RudderStack vs Segment
It’s time to take a modern approach to your customer data platform, and say goodbye to legacy CDPs that charge you a premium to store your data in a black box.
40,000+ sites and apps run RudderStack
Modern data teams replace Segment with RudderStack
RudderStack is the only end-to-end Segment alternative. Put your own warehouse or data lake at the center of your data stack and increase the value of your existing architecture, eliminate unnecessary cost and compliance risks, and take control of your customer data with RudderStack’s warehouse native CDP.
Why choose RudderStack?
Built for data teams
RudderStack is open source and built for data teams including Github integrations and an API-first approach to data collection and management, so you can seamlessly integrate it with your existing stack and workflow.
Warehouse native platform
RudderStack treats your warehouse or data lake as a first class citizen. Easily build complete profiles in your warehouse, enrich and transform data for endless use cases, activate warehouse data across downstream tools, and turn your warehouse into your single source of truth.

RudderStack doesn’t store any data, reducing data privacy and compliance (GDPR, CCPA, etc) risks and giving you full ownership of your data. Collect first-party data from any source, transform and enrich data, solve identity resolution and more - all in your warehouse or data lake.
Support for data warehouses and data lakes

"With RudderStack, we not only saved significant costs but also gained powerful capabilities that were previously out of reach with Segment."
James Richter, VP of Engineering at Kajabi
We’re API compatible with Twilio Segment
You can use all of your existing data pipeline instrumentation and everything will just work (including warehouse schemas!) Simply switch the SDKs and update analytics to rudderanalytics.
We’ll automatically migrate your anonymousIDs
RudderStack will automatically grab the Segment anonymousId and send it in our payload, so you won’t have any data inconsistency or interruption in downstream tools. When migration is complete, just remove the Segment SDK.
"When it came down to deciding the right solution, there wasn’t a question. We chose RudderStack as the foundation for our warehouse native customer data platform to enable data-driven personalized engagement online"
Chris Frye, Director of Digital Architecture

Deployment & Management
When it comes to deployment, RudderStack and Segment differ significantly. Segment users all run in a multi-tenant cloud environment. While most RudderStack customers (even in high security industries) run RudderStack’s cloud product because we don’t store data, we offer multiple additional deployment options for enterprises with specific security needs (more detail below). Both companies offer EU data centers.
RudderStack and Segment both offer functionality for system health observability, notifications and managing configs, but take different approaches. RudderStack prioritizes tools already used by and familiar to developers, like Grafana and Terraform.
