天枢 (Tiānshū) — the first star of the Big Dipper. The pole star points; it doesn't shout.
Tianshu is an open-source AI agent platform with three opinions baked into its core architecture:
- 🧠 Plan + Workers — A main agent decomposes goals; named workers (代码 / 设计 / 投研 / 内容...) execute in isolated sandboxes. Inspired by China's mythical craftsmen (鲁班, 女娲, 羲和...).
- 📡 Multi-channel — Chat with your agent on web, IM, and physical devices. One brain, many surfaces.
- 🔒 Multi-tenant by design — Every user gets isolated execution and memory. No shared state, no leakage. Self-host with confidence.
Most agent platforms today are:
- Closed source / vendor-locked
- Single-tenant or with porous isolation
- Web-only, with no story for IM or hardware
- Built on assumptions that don't survive contact with real users
Tianshu is what I want to use myself — and what I think a serious open-source alternative needs to look like.
Building from zero, with deliberate care. No code in this org yet — that's intentional. I'll commit the first repo when it's worth showing.
I post weekly devlogs covering architecture decisions, what broke, and what got cut.

The code isn't public yet, but feedback shapes it.

⭐ Tianshu — the first star. It points the way, quietly.
