GA4 Attribution vs the Alternatives, Side by Side (2026)
GA4 removed all attribution models except Data-Driven Attribution in 2023, and DDA needs 400+ conversions per channel to activate. Alternatives: Northbeam ($400+/mo, ML black box for enterprise DTC), Rockerbox (free / $200/mo, strong on podcast and TV), HockeyStack ($2,200+/mo, but exited attribution Q1 2026), Triple Whale ($129/mo, Shopify-only), Dreamdata (free / $999/mo, B2B SaaS), mbuzz (free / $29-299/mo, 8 models side-by-side + Attribution DSL). For technical marketers who want to inspect the model, mbuzz is the only tool that shows all 8 model outputs simultaneously.

The table is the answer. Below is a one-paragraph per tool with the actual trade-off named, then a per-use-case decision guide, then the part most comparison pages won't say out loud.
GA4: free, but one black-box model
GA4 is excellent as web analytics. As attribution, you get exactly one model: Data-Driven Attribution. DDA needs 400+ conversions per channel to activate; below that, GA4 falls back to last-click. The model itself is closed: Google won't show you the weights. Documented bias toward Google channels (Ads, organic Search, YouTube). The killer feature is the price. Zero.
mbuzz: 8 models, write your own
8 attribution models running side-by-side on the same data: first-touch, last-touch, linear, time-decay, position-based, Markov chain, Shapley value, data-driven. The wedge is the spread. If last-touch says Google is 60% of conversions and Markov says it's 35%, the real number lives in that fight between the models. Attribution DSL lets you write or fork any model in a SQL-like language. Server-side tracking closes the 30-40% gap that client-side trackers lose to ad blockers and iOS privacy. Free tier covers solo work; $29-299/mo for teams.
Northbeam: enterprise DTC ML
Used by larger DTC brands with seven-figure monthly media budgets. Sophisticated ML attribution. The trade-off is that the model is a black box and pricing scales to $2-5K/month at volume. If you don't have a dedicated media-buying team to interpret the output, you're paying for a number you can't audit. See Northbeam alternatives for a deeper breakdown.
Rockerbox: multi-channel including offline
The strongest tool on this list for measuring podcast, TV, and direct mail alongside digital. Combines MTA with MMM in one product. Free tier exists; paid plans start ~$200/mo. Fewer attribution models than mbuzz, less platform-specific depth than Triple Whale. Best fit when offline channels are part of your mix. See Rockerbox alternatives.
HockeyStack: bundled B2B, but exited attribution
HockeyStack publicly exited attribution in Q1 2026, repositioning the company around "AI revenue agents." The product still ships, but their 300+ attribution articles are no longer maintained and the company's strategic bet is elsewhere. $2,200+/mo. Picking HockeyStack today for attribution means buying against the vendor's own roadmap. See HockeyStack alternatives.
Triple Whale: Shopify only
Purpose-built for Shopify DTC. Easy install, dashboard-first, fast time to value. $129/mo entry. Shopify-only is the hard limit. No WooCommerce, no Magento, no custom carts. Multiple pricing restructures in 2026, so check current rates before signing. See Triple Whale alternatives.
Dreamdata: B2B journey
Strong on B2B sales-cycle attribution: account-level credit, multi-stakeholder journeys, long attribution windows. Free tier for individuals; paid from ~$999/mo. Closed-model approach (you don't write your own). Best fit for B2B SaaS teams that need account-level attribution and don't need to inspect the math. See Dreamdata alternatives.
Choose by use case
Shopify DTC under $30M revenue. Triple Whale or mbuzz. Triple Whale is faster to set up. mbuzz gives you more models and works beyond Shopify if you grow off-platform.
DTC at $40M+ with offline channels. Rockerbox for multi-channel including podcast/TV, or Northbeam for digital ML attribution.
B2B SaaS. Dreamdata for closed-model account-level attribution. mbuzz for model inspection and custom rules.
Anyone who wants to keep GA4 and add a real attribution layer. mbuzz. The free tier runs alongside GA4. No migration, no rip-and-replace.
Bootstrapped or under $20K/mo ad spend. Stay on GA4 for now and add mbuzz's free tier. Below $20K/mo the conversion sample is too small for any model to settle, so the cheap stack wins.
The part most comparison pages won't say
Every tool above ships with a model baked in and reports its number as if it came from physics. GA4 has DDA. Northbeam has its ML. HockeyStack, Dreamdata, Triple Whale, and Rockerbox each have a proprietary "data-driven" model under the hood. Each one will tell you a different answer on the same touchpoint data.
That's how attribution works. A model is an opinion about how credit moves through the journey, and different opinions weight things differently. The dishonest part is presenting a single opinion as truth.
mbuzz runs eight at once so you can see the spread. If six of the eight models agree on a channel's contribution, that's high confidence. If they disagree by 20 percentage points, you know the answer is a judgement call, not a number to copy off a dashboard.
Compare 8 attribution models on your own data
Run first-touch, last-touch, linear, time-decay, position-based, Markov, Shapley, and data-driven side-by-side. Write your own in the Attribution DSL. Free tier, no credit card.
