Attrifast vs Cometly
The Cometly alternative
for everyone who isn't a performance marketer.
Cometly is AI-powered multi-touch attribution at $299+/mo — purpose-built for performance marketers spending $20k+/mo on paid ads. If you're a SaaS founder or small ecommerce store who wants to know which channels drive revenue without a six-figure ad budget, Attrifast is 10x more affordable and takes 2 minutes to set up instead of days.
Free for 7 days, then $9.99/mo. Works with or without paid ads.
What Cometly actually costs relative to ad spend
Attribution tools are only worth the insight they deliver relative to the spend they optimize. Here is the honest math across different ad budget levels.
| Ad Spend Level | Cometly | Attrifast | Cost Ratio |
|---|---|---|---|
| $20k/mo ad spend | $299/mo (1.5% of spend) | $9.99/mo (0.05% of spend) | 30x more |
| $50k/mo ad spend | $799+/mo (1.6% of spend) | $9.99/mo (0.02% of spend) | 80x more |
| $100k/mo ad spend | $1,499+/mo (1.5% of spend) | $9.99/mo (0.01% of spend) | 150x more |
| No paid ads | No value — requires ad data | $9.99/mo — tracks all channels | — |
What Cometly genuinely does better
Cometly is a serious product built for a specific use case. These are the real reasons performance marketers pay $299+/mo for it.
AI-powered multi-touch attribution
Cometly's AI models analyze the full customer journey across multiple ad touchpoints — first click, last click, linear, time decay, and data-driven models. For performance marketers with complex multi-channel funnels, this attribution depth drives meaningful spend optimization. Attrifast uses first/last-touch attribution.
Deep ad platform integrations
Cometly integrates deeply with Meta Ads, Google Ads, TikTok Ads, and other ad platforms — pulling cost data and attribution signals at the campaign, ad set, and ad level. This granularity helps media buyers optimize spend allocation in real time. Attrifast works at the channel level via UTM attribution.
Server-side event matching (CAPI)
Cometly sends conversion events back to ad platforms via server-side APIs (Facebook CAPI, Google Enhanced Conversions), improving ad algorithm optimization signals. This is genuinely valuable for performance marketers who want to improve ROAS through better signal quality.
Ad spend ROAS dashboard
Cometly is built around a media buyer workflow: ROAS by campaign, CPA trends, spend efficiency scores. The interface is designed for people who live in ad dashboards. Attrifast is designed for founders and marketers who want revenue-by-channel answers without ad platform complexity.
If you have a dedicated media buyer running $20k+/mo across Meta, Google, and TikTok, Cometly's AI attribution and CAPI integrations may drive enough ROAS improvement to justify the cost. For everyone else, $299/mo is a lot to pay for attribution data you can get from Attrifast at $9.99/mo.

Three things Attrifast does that Cometly doesn't
Beyond price, Attrifast makes different architectural choices that matter for certain types of businesses.
Revenue Per Visitor (RPV)
Attrifast calculates Revenue Per Visitor for every traffic channel automatically. Instead of just ROAS (ad return), you see which organic channels, email, and direct traffic sources generate the highest revenue per visitor — giving you a complete picture regardless of whether you run paid ads.
Native Stripe integration
Cometly is built primarily around ecommerce conversion tracking. Attrifast natively integrates with Stripe, making it purpose-fit for SaaS businesses, digital products, and subscription revenue — not just one-time ecommerce purchases.
Cookieless by design
Attrifast tracks visitors without cookies — no third-party cookies, no fingerprinting, no cross-site tracking. Cometly uses pixel-based tracking that requires consent management — losing the 30-40% of visitors who decline.
When to choose Cometly vs when to choose Attrifast
Choose Cometly if...
- •You're spending $20k+/mo on paid advertising and the accuracy of AI multi-touch attribution models meaningfully affects your media buying decisions.
- •You have a dedicated media buyer or performance marketing team who needs campaign-level and ad-level attribution data.
- •Sending better conversion signals back to Meta and Google via server-side CAPI is a priority for improving your ad algorithm performance.
- •Your primary question is "how do I optimize my ad spend?" rather than "which channel drives the most revenue overall?"
- •You are running a high-volume ecommerce brand where marginal ROAS improvement from better attribution pays for the $299+/mo easily.

- •Flat $9.99/mo predictable pricing matters more than AI attribution features designed for enterprise ad budgets.
