How to use Fact0?
Developers can integrate Fact0 into their backend using the Python SDK to start logging agent actions, tool permissions, and human overrides. Once integrated, teams can monitor real-time activity feeds via the dashboard, visualize execution steps via a DAG, generate signed compliance evidence packs, and ask questions about logs in plain English using the built-in Fact0 Spotlight AI assistant.
How to use Arcjet?
Choose an Arcjet SDK or agent framework integration, install it in your application, and configure rules in code or remote policies. Call protect() for HTTP routes or guard() inside an agent tool handler, workflow step, or other action path. Supply relevant inputs such as the actor, action, and typed arguments, then use the returned decision to allow, block, redact, or hold the action for review. Teams can begin in dry-run mode and review recorded decisions before enabling enforcement.
