Build and manage

Visual Firmware Builder

Draw your firmware as a flowchart and generate readable Zephyr C code.

Web Console

A browser-based console on every device, generated from your app.

AppBlocks Cloud

Monitor, configure, and group your whole fleet, with no SDK.

OTA Updates

Ship new firmware to one device or a whole group, in the field.

Mobile App

Configure devices on site over Bluetooth LE with the LUIS app.

Cloud Workflows

Automate across devices, emails, webhooks, and external APIs.

Protocols and hardware

Modbus

Master or slave, RTU or TCP, with ready-made blocks.

MQTT

Publish and subscribe to any broker, with TLS and QoS 0–2.

Supported hardware

Tibbo devices and Zephyr-supported boards from major vendors.

For PLC and automation engineers

PLC to MQTT and the cloud

Poll PLC registers over Modbus and publish them to MQTT, HTTP, or AppBlocks Cloud.

Remote monitoring and alarms

Watch pumps, tanks, and PLCs at remote sites, with SMS and email alarms over cellular.

Ladder logic to flowcharts

Contacts, coils, timers, and counters, and the blocks that do the same job.

Compare

AppBlocks vs. hand-written Zephyr

Same RTOS, same boards. Far less code to write, debug, and maintain.

AppBlocks vs. Arduino

From a sketch on your desk to a product in the field.

AppBlocks vs. AI-generated firmware

Why verified blocks you control beat code you have to trust.

AppBlocks vs. a PLC

When a connected controller is enough, and when to keep the PLC.
