The product

Built for the engineer
who has to answer the question.

Most analytics tools are dashboards with a SQL editor bolted on. Overlay starts with the SQL editor - and gives you dashboards, replay, and experiments built on the same engine.

  • Real-user funnels

    Drop a snippet, get every funnel you can dream of. Slice by cohort, plan, country, anything in your warehouse.

  • Session replay

    See every click, scroll, and rage-quit. Privacy controls bake every PII redaction into the SDK, not the dashboard.

  • Warehouse-native

    Snowflake, BigQuery, Redshift, Postgres. Query our event store from your warehouse without ETL.

  • Retention cohorts

    Drop in any cohort definition in SQL or chips. Watch week-on-week, month-on-month, all the way out.

  • SQL editor

    Full SQL access from day one. Saved queries, scheduled reports, dashboards built on the same engine.

  • A/B framework

    Built-in feature flags + experiments. Roll out by user, by cohort, by warehouse query. Stop at significance.

How it works

From npm install
to first funnel in under 10 minutes.

  1. 01

    Drop the snippet.

    One npm install, one line of code. Or load it via script tag - your call.

    npm i @overlay/sdk

import { track } from '@overlay/sdk';
track('checkout_started', { plan: 'pro' });
  2. 02

    Define cohorts.

    In chips or in SQL. Saved cohorts work in funnels, replay, retention, everywhere.

    cohort: active_paid_users
  WHERE plan != 'free'
    AND last_seen > NOW() - 14
  3. 03

    Answer the question.

    Funnel converts X percent for cohort Y last month. Replay the drop-offs. Ship the fix.

    SELECT step, COUNT(*) 
FROM funnel('checkout', cohort:active_paid_users)
GROUP BY 1

Customer story

“We replaced three tools with Overlay in a weekend. Our engineers stopped asking the data team for funnels - they just answer the questions themselves now.”
