A new open-source AI agent platform called NanoClaw is positioning itself as a more secure alternative to OpenClaw by running each agent in its own isolated container with strictly limited access to data and tools.
Security by Design
NanoClaw's core principle is container isolation: each agent runs in its own container, preventing cross-agent data access. Unlike OpenClaw, which grants agents broad access to the user's system, NanoClaw agents only see the specific integrations they need.
"Each agent runs in its own container... the agent doesn't see all your WhatsApp data. It only has the specific group and messages it should access," explained creator Gavriel Cohen, a software engineer based in Israel.
A Fraction of the Code
At roughly 4,000 lines of code, NanoClaw is about 1% the size of OpenClaw's 400,000-line codebase. Cohen argues this makes the entire platform auditable and reviewable — an important property for security-sensitive deployments where organizations need to verify exactly what the AI agent can do.
Built on Anthropic's Agent SDK
Rather than reinventing core components, NanoClaw is built on Anthropic's Agent SDK, leveraging existing tools and focusing development effort on the container isolation layer. This approach keeps the codebase small while still providing capable agent functionality.
Origin Story
Cohen began coding NanoClaw at the end of January 2026 after experiencing security concerns with OpenClaw in his marketing agency, where he'd deployed it as a sales management tool. His brother Lazer has since joined the project. AI researcher Andrej Karpathy publicly praised the project, drawing wider attention to the security-first approach.
A Growing Ecosystem
NanoClaw joins a growing ecosystem of OpenClaw alternatives and complements. While OpenClaw offers maximum flexibility and the broadest feature set, projects like NanoClaw demonstrate that the AI agent space is maturing — with different tools optimizing for different priorities like security, simplicity, or enterprise governance.
For users who want the power of OpenClaw with managed infrastructure and security updates, OpenClaw Launch handles deployment, isolation, and maintenance automatically.
