CartoLynx – Interactive RPG & World Map Editor
CartoLynx is a free, browser-based interactive map editor built for Tabletop RPG (TTRPG) Game Masters, fantasy authors, and worldbuilders. It lets you turn static map images (PNG, JPEG, WebP, SVG) into connected, interactive world atlases featuring customizable markers, atmospheric hover tooltips, and hierarchical sub-map navigation—allowing players or readers to travel seamlessly from a continent map down into a kingdom, city street, or multi-level dungeon.
Built around the "World as a File" principle, CartoLynx processes everything 100% locally inside your browser without accounts, cloud databases, or subscriptions. When you save or export your project, CartoLynx bundles all map images, markers, and lore into a single, self-contained HTML file. This standalone file can be shared via chat, email, or USB drive, opened in any web browser completely offline, and re-imported into the CartoLynx editor at any time for further editing.
CartoLynx is designed for creators seeking a fast, lightweight, and privacy-first alternative to complex cloud-hosted worldbuilding wikis, campaign database platforms, or markdown map plugins. If you want interactive cartography and nested maps without database management, markdown configuration, or recurring paywalls, CartoLynx gives you a portable atlas that stays permanently yours.
