What Cometly Does
Cometly is an ad attribution platform built around first-party tracking. Its core product is a server-side pixel that captures conversion events and routes them back to Meta and Google Ads despite browser-level privacy restrictions. The platform surfaces revenue attribution per ad, ad set, and campaign.
Cometly's primary use case is fixing broken attribution caused by iOS 14+ changes, cookie blocking, and ad blockers. Teams use it to see which ads are actually driving conversions that Meta's native reporting under-counts.
Cometly Core Features

- Meta and Google Ads reporting
- Customer journey tracking
Cometly Limitations
- Attribution reporting only — no campaign execution
- Primarily Meta and Google focused
- No AI Agent capabilities
- No multi-platform campaign management
- Manual campaign changes still required in ad managers
Synter vs Cometly: The Core Difference
Attribution vs execution
Cometly tells you what worked. Synter does the work. Synter includes server-side conversion tracking (Conversions API, GA4 integration), but its primary capability is AI Agents that create campaigns, adjust budgets, and optimize performance directly in your ad accounts across 14 platforms. Cometly has no execution layer.
Teams that already run campaigns efficiently but struggle to know which ads are actually converting benefit most from Cometly. Teams that want to reduce the manual work of running campaigns across multiple platforms benefit more from Synter.
