Why rewrite in Go?

Node.js served OpenClaw well. Go unlocks a different class of performance and simplicity for always-on personal infrastructure.

Single Binary
Compile to a ~12MB executable. Deploy to any server without installing Node.js, npm, or any runtime.
🧠
Markdown Memory
Two-tier: daily .md logs + longterm.md facts. Human-readable, git-trackable, editable in vim.
🔌
gRPC Sidecar Skills
Write skills in Python, Rust, Node, or Go. GoClaw auto-discovers them and routes tool calls seamlessly.
📡
Multi-Channel
One agent, many inboxes. Telegram, Discord, WhatsApp, Slack — all share the same memory and context.
🌐
Browser Control
Chromedp/CDP integration. Navigate, click, fill forms, screenshot, and scrape from natural language.
🤖
Agentic Loop
Full tool-call loop up to N iterations. Works with Anthropic, OpenAI, Gemini, and local Ollama.

Architecture

One control plane

A WebSocket gateway at the center, all components connected via an in-process event bus — no unnecessary microservices.

⚡
Goroutine-native
Each channel runs in its own goroutine. The bus dispatches to subscribers concurrently.
🔒
No shared state
Components talk only via the bus or explicit calls — never shared variables.
📁
Filesystem-first
Plain Markdown files. No migration headaches and trivially easy to edit by hand.
🌐
Language-agnostic
The gRPC contract is the only interface. Skills can be in any language.

What the community is saying about GoClaw.

"

Replaced my whole janky Node.js + pm2 + docker compose setup with a single 12MB binary. Running on a $4 VPS, idle at 18MB RAM. Absolutely unreal.

The gRPC sidecar system is genius. I wrote my Notion skill in Python in 20 minutes. GoClaw just picked it up and the LLM started using it immediately.

Memory system is so underrated. Just plain Markdown files I can edit in vim. No database migrations, no vector embeddings. Just files. Perfect.
