Seline

Questions the listing answers

What is Seline and what does it do?

Seline is a lightweight, privacy-first SaaS analytics tool that combines marketing-site analytics, product/event tracking, and revenue attribution into a single workspace. It uses a small (~2KB) tracking script to follow visitors from first visit through product usage and payments so you can build funnels, profiles, journeys, and view revenue attribution in one dashboard.

How do I install Seline on my website or web app?

Install Seline by adding the provided script tag to your site (the docs show a snippet using data-token="PROJECT_TOKEN" and src="https://cdn.seline.com/seline.js"), then call seline.track and seline.setUser from your product as needed. The docs provide the exact script snippet and installation options.

How do I send custom events to Seline?

Send custom events from client or server code using the seline.track method (for example seline.track("user: signed up", { ...properties })). The custom-events docs show examples and explain how to attach properties to events for later analysis.

How can I track revenue and connect Stripe to Seline?

You can track revenue either by connecting Seline’s Stripe integration (recommended for profiles) or by sending revenue events directly with seline.track (including revenue: true, currency, and amount). Seline will attribute revenue to UTMs/referrers and show MRR/attribution in the dashboard; the docs explain configuration and currency settings.

How does Seline identify and merge user profiles?

Seline creates profiles when you send authenticated user data (using seline.setUser). Users are merged by userId or email; sending these identifiers builds a profile with traits, events, and full session history for funnels, churn/engagement filters, and Stripe-linked revenue features.

How do I track visitors across subdomains (e.g., app.example.com and www.example.com)?

To enable cross-subdomain tracking, add the Seline script with a project token to each subdomain you want tracked. Installing the script on each hostname allows Seline to combine sessions and avoid unwanted hostnames appearing in filters.
