NullClaw

NullClaw is an autonomous AI assistant runtime written in Zig and compiled to a tiny static binary (678 KB, ~1 MB RAM, millisecond startup per its README) aimed at cheap ARM, x86 and RISC-V boards. It claims 50+ providers, 19 channels, 35+ tools, multiple memory engines, MCP, subagents and voice, with core systems exposed as swappable vtable interfaces. Security features include pairing, sandboxing via landlock, firejail, bubblewrap or Docker, allowlists, workspace scoping and encrypted secrets. It sits within a wider Null ecosystem (NullHub UI, nullboiler orchestration, nullwatch observability).
