Windsor.ai alternatives: six connectors by meter and price

Windsor.ai alternatives: the short answer by meter

The six alternatives to Windsor.ai are Porter Metrics, Coupler.io, Dataslayer, Power My Analytics, Supermetrics and Funnel (Funnel.io). They send ad data to Looker Studio (Google now calls it Data Studio), Google Sheets and BigQuery, and they differ in what they count.

Windsor.ai counts data sources, the platforms data comes from, and one shared account total. Basic is $19 a month billed annually or $23 on monthly billing for 3 data sources and up to 75 accounts, as read on October 24, 2026. The table gives each alternative's entry price billed annually, with the monthly figure where its page shows one.

Pay by the account: Porter Metrics

Porter Metrics bills each connected account, with volume tiers. On monthly billing its FAQ lists 1 account at $15, 2 at $30, 3 at $39.99 and 4 at $40, then $8 an account from 5 to 12. Annual billing takes off two months, so 1 account is $12.50 a month, billed $150 a year.

Porter's free plan keeps unlimited connected accounts with 30 days of history, and its MCP for Claude and ChatGPT is in every plan. Its FAQ says refunds are available within 14 days of purchase, where Windsor.ai's Terms allow none. The limit is the meter: a connected account counts whether or not it spent. See Windsor.ai vs Porter Metrics.

Plans by source or connector: Supermetrics, Dataslayer and Power My Analytics

Supermetrics Starter lists 2 data sources, 1 user and 2 accounts per data source, with 1 core destination (a reporting tool, spreadsheet or AI chat); Growth lists 7 data sources and 7 accounts per data source. Extras are sold singly per destination, user, data source and ad account, each with a cap. Warehouse destinations such as BigQuery sit under Enterprise.

Supermetrics' price is on its own page. See Windsor.ai vs Supermetrics.

Dataslayer Starter lists 3 connectors, 1 user and 3 accounts per connector with a daily refresh; Advanced, $115 a month billed annually, allows 7 connectors with 50 accounts each and hourly refresh. Sheets, Excel, Looker Studio and Power BI are core destinations with unlimited rows on paid plans. BigQuery is an enterprise destination with a monthly row cap, 5,000 rows on Starter. See Windsor.ai vs Dataslayer.

Power My Analytics Business lists 5 sources and 5 accounts in total, without Sheets or Excel; Grow lists unlimited sources and 7 accounts per source, with both. Its pricing page lists exports and hourly refresh as add-ons and gives no price there, while its help center says exports are for Custom plans.

An account total with extras: Coupler.io

Coupler.io caps accounts and destinations by plan. Starter has 3 accounts, 1 destination, a daily refresh and 5,000 rows a run. Active, $99 a month billed annually or $132 monthly, has 15 accounts and 3 destinations. Pro, $199 billed annually or $259 monthly, has 50 accounts, unlimited destinations and an hourly refresh.

Extra accounts cost $4.49 each on the annual view and $5.99 on the monthly view. Every source and destination is on every plan, and Coupler.io says annual billing saves 25%. The limit is rows: Starter exports at most 5,000 rows a run and the Free plan 100.

Funnel: flexpoints and annual billing shown

Funnel sizes plans in flexpoints, its word for purchased capacity: 50 per connector, 5 per account, 150 per visualization destination such as Looker Studio or Google Sheets, and 300 per warehouse destination such as BigQuery. Starter lists 117 connectors and 13 destinations with daily exports. Business lists 579 connectors and 46 destinations with exports every 2 hours.

Funnel's pricing page shows annual billing only, and the view read for this guide showed no US-dollar figure, so the price is on Funnel's page. Agency pricing is by quote. Funnel says it does not charge by rows.

Free alternatives and when Windsor.ai still fits

Three alternatives keep a free plan after the trial. Porter Metrics keeps unlimited connected accounts with 30 days of history. Dataslayer keeps 1 connector, 1 user, 1 account and 1 manual refresh a day. Coupler.io keeps 1 account with manual refresh. Windsor.ai's Forever Free plan keeps 1 source and 1 account, with the Terms saying trial access ends.

Funnel's trial runs 30 days, like the 30 days of extra capacity on a Windsor.ai account. Porter Metrics, Supermetrics and Power My Analytics give 14 days, Dataslayer 15 and Coupler.io 7.

Google's own transfers can replace a connector for Google Ads and GA4 data in BigQuery: Google lists both as no-charge connectors, with BigQuery storage and queries billed beyond the free tier. Windsor.ai still fits many accounts across a few platforms, with every destination on every plan and Basic's 75 accounts counted as one total.
