Datafast does analytics. Admaxxer does analytics + attribution + server-side tracking — same $9/mo.

The triple-stack: what you actually need to run paid acquisition

Most DTC operators end up paying for three separate tools:

1. Analytics — first-party pixel for visitors, sessions, UTM tracking, revenue from Shopify. Datafast and tools like Plausible / Fathom / Simple Analytics ship this for $9–199/mo.
2. Attribution — blended MER, CAPI match rate scoring, cohort LTV at 7/30/90d, Markov-chain attribution, six attribution models, MMM. Triple Whale + Hyros ship this for $129–999/mo each.
3. Server-side tracking — Meta CAPI, Google Enhanced Conversions, TikTok Events API, Pinterest CAPI, Klaviyo server-track, first-party CNAME so cookies survive Safari ITP. Stape ships this for $20–500/mo per store.

Datafast solves layer 1. Admaxxer solves all three — same $9/mo entry tier, scaling to $999/mo at 50M events/mo. One platform, one bill, one data model.

When to choose each

Choose Datafast if…

• You only need a privacy-friendly pixel and you don't run paid ads.
• You're already paying for Triple Whale or Hyros separately and don't want to switch attribution providers.
• Your Shopify connection covers all the revenue analytics you need.

Choose Admaxxer if…

• You run paid ads and need real revenue attribution — not just visitor counts.
• You want server-side CAPI for Meta + Google + TikTok + Pinterest + Klaviyo without a Stape add-on.
• You want first-party CNAME on every plan so Safari ITP and ad blockers don't drop your data.
• You want a single $9/mo bill instead of stitching three tools at $109+/mo.

Competitor pricing reflects publicly listed pricing as of May 2026.

Real cost by store size

If you only buy Datafast, you'll need a Stape-equivalent for server-side tracking and a Triple-Whale or Hyros-equivalent for attribution. Stacked, the math looks like this:

Stape and Hyros pricing is illustrative based on publicly listed pricing as of May 2026 and the typical add-on tier matching the Datafast event quota. See /methodology for measurement definitions.

What Admaxxer ships that Datafast doesn't

Revenue attribution layer

Blended MER, CAPI match rate per pixel + ad account (Q1 2026 average: 92% across 8.4 million events), cohort LTV at 7/30/90d ad-level granularity, six attribution models (last-click, first-click, linear-all, linear-paid, time-decay, position-based) plus Markov-chain causal attribution. The full DTC attribution surface Datafast users typically wire up in Triple Whale or Hyros on top.

Server-side tracking on five platforms

Meta Conversions API, Google Ads Enhanced Conversions for Web, TikTok Events API, Pinterest Conversions API, Klaviyo server-track-events. Pixel + server fire the same conversion with the same event_id so platforms deduplicate automatically. Typically recovers 20–40% of conversions lost to iOS ATT, Safari ITP, and ad blockers. Included on every plan from $9/mo. Datafast users typically pay Stape $20–500/mo for this capability.

First-party CNAME on every plan

Point t.yourbrand.com (or any subdomain) at Admaxxer's Caddy edge. We auto-issue a Let's Encrypt cert per merchant in seconds. Pixel + ingest endpoints serve from your own subdomain — not a shared vendor CDN. Cookies are first-party, requests survive Safari ITP and ad-block lists. Datafast does not offer first-party CNAME.

Maxxer AI agent (BYOK)

Read tools (list campaigns, query metrics, get insights) and destructive-gated write tools (pause low-ROAS, update campaign budget) that require explicit user confirmation. Bring your own API key across 10 providers — OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral, Perplexity, Together, Cohere, OpenRouter — and pay LLM costs at provider pricing with no markup. Plus an MCP server compatible with Claude Desktop, Claude Code, ChatGPT Desktop, Cursor, Windsurf, Codex CLI, Cline, and Zed.

Native Meta + Google + TikTok + Klaviyo ad ops

Paste-token connectors for six platforms. Pause campaigns, scale ad sets, launch new creatives — from inside Admaxxer with confirmation gates and an append-only audit log. Datafast is reporting-only.

Migrating from Datafast — three steps, under an hour

1. Install the Admaxxer pixel. Same first-party-pixel philosophy as Datafast. Paste one snippet in your site head. Pixel fires alongside Datafast — no conflict.
2. Paste your Meta + Google tokens. Tokens encrypted AES-256-GCM at rest. Historical spend backfills via Meta Marketing API + Google Ads API in ~60 seconds.
3. Reconcile and switch. Run both side by side for 7–14 days. When the numbers reconcile, switch DNS for your CNAME and cancel Datafast. Your attribution + server-side tracking come online the moment the pixel installs.

Frequently asked

How is Admaxxer different from Datafast at the same $9/mo?

Datafast is a pixel analytics product — visitor counts, page views, UTM source/medium/campaign, basic revenue from a Shopify connection. Admaxxer is the full triple-stack at the same entry price: pixel analytics + revenue attribution (blended MER, CAPI match rate, cohort LTV 7/30/90d, six attribution models including Markov) + server-side tracking (Meta CAPI, Google Enhanced Conversions, TikTok Events API, Pinterest CAPI, Klaviyo server-track) on your own CNAME. Same price tier, three product categories collapsed into one.

Can I migrate from Datafast without losing my historical analytics?

Yes. Install the Admaxxer pixel alongside Datafast — they don't conflict. Meta and Google spend backfills automatically from their native APIs once you paste your tokens. Revenue history backfills from the Admaxxer pixel from install day. Run both in parallel for 7–14 days to reconcile numbers, then switch.

Does Datafast offer server-side tracking like Meta CAPI?

Not natively. Datafast users typically add Stape ($20–500/mo per store) to forward server-side conversions to Meta CAPI, Google Enhanced Conversions, TikTok Events API, etc. Admaxxer ships server-side conversions forwarding to all five platforms — Meta, Google Ads, TikTok, Pinterest, Klaviyo — included on every plan from $9/mo. Pixel + server fire the same event_id so the platform deduplicates automatically. Typically recovers 20–40% of conversions lost to iOS ATT, Safari ITP, and ad blockers.

Can my Admaxxer pixel run on my own domain like t.yourbrand.com?

Yes. Point a CNAME at Admaxxer's Caddy edge. We auto-issue a Let's Encrypt certificate per merchant in seconds, and your pixel + ingest endpoints serve from your own subdomain — not a shared vendor CDN. Cookies are first-party, requests survive Safari ITP and ad-block lists that target known tracker domains. Included on every plan from $9/mo; Datafast does not offer this.

Does Admaxxer have an AI agent? What about BYOK?

Yes — Admaxxer ships the Maxxer AI agent on every plan, with read tools (list campaigns, query metrics, get insights) and destructive-gated write tools (pause low-ROAS, update campaign budget) that require explicit user confirmation. Operators bring their own AI provider API key (BYOK) across 10 providers including OpenAI, Anthropic, Google Gemini, xAI Grok, DeepSeek, Mistral, Perplexity, Together, Cohere, and OpenRouter. Admaxxer does not fund AI inference at the platform level, so you pay your provider directly at their pricing with no markup.

What about MMM, incrementality, and forecast?

Included on every plan from $9/mo. Admaxxer ships OLS-based MMM with geometric adstock decomposition (Robyn-grade Bayesian on the v1.5 roadmap), two-proportion-z-test incrementality on natural paid-vs-organic cohorts, and OLS forecasting with weekly seasonality. Datafast does not include MMM, incrementality, or forecasting on any tier.
