An open-source map tool for real-time collaborative exploration and annotation.
Mapus is an open-source web application that provides interactive maps with real-time collaboration features. It allows users to draw, add markers, measure distances, and explore places together synchronously, solving the problem of asynchronous map planning in tools like Google MyMaps.
Teams, friends, or organizations needing to collaboratively plan trips, events, or spatial projects, such as travel groups, real estate analysts, event coordinators, or disaster response teams.
Developers choose Mapus for its self-hostable, real-time collaborative mapping without vendor lock-in, offering a free, open-source alternative to proprietary tools with a simple, focused feature set.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Enables synchronous collaboration with live cursors and annotations, allowing users to plan trips or projects together without delays, as highlighted in the features list.
With an MIT License, it can be deployed on any domain or commercialized, offering freedom from vendor lock-in and control over data, as noted in the installation section.
Prioritizes simplicity and real-time interactivity over complex features, making it easy to use for collaborative mapping without unnecessary bloat, per the project philosophy.
Allows exporting map annotations as GeoJSON for use in other GIS tools, enhancing data portability and external analysis, as mentioned in the features.
Self-hosting requires creating a Firebase project, configuring databases and authentication, which adds significant setup overhead compared to plug-and-play solutions, as detailed in the installation steps.
Relies on free OSM APIs that restrict autocomplete and show only up to 10 nearby places at a time, hindering detailed exploration without switching to paid alternatives like Google Places, as admitted in the feature ideas.
The README openly lacks routing, text annotations, and built-in sharing controls, requiring custom development or plugins for full functionality, which limits out-of-the-box utility.
