Feature-by-feature comparison
How Grafient and Langfuse compare across the features that matter most for AI cost tracking.
Why teams choose Grafient
Key advantages when your primary goal is tracking AI costs.
Zero code changes
Langfuse requires instrumenting every LLM call in your application with their SDK. Grafient connects to provider billing APIs directly - no SDK, no decorators, no wrapper functions. Your code stays untouched.
Billing-accurate costs
Grafient reads actual invoiced costs from provider billing APIs, not estimates derived from token counting. This means your cost data matches your invoice exactly - including cached tokens, batch discounts, and tier-specific pricing.
No maintenance burden
Grafient is a fully managed SaaS. Langfuse self-hosting requires provisioning infrastructure, managing database migrations, and handling upgrades. Even Langfuse Cloud requires keeping your SDK integration up to date.
Purpose-built cost features
Forecasting with confidence bands, spike detection, model downgrade suggestions, cache efficiency analysis, and budget alerts with webhook notifications. These cost-specific features do not exist in Langfuse.

The verdict
An honest assessment of when to use each tool.
Langfuse is an excellent tool if you need deep LLM tracing, prompt management, and evaluation workflows - especially if you value open-source and self-hosting. But if your primary need is cost tracking - knowing exactly how much you spend on AI across all providers - Grafient gives you that in 2 minutes with zero code changes and billing-API-accurate data. No SDK, no instrumentation, no infrastructure to maintain.
