Supermetrics alternatives: six connectors by how they count accounts

Supermetrics alternatives: the short answer

The six alternatives to Supermetrics here are Windsor.ai, Porter Metrics, Coupler.io, Dataslayer, Power My Analytics and Funnel (Funnel.io). Supermetrics counts accounts per data source, and each alternative counts them another way, so the table names the unit. Windsor.ai Basic is $19 a month billed annually or $23 monthly, as read on October 24, 2026.

Supermetrics' own price is on its page; the view read for this guide showed no US-dollar figure.

How Supermetrics counts accounts per source and sells extras

On Starter, Supermetrics allows 2 data sources and 1 user, with 2 accounts per data source, meaning the accounts you can connect to each source. Growth lists 7 data sources, 2 users and 7 accounts per data source. Each plan includes 1 core destination: one of ChatGPT, Claude, Copilot, Looker Studio (Google now calls it Data Studio), Google Sheets, Excel or Power BI.

Warehouse destinations such as BigQuery, Snowflake and Redshift are listed under Enterprise. Each extra destination, user, data source or ad account is bought singly up to a cap; Growth's ad-account extra stops at 20 in total.

Its documentation says the subscription decides how often a scheduled refresh can run in Google Sheets: weekly, daily or hourly. These figures come from Supermetrics' own page, not from Windsor.ai's comparison page.

Windsor.ai: one account total and every destination

Windsor.ai counts data sources and one account total across all of them. Basic covers 3 data sources and 75 accounts. Standard, $99 a month billed annually or $118 monthly, covers 7 data sources and 75 accounts with hourly syncs. Plans are sized by sources and accounts, not by data volume, and every destination, BigQuery included, is on every plan.

That matters for BigQuery, which Supermetrics lists under Enterprise. An in-house marketer loading one Facebook Ads and one Google Ads account into BigQuery has 2 data sources and 2 accounts on Windsor.ai, well inside Basic, with loads daily on Basic and hourly from Standard. Google lists its own Google Ads transfer as a no-charge connector; how to connect Facebook Ads to BigQuery covers the paid Facebook Ads transfer.

Porter Metrics and Coupler.io: pay as accounts grow

Porter Metrics bills each connected account on a sliding scale. Its FAQ's monthly schedule starts at $15 for 1 account, $30 for 2 and $39.99 for 3, then $8 each from 5 to 12 accounts and a flat $100 from 13 to 20. Paying annually gives two months free: 1 account is $12.50 a month. See Windsor.ai vs Porter Metrics.

Coupler.io caps accounts and destinations by plan. Starter is $24 a month billed annually ($32 monthly) for 3 accounts and 1 destination, and Pro is $199 ($259 monthly) for 50 accounts. An extra account adds $4.49 on annual billing or $5.99 on monthly billing.

Dataslayer, Power My Analytics and Funnel

Dataslayer's Starter plan covers 3 connectors with 3 accounts each and 1 user. Its core destinations (Sheets, Excel, Looker Studio and Power BI) have unlimited rows on paid plans, while BigQuery, an enterprise destination, is capped at 5,000 rows a month on Starter.

Power My Analytics caps Business at 5 sources and 5 accounts in total. Its pricing page lists exports and hourly refresh as add-ons without a price, and its help center says exports are for Custom plans and a standard sync runs once a day at midnight.

Funnel measures capacity in flexpoints, its own unit: 5 for each account, 50 for each connector. Its pricing page shows annual billing only and no US-dollar figure on the view read for this guide.

Free and cheap Supermetrics alternatives

Supermetrics lists a 14-day trial and no free plan. Porter Metrics keeps unlimited connected accounts on its free plan, Dataslayer keeps 1 connector and 1 account, and Coupler.io keeps 1 account. A Windsor.ai free account gives 30 days of extra capacity, then a Forever Free plan, with the Terms saying trial access ends.

Of the five with a US-dollar price, entry prices on annual billing run from Porter Metrics at $12.50 a month for 1 account, to Windsor.ai Basic at $19 for up to 75 accounts across 3 sources, Coupler.io Starter at $24 for 3 accounts, Dataslayer Starter at $35 for 3 accounts per connector and Power My Analytics Business at $41.63 for 5 accounts in total.
