About React IoT

React IoT designs ESP32 hardware and firmware, then builds the platforms and tools to operate it. On the hardware side that means fieldbus-to-MQTT gateways — 1-Wire, CAN, RS485, LIN and TTL — pre-flashed, certified, and ready to publish to your broker over Ethernet or Wi-Fi, plus custom hardware design, compliance and volume manufacturing.

The tools around the hardware

We build and use our own tooling: ESP32 Workbench flashes, debugs and monitors boards from the browser with no install, and TestBench wraps a device under test in programmable I/O, power, bus traffic and measurement so automated and agent-driven tests run on real silicon in CI. Both are tools we built and use ourselves.

Levirge is our sister product — an agentic platform for operating the systems behind your firewalls and guiding coding agents. It is a separate product; see levirge.com.

We publish the tools we rely on as open source — see what we maintain.

Where we are

React IoT is based in Australia. Book 30 minutes with an engineer — not a sales rep — at hello@reactiot.com.au.

About this site

The site itself is markdown-first: every page is a single .md file, rendered to HTML for humans and served as clean Markdown to agents — a deliberate showcase of LLM-friendly content delivery.
