully featured.

Install

The installer downloads a signed-checksum archive, verifies it against SHA256SUMS, and places simplexgen in ~/.local/bin (or %LOCALAPPDATA%\Programs\SimplexGen on Windows). Set SIMPLEXGEN_PREFIX to install elsewhere, or SIMPLEXGEN_VERSION to pin a release. Prefer to read before you run? install.sh · install.ps1

SimplexGen Mojo engine

A separate, headless build of the geometry core — Voronoi relaxation, QEM decimation and mesh repair — for batch pipelines and servers. No window, no GPU required. Linux x86_64 only; the bundle ships its own Modular runtime libraries.

curl -fsSL https://simplexgen.com/install-mojo.sh | sh
simplexgen-mojo --batch

Installs to ~/.local/libexec/simplexgen-mojo with a launcher symlinked into ~/.local/bin. Script: install-mojo.sh

Which one do I want?

Studio (Zig)
Interactive editor with a 3D viewport. macOS, Linux, Windows. Use this unless you specifically want a pipeline tool.
Mojo engine
Headless geometry core for scripted or server-side batches. Linux only.
Web app
No install, plus text-to-image and image-to-3D generation. The desktop builds do local mesh work only — generation stays on the web app.

Requirements

macOS
macOS 12 or newer, Apple Silicon or Intel.
Linux
glibc 2.31+, X11 with an OpenGL 3.3 driver.
Windows
Windows 10 or newer, 64-bit, OpenGL 3.3.
Disk
Studio ~20 MB installed; the Mojo bundle is larger because it carries its runtime.
