What Windsor.ai is
Windsor.ai is a no-code ELT/ETL service for transferring data between sources and destinations. Its connectors cover more than 350 sources and can schedule syncs, match schemas, and load incremental updates. Listed sources include Google Ads, Google Analytics 4, HubSpot, Salesforce, Shopify, TikTok Ads, and Facebook Ads. Destinations include BI tools, spreadsheets, databases, and warehouses such as Power BI, Looker Studio, Google Sheets, Excel, BigQuery, Snowflake, Tableau, PostgreSQL, and MySQL. Windsor MCP links Windsor.ai data to AI tools including ChatGPT, Claude, and Copilot for analysis. The service is available on the web and through an API, with use cases described for analysts, agencies, and data teams. A free plan and a 30-day trial are listed.

Windsor.ai is a no-code service for moving data from business and advertising platforms into analytics, spreadsheets, databases, warehouses and AI tools. It is best suited to analysts, agencies and data teams building recurring reports or managed pipelines. Its broad connector range is useful, but the free tier’s severe source and account limits make it a poor fit for a multi-platform workflow.
Overview
Windsor.ai connects more than 350 sources—including Google Ads, Google Analytics 4, HubSpot, Salesforce, Shopify, TikTok Ads and Facebook Ads—to destinations such as Power BI, Looker Studio, Google Sheets, Excel, BigQuery, Snowflake, Tableau, PostgreSQL, MySQL, Python and Windsor MCP. Bringing these connections together can simplify reporting across tools, though plan quotas determine how much of that breadth a team can actually use.
Scheduled syncs, schema matching and incremental loading support repeatable data transfers. Windsor MCP also connects Windsor.ai data with ChatGPT, Claude and Copilot for analysis. The company was founded in Zurich in 2017 and is headquartered in Baar, Switzerland.
Key features
Data transfer and scheduling
Incremental loading and scheduled syncs are practical for recurring pipelines because they move data in a managed cadence rather than requiring a fresh manual export each time. Schema matching can help align data with destination structures. The cadence varies by plan: Basic is daily, Standard and Plus allow daily or hourly syncs, and Professional adds 15-minute syncs. That makes the higher tiers more suitable for time-sensitive reporting; daily updates may be enough for routine dashboards.
AI analysis
Windsor MCP extends the connection layer to ChatGPT, Claude and Copilot. This is relevant to teams that want to analyze connected data through those tools, although it does not replace the need to select a plan with enough sources, accounts and destination tasks for the underlying pipeline.
Security and support
Windsor Group AG says it completed a SOC 2 Type II audit and processes personal data in compliance with UK GDPR and EU GDPR. Customer data is encrypted in transit and at rest, with role-based access controls and separate customer data trust zones. Connector memory is retained for up to 24 hours; disk cache is deleted after at least 20 days without access, with a maximum retention period of about three weeks. All plans include live chat, alongside documentation, ticket submission, a community portal and YouTube resources.
Pricing
Windsor.ai has a lasting free plan, a 30-day free trial and paid plans. The pricing note quotes paid access from $19/mo (annual), while the plan prices below are billed monthly; compare the stated term with your billing preference before choosing.
| Plan | Price | Included limits and syncs |
|---|---|---|
| Forever Free | free | 1 user, 1 data source and 1 account |
| Free (30-day trial) | free | 1 user, 10 data sources, 15 accounts, 5 destination tasks and 30-day history |
| Basic | $23 a month, billed monthly | Unlimited users, 3 data sources, 75 accounts, 5 destination tasks and daily syncs |
| Standard | $118 a month, billed monthly | Unlimited users, 7 data sources, 75 accounts, unlimited destination tasks and daily or hourly syncs |
| Plus | $299 a month, billed monthly | Everything in Standard, with 10 data sources and 200 accounts |
| Professional | $598 a month, billed monthly | Everything in Plus, with 14 data sources, 500 accounts, auto-add accounts and daily, hourly or 15-minute syncs |
Forever Free is suitable for a single-user, single-source trial of an ongoing setup, but it does not include scheduled sync backfills after the 30-day trial period. The trial has much more room for evaluation—10 sources and 15 accounts—but expires after 30 days. Basic adds unlimited users and daily scheduling, yet its three-source and five-task caps constrain broader reporting. Standard is the first tier with unlimited destination tasks and hourly syncs; Plus raises source and account capacity, while Professional is for larger pipelines that need more accounts and 15-minute updates.
The pricing FAQ sets API limits at 600 requests per minute and 10,000 per day. Review those ceilings alongside the source and account quotas if your integration relies on the API.
Platforms
Windsor.ai is available on web and through an API. Its connector options span BI, spreadsheet, database, warehouse, Python and AI destinations, but the number of sources, accounts, tasks and syncs depends on the plan.
Who it's for
Analysts can use Windsor.ai to consolidate data for reporting, while agencies can build client dashboards and data teams can manage recurring pipelines. It is a stronger fit when the time saved by connecting multiple sources and destinations outweighs the cost and quota planning. A single user with one source may find Forever Free sufficient; teams with several sources should assess paid-tier capacity before committing.
Pros and cons
- Pro: More than 350 sources and a wide range of destinations can reduce the need to stitch together separate data connections.
- Pro: Incremental loading and plan-based scheduling support recurring reporting, with 15-minute syncs available on Professional.
- Pro: All plans include live chat, and the company describes encryption, role-based access controls and separate customer data trust zones.
- Con: Forever Free permits only one source and one account, and scheduled sync backfills are unavailable after the trial.
- Con: Paid plans impose source and account quotas, and hourly or 15-minute syncs require higher-priced tiers.
- Con: The $19/mo starting price is quoted for annual billing, while the listed paid plan prices are monthly; compare terms carefully.

Triple Whale may suit a team prioritizing unlimited users and 12 months of data storage on its free plan. Choose Mailmunch if forms, popups, landing pages and a welcome email are the priority, with basic analytics included on its free plan. SegmentFlow.ai is an option for email sending, with a free plan capped at 2,500 emails per month and a $19 monthly Starter tier for 10,000 emails. Advanza may fit someone seeking an AI-created campaign, newsletters, one social account and basic reporting on a free plan. Amazon Marketing Cloud is a free option for eligible advertisers.

Bluey Email is another freemium option with a free allowance of 500 emails and 500 contacts per month.
Verdict
Choose Windsor.ai if you need to move data across several business sources into reporting, storage or AI destinations with scheduled, incremental transfers. Its connector breadth and higher-tier cadence options are the main reasons to consider it; its narrow free tier and escalating source, account and sync limits are the reasons to look elsewhere if your pipeline is small or your budget depends on a roomy free plan.
Verdict
Windsor.ai connects a large range of data sources to analytics, storage, spreadsheet, and AI destinations, with scheduled and incremental transfer options. The lasting free tier is tightly limited, so review source, account, and sync needs before choosing a plan.
