# obniz — physical infrastructure for the AI era

> obniz is physical infrastructure for the AI era: a Japan-born IoT platform that lets software and AI agents read from and control physical equipment without writing firmware. Power on an obnizOS device and it is immediately callable from code, from REST/GraphQL/WebSocket APIs, and from an MCP server — so you can build the whole application on obniz Now, or wire the devices straight into your own system. obniz is made of three products — obnizOS devices (cloud-connected devices running a dedicated OS, with setup and cloud-link features built in, usable via MCP / APIs / code), obniz Cloud (the service that manages devices as a fleet: multi-device bi-directional control from anywhere, device authentication, MCP / API access, and an online dev environment for beginners), and obniz Now (a system for building applications on obniz Cloud: data storage, user management and invitations, end-user screens). Our solutions business combines these three to solve real-world problems: facility maintenance, temperature monitoring, remote PLC control, and turning your own products into smart, connected ones — all at low cost and short lead time. Operated by obniz Inc. since 2018, with 40,000+ devices deployed across 300+ companies. ISO/IEC 27001 (ISMS) certified.

## Key characteristics

- **Firmwareless**: obnizOS is pre-flashed on supported MCUs, so you don't write firmware. Develop entirely in cloud-side JavaScript or Lua.
- **Free to start**: obniz Cloud's Lite plan is ¥0/month with official devices — connection management, per-device authentication, TLS, and OTA updates included. Paid plans begin only when you need the obniz Now application layer or business features.
- **Multi-protocol**: Wi-Fi, Ethernet, LTE-M, NB-IoT, Bluetooth, Zigbee/Thread. Pick what fits the site.
- **AI integration**: An MCP (Model Context Protocol) server lets Claude, Cursor, and other agents access obniz devices and obniz Now data directly (Developer Preview).
- **Security**: TLS 1.2 with elliptic-curve crypto, per-token authorization, kernel-virus-resistant MCU architecture. ISO/IEC 27001 certified.
- **Track record**: In production since 2018. 40,000+ devices, 300+ companies.
- **Japanese support**: Built and supported in Japan, with full Japanese documentation. Japanese site at `/ja/`.
