Read the Garak pageGarak vs Inspect AI
Our take
Pick Garak if you're on a app / security team who will run Community-style scans at $0 and already have a model API key. Pick Inspect AI if you're on a eval / safety team who will run Inspect locally at $0 (you bring model API keys) — not Promptfoo first unless they want a YAML CI red-team harness. Skip Garak if you're on a team that want a YAML eval matrix + hosted dashboard (Promptfoo) or a research log viewer
