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.



Deployment & Management

SSH Tunneling for data stores

‏‏‎ ‎‏‏‎ ‎
Securely send data to your data store via SSH tunneling.

Single-tenant cloud deployment option
RudderStack enterprise customers can choose a single-tenant cloud deployment.

Managed VPC deployment option
RudderStack and Segment support VPC deployments.

System health & alerting
RudderStack and Segment both offer system health and notification functionality, but take different approaches.

Basic email notifications

System health and custom alerts via dedicated Grafana dashboards & your alerting system of choice

Basic email notifications

Basic system health via the Segment UI

Connection config management
RudderStack and Segment allow you to manage your connections config via API, but take different approaches.

Via Terraform

Via Segment’s config API

EU data center
Both RudderStack and Segment offer



Data Governance & Privacy

As with many features, RudderStack and Segment both offer features to help you manage data governance and privacy, but take different approaches. You’ll see lots of checks below since RudderStack and Segment can do similar things in this category, but the devil is in the details.



Data Governance & Privacy

Tracking plans
Both RudderStack and Segment’s offer tracking plans.

⚠️ Via Protocols (paid add-on)

Fixing bad data
RudderStack and Segment both allow you to fix bad data, but take different approaches.

Implemented via code

Implemented via UI

Event replay
Both Segment and RudderStack offer event replay features, but with RudderStack, you can replay events from your own data store.

⚠️ Available only in Segment’s Business Tier

Event metadata reporting
Access rich event metadata, including versioning, key counts and more, via API

Code linting for instrumentation
RudderStack’s RudderTyper is very similar to Segment’s Typewriter. The only difference is that RudderTyper is available on all plans.

⚠️ Via Protocols (paid add-on)

Both Segment and RudderStack support GDPR compliance and user deletion, but RudderStack doesn’t store data.

RudderStack has been HIPAA-compliant since 2020 as no customer data is stored. Segment announced their HIPAA feature in November 2022 - currently in beta.


Both Segment and RudderStack offer SSO.

User Profiles & Audiences



User Profiles & Audiences

User identification
Both RudderStack and Segment offer user identification via SDKs and the identify method

Identity resolution
Both RudderStack and Segment offer identity resolution functionality. Again, RudderStack enables this in the warehouse and Segment does this behind the scenes in their platform.


Black-box with UI

User profiles
Both RudderStack and Segment offer user profile creation. RudderStack enables this on the warehouse, whereas Segment forces users into a UI.



Computed user traits
RudderStack can activate any trait you compute in your warehouse. Segment primarily leverages their UI, with limited warehouse trait creation functionality.

Built by you in your warehouse

Audience building
RudderStack and Segment both offer audience creation capability. RudderStack does this on top of your warehouse, where Segment requires you to build in their UI.

Built directly on your warehouse data

Sales and Customer Success teams

Give your sales and support teams superpowers by delivering the complete customer profiles from your data warehouse directly to Salesforce, Hubspot, Zendesk or another CRM tool, so they’ll never perform outreach or schedule a call without the relevant context.

Product Teams

Collect data from all of your web and mobile apps with our high performance SDKs, enrich the data in your warehouse, and serve it to product analytics tools to drive customer insights and help your team build a deep understanding of the customer journey to increase retention and drive a smarter product roadmap.

Marketing teams

Support marketing with the data and insights they need to drive campaign performance, deliver effective personalization, and improve customer experience.

Example: Marketing wants to enrich new customer profiles from an internal Redis data store

Segment’s pricing is based on monthly tracked users (MTUs), while RudderStack charges on event volume. An event can be any single user interaction, for example, a user log-in, an order complete, or a page view. The challenge with the MTU approach is if you have a product or company that has many users but not many conversions (e.g., a media company that drives a lot of content views). Segment will price each user into their pricing model even if they’re not generating revenue for your company. RudderStack charges only for the events.

No. Unlike Segment, RudderStack does not store your data. Our warehouse native approach allows our customers to build their customer data platform in their warehouse of choice.

RudderStack offers both an open source and a cloud option for tracking events. You can find a detailed comparison of these two options on the RudderStack Cloud vs. Open Source page of our docs site.

Not a problem. RudderStack also works with Data Lakes and hundreds of destinations. Check out our catalog of integrations to see which providers we support.
