agentsight alternatives
Curated alternatives to agentsight — and why you'd switch.
numbat
Perplexity's endpoint sensor for AI agents: hooks, OTLP logs and on-disk session artifacts normalized into one CEL-matched event model, with opt-in pre-action blocking and offline forensics.
Why switchBoth sensors for what a coding agent did on the box. Numbat cooperates with the harness — hooks, OTLP logs, session artifacts; AgentSight is harness-agnostic, tracing eBPF and TLS so it works on any binary, including ones with no hooks.
Full comparison →failproofai
Observability plus policy enforcement for agent harnesses: records every run across 12 harnesses (Claude Code, Codex, Cursor, Hermes…) and blocks dangerous tool calls with 39 built-in policies.
Why switchBoth watch what a coding agent does on the machine. AgentSight observes from the kernel with eBPF — any binary, no hooks, no blocking; Failproof AI hooks the harness and enforces policies before a tool call runs. Observe-everything vs enforce-what-you-hook.
Full comparison →LangSmith
Trace, test and monitor LLM apps in production.
Why switchAgentSight's own framing: LangSmith is right when you own the application code and want traces, prompts and evals; AgentSight is for the layer below — a closed agent CLI whose real effects (processes, files, network) only show up at the system boundary.
Full comparison →Adrian
Runtime security for AI agents: watches actions AND reasoning traces to catch prompt injection, tool poisoning and out-of-remit behavior — blocking before the action lands. SDKs + Claude Code plugin.
Why switchBoth look for agents misbehaving at runtime. Adrian inspects actions and reasoning for injection and tool poisoning; AgentSight audits the actual system effects — which files changed, which services got requests — from outside the agent.
