Both are open-source personal AI agents that plug into WhatsApp, Telegram, Slack and Discord to act on your messages. People picking a self-hosted Claude-style assistant weigh NanoClaw's tiny sandboxed core against OpenClaw's much larger, longer-running ecosystem.
The verdict
Pick NanoClaw if you want a personal assistant whose entire codebase you can read in minutes and run in a one-person container sandbox
Pick OpenClaw if you need 20+ channels, native desktop and mobile apps, or the freedom to swap in GPT, Gemini or a local model

Side by side
Setup and cost
NanoClaw is MIT-licensed and free; its own quickstart says a scripted install takes 30 to 60 minutes on a Mac or Linux box (Windows needs WSL), and the only ongoing cost is your Claude usage.
OpenClaw is also free and MIT-licensed, but since it runs as an always-on service it is normally deployed on a VPS: real-world self-hosting runs about $5 to $50+ a month in server costs on top of model usage, or roughly $39 to $59 a month for a managed cloud plan.
Security model
NanoClaw: Each NanoClaw conversation runs inside its own isolated Docker (or Apple) container, so the agent cannot touch your raw API keys or the rest of the machine.
OpenClaw relies on application-level permissions and pairing codes rather than OS-level sandboxing; Wikipedia notes critics flag its broad access to email, calendar and messaging, plus exposure to prompt injection and inadequately vetted third-party skills.
Codebase and reach
NanoClaw's core is about 500 lines of TypeScript, readable in roughly 8 minutes, and the repo has about 31,000 stars and 12,800 forks since launching in late January 2026.
OpenClaw's codebase runs past 400,000 lines with 70+ dependencies, but it ships 20+ channel integrations plus native macOS, iOS, Android, Windows and Linux apps, and its repo has grown to roughly 392,000 stars and 82,500 forks.
Model choice
NanoClaw is built specifically on Anthropic's Claude Agent SDK; its setup flow centers on a Claude subscription or API key, with Codex offered as the only other listed option.
OpenClaw treats models as swappable plugins, supporting hosted providers such as Claude and Codex alongside fully local models through Ollama, so you are not locked to one vendor.
Who is behind it
NanoClaw is maintained by NanoCo AI, co-founded by brothers Gavriel and Lazer Cohen, which closed a $12 million seed round led by Valley Capital Partners with Docker, Vercel and monday.com among the backers.
OpenClaw was built solo by Austrian developer Peter Steinberger and, after he joined OpenAI, was handed to the nonprofit OpenClaw Foundation, a 501(c)(3) chaired by Dave Morin, to keep it vendor-neutral.
