Four domains

It can defend; it can attack.
It can be the spear; it can be the shield.
Only your intent decides.

Vehicle & Aircraft Control

Flight controllers, FPV, UGVs, robotic arms — the firmware layer.

Example: ESP32-S3 + ELRS receiver

IoT Device Tooling

Smart switches, sensors, JLCPCB boards, Xianyu-built hardware.

Example: ESP32-C3 + custom PCB

Network Security

Router firmware, zero-trust mTLS, encrypted tunnels, SPIFFE edge nodes.

Example: ESP32-S3 + SPIFFE workload

Edge AI

Camera vision, tinyML, local inference, LLM integration.

Example: ESP32-S3 + camera + ONNX

Workflow

Forge the gear you reach for first.
Sharpen your agent —
and yourself.

01 · Model the device

Three wizards — Sidecar for zero-trust mTLS, Bastion for standalone gateways, UGV for vehicle control. Fill in BOM, sensors, and protocol stack once; save as reusable profiles.

Every profile can be edited or replayed independently

02 · Compile in the cloud

Multiple ESP-IDF versions (v5.x / v6.x) coexist; pre-warmed caches let the remote agent handle the compile. Logs stream back over WebRTC. Your machine never installs ESP-IDF, Python, or CMake.

Failure is data too — failed builds can be signed into a triple

03 · Hand off the firmware

When the build is green, flash directly over Web Serial from the browser. For offline targets, download .bin and use esptool or espflash locally.

Billed per build, not per minute

Where it sits

An agent's agent.
A lieutenant's lieutenant.
Every line gets a reply; every thing finds its place.
Division of labor. Collaboration.

ESPCTL MCP — development

Agent writes the code. Browser tunes compile flags. Cloud compiles.

espctl + deposit — flash / verify / record

Big models do the exploratory work; small models do the deterministic verification. Picks up the cloud-built artifact → flashes the device → runs physical verification → signs the build into a requirement + code + verification triple in ~/maker-assets/. Triples never leave your disk.
