Eppo
Warehouse-native experimentation platform that runs statistical analysis directly in your data warehouse (Snowflake, BigQuery, Redshift, Databricks). Provides feature flags with assignment logging, metric definitions, and rigorous frequentist/Bayesian analysis.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTPS enforced. SDK key is read-only — compromise only allows reading flag configurations. SOC 2 Type II. Warehouse data stays in customer's own cloud account.
⚡ Reliability
Best When
You have a data warehouse, value statistical rigor, and want experiment results fully owned in your own infrastructure with no data leaving your environment.
Avoid When
You don't have a data warehouse or want a self-contained experimentation platform without warehouse dependency.
Use Cases
- • A/B test agent model versions or prompt strategies with statistically rigorous analysis computed in your existing data warehouse
- • Use Eppo SDKs to assign users to experiment variants with server-side feature flags for agent capability rollouts
- • Log agent behavior events to your warehouse and use Eppo's metric definitions to measure experiment impact on business outcomes
- • Progressive rollout of new agent tools or configurations using Eppo's traffic allocation controls with automatic guardrail metric monitoring
- • Power users or enterprise teams that want full data ownership of experiment assignments and results in their own warehouse
Not For
- • Teams that don't have a data warehouse — Eppo requires Snowflake, BigQuery, Redshift, or Databricks as the analytics backend
- • Simple feature flag use cases — Eppo is optimized for experimentation, not simple flag management
- • Very small teams (< 5 engineers) — setup complexity requires a data engineering resource
Interface
Authentication
SDK key for flag assignment (read-only). API key for management operations. SDK key is environment-specific (production vs. staging).
Pricing
No free tier. Pricing is not publicly disclosed for enterprise plans. Eppo targets companies with $10M+ ARR or established data teams.
Agent Metadata
Known Gotchas
- ⚠ Eppo requires assignment events to be logged to your data warehouse — if your agent's logging pipeline fails, experiment assignments are not tracked and analysis is incomplete
- ⚠ SDK configuration is fetched asynchronously at startup — agents must await initialization before making flag decisions to avoid default values being returned
- ⚠ Warehouse query costs: Eppo runs SQL against your warehouse for analysis — large experiments with high-cardinality metrics can generate expensive warehouse queries
- ⚠ Subject key (user ID equivalent) must be consistent across assignment and conversion events — agent-generated IDs must be stable and logged correctly to the warehouse
- ⚠ Eppo's feature flag logic runs client-side but assignments are only useful if logged — agents that skip logging for performance reasons break the analysis pipeline
