Best Supermetrics Alternatives in 2026: Audited Pricing & Picks

Last verified: October 9, 2026

Switch from Supermetrics if your stack is small and stable: the per-source, per-user and per-destination pricing that justifies 300-plus connectors for a growing agency just adds line items you don't need for three or four accounts. Getting the advertised rate also means prepaying annually, and several long-time customers report their bill roughly doubling to tripling within a couple of years. We priced five alternatives against their live vendor pages to find out which ones actually cost less for a smaller stack.

ToolsGavel's top pick: Windsor.ai (3.9/5, from $23/mo) — Basic costs $23 a month for 3 sources with unlimited users built in, where Supermetrics' comparable Starter tier runs €49 a month and still bills extra users and a second destination separately. Hourly refresh still needs the $118 Standard tier, though, and once the 30-day trial ends, the permanent free tier shrinks to one source.

#1
Windsor.ai Flat-rate pick for Looker Studio
3.9

Basic costs $23 a month for 3 sources with unlimited users built in, where Supermetrics' comparable Starter tier runs €49 a month and still bills extra users and a second destination separately. Hourly refresh still needs the $118 Standard tier, though, and once the 30-day trial ends, the permanent free tier shrinks to one source.

Best for: Growing teams and small agencies who want one predictable monthly price across sources and seats, plus built-in attribution modeling instead of a bolt-on tool · from $23/mo

#2
Coupler.io Best for Google Sheets teams
3.9

The free plan pulls one real account into one destination with no expiration date, and Starter runs $32 a month for 3 accounts once you need daily refresh and a bigger row cap. Add clients past that and the cost catches up fast. Every extra account past the plan limit costs $5.99 a month on top, where Supermetrics charges per source, user and destination instead of per account.

Best for: Small teams and agencies that want to test a real connector for free before paying, then scale reporting without a per-seat bill · from $32/mo

#3
Porter Metrics Best for lean agency budgets
3.8

Solo runs $14.99 a month for one account, and the permanent free plan covers 3 accounts with every destination and feature unlocked, a lower floor than anything else here, including Supermetrics, which has no free tier at all. The trade-off is depth. Porter covers around 50 connectors next to Supermetrics' 300-plus, and delivers raw API fields instead of pre-built calculated metrics.

Best for: Solo marketers and small agencies who need a handful of ad accounts flowing into Looker Studio without paying for 300 connectors they'll never use · from $14.99/mo

#4
Databox Best if you want dashboards, not just pipes
4.1

The free plan includes 1 dashboard on top of 3 data sources, and Analyst starts at $64 a month billed annually for 5 sources, a dashboard and goal-tracking layer Supermetrics doesn't build for you. You're buying a BI tool here, not a bare connector, so advanced custom metrics still need some query know-how and cost still climbs as you add sources.

Best for: Teams that want live business dashboards without building them from code · from $71/mo

#5
Funnel.io Enterprise-grade, not cheaper
3.8

Starter lists at $300 a month for 121 connectors, but ships zero export destinations, so the warehouse feed that justifies the price only turns on at the $600-a-month Business tier, both well past what Supermetrics charges for a comparable connector count. Funnel earns a slot here for governance and warehouse depth, not for saving money versus Supermetrics.

Best for: Marketing teams and agencies managing dozens of ad accounts who need a governed data warehouse feed, not just a dashboard connector · from $300/mo

Why look for a Supermetrics alternative?

Supermetrics bills sources, users and destinations as separate line items. Starter runs €49 a month for 3 sources, 1 destination and 1 user, and each additional source, seat or destination adds cost on top of that base rate. Locking in the discounted price also means prepaying annually; staying month-to-month costs more per month than the advertised figure. That structure rewards an agency running a long client roster across many platforms, where 300-plus connectors earn their keep. It rewards a small, stable stack a lot less. Several long-time Supermetrics customers report their bill roughly doubling or tripling over a couple of years without a matching jump in features, which is worth knowing before you sign an annual contract to get the lower rate.

