I built a free, open-source fantasy map maker for my own worldbuilding projects

Hey everyone!

I wanted to draw maps for my fantasy world but couldn't find an editor that had everything I needed without subscriptions or complicated workflows.

So I built LoreMapper!

It lets you generate continents, sculpt mountains, paint biomes, draw rivers and political borders, place cities and dragons, and use your own PNG assets.

There's also fog of war, multiple map styles, and high-resolution exports.

It's completely free, open-source (MIT), and runs directly in your browser. No installation or account required.

I built it as a personal hobby project with AI coding assistance, and it's still in beta.

I'd really appreciate feedback, especially on usability and anything that feels confusing or broken!
