We make hardware easy.
LabWired lets you build and test embedded systems without waiting on hardware. Lay out a board and its parts in the browser, write and compile the firmware, and run it on a register-accurate simulation of the chip. The simulation is deterministic, so the same firmware behaves the same way every time — a result is a real pass or fail, not a guess from reading the code.

Makers. Design a board in the Playground, drop in parts, wire it up, and watch the firmware run in your browser. Free to try, nothing to buy first.
Teams. Gate CI and real hardware on register-accurate behaviour, catch firmware bugs before a board is on the desk, and drive the whole thing from your own agent or ours, on-prem if you need it.
Both run on the same simulation underneath. When you're ready, the same binary runs on a real board over WebUSB-JTAG.
| Design | Lay out boards, parts, and wiring in the browser Playground. |
| Build | Write firmware in Studio or VS Code and compile it hosted (PlatformIO, Zephyr). |
| Run and verify | Run on the deterministic simulator and check behaviour against what you specified. |
| CI and hardware | Gate merges on a simulation run, then run the same binary on a real board. |
| Agents | An MCP interface, ready-made skills, and a preconfigured agent. |
Silicon we model: STM32 · ESP32 (Xtensa and RISC-V) · nRF52 / nRF54 · RP2040 · Cortex-M.
People use the Playground and the Studio IDE, plus a VS Code extension. Agents drive the same tools over MCP: connect Claude Code or Codex, or use the LabWired agent, which comes preconfigured and can run on a local model with no internet.
| Repo | What it is |
|---|---|
| agent | The LabWired agent — opencode preconfigured for firmware, runs on a local model offline |
| firmware-test | Run LabWired simulation tests in GitHub Actions — no hardware, no toolchain |
| firmware-ci-starter | Template repo — firmware, a test script, and CI wired up on your first push |
| skills | Agent skills for firmware work, starting with firmware-verification |
| labwired-cra-evidence | CRA-style secure-boot / signed-OTA evidence pack, regenerated in CI on a virtual nRF52840 |
