OpenClaw rewritten in Go now runs in 35 MB RAM with a 25 MB binary

Someone reportedly rewrote OpenClaw in Go, cutting the runtime footprint to 35 MB RAM with a 25 MB binary.
The post contrasts that with the original stack, which reportedly needed 1 GB+ RAM and a full Node.js runtime to do less.
What the rewrite supports
- 20+ LLM providers: Anthropic, OpenAI, Gemini, DeepSeek, Groq, xAI, OpenRouter, and others
- 7 messaging channels: Telegram, Discord, Slack, WhatsApp, Feishu, Zalo, Lark
- 3-tier memory: working, episodic, and semantic
- A knowledge vault using hybrid FTS + pgvector
The practical angle is clear: this is an agent/chat orchestration stack that aims to be much lighter and more deployable than the original implementation.
