phantom-secrets vs satgate

phantom-secrets: Phantom protects sensitive API keys and credentials when working with AI coding agents by replacing real secrets with scoped placeholders. It uses an authenticated local proxy to inject configured authentication values into API requests, preventing agents from directly accessing or exposing actual secret values.; satgate: SatGate acts as an economic firewall for AI agents, governing their API calls by enforcing scoped authority, budgets, and paid-rail context. It prevents unauthorized spending and resource invocation, integrating seamlessly with existing routing gateways and LLM providers.
