Windsor.ai alternative: pricing, connectors, and Windsor.ai vs Supermetrics compared

How much does Windsor.ai cost?

Windsor.ai publishes its whole ladder, which is more than most of this category manages. On annual billing it runs $19 a month for Basic (3 data sources, 75 accounts), $99 for Standard (7 sources), $249 for Plus (10 sources, 200 accounts), and $499 for Professional (14 sources, 500 accounts, 15-minute syncs). Paid monthly those become $23, $118, $299, and $598. Enterprise is quoted and stretches to 200 sources and 50,000 accounts.

There is also a real free tier. The 30-day trial gives you 1 user, 10 data sources, 15 accounts, and 5 destination tasks with 30 days of history, and when that lapses the forever-free plan keeps 1 user, 1 data source, and 1 account. Every paid plan includes unlimited users and access to all sources and destinations, which is the genuinely differentiated part of the pricing: no premium-connector surcharge and no per-seat fee.

The number to plan around is the data source count, because that is the meter. A team running Google Ads, Meta, TikTok, GA4, Search Console, Shopify, and Stripe is already at seven sources, which is the Standard plan at $99 a month. Add Klaviyo and LinkedIn and you are into Plus at $249. Compare that against a flat rate before assuming the $19 headline applies to you.

Windsor.ai vs Supermetrics: which is better?

They do the same job with opposite pricing philosophies. Both are no-code marketing ETL: pull from ad platforms and analytics, push into Sheets, Looker Studio, Power BI, or a warehouse. Supermetrics is the older, deeper product with the most hardened connectors in the market and the better track record when an API changes overnight. Windsor.ai is the cheaper, flatter one, with a broader raw connector count and everything included.

Price is where the choice usually gets made. Supermetrics starts at EUR 39 a month on yearly billing and charges along three axes at once: which sources, which destinations, and how many seats. Windsor charges on one axis, sources, and throws in unlimited users and all destinations. For a small team the real-world gap is often larger than the list prices suggest, because the Supermetrics bill grows every time somebody new needs access.

Supermetrics earns its premium when reliability is the product. If a broken sync costs you a client report on a Monday morning, the maturity is worth paying for. Our Supermetrics alternative page covers that comparison in full, and Supermetrics vs Funnel.io works through the tier above both of them.

The question neither answers: both hand you rows. If what you actually wanted was to know whether last month was profitable, you are still going to build that view yourself in a third tool.

Is Windsor.ai a dashboard or a data pipeline?

A data pipeline, and it is upfront about that. Windsor.ai is an ELT and ETL tool whose output is a destination: Looker Studio, Google Sheets, BigQuery, Snowflake, Power BI, Tableau, or Excel. The dashboards you see in Windsor marketing material are Looker Studio templates fed by Windsor, not a native reporting product.

This matters for budgeting because the subscription is rarely the whole cost. Somebody has to design the report, define what each metric means, keep the definitions consistent as channels are added, and fix it when a platform renames a field. That work is invisible until the person who did it leaves. Teams that are honest about the hours usually find the pipeline is the cheap part.

If you have an analyst and a warehouse, this is a fine architecture and Windsor is a cheap way to feed it. If your team is three marketers and nobody owns SQL, buying pipes and hoping the dashboard appears is how you end up back in a spreadsheet. That is the case a finished marketing dashboard software product exists to serve.

What is the best Windsor.ai alternative?

It depends on which half of the problem you are solving. If you want the same job done, moving marketing data into your own BI tool or warehouse, Supermetrics is the more mature pipeline and Funnel.io is the heavier one for teams that need real transformation and governance, starting around $300 a month on annual billing. Improvado sits at the enterprise end with most of its tiers unpriced.

If you want reporting rather than plumbing, the comparison set changes entirely. DashThis at $44 to $429 a month is built for agencies sending recurring client reports. Looker Studio is free and is usually what Windsor feeds. And a blended dashboard replaces the pipeline plus the BI layer plus the maintenance with one flat $79 a month, at the cost of a narrower connector list.

The clarifying question is what you plan to do on the Monday after it is set up. If the answer is "write queries against fresh data", buy a pipeline. If the answer is "look at whether we made money last week", buy the dashboard. Our marketing reporting software pricing comparison lays out the whole field on verified numbers.

Does Windsor.ai calculate blended ROAS or blended CAC?

Not on its own. Windsor.ai delivers the ingredients, spend rows from each ad platform and revenue rows from your store or billing system, into whatever destination you chose. Turning that into blended ROAS means summing spend across every account, summing revenue actually collected, and dividing, then keeping that calculation correct forever. Blended CAC needs the same discipline plus an agreed definition of a new customer.

That is not difficult arithmetic, which is exactly why it gets built badly. The common failure is a Looker Studio blend that quietly double counts a channel after somebody adds a second Meta ad account, and nobody notices for a quarter because the number still looks plausible.

MixedMetrics computes those metrics as the product rather than as a report you assemble. Connect the accounts and blended ROAS, blended CAC, MER, LTV, and LTV:CAC populate with the definitions already fixed. If you want the reasoning behind them first, blended ROAS and blended CAC explain why the blended view is the one finance ends up trusting.

Is Windsor.ai good for agencies?

It can be, with a caveat that catches people out. Unlimited users on every paid plan is unusually generous, so seat count is not the constraint it is with Supermetrics. The constraint is data sources and accounts. Basic covers 75 accounts, Plus 200, Professional 500, so a fifteen-client agency running three channels each is well past the entry plan before it starts.

The bigger gap is that Windsor has no client-facing reporting layer. There is no white-label portal, no scheduled branded PDF, no client login, because those belong to the destination tool. Agencies typically end up paying for Windsor plus Looker Studio work, or buying a purpose-built agency reporting product instead.

For that workflow, DashThis, Swydo (one plan at EUR 69 a month monthly or EUR 62 annually, 10 sources included then tiered add-ons), and AgencyAnalytics are built for it and include white-labeling. We are not: MixedMetrics has no white-label client portal, which we would rather state plainly on a comparison page. Our marketing dashboard for agencies page explains where we do and do not fit that model.
