NullClaw

Null overhead. Null compromise. 100% Zig. 100% Agnostic. 678 KB binary. ~1 MB RAM. Boots in <2 ms. Runs on anything with a CPU.

The smallest fully autonomous AI assistant infrastructure — a static Zig binary that fits on any $5 board, boots in milliseconds, and requires nothing but libc.

Features

• Impossibly Small: 678 KB static binary — no runtime, no VM, no framework overhead.
• Near-Zero Memory: ~1 MB peak RSS. Runs comfortably on the cheapest ARM SBCs and microcontrollers.
• Instant Startup: <2 ms on Apple Silicon, <8 ms on a 0.8 GHz edge core.
• True Portability: Single self-contained binary across ARM, x86, and RISC-V. Drop it anywhere, it just runs.
• Feature-Complete: 22+ providers, 18 channels, 18+ tools, hybrid vector+FTS5 memory, multi-layer sandbox, tunnels, hardware peripherals, MCP, subagents, streaming, voice — the full stack.

Why nullclaw

• Lean by default: Zig compiles to a tiny static binary. No allocator overhead, no garbage collector, no runtime.
• Secure by design: pairing, strict sandboxing (landlock, firejail, bubblewrap, docker), explicit allowlists, workspace scoping, encrypted secrets.
• Fully swappable: core systems are vtable interfaces (providers, channels, tools, memory, tunnels, peripherals, observers, runtimes).
• No lock-in: OpenAI-compatible provider support + pluggable custom endpoints.
