Windsor.ai vs Supermetrics: price, connectors, and AI assistants compared

Yes, for a solo marketer ($19 against €117, about $130) and for 10 sources sent to one destination ($249 against €246, about $274). The agency setup needs a Supermetrics Enterprise quote. Windsor.ai Basic costs $19/mo for 3 sources and any destination (5 destination tasks). Supermetrics Starter costs €39/mo (about $43) for 2 sources and 1 user. For 10 sources, the comparison is Windsor.ai Plus against Supermetrics Growth with 3 extra sources. Dollar amounts use the ECB rate of 27 October 2026.

If you already pay for Supermetrics Growth and report only in Sheets, staying costs about $25 a month more than Windsor.ai Plus for 10 sources, with no migration work. Supermetrics also has a much larger G2 review base (820+ reviews against Windsor.ai’s 90). Supermetrics’ Business Context feature saves reporting rules, such as a fixed reporting currency, and Claude or ChatGPT applies them in every chat. Supermetrics’ write actions also come with two safeguards: changes go to a changelog, and you turn write access on for each ad platform.

Yes. Claude, ChatGPT, and Copilot are core destinations on every Supermetrics plan. On Starter and Growth, an AI assistant uses your one included destination. A second destination, such as Data Studio or Sheets, costs extra. On Windsor.ai Basic ($19/mo), Claude, Data Studio, and Sheets share one plan.

Yes. Windsor.ai is listed natively in Claude’s connector directory and ChatGPT’s plugin directory, so you add it in one click. It also works with Copilot and Gemini Enterprise. On 19 platforms, including Meta Ads, Google Ads, TikTok Ads, LinkedIn Ads, and Microsoft Ads, the assistant can also make changes for you. See the full list of write actions.

Supermetrics lists 39 premium sources on Enterprise only, including Salesforce, DV360, Campaign Manager 360, Search Ads 360, Google Ad Manager, Criteo, X Ads, and The Trade Desk.

Yes, on Windsor.ai. Warehouses such as BigQuery and Snowflake are on every plan. After its first 30 days, the free forever plan covers 1 source and 1 account. For more warehouse syncs or backfills, paid plans start at $19/mo. On Supermetrics, data warehousing is an Enterprise feature.

No. Windsor.ai has no fixed schema catalog. Instead, you describe what you need to Claude or ChatGPT with Windsor.ai connected: the platform, the fields, and how you will query the table. The assistant drafts the columns, partitioning, and clustering. You review the design and apply it in the Windsor.ai dashboard in a couple of clicks.

Connect the same data sources in Windsor.ai, then ask Claude or ChatGPT, with Windsor.ai connected, to copy or improve your existing table design. You can start with prompts like these.

I'm moving my Meta Ads reporting from Supermetrics to Windsor.ai. My old BigQuery table was partitioned by day and clustered by campaign_id. Help me set up the same destination task in Windsor.ai: which fields to pull, and how to set partitioning and clustering to keep query costs down.

Design a BigQuery table for my Google Ads spend and conversions, refreshed daily, that I can filter fast by account and campaign. Which fields should I include, and what partitioning and clustering do you recommend?

I have five Supermetrics tables (Meta Ads, Google Ads, TikTok Ads, LinkedIn Ads, GA4) that I want to merge into one blended reporting table in Snowflake. Help me design the schema and pick the fields from each source so they join cleanly on date and account.

Here's the column list from my old Supermetrics BigQuery export: [paste column names]. Map these to the closest Windsor.ai fields and recommend a table structure for the same report.

Yes. First, add the Windsor.ai connector as a data source in Data Studio. Then make a copy of the report. In the copy dialog, replace each Supermetrics data source with the Windsor.ai data source you just added. Field names can differ between the two tools. Charts that use fields with different names need the field picked again.

Install the Windsor.ai Sheets add-on and recreate each query: pick the data source, accounts, fields, and schedule. Supermetrics queries do not import automatically. Start with the sheets your reports depend on.

Yes, for formulas on one source’s fields. Copy those formulas from Supermetrics and ask Claude, connected to Windsor.ai, to recreate them as Windsor.ai custom fields. Claude checks the field names on each connector and shows you every formula before it creates one. A Supermetrics formula that mixes fields from several sources won’t carry over, because a Windsor.ai custom field works on one connector’s fields. Rebuild those as calculated fields in your report or warehouse. See how to migrate custom fields with Claude.

Yes, as far back as each platform’s API allows. On paid plans, Windsor.ai reads history directly from each platform, so you import nothing from Supermetrics. History older than a platform’s API limit exists only in your old Supermetrics exports, so keep those.

Yes. Through the blended Windsor.ai connector, spend, clicks, and impressions from the ad platforms you connect come under the same field names, with a data source column. One table or chart can show Google Ads, Meta Ads, TikTok Ads, and LinkedIn Ads together.

Omnicom Media Group Hong Kong moved its pipeline for about 1,900 ad accounts on 11 platforms from Supermetrics to Windsor.ai. Windsor.ai now loads the data into BigQuery in under two hours. The team saves 40+ hours a week that went into manual CSV exports and script upkeep. Chris Kwok, Head of Data & Analytics, said: “Windsor.ai turned our tangled web of scripts into a single, dependable pipeline.” Read how Omnicom Media Group Hong Kong moved to Windsor.ai.

Windsor.ai, if your team needs more than 2 users or a warehouse. Every paid Windsor.ai plan has unlimited users at no extra cost, and Standard ($99/mo) covers 7 sources and 75 accounts in total with any destination. Supermetrics Growth (€159/mo, about $177 at the ECB rate of 27 October 2026) includes 2 users and 7 accounts per source, with up to 20 accounts per source through paid add-ons. If your clients connect their own accounts, Windsor.ai’s Enterprise plan offers white-labeling. The authorization links those clients use then carry the agency’s brand name and colors.

Yes. Windsor.ai has a free forever plan with no credit card. For the first 30 days, you can connect up to 10 sources and 15 accounts and run 5 destination tasks. After that, the free plan covers 1 user, 1 source, and 1 account, with every destination, warehouses included. Supermetrics has no free plan. It has a 14-day free trial.
