- What is Segment?
- Segment is a customer data platform that collects product and marketing events once and forwards them to other tools.
- What does it do?
- Takes events from web, mobile and server SDKs, applies a tracking schema, and fans them out to analytics, ads, CRM and warehouse destinations. Also builds unified user profiles and audiences to sync back.
- Who is it for?
- Product, growth and data teams running enough tools that instrumenting each one separately has become the problem. Not worth the setup for one site with a single analytics script.
- What are the alternatives to Segment?
- RudderStack is the warehouse-first, self-hostable equivalent; PostHog bundles analytics and pipelines in one product; June is a lighter B2B analytics layer; Freshpaint focuses on privacy-sensitive collection.
