GCodex is a free, browser-based G-Code viewer and simulator. No upload required, no signup needed. Features: - 3D & 2D toolpath visualization - Layer-by-layer inspection - Works with CNC machines and 3D printers - Supports Marlin, Klipper, and standard G-Code - Faster and cleaner than NCViewer and gcode.ws Just paste or load your G-Code file and instantly visualize your toolpaths. Perfect for makers, engineers, and hobbyists.
Our team built a low-cost bioprinter and wrote empirically-based G-code software BiosoftX from scratch for hydrogel scaffold generation. To validate that software, we needed a reliable toolpath viewer but every option out there was either paywalled, closed-source, or locked behind vendor ecosystems.
That frustration became GCodex.
Bioprinter vendors charge thousands for proprietary software that does exactly this. We built GCodex free and open because validation tools shouldn't be a luxury reserved for well-funded labs.
It works with everything that runs standard G-code: β 3D Printers: Prusa, Creality, Bambu Lab, Voron, Anycubic, β Bioprinters: Cellink BioX, RegenHU, custom DIY rigs
Drop your file β see your toolpath in 3D/2D instantly. No account needed. Your files never leave your device.
