obniz is a single platform built from six tightly integrated layers.
Hardware, OS, connectivity, cloud, and applications — all the way up to use-case solutions like temperature management, leak detection, and PLC remote control. Every layer follows the same design philosophy. Here we walk through each one and how the SDKs fit together.
Why obniz
Hardware, firmware, cloud, security — domains that take years to build in-house.
Our patented Firmwareless Technology lets you add or change features without ever touching the device firmware. On-site logic can be updated from the cloud as many times as you like, even after deployment — no need to recall devices, and no downtime.
TLS 1.2 encrypted communication, per-device public-key authentication, OTA updates, and connection monitoring are all built into the platform. obniz runs everything under ISO/IEC 27001 certification — there is nothing for you to provision or operate.
Since development began in 2014, more than 40,000 cumulative devices have been deployed across 300+ companies. Temperature management, facility monitoring, PLC integration — the platform has been battle-tested for over eight years in real operations.
LTE / LTE-M, NB-IoT, Wi-Fi, and Ethernet are all unified on a single platform. Pick the best option for the site — outdoor, mobile, closed network, or office — while the upper layers and your code stay exactly the same.
Lua Plugin lets you push decision, aggregation, and compression logic onto the device itself. With AI generating Lua code dynamically based on what is happening on-site and pushing it live, only the data you actually need gets sent — cutting traffic by tens to hundreds of times.

SDK & Integrations
The SDK is what bridges the application layer to the cloud.
Quick Start
Load obniz.js, supply an OBNIZ_ID and access_token, and you are connected. The same code runs in the browser and in Node.js. The access_token enforces authorization, blocking unauthorized connections.
obniz.js reference
const obniz = new Obniz("OBNIZ_ID", {
access_token: "token_xxx"
});
obniz.onconnect = async () => {
const voltage = await obniz.ad0.getWait();
};JavaScript SDK
Connect to obniz devices in just a few lines from the browser or Node.js.
Multi-tenant App SDK
Built for SaaS managing fleets of devices.
Development Toolkit
When self-hosting obnizOS devices, obniz-dock spins up your own server with the same developer experience as the App SDK.
CLI
Drive obnizOS from the command line.
On-Device Logic
Run lightweight logic directly on the device.
AI Integration
A Model Context Protocol server that lets AI agents like Claude operate obniz devices directly.
Resources
SaaS off the shelf, a custom app on the SDK, or hardware embedded into your product line — we will help you put together the configuration that fits.