How we compared them

We read each tool’s live pricing page, plan comparison and documentation against the same rubric, in October 2026, the same week we re-verified Supermetrics’ own numbers. We didn’t trial any of these five hands-on; every price and feature claim below traces back to what the vendor publishes. Full method: how we test. The same figures sit alongside dozens of other audited tools in the Pricing Gap Index, and the wider six-tool field, including Power My Analytics, is in our marketing reporting connector roundup.

Windsor.ai: flat pricing with attribution built in

Pick Windsor.ai if a predictable bill matters more than the deepest connector list, or if multi-touch attribution modeling (first-click, last-click, linear, Markov, algorithmic) is actually on your to-do list; it ships on every plan instead of needing a separate tool. Full review. It falls short on refresh speed for a tight budget. Hourly sync needs the $118 Standard tier, and 15-minute sync only unlocks on the $598 Professional plan.

Coupler.io: the only free plan with real data

Coupler.io earns its spot on real data. The free plan moves one real account into one destination, not a sample dashboard, so you can confirm a connector pulls the right fields before a card gets charged. Full review. Once your client roster grows past a handful of accounts, though, the $5.99-a-month per-account add-on catches up faster than a flat-rate tool would.

Porter Metrics: the cheapest way into Looker Studio

If your whole stack already reports into Looker Studio, Sheets, BigQuery or Power BI and you’re only running a handful of accounts, Porter Metrics is the cheapest way in. Solo starts at $14.99 a month, and the free plan covers 3 accounts with no expiration date. Full review. Step outside the mainstream ad and analytics stack, though, and the gap shows up fast. At around 50 connectors, Porter’s library is a fraction of Supermetrics’ 300-plus.

Databox: the dashboard comes built in

Databox solves a different problem. The goal here is a live KPI dashboard, not a data pipe someone still has to turn into a report later. Templates, goal tracking and alerts come built in, and the free plan includes an actual dashboard, not just a connection. Full review. A team that already has a Looker Studio or warehouse dashboard built should skip it; you’d be paying for a BI layer nobody touches.

Funnel.io: costs more, not less

Funnel.io only pencils out once you’re already running ad spend across dozens of platforms and need a governed warehouse feed more than a lower bill. Business starts at $600 a month for 579 connectors and 26 export destinations. Full review. Skip it if saving money is the whole point. Starter alone costs $300 a month with no export destination included, and Flexpoints usage billing tends to push real invoices toward four figures a month.

What Supermetrics still does better

Connector breadth is the one place none of these five fully catch up. Supermetrics covers 300-plus sources spanning paid media, organic social, SEO tools, ecommerce, CRM data and affiliate networks, and reviewers, including non-technical marketers, consistently rate its setup and connector reliability highly. The AI credits bundled into every paid tier, not only the top one, add query-level summaries most of these alternatives skip entirely. If your account list is genuinely long and reaches platforms outside the mainstream ad stack, that depth is still the reason agencies default to Supermetrics first.

Is there a free Supermetrics alternative?

Supermetrics itself has no permanent free plan, only a 14-day trial with no card required. Four of the five alternatives here do: Windsor.ai’s Forever Free tier (1 source, 1 user, no expiration), Coupler.io’s free plan (1 account, 1 destination, manual refresh, 100 rows per run), Porter Metrics’ free tier (3 connected accounts, every destination and feature, no expiration), and Databox’s free plan (3 data sources, 1 user, 1 dashboard). Funnel.io is the one exception. Like Supermetrics, it has no free tier at all.

Which one should you pick?

  • Solo marketer or two-person shop, Looker Studio only: Porter Metrics, from $14.99 a month, or the free plan if 3 accounts covers it.
  • Growing team that wants one predictable bill as headcount rises: Windsor.ai, from $23 a month with unlimited users on every tier.
  • Team that wants to test a connector before paying for it: Coupler.io’s free plan, then $32 a month once you outgrow it.
  • Team that wants a finished dashboard instead of raw piped data: Databox, from $64 a month, free plan included.
  • Agency or marketing org already running spend across dozens of platforms: stay on Supermetrics for the connector breadth, or move to Funnel.io once a governed warehouse feed matters more than price. Our Supermetrics vs Funnel.io comparison covers that trade-off in detail.
  • Destination is Looker Studio only: our Looker Studio connectors guide prices every option here for a three-source stack.
