Prove network changes before production
Cassian Gate is a deterministic validation gate that gives you a binary PASS/FAIL result before you touch production.
Install
pipx install cassian-gate
Try it
git clone https://github.com/cassian-gate/cassian-gate.git cd cassian-gate cassian doctor cassian test topologies/first-run-proof-minimal.yaml
What it does
- Validates real network behavior, not just configuration text
- Catches failures before production, not after
- Produces auditable artifacts for every validation run
- Runs in CI/CD pipelines with clean PASS/FAIL exit behavior
What it does not do
Cassian Gate does not auto-fix, does not guess, and does not replace monitoring. It proves changes before deployment.
