Open Source Project of the Day (Part 26): ZeroClaw - Full-Rust Autonomous AI Assistant Infrastructure, and Its Relationship to OpenClaw

Introduction "Same vision of 'multi-model + multi-channel + memory + tools,' rewritten in Rust: single binary, a few MB of memory, millisecond startup, and one-click migration from OpenClaw." This is Part 26 of the "Open Source Project of the Day" series. Today we explore ZeroClaw ( GitHub ). OpenClaw (ClawdBot) is the familiar AI assistant gateway: multiple LLMs, Telegram/Discord/Feishu and other multi-channel support, persistent memory, skills and tools — but it's built on Node.js/TypeScript, and the runtime memory and cold-start time aren't great for Raspberry Pi, low-spec VPS, or edge devices. ZeroClaw occupies the same space as OpenClaw — both are "self-hostable, multi-model + multi-channel + memory + tools" autonomous AI assistant infrastructure — but implemented in 100% Rust , targeting zero overhead : single static binary, <5MB memory in common scenarios, <10ms startup , runnable on ~$10 hardware. It preserves identity compatibility with OpenClaw (IDENTITY/SOUL Markdown files)
