In their own words
Confidence by Spotify
Confidence by Spotify is a warehouse-native platform for experimentation and feature management. Teams can run A/B tests, define metrics in their warehouse, manage feature flags, and use product data to guide decisions. Experimentation tools include sequential testing, automatic guardrails, and CUPED variance reduction. Rollouts can ramp releases from 1% to 100% while guardrails monitor for regressions, with one-click reverting. Feature flags include typed schemas, warehouse-powered targeting, and cleanup support; the Free plan includes unlimited flags and seats. Analytics accepts plain-English questions and returns charts and causes grounded in experiments, metrics, and warehouse data. Every account receives a managed warehouse, while paid plans can connect BigQuery, Snowflake, Redshift, and Databricks, with analysis in inspectable SQL. Session Replay overlays real user sessions with flags and experiment variants. The service is built on the OpenFeature API and offers migration kits to rewrite competitor SDK code to that standard. Pricing includes a Free plan with 75,000 credits per month and Growth at $449 a month. A 30-day trial is listed.
