Which to choose
Choose GrowthBook if
- want an open-source platform with the option to self-host for privacy and compliance
- prefer predictable per-seat pricing starting at $40 per seat each month
- use AI coding assistants like Cursor, Claude Code, or OpenAI Codex
- need contextual bandits alongside Bayesian and Frequentist statistical models
Choose Statsig if
- want built-in session replay linked directly to feature flags and experiments
- prefer usage-based pricing over paying for individual user seats
- need developer integrations with GitHub, VSCode, Vercel, and Datadog
- want to combine web analytics, product analytics, and holdouts in one tool
Verdict
GrowthBook and Statsig both provide warehouse-native experimentation, feature flags, and product analytics for engineering, data, and product teams. GrowthBook suits organisations that value open-source flexibility, self-hosting options, and predictable per-seat pricing. It also integrates directly with AI coding assistants like Cursor and Claude Code. The trade-off is that self-hosting requires internal infrastructure setup, and features like multi-arm bandits sit on higher tiers. Statsig suits teams looking for an all-in-one cloud or warehouse-native suite that adds session replay and web analytics to testing and feature management. Its usage-based model works well if you want to avoid per-seat fees, though heavy event traffic can make monthly costs variable, and non-technical users may face a steeper onboarding curve.
