Reddit blanket blocks all netlify apps, so I am unable to post my app link directly. Click below to go to the app!

Note, this is not mobile friendly and probably never will be. Realistically it needs too much screen space for a mobile app.

TL;DR: I built a browser-based tectonic plate editor for worldbuilders. Draw plates on a 3D globe, simulate spreading/subduction, and build realistic geological histories. Free, no installation.

Hey worldbuilders!

What is GeoChronicler:

A browser-based tectonic plate editor designed for worldbuilders, educators, and geology enthusiasts. Draw plates and continents directly on an interactive 3D globe, simulate plate movement, and build realistic geological histories across deep time—no installation, no learning curve, no GPlates PhD required.

Why I built this:

I'm a software developer who fell down the Worldbuilding Pasta rabbit hole and wanted to build realistic plate tectonics for my own world. GPlates is powerful, but it's industrial-grade geology software. I couldn't find a tool designed specifically for worldbuilders, so I built one.

What makes it different:

• Zero installation - runs completely in your browser
• Worldbuilder-focused - UI designed around creative workflows, not academic research
• 3D interactive globe - draw directly on a rotating planet with intuitive mouse controls
• Snapshot system - automatically saves your world at different time periods (0-1000 Mya), so you can scrub through geological history
• Realistic mechanics - freeze spreading edges to simulate seafloor spreading, split plates along rifts, assign edge types (spreading/subduction/transform)
• Visual hierarchy - plates → continents → cratons/orogens/LIPs organized intuitively
• Export options - save projects as JSON, export maps in multiple projections (Equirectangular, Mollweide, Robinson)
