RudderStack is an open-source customer data platform with transparent, event-based pricing starting at $220/month, offering 200+ pre-built destinations and a warehouse-native architecture for managing first-party customer data.

RudderStack provides a warehouse-native CDP with transparent event-based pricing that differs from competitors like Segment. The platform charges only for events processed, with a free tier covering 250,000 events/month with full feature set including 200+ destinations. The Starter plan costs $220/month and is recommended when scaling past 1M events/month. RudderStack's pricing structure remains deliberately transparent compared to enterprise vendors, with commonly negotiated discounts of 20-35% below list pricing for multi-year commitments. The warehouse-native architecture and self-hosted deployment option result in lower total cost of ownership at very high volumes, as buyers can optimize infrastructure costs directly.
