Windsor.ai pricing

We support Power BI, Looker Studio, Google Sheets, Excel, BigQuery, Snowflake, Tableau, PostgreSQL, MySQL, Python, Amazon S3, Azure Blob Storage, Azure SQL, Redshift, and Databricks.

A scheduled sync allows you to sync data from Windsor.ai to your preferred database, file storage or Google Sheets. We currently support Google Sheets, BigQuery, Snowflake, Amazon S3, Amazon Redshift, Azure SQL, Azure Blob Storage, PostgreSQL, MySQL, and Databricks.

On the Basic and Standard plans, you can set up a maximum of 5 concurrent scheduled syncs, where each sync corresponds to one table updated once per day. Additionally, on the Basic plan and above, you can perform backfills to load historical data into your table. Note that on the Basic plan, each backfill also counts as a scheduled sync.

Windsor.ai uses volume-based pricing for data warehouse and database destinations. This means your monthly plan includes a fixed number of data rows that can be transferred to specific destinations. Once you exceed that limit, additional usage is billed per 1 million MAR (monthly active rows), at the rate specified by your plan.

The following destinations are subject to data volume limits:

• Google BigQuery
• Snowflake
• Databricks
• Amazon S3
• Azure SQL
• MySQL
• PostgreSQL

A “row” refers to a single data record transferred from a source to a supported destination (e.g., a row inserted into BigQuery). We count the number of rows synced during each data refresh and total that for the billing cycle.

You can view your current monthly row usage in your Windsor dashboard on the plan details and limits card.

Yes. If you reach your monthly MAR limit for data warehouse or database destinations, you can purchase additional volume as an add-on — no need to upgrade your entire plan. Add-ons are flexible and available in different quantities, so you can buy exactly what you need, when you need it.

You can send an authorization link to external users (e.g., teammates or clients) so they can connect a data source under your account, without sharing credentials.

Yes, Windsor.ai provides an absolutely free 30-day trial so you can explore the platform’s core features with the following conditions:

• 1 user, 1 data source, 1 account, and 5 destinations
• 30-day history limit
• No hidden fees or premium connectors—you can try all data sources and destinations

Yes, we can add this upon request. To get started, add it to our feature requests board, and we’ll plan and deploy it as soon as possible.

For immediate custom connector development without a queue, consider our Enterprise plan.

Yes. You can upgrade or downgrade your plan at any time, and we’ll automatically apply prorated billing so you only pay for what you actually use.

If you upgrade mid-cycle:

You’ll be charged only for the remaining time on the higher plan, minus a credit for the unused time on your current plan.

Example:

You’re on the $23/month plan.

On June 16 (midway through your billing cycle), you upgrade to the $118/month plan.

Here’s what happens:

• You get a $11.50 credit for the unused half of the $23 plan.
• You’re charged $59.00 for the remaining half of the $118 plan.
• Total due immediately: $47.50

On your next billing date (July 1), you’ll be billed the full $118 for the new plan.

If you downgrade mid-cycle:

Your current plan remains active until the end of your billing cycle. The downgrade takes effect at the start of the next cycle, and your new (lower) rate will be charged then — no immediate charge or credit.

When you subscribe for a monthly plan, you’re billed for the upcoming 30-day period. Windsor.ai subscriptions are recurring by default. If you don’t cancel your subscription, it continues to renew each billing cycle, even if you’re not actively using the platform. This is standard for monthly SaaS plans.

So, for example, if your last payment was 1 year ago and you only paid again today, that means your subscription was technically active but unpaid for 12 months. To continue using the platform under the same account, you may need to cover the unpaid months or create a new subscription.

At this time, we do not offer a “pause” option. You can cancel your subscription anytime and reactivate it later when needed. If you do not cancel, billing will continue automatically each month, so you’ll need to cover the unpaid months.

We take data security very seriously. Windsor.ai is GDPR compliant and SOC2 Type 2 certified. Our servers are hosted in a world-class data center in Germany.

You can purchase a subscription using most credit cards such as Visa, Mastercard or American Express (we use Stripe for payment processing).

Please note that manual invoicing and custom vendor onboarding processes are only available for Enterprise plans.

If your payment fails, our system will automatically retry up to 8 times over the course of 7 days using a smart recovery process.
