GrowthBook

GrowthBook is a powerful open-source platform for feature flagging and A/B testing that enables engineering and product teams to ship code confidently and measure the impact of every change. Unlike expensive SaaS solutions, GrowthBook gives you complete control over your experimentation infrastructure while providing enterprise-grade statistical analysis. The platform has gained significant adoption with thousands of companies using it to run experiments and manage feature rollouts.

Common Use Cases

Product teams use GrowthBook to run controlled experiments on new features, measuring conversion rates, engagement metrics, and revenue impact before full rollout. Engineering teams leverage feature flags for gradual deployments, canary releases, and instant rollbacks without code deployments. Growth teams analyze user behavior across segments to optimize onboarding flows, pricing pages, and marketing campaigns. Data teams appreciate the warehouse-native approach that keeps experiment data in their existing infrastructure rather than siloed in a third-party tool.

Key Features

• Advanced feature flags with targeting rules, percentage rollouts, and prerequisite flags
• A/B testing with Bayesian and frequentist statistical analysis methods
• CUPED variance reduction for faster, more accurate experiment results
• Sequential testing to stop experiments early when results are conclusive
• Multi-language SDKs: React, JavaScript, Python, Go, Ruby, PHP, iOS, Android, and more
• Data warehouse integrations: BigQuery, Snowflake, Redshift, PostgreSQL, ClickHouse
• Visual experiment editor for no-code A/B tests on web pages
• Segment analysis to break down results by user attributes
• Metric library for reusable experiment goals and guardrails
• REST API and webhooks for custom integrations and automation

Why deploy GrowthBook on Hostinger VPS

Deploying GrowthBook on Hostinger VPS provides complete ownership of your experimentation platform and data. Unlike SaaS alternatives with per-seat pricing, self-hosting enables unlimited team members and experiments at a fixed infrastructure cost. Your experiment configurations, feature flag states, and analysis results remain on your infrastructure, ensuring data privacy and compliance. The VPS environment delivers consistent performance for the statistical computations required for experiment analysis, while the Docker deployment simplifies updates and maintenance. For teams running sensitive experiments or operating in regulated industries, Hostinger VPS offers the control and security that cloud-hosted solutions cannot match.
