Run JANUS locally

1 · Requirement

Docker Desktop (free). That's the only prerequisite.

2 · Install & run (one line)

Run this from inside the folder/repo you want to scan:

curl -fsSL https://januscomp.com/install.sh | sh

Prefer to do it by hand?
docker run --rm -p 8080:8080 -v "$PWD:/workspace:ro" ghcr.io/wildercb/janus:latest

3 · Open & scan

Open http://localhost:8080 → Audit a repo, then either:

• Local path: use /workspace (the folder you launched from), or
• GitHub repo: paste a repo URL — JANUS clones and scans it.

You get the full report: findings, policy mappings, suggested fixes, and auditor artifacts.

4 · Pick a model

• Free & fully local (nothing leaves your machine): run Ollama with a small model — it's the default.
• Your own cloud key: add -e ETHAI_ALLOW_CLOUD_LLM=1 -e OPENAI_API_KEY=sk-... to the docker run.
