Best alternatives to AgentSight in 2026
Most tools that monitor AI agents require the agent to cooperate: you add an SDK, wrap API calls, or integrate a proxy. That doesn't work if the agent is a closed-source CLI like Claude Code or Gemini CLI, and it also means the agent's own instrumentation could be blind to something it wasn't told to report. AgentSight sidesteps this entirely by watching from outside the process, at the operating system level. AgentSight uses eBPF — a Linux kernel technology for safe, low-overhead system observation — to intercept TLS-encrypted LLM traffic and correlate it with kernel-level events like file access and network activity, without requiring any SDK, proxy, or code changes to the agent itself. It works with Claude Code, Codex, Gemini CLI, OpenCode, OpenClaw, or effectively any command-line agent. It's built to detect prompt injection attacks, catch resource-wasting reasoning loops, and reveal coordination bottlenecks in multi-agent systems, all while adding under 3% performance overhead. It ships with a web dashboard showing session timelines, process trees, and a 'semantic flamegraph' for reasoning traces, is grounded in peer-reviewed research (published at a 2026 ML-for-systems workshop), and is free and open-source under MIT.
