AgentMeter Vs Langfuse
A factual comparison between open-source LLM observability and AI agent cost infrastructure.
Choose Langfuse when the priority is LLM tracing, evaluations, prompt iteration, and observability. Choose AgentMeter when the priority is cost attribution by customer, non-LLM usage, runtime cost controls, and customer billing.

Different Center Of Gravity
Langfuse is widely used for LLM observability workflows. AgentMeter is designed for the business side of production agents: cost, margin, control, and billing.
Comparison
The practical choice depends on whether your next problem is debugging agent behavior or controlling agent economics.
| Workflow | AgentMeter | Langfuse |
|---|---|---|
| LLM traces and observability | Basic trace and cost views | Core workflow |
| Non-LLM cost pricing | Builder-configured metrics | Requires custom work |
| Per-customer margin | Core workflow | Requires custom work |
| Pre-call cost reactions | Rules in SDK path | Not the primary focus |
| Usage billing | Connected to billing surface | Requires separate system |
How They Can Coexist
A team can send detailed traces to an observability stack while using AgentMeter as the source of customer cost, budget enforcement, and billing records.
Is AgentMeter open core?
Yes. The SDKs and core backend are MIT licensed, with enterprise modules separated under an ELv2 license.
Should I migrate traces into AgentMeter?
Only if the trace is needed for cost or billing. Keep deep debugging in the observability tool that already serves that workflow.
