Tech Highlights
Fast & Lightweight
Because no one likes waiting, ObjectBox is 10X faster than any alternative and comes with an incredebly lightweight footprint.
Vector Search
Very first on-device offline vector search powering on-device AI; cloud optional. Powerful in combination with our Data Sync.
Sustainable
Due to its efficiency, ObjectBox reduces resource-use (CPU, memory, energy…) and therefore CO2, time, and money waste
Offline first
For the low-latency “always-on” experience. Develop applications that work on- and offline, unburdened by the need for a constant Internet connection.
Data Control
Self-host, deploy locally, and run on-premise – ensure data sovereignty, compliance, and seamless performance even in low-connectivity environments.
Data Sync
Never miss a beat. Our bi-directional, offline-first Data Sync keeps data flowing seamlessly across devices on the edge and from edge to cloud – 100% cloud optional.

“ObjectBox is a great candidate to store events and handle them later, amongst many other interesting features.”
ObjectBox
ObjectBox is an on-device Database with Vector Search and out-of-the-box Data Sync, designed for resource-efficiency on mobile, IoT, and other embedded devices, like e.g. ECUs, robots, machines. It also excells on servers and cloud systems. The lightweight database uses minimal computing resources like e.g. CPU, memory, energy (battery) and is therefore superfast, sustainable, and cost-effective across environments and workloads. At the same time, it is transactionally-safe (ACID complaint) and reliably persists and synchronizes data under all kinds of challenging conditions, e.g. flaky networks, offline scenarios, on-premise, occassionally connected devices, etc. Easy to integrate and use, ObjectBox is developed by developers for developers, taking on the hard and unfavorable parts, so that developers can focus on the value-add features while we do the heavy lifting in the background.
