System-grade sandboxing & zero trust

Code stays local, execution stays bounded. Protected by native OS kernels and auto-review guards.

Guardian Auto-Review

Carefully fine-tuned on security prompts and workspace context, Guardian deeply inspects commands with an LLM before execution to block destructive actions.

Auto review approved

Native OS Sandboxes

Leverages native OS kernel primitives to enforce strict filesystem boundaries without heavy containers.

Seatbelt Bubblewrap Restricted Token

100% Local & Open Source

All sessions and credentials remain 100% on your machine. Fully open source and zero telemetry.

FAQ

Everything you need to know about Caelis, multi-provider workflows, and local runtime safety.

What makes Caelis different from single AI coding assistants?

Caelis lets you combine multiple connected models and ACP Agents in the same session.

How do provider bindings and custom roles work?

You can configure bindings via /subagent. Assign cheap/fast models to Breeze for search & quick edits, reasoning models to Orbit for feature coding, and frontier models to Zenith for review.

Which sign-in and provider connection methods are supported?

Caelis currently supports OAuth for ChatGPT and Grok, plus API keys from multiple Providers. If your usual workflow is not supported yet, Issues and PRs are welcome.

Where is my code and data stored?

Your data stays local. Caelis is open source and transparent, with no data collection or telemetry.
