The report card
Best for cheap connectors into Looker Studio and Sheets
Windsor.ai moves data from 350+ sources into Looker Studio, Power BI, Sheets and databases, with an AI hookup through its MCP. Paid plans start at $19 a month, but that tier stops at 3 data sources and 75 accounts, and the free plan shrinks to 1 source and 1 account once the 30-day trial ends.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | $19 a month on yearly billing, inside the category's cheaper quarter, which starts at $30. That Basic plan has 3 data sources and daily sync; Standard is $99. |
| Free plan and trial | C | A 30-day trial with 10 sources, then a Free plan of 1 user, 1 data source, 1 account and 30 days of history. You'll hit that cap quickly. |
| Features | C | 350+ sources, unlimited Looker Studio and Power BI syncs and MCP access. But Tableau goes through Sheets or a database, and daily sync is all Basic offers. |
| Ease of use | C | No store rating on record. Picking sources, authorising accounts and setting up destination tasks is setup work. |
| Platforms and integrations | B | Web only, with Looker Studio, Power BI, Google Sheets, databases and an MCP for AI assistants. No desktop or phone app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Windsor.ai is for

- Skip it if you need Tableau directly, as it reaches it through Sheets or a database
- Pricey if you outgrow Basic: Standard is $99, Plus $249 and Professional $499 a month on yearly billing
- Watch out: SSO and white-labeling are Enterprise only and need a quote
