Frequently Asked Questions
Which CDP has the more generous free tier? +
RudderStack's free tier is more generous: it includes 250,000 events/month plus 200+ destinations and Reverse ETL. Segment's free tier is capped at 1,000 monthly tracked users and just 2 destinations, making it more of a trial experience than a usable production tier.
Is it hard to migrate from Segment to RudderStack? +
RudderStack's SDKs are designed to be API-compatible with Segment's, which is meant to lower the switching cost for teams already instrumented with Segment's tracking calls. RudderStack also publishes its own migration-focused comparison content against Segment.
Can I self-host either of these CDPs? +
RudderStack offers a source-available, self-hostable core under the Elastic License 2.0 — you can run it on your own infrastructure, though you'll need to manage PostgreSQL and scaling yourself. Segment has no self-hosting option; it's a fully managed, closed-source SaaS product only.
