A browser your agents can drive.
Tabs, logins and recordings in the same window, so agents check what they build.
- Agent login
- Screen recording
- Network capture
Context from your company.
Spaces issues, docs, decisions and goals, read and written from the chat.
Before you decide.
When is Antigravity the better choice?
If you want Google's agent in an editor built around it, Antigravity is made for that.
Can I use Google models in Nucleus?
Yes. Nucleus has models from every major lab, picked per chat.
Does my code leave my machine?
Your repo and worktrees stay on your Mac. Cloud runs upload the work only when you start one.
What does it cost?
Free to start, and one subscription covers both apps. Agents on your own subscriptions bill to those, not to your credits.
Is it Mac only?
Yes, for now. Nucleus and Spaces are built for Apple silicon Macs, and there are no Windows or Linux builds yet.
