Windsor.ai vs Porter Metrics: plans or per-account billing

Windsor.ai vs Porter Metrics: the short answer

Windsor.ai sells plans sized by data sources and accounts, while Porter Metrics bills each connected account. On monthly billing, as read on October 24, 2026, Windsor.ai Basic is $23 for 3 data sources and up to 75 accounts, and Porter Metrics is $15 for 1 account, $30 for 2 and $39.99 for 3.

Pick Porter Metrics for a bill that follows the number of connected accounts, a 14-day refund window and a free plan with unlimited accounts. Pick Windsor.ai for many accounts across a few platforms with every destination on one plan. Both send ad data to Looker Studio (Google now calls it Data Studio), Google Sheets, Power BI and BigQuery.

How Porter Metrics prices by the account

Porter Metrics says it charges per data source account, with volume tiers. Its FAQ lists the monthly schedule: 1 account $15, 2 accounts $30, 3 accounts $39.99, 4 accounts $40, 5 to 12 accounts $8 each, 13 to 20 accounts a flat $100 and 21 to 39 accounts $5 each.

Annual billing is two months free, and the year is paid up front. On the annual view, 1 account is $12.50 a month, billed $150 a year, and 5 accounts are $33.35 a month, billed $400.20 a year. A connected account counts whether or not it spent, and a disconnected account frees its slot.

The counting rules overlap. Both count 10 Google Business Profile locations as 1 account and a GA4 property as 1 account. For a Google Ads manager account, both count the client accounts under it, not the manager account itself.

Where Windsor.ai's flat plans cover more accounts

Windsor.ai counts data sources, the platforms data comes from, and one account total, such as one ad account or one GA4 property. Basic covers 75 accounts across 3 data sources: $19 a month billed annually, $23 on monthly billing. Plus covers 200 accounts across 10 data sources: $249 billed annually, $299 monthly. Each platform counts once for all your clients, and plans are sized by sources and accounts, not by data volume.

The limit is the step between plans. A fourth data source moves Basic up to Standard, $99 a month billed annually or $118 monthly, and a 76th account moves it up to Plus. Porter Metrics adds each account at its tier rate instead.

The two cross over on monthly billing. Porter lists a flat $100 for 13 to 20 accounts, so up to 20 accounts on four or more platforms cost less there than Windsor.ai Standard at $118. From 21 to 39 accounts Porter lists $5 an account, while Windsor.ai Basic is $23 for up to 75 accounts on three platforms. Windsor.ai pricing lists every plan.

Destinations, refresh and AI chats

Porter Metrics lists Looker Studio, Google Sheets, Power BI and BigQuery as destinations, and says its MCP for Claude and ChatGPT is in every plan, the free plan included. It says its BigQuery scheduling runs at any rate on any plan.
