Bitmap venue maps do not scale
Indoor products still rely on bitmap exports of CAD drawings far too often. Structured vector maps are easier to render, edit, validate, and reuse.
Open source building blocks for location software
Open Location Stack
Open Location Stack gives vendors, integrators, and product teams reusable software for hub federation, omlox-compatible integration, command-line operations, and indoor maps across mixed-vendor deployments.
Created by FORMATION
Mission
Open Location Stack focuses on the software teams keep rebuilding between location hardware, hubs, maps, and applications. Real deployments still need the same venue models, connectors, hub adapters, and map tooling project after project. We are building those pieces as open source so vendors and integrators can spend more time on product and delivery work. The project was initiated by FORMATION, where we run production location projects and hit these gaps directly.

Stop rebuilding the same stack
Many location products still rebuild the same hub logic, SDK glue, and map tooling just to get positions on a screen. That wastes engineering time and leaves customers with brittle integrations.
Vendor-specific APIs slow integration work
Location systems only become useful when they connect cleanly to business software and customer workflows. Rewriting adapters for every RTLS vendor is wasted effort.
Closed middleware limits reuse
When hub and integration layers stay proprietary, integrators and product teams inherit more cost, more coupling, and fewer options.
Open source fits this market
Location solutions depend on many hardware and software components across vendors and sites. Rebuilding the same hub, connector, and mapping layers in private silos adds cost and complexity. Open source gives teams something reusable to start from.
Open Location Stack uses the permissive MIT License, so teams can embed, adapt, extend, and white-label the software.
Commercial flexibility
Use the stack in customer projects, packaged offerings, internal tools, or partner-delivered solutions without license friction.
Faster productization
Start from open hub, connector, and mapping components instead of rebuilding the same infrastructure for every deployment.
Shared codebase
An open codebase is easier to inspect, adapt, extend, and integrate across mixed-vendor deployments.
Open Location Stack components
The stack is split into focused projects that can be used together or adopted separately.
Hub and operations
Use the hub for location aggregation and the CLI for repeatable setup, ingest, streaming, and diagnostics.
Open Location Hub
A cloud-capable hub of hubs for filtering and aggregating locations from on-premise omlox hubs, then exposing interoperable APIs to business-facing applications.
Open Location Hub CLI
olh is a command-line client for omlox 2.0-compatible hub implementations. It covers login, resource CRUD, ingest helpers, WebSocket streams, JSON output, and RPC calls.Mapping
Use structured venue data to make location updates usable in products, dashboards, and operational workflows.
Floor Plan Editor
A browser-based editor for structured indoor map data, vector geometry, routing paths, and IMDF-oriented exchange.
Open Location Hub can run on premise, in the cloud, or as part of a horizontally scalable federated deployment. The CLI is designed to work with any omlox 2.0-compatible hub implementation, not only the Open Location Hub runtime.

Reduce lock-in
Keep application teams off vendor-specific hub contracts while preserving local omlox-compatible deployments.
Hybrid tracking
Bring together RTLS, barcode, QR, GPS, and related location systems across sites, zones, and assets.
Federated deployments
Run local hubs on premise, aggregate selected flows in the cloud, and scale horizontally across sites, regions, and tenants.
Indoor mapping that products can use
The mapping side of Open Location Stack focuses on structured indoor map data instead of static floor-plan images. That gives teams a better base for rendering, routing, zoning, and validation.
Shared spatial context
Places, levels, routes, and zones need a shared indoor model before live positions from multiple systems can be interpreted correctly.
Shared site context
A strong map layer helps teams work with mixed tracking systems, site hierarchies, and operational activity in the same model.
Reusable map capabilities
Structured map data makes authoring, validation, rendering, and maintenance more reusable across projects.
Plug in what you need
Open Location Hub supports a wide range of connectors, so existing deployments can participate without a rip-and-replace project.
Existing hubs
Plug in on-premise or cloud hubs such as Corriva Hub, Deephub, or other existing deployments where location data is already flowing.
Location technologies
Bring together barcode and QR-based flows, GNSS, camera-based systems, RFID, BLE, UWB, and other location technologies.
Integrate ERP, MMS, SAP, and more
Send and receive location data and operational events between the hub and ERP, MMS, SAP, and related enterprise systems using reusable connectors.
Grow the connector ecosystem
Location solution providers can contribute connectors, show compatibility, and list support on the Open Location Stack website.
Location technology landscape
Location data comes from many technologies, from software systems and optical workflows to passive tags, outdoor positioning, and precise indoor positioning.
Existing software
ERP, MMS, WMS, MES, SAP, and existing location platforms and hubs.
Optic systems
1D and 2D codes, OCR, and AI-based object recognition.
Unpowered tags and chips
RFID and NFC.
Outdoor positioning
GNSS, telematics, and fleet tracking.
Indoor positioning
UWB, BLE, Wi-Fi RTT, and related indoor positioning systems.
Cradle-to-grave tracking
Most systems only track assets for part of their lifecycle and in limited areas. Cradle-to-grave tracking needs location data from production and logistics through customer use to recycling or decommissioning.
AI for logistics and manufacturing needs context
AI systems in logistics and manufacturing need map context, live location flows, and system events in the same place. Open Location Hub is built to connect those inputs.
Accessible operational context
AI systems need a usable picture of facilities, fleets, flows, and constraints instead of disconnected location feeds.
Integrated workplace visibility
Open Location Hub connects workplace systems, indoor maps, and mixed tracking technologies so automation can work from one shared model.
Foundation for agentic workflows
A shared hub, semantic map structure, and reusable connectors create a better base for orchestration, monitoring, and AI-assisted decisions.
Built for teams across the location stack
Open Location Stack gives integrators, vendors, enterprise teams, and developers reusable software to start from instead of forcing each group to rebuild the same core pieces.
Solution Integrators
Deliver mixed-vendor location solutions faster by reusing shared hub, connector, and mapping components instead of rebuilding the same integration layer for every project.
Location technology vendors
Make your products easier to integrate into real customer environments with interoperable APIs, connectors, and better tooling.
Enterprise users
Reduce deployment and integration risk with a base that fits more naturally into existing enterprise systems and data flows.
Developers
Start with practical middleware and connector frameworks so teams can focus on application logic and delivery.
