Frequently asked

Before you go.

What is Claudium?
A live visualization of your AI coding sessions. Every tool call, every token, every region of the model that fires — rendered as a brain in real time, in your browser. If your team uses Claude Code or another agent runtime, Claudium shows you what it's actually doing.
Does any of my code or prompts leave my machine?
No. Only metadata travels — tool name, region label, token count, and the file path that was touched. We never ingest file contents, prompts, or model outputs. The PII/secret filter on the hub drops anything that looks like a key, token, or password before any other viewer can see it.
Does it work with agents other than Claude Code?
The watcher tails JSONL session logs and the hub accepts inbound events over WebSocket — so any agent runtime that can emit a tool-use record can drive the brain. Claude Code is the out-of-the-box path; bring-your-own-sender is a five-line patch documented in the README.
Is there a free tier?
Yes. The Free plan covers one contributor and 10,000 events per month — enough for an individual developer's daily Claude Code use. No credit card required. Upgrade only when your team or event volume grows.
Can I self-host?
Yes. The whole stack is open source — clone the repo, run npm install, point your CLAUDE_DIR at your projects folder, and you're live on localhost. Bring your own domain via the hub's built-in HTTPS proxy. Enterprise customers get a hardened image with SSO + audit log baked in.
