agentlens vs preflight

agentlens: AgentLens is an open-source observability tool designed for AI agents, capturing every LLM call, tool invocation, and decision. It stands out with a tamper-evident audit trail, cryptographically verifying events to ensure compliance and data integrity.; preflight: Preflight provides observability for AI coding assistants, tracking their actions, costs, and efficiency as they work. It offers a local-first dashboard for real-time insights and optional integration with New Relic for team rollups and advanced analytics.
