# Langfuse vs EvalGate: tracing, release gates, or both?

Langfuse is a strong fit for teams seeking open-source or self-hosted LLM observability. EvalGate focuses on reviewed behavior contracts, approved baselines and regression decisions in CI. They can complement one another rather than requiring a replacement.

## Choose Langfuse when
Self-hosted tracing, prompt observability and open-source workflows.

## Choose EvalGate when
Local or CI regression gates that protect reviewed outcomes.

## Differentiation
- EvalGate: Code-reviewed baseline and explicit regression result linked to a change.
- Langfuse: Open-source and self-hostable telemetry workflows.

## Pricing
Langfuse offers a free cloud tier, paid options and self-hosting; compare your actual usage units.

## Limitations
EvalGate does not replace Langfuse's self-hosted observability stack.

## Migration
Retain Langfuse traces and instrumented applications. Use real incidents to create reviewed EvalGate tests; keep both if they serve different needs.
