AppBlocks for Zephyr
Zephyr is powerful — but complex. AppBlocks lets you design your firmware logic visually and compile it straight to a Zephyr project, for hundreds of supported boards.
No deep RTOS knowledge required. Just draw your flow.
What is Zephyr?
Zephyr is an open-source, scalable real-time operating system backed by the Linux Foundation. It supports hundreds of boards from major silicon vendors, including Nordic, STMicroelectronics, NXP, Espressif, and many others.
Zephyr is fast, lean, and designed for resource-constrained embedded devices, but its configuration system, build toolchain, and device tree model have a steep learning curve that can slow down even experienced firmware developers.
Zephyr is Powerful.
And Terrifying.
CMake, Kconfig, device tree overlays, west manifests, RTOS primitives — getting a Zephyr project off the ground takes time even before you write a single line of application code.
Most developers spend more time wrestling with the toolchain and boilerplate code than writing the actual application.
AppBlocks Tames the Complexity
With AppBlocks, you draw your application logic as a flowchart. AppBlocks handles all Zephyr complexities — threads, queues, GPIO bindings, timers — and generates clean, working Zephyr firmware.
You focus on what your device does. AppBlocks handles how Zephyr does it.
Why AppBlocks?
Targets All Zephyr-Compatible Boards
From Nordic nRF chips to STM32 to ESP32 — if Zephyr supports it, AppBlocks works with it.
Visual Firmware Design
Draw flowcharts in the browser instead of writing RTOS code. No complex installs, boilerplate code, threads, or other complexities.
Faster Time to Working Firmware
AppBlocks cuts days or even weeks off your project. Your iteration speed accelerates, too.
Produces
Clean Code
AppBlocks generates readable, maintainable Zephyr C code you can inspect and extend.
AppBlocks in the Age of AI
AI can write firmware code from a prompt — but raw AI output comes with serious reliability concerns. Will you bet your (customer's) farm on it?
Hundreds of Supported Boards
Nordic, STM32, ESP32, and other major brands — if Zephyr supports them, AppBlocks can target them.
Cross-Pollination: TiOS, Zephyr, and TPS
AppBlocks on Zephyr isn't some from-scratch experiment. It inherits decades of lessons from developing Tibbo OS (TiOS). It also gives back, supercharging our TPS platform in return.

Zephyr Makes TPS Better, Too
Looking for a Complete Industrial Solution?
AppBlocks was built alongside the Tibbo Project System (TPS) — a modular platform for industrial automation and IoT. If you need a deployment-ready device, not just a dev board, TPS has you covered.
