What it costs
Core and Enterprise are quoted from monthly pageviews (vendor estimates pageviews at about 1.5× sessions). No dollar amounts on the pricing page. Monthly or annual billing; annual saves 20%. No free trial; Professional Onboarding replaces a self-serve trial. Past pageview limit: attribution is never throttled; notice at 90% and automatic promotion to the next tier at the next billing period.

What works
- Server-side Conversion API is the genuine strength. Cometly sends deduplicated conversions back to Meta, Google, LinkedIn and TikTok, and reports Meta event match quality up to 9.3 out of 10 where a manual setup sits at 4 to 5. Buyers on r/FacebookAds confirm it pushed more matched data to Meta than other trackers they had run.
- Revenue attribution built around Stripe and the CRM, not just clicks. The native Stripe sync ties trials, new customers, recurring revenue and LTV to the originating ad, and HubSpot and Salesforce lifecycle stages map onto the same touchpoints, right through to closed-won ARR. That is the report a SaaS finance team will actually defend.
- Modern data plumbing under it. A cookieless Comet Pixel with cross-device identity, 70-plus native integrations, an Agent you query in plain English instead of writing SQL, and on Enterprise a warehouse sync to Snowflake or BigQuery plus an MCP server that lets an AI agent read your attribution data. The vendor puts setup at hours rather than weeks.
- Established and reviewed, not a new app. Comet LLC has tracked paid spend for years, with named case studies (ClickFunnels reports a 31% ad-return lift, Trainual a 40% improvement in 90 days) and aggregate ratings of 4.8 out of 5 on G2 across 36 reviews and 3.6 out of 5 on Trustpilot across 92.
What to watch
- It is not a route-through campaign tracker. Cometly attributes traffic to your own site and funnel; it does not rotate offers, split traffic across landers by rule, or distribute clicks the way Voluum, RedTrack or Binom do. That matters most to affiliate media buyers running many offers through a redirect. A SaaS team sending paid traffic to one funnel does not need routing.
- It has left the DTC and ecommerce market it once served. Cometly's own site now names Triple Whale as the ecommerce tool and positions itself for B2B SaaS. Shopify still integrates, but reviewers report weaker matching on cash-on-delivery and email-less orders, so an ecom brand should demand proof on its own orders before buying.
- No public price and no free trial. Every plan is usage-based on monthly pageviews and quoted on a sales call, and Cometly says it does not run a trial because attribution needs setup first. Buyers who want to test against their own numbers before paying, or just want a price before a call, get neither. One G2 reviewer wanted more transparent negotiation and flagged pricing changes over time.
- Support and journey timing draw the recurring complaints. The long-running r/FacebookAds thread reports support replies measured in business days and trouble seeing the full pre-purchase journey or getting purchases captured fast enough. The sample is small, but it is consistent enough that you should test response times and event latency during onboarding.
