Statsig vs LLMJury
Statsig is an excellent general experimentation platform. LLMJury is purpose-built for LLM products, where “did it get better?” needs a judge, not just a conversion event. The factual differences:
| Dimension | LLMJury | Statsig |
|---|---|---|
| Built for | LLM products: prompts, models, judge-scored quality | General product experimentation and feature flags |
| Output quality measurement | Built-in LLM-as-judge with custom rubric metrics | Bring your own quality signal |
| Statistical rigor | SRM hard gate + per-metric test routing + BH-FDR correction, recorded on every result | Sequential testing and CUPED on product metrics |
| SDK assignment | Deterministic local hash (Python / TypeScript / Java, cross-verified) | SDKs across many languages |
| Pricing entry | Free plan (50k events/mo), no credit card; Pro $149/mo with LLM-as-judge | Free tier, usage-based paid plans |
