1. Gratic

Gratic operates directly in a browser tab as a vector cartography editor for orienteering and terrain maps.

Overview

Gratic enables cartographers to draw maps directly inside a web browser across Windows, Linux, and macOS without client installation or local binaries. The platform combines national mapping service imports, elevation tiles, and standard sports symbols. Mappers can work simultaneously on the same map from separate machines without exchanging project files, and the software translates external elevation and vector base layers into standard symbols.

How we compared

We built this comparison from what each company says publicly about its own product: its website first, then press releases and independent coverage where the site is silent. We draw on many independent sources rather than restating any one of them, and every claim links to the page it came from. Where a firm clearly does not offer something, the table shows ✗. Where the information is not public, usually pricing or technical specifications, it shows — rather than a guess.

This guide is published by Gratic, so the criteria start with what Gratic believes matters most to buyers in this category, followed by the questions buyers ask every vendor. Gratic's own limitations sit alongside everyone else's.
