What it really isA B2B SaaS attribution platform: pixel, server-side tracking and CRM sync that tie ad spend to revenue.
Our takeCometly bundles tracking, five attribution models, Conversion API and AI ad tools, and connects to HubSpot, Salesforce and Stripe so you can see revenue, not just clicks.
It is a sales-led purchase: no public prices, no free trial, and API, MCP and warehouse sync are Enterprise features.
Why we rate itIt covers the full attribution chain, from pixel to CRM pipeline to Stripe revenue, and sends that data back to the ad platforms that need it.
The catchYou cannot see a price without a sales call, there is no free trial, and the developer features (API, MCP, warehouse sync) are Enterprise-only.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Setup is needed: install the Comet Pixel and connect ad, CRM and billing accounts; Cometly says hours, not weeks.
  2. Scale breakpoint
    Pricing rises with monthly pageviews; API access and warehouse sync require Enterprise.
  3. Walled garden
    Moderate: data export to Snowflake and BigQuery and the API are on Enterprise only.
Still a fit?
If none of these block you, try it on the official site.

Is Cometly worth the investment?
