Introducing SANDCODE: Your Private AI Coding Companion

We love AI coding assistants. But we didn’t love sending telemetry to third parties, being locked into a single provider, or having no control over the underlying model.

So we built SANDCODE — a fully independent, private AI coding companion that runs on z.ai’s GLM-5.1 model.

Why build it?

We wanted a tool that puts developers first:

What’s inside?

The core is built from the ground up:

The tool system

Everything that makes it great — the REPL, the tool system (Bash, Edit, Read, Write, Grep, Glob), MCP support, hooks, slash commands — all production-ready.

Try it

Terminal window
npm install -g sandcode

Get a z.ai API key at docs.z.ai and start coding.

Welcome to SANDCODE. Let’s forge something.
