wntrz

Wntrz is a software library and platform designed for indoor spatial data management and navigation. The project provides a unified API for creating, storing, and querying indoor maps, positioning data, and routing across buildings and campuses. It aims to support developers in building apps for wayfinding, asset tracking, and space analytics in complex indoor environments.

The name, inspired by the Polish wnętrze, reflects its focus on interior spaces. Wntrz emphasizes modularity, offline capability, and privacy-conscious data handling, seeking to minimize data dependencies on external services while preserving useful functionality for end users.

Origin and development: Wntrz began as an open-source project in 2018 by a European consortium of universities and technology firms. The first stable release followed in 2019, and since then the project has grown through community contributions and periodic maintainers’ releases. The project is maintained under an open-source license, with a contributor model that welcomes joins from researchers, developers, and system integrators.

Key features include a modular architecture with core modules for map formats, positioning, routing, and data ingestion; support for offline maps and low-bandwidth operation; compatibility with common indoor map standards; and a visualization layer for dashboards and mobile applications. The platform also provides data governance tools and role-based access controls to support privacy and compliance.

Applications span campuses, hospitals, shopping centers, museums, and large office complexes. Users rely on wntrz for wayfinding, asset tracking, and analytics, appreciating its interoperability and lightweight footprint, while occasionally noting limitations in regional data coverage.

Wntrz maintains an active developer community, with regular releases and a growing ecosystem of plugins and integrations.
