- want a free option or transparent per-seat pricing starting at $40 per seat per month
- work in a product, data science, or engineering team using AI coding tools like Claude Code or Cursor
Choose Optimizely if

Verdict
GrowthBook suits product, data science, and engineering teams that want open-source, warehouse-native experimentation and feature flagging. It connects directly to existing data warehouses without duplicating data, and offers a free tier alongside $40 per seat monthly pricing. Optimizely is built for enterprise marketing and product teams that need a broader digital experience platform combining content management, e-commerce, personalisation, and experimentation under quote-based pricing. The main trade-off is focus versus breadth: GrowthBook centres on technical experimentation and direct warehouse queries, though self-hosting requires internal maintenance, whereas Optimizely bundles full marketing and commerce suites at the cost of higher administrative complexity and custom enterprise pricing.
