I've been running OpenClaw as my personal AI assistant for a few months — it handles my Discord, Slack, WhatsApp, runs scheduled tasks, controls my browser. It's basically my second brain.
Then PicoClaw dropped in February 2026, and I had a spare NanoKVM sitting on my desk. So I set it up on a $10 RISC-V board with 128MB of RAM, just to see if it could actually work.
Here's what I learned.
The quick version
OpenClaw is the full-featured TypeScript assistant that runs your digital life. It needs >1GB RAM and a real machine to run on.
PicoClaw is the Go rewrite that fits in a RISC-V chip. It uses 20MB of RAM, boots in under a second, and does everything PicoClaw needs to do — minus the stuff that requires a full desktop.
One sentence each:
- PicoClaw: run AI agents on hardware you forgot you owned
- OpenClaw: run AI agents that do everything you wish your computer could do automatically
Where they came from
OpenClaw started as "Clawdbot" — Peter Steinberger (the PSPDFKit founder) built it as a weekend project to relay WhatsApp messages to Claude. Then on January 9th 2026, Anthropic blocked third-party OAuth tokens, and suddenly everyone needed an alternative. Stars exploded from 2K to 219K in 3 months.
It got renamed twice — Anthropic's lawyers objected to "Clawdbot" sounding too close to "Claude," so it went Clawdbot → Moltbot → OpenClaw. In February, Steinberger joined OpenAI and handed the project to an independent foundation.
PicoClaw came from Sipeed, a Chinese hardware company that makes those tiny RISC-V boards. Their observation was simple: OpenClaw needs more than 1GB of RAM. It's not running on a $10 board. So they built a Go reimplementation that would.
By February 2026:
- OpenClaw: 219K stars, 774 contributors, 50 releases
- PicoClaw: 18.3K stars, 74 contributors, 3 releases — with most of the code written by the AI agent itself (95% agent-generated, they claim)
The actual difference in practice
Memory footprint:
My OpenClaw setup idles at around 1.2GB on my Mac. PicoClaw on the NanoKVM? About 20MB — they originally targeted <10MB but recent features pushed it up a bit.
Startup time is where it really shows. OpenClaw takes ~5 seconds on my M2 Mac. On a 0.8GHz board, that's 500+ seconds. PicoClaw starts in under a second on that same board.
What you can actually do with each:
PicoClaw covers the essentials: Slack, Telegram, Discord, plus the Chinese messengers (DingTalk, WeCom, QQ, LINE). It can search the web, read/write files, run shell commands, and schedule tasks. For edge deployment, that's enough.
OpenClaw covers all of that plus WhatsApp, iMessage, Signal, Teams, Google Chat, Matrix — basically the entire Western messaging stack. Then it adds browser automation (full Chromium CDP), a canvas for visual workspaces, voice wake, camera access, iOS/Android/macOS companion apps, and multi-agent coordination. It's a different beast.
The LLM provider situation:
Both work with the usual suspects: OpenAI, Anthropic, Gemini, Groq, DeepSeek, Ollama, OpenRouter, Cerebras. PicoClaw adds GitHub Copilot support (via gRPC, though without tools). OpenClaw adds NVIDIA and Volcengine.
I use Groq free tier on PicoClaw (it's free, fast, good enough for simple tasks) and Anthropic Claude on OpenClaw for the heavy lifting.
The skills/customization angle
Both use SKILL.md files for extending capabilities. The formats are almost identical — which makes sense since PicoClaw was explicitly inspired by the same patterns.
OpenClaw has ClawHub (clawhub.com), an actual marketplace where people share skills. PicoClaw doesn't have a marketplace yet — you're writing your own or adapting from OpenClaw's ecosystem.
OpenClaw also has Lobster, a typed workflow pipeline engine for complex automation. PicoClaw doesn't have this yet.
When I actually use which
PicoClaw — I use it for:
- Always-on monitoring tasks that don't need heavy compute (checking price drops, RSS feeds, simple notifications)
- Running on old Android phones and the NanoKVM
- Situations where I need something booting in 1 second on cheap hardware
OpenClaw — Everything else. Specifically:
- WhatsApp and iMessage integration (PicoClaw can't do these)
- Browser automation (clicking things in Chrome, scraping, login flows)
- Canvas for visual output
- Multi-agent workflows where one agent spawns subagents
- Anything requiring the iOS app for camera or voice
The DNA they share
What's interesting is how similar the architecture is under the hood:
Both have:
Workspace/ agent working directory
AGENT.md behavior/personality
SOUL.md tone and style
skills/ modular capabilities
cron/ scheduled tasks
sessions/ conversation history
Gateway mode always-on daemon
Agent mode one-shot CLI
Heartbeat periodic background tasks
Sandbox security boundary
This isn't accidental. PicoClaw's README literally says "inspired by the same principles." They're the same idea at different resource points on the spectrum:
$10 RISC-V ─────── Raspberry Pi ─────── Desktop/Server

PicoClaw both work OpenClaw
(only option) (pick by features) (full power)
Bottom line
If you want to run AI agents on cheap hardware, edge devices, or anywhere Node.js is too heavy — PicoClaw is genuinely impressive. The 20MB footprint is real. The fast boot is real.
If you want an AI assistant that handles WhatsApp, controls your browser, talks to your phone, and coordinates multiple agents in parallel — OpenClaw is what you actually want.
Most people running homelab setups end up using both: OpenClaw as the main brain on a real machine, PicoClaw on Raspberry Pis and old phones for lightweight monitoring tasks.
They're not competing — they solve different parts of the same problem.
