# obniz — IoT made simple

> obniz is a Japan-born IoT platform that lets you connect, monitor, and control physical equipment without writing firmware. The platform combines obnizOS-powered devices, the obniz Cloud (API/SDK), and obniz Now (a remote device-maintenance service) 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.
- **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/`.
