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.
Who Windsor.ai is for
- Fits if you want a low-priced feed into Looker Studio
- Works for agencies that connect many client accounts through a shared sign-in link
Who Windsor.ai is not for
- Tight if you stay free: after 30 days it is 1 source, 1 account and 30 days of history
- 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
Why Windsor.ai gets a 2.4
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- BValue for money$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.
- CFree plan and trialA 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.
- CFeatures350+ 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.
- CEase of useNo store rating on record. Picking sources, authorising accounts and setting up destination tasks is setup work.
- BPlatforms and integrationsWeb only, with Looker Studio, Power BI, Google Sheets, databases and an MCP for AI assistants. No desktop or phone app.

Keep Windsor.ai, or make your own?
Keep it
The plain part of Windsor.ai you could make: reports. What surrounds it you could not. The 3 things listed below take a company, not a weekend.
It is one of the better ones too: its GPA of 2.4 is higher than 27 of the 40 other marketing reporting and call tracking tools we grade. It costs $228 a year.
What you could make
- Reports: an app builder makes this well.
What you could not
- Connections that pull numbers from dozens of other services.
- It plugs into other products, Looker Studio, Power BI and Google Sheets among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Windsor.ai’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
