OpenClaw-class agents on ESP32 (and the IDE that makes it possible)
Hi HN, I’m the creator of pycoClaw. I wanted to run OpenClaw-class, platform-agnostic, autonomous agents on MicroPython hardware, but standard tools couldn't handle the scale of the task. pycoClaw is the result, which bridges the gap between high-level AI reasoning and bare-metal execution.

In plain words
pycoClaw is a framework for running autonomous AI agents on microcontroller hardware like the ESP32. It consists of a PFC Agent that uses an LLM to generate and execute MicroPython scripts locally, ScriptoStudio, a web-based IDE with debugging capabilities, and ScriptoHub, a repository for pre-built agent skills. Designed for developers who need to deploy autonomous agents on resource-constrained devices, the system allows tasks to run independently after initial LLM-assisted setup, reducing ongoing cloud dependencies.

Hi HN, I’m the creator of pycoClaw. I wanted to run OpenClaw-class, platform-agnostic, autonomous agents on MicroPython hardware, but standard tools couldn't handle the scale of the task. pycoClaw is the result, which bridges the gap between high-level AI reasoning and bare-metal execution. The Stack: - PFC Agent (~26k LOC): A full-featured agent that uses an LLM to 'self-program' its own local MicroPython scripts. Once a task is solved, it runs locally without requiring the LLM. - ScriptoStudio IDE: A PWA https://scriptostudio.com designed for the iteration speed required by autonomous agents. Since it’s a PWA, it brings a full dev environment (including a real single-step debugger) to any platform, including iPadOS. - ScriptoHub ( https://scriptohub.ai ): A repository for "Skills" and extensions. Since the agent can generate and execute code, I built a curated hub with automated malware checking to ensure the community can safely share and deploy hardware logic. - IANA Protocol: To make the IDE fast and reliable, I registered a new WebSocket subprotocol (registry: https://www.iana.org/assignments/websocket/websocket.xhtml ). It’s designed for high-frequency state sync and you can read the spec here: https://jetpax.github.io/webrepl/webrepl_binary_protocol_rfc... - Custom C Extensions: ~17,900 lines custom modules for MicroPython memory/ fast-path speed optimization Stats: 10k LOC platform, 26k LOC PFC agent, and ~18k LOC of custom C extensions to optimize MicroPython’s memory and fast-path execution on the ESP32. Quick Start: You can flash the runtime to an ESP32S3 or P4 in one click via WebSerial at https://pycoclaw.com. Note that all flashing and serial communication happens entirely client-side in your browser. I'd love to hear your thoughts on the 'self-programming' model or the system architecture!

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
