The best alternatives for AI agent monitoring

LangSmith, Helicone, LangFuse and ClawPulse — compared on price, setup and what each actually captures in production.

Run ClawPulse alongside your current tool in 2 minutes.

The 3 main alternatives

Each solves a different layer: code-side LLM tracing, request-edge proxy, or system-side infrastructure agent.

Prompt-level tracing for LangChain-first teams

Price: $39/mo (Plus, 1 seat)
Setup: SDK integration in code
Best for: Deep prompt/response inspection inside LangChain apps
Limitation: SDK instrumentation required · LangChain ecosystem first · $39/mo per seat

LLM-proxy that logs every prompt & response

Price: $20/mo (Pro) + usage
Setup: Swap API base URL + auth
Best for: Teams comfortable swapping LLM API base URL for rich per-request logs
Limitation: Proxy adds 50-200 ms latency · no infra metrics · usage-based overages

Open-source LLM tracing SDK (self-hostable)

Price: Free OSS · $59/mo hosted
Setup: Install SDK + self-host server
Best for: Engineering teams that want to self-host and instrument their LLM calls
Limitation: Self-hosting ops overhead · no system-level uptime · code changes required
