Best Looker Studio Connectors for Agencies and Freelancers

Your agency has three clients running Meta Ads, LinkedIn Ads, TikTok Ads, Pinterest Ads, and Microsoft Ads. You want their numbers in Looker Studio before the next reporting call. Several connector providers support those platforms—but their entry plans count sources, accounts, and destinations differently.

The best Looker Studio connector is the one that covers your reporting fields, fits your client portfolio, and delivers data on the schedule you need. Start with Google's native connectors where they cover the job. For other sources, compare a shortlist using the same accounts and the same report.

This guide compares Catchr, Supermetrics, Windsor.ai, Porter Metrics, Coupler.io, and Funnel, then gives you a practical checklist for testing your choice.

A note on naming: Google renamed Looker Studio back to Data Studio in April 2026. We use “Looker Studio” here to match the name many readers search for. Both names refer to the same reporting product in this guide. Google's naming update.

Which Looker Studio connector should you choose?

Use this table to decide which options deserve a trial. The provider sections explain the tradeoffs behind each recommendation.

These are starting points, not exclusive categories. More than one provider may fit your workflow.

Start with the sources your reports actually need

Before comparing subscriptions, list the platforms, accounts, and fields behind your reports.

A platform is a service such as Meta Ads. An account is the individual ad account you connect within that platform. A provider supplies the connectors. Vendors sometimes use “source” differently, so read their account definitions before calculating costs.

In our illustrative agency setup, three clients each have one account on five advertising platforms:

3 clients × 5 accounts per client = 15 connected accounts across 5 platforms.

That distinction matters. A provider may list all five platforms in its catalog while its entry plan only lets you connect three. Check both the source allowance and the account allowance.

Next, write down the fields your reports need. “Meta Ads supported” does not answer whether you can report the conversion action, creative detail, or campaign breakdown your client expects. Pick one representative report and turn its charts into a list of required metrics and dimensions.

When free native connectors are enough

If your reports use GA4, Google Ads, Search Console, and Google Sheets, evaluate the native options first. Google's connector catalog also includes databases such as PostgreSQL and MySQL; native connectors are not limited to Google-owned data sources. Google's connector catalog.

Avoid buying a partner subscription just to duplicate a connection that already meets your needs. Equally, a free connector does not make the underlying infrastructure free: BigQuery queries, for example, can generate separate charges. Google's guidance on freshness and query costs.

The best Looker Studio connector providers to compare

Catchr: for agencies working across reports, spreadsheets, and AI

Catchr is worth evaluating when client dashboards are one part of a broader marketing workflow. Its reporting plans include visualization and spreadsheet destinations, AI assistants, and unlimited users and requests. Starter covers three platforms and ten accounts; Momentum raises those allowances to five platforms and thirty accounts. Catchr pricing.

For Looker Studio, Catchr responds to data requests when a report opens or refreshes. That query-based workflow is distinct from a scheduled export. Catchr's Looker Studio connectors.

Check before choosing: count every selected client account and verify the exact fields in your report. In our five-platform example, Momentum is the first published plan with sufficient source and account capacity. Catchr's entry plan would be too small.

Supermetrics: for an established workflow or a specific source requirement

Supermetrics deserves a place on your shortlist if your team already uses its connectors and templates, or you need a particular integration it supports. Its Looker Studio offering includes reporting templates and automated updates. Supermetrics for Looker Studio.

Its Growth package lists seven sources, seven accounts per source, two users, and one core destination. Looker Studio is one of those destination options. Additional capacity is available through extras. Supermetrics pricing.

Check before choosing: calculate accounts within each source. Ten Meta Ads accounts exceed a seven-account allowance even if your other platforms have unused capacity. Price additional destinations and users if colleagues also need to work in the subscription. For a closer comparison, see Supermetrics vs. Catchr.

Windsor.ai: for many accounts on a few platforms

Windsor.ai is a useful budget candidate when your agency repeats the same platform mix across clients. Basic includes three sources, seventy-five total accounts, and unlimited users. Its pricing page also lists a free plan that reduces to one source and one account after the trial. Windsor.ai pricing.

Check before choosing: account capacity and source capacity grow separately. Basic has enough account capacity for our example, but its three-source limit cannot cover the five-platform mix. Standard is the first published tier that covers it.

Also check freshness against your reporting routine. Windsor's pricing FAQ describes a six-hour cache and a manual cache-clearing option. Do not assume that reopening a dashboard always retrieves new platform data. Windsor's refresh FAQ.

Porter Metrics: for pricing around connected accounts

Porter Metrics is worth evaluating when you prefer to size reporting around the number of connected accounts. Its reporting configurator changes the total as you add accounts, so multiplying the single-account price by your portfolio size can misstate the cost. Porter Metrics pricing.

Its catalog includes Meta Ads, LinkedIn Ads, and TikTok Ads. Confirm refresh behavior for your source during the trial: its public destination page describes scheduled updates and caching, while its help center describes direct API queries for paid media. Porter connectors, Data Studio integration, refresh guidance.

Check before choosing: use the reporting configurator for your exact account count and billing period. Verify that the update frequency and history available for your sources meet the report's requirements.

Coupler.io: for preparing data before reporting

Coupler.io is a candidate when you want to gather and transform data before sending it to Looker Studio. Its integration workflow includes connecting apps, previewing data, selecting the destination, and scheduling updates. Coupler.io's Data Studio integrations.

Active includes fifteen accounts, three destinations, unlimited users, and daily refreshes. Pro increases capacity to fifty accounts and adds hourly refreshes and team and client workspaces. Coupler.io pricing.

Check before choosing: account capacity alone may not determine the right plan. An agency that needs separate client workspaces or hourly updates should evaluate Pro even if its account count fits Active. Ask whether an agency package changes the price for your setup.

Funnel: for storing and standardizing agency data

Funnel is worth evaluating when the work extends to maintaining a shared marketing dataset before visualization. Agency Standard includes storage, data harmonization, and unlimited users and workspaces. The advertised starting price is $300 per month with annual billing. Funnel agency pricing.

Its capacity model uses flexpoints allocated to connectors, accounts, and destinations. The advertised starting price alone does not establish the cost of a particular client portfolio. Funnel's capacity model.

Check before choosing: request a quote for the actual connectors, accounts, destination, and reporting configuration. Evaluate whether the data preparation and storage solve a recurring problem for your team. Those capabilities should have a clear purpose in the workflow you are buying.

Compare the cost of your client setup

Here are two illustrative setups for an agency reporting across five paid media platforms: Meta Ads, LinkedIn Ads, TikTok Ads, Pinterest Ads, and Microsoft Ads. Each client has one account on every platform, and the agency uses one provider to bring those accounts into Looker Studio.

• Three clients: 5 platforms and 15 total accounts.
• Six clients: the same 5 platforms and 30 total accounts.

These cases show where Catchr's platform and account allowances offer a price advantage. They represent agencies with a broad paid media mix; they do not establish the cheapest provider for every possible setup.

The table compares annual billing. Monthly equivalents are annual totals divided by twelve, not month-to-month offers. Prices retain the vendor's published currency. Taxes, negotiated discounts, and unpriced extras are excluded. This is a single-provider comparison; it does not price splitting the portfolio across multiple subscriptions or providers.

Catchr has the lowest verified USD subscription total in both examples. At three clients, it costs $206 less per year than Porter and $398 less than either Windsor Standard or Coupler Active. At six clients, the annual difference is $711.20 versus Porter, $398 versus Windsor, and $1,598 versus Coupler Pro. Those differences are calculated from the linked annual prices.

Supermetrics is shown in EUR because that is the currency displayed on its pricing page; no exchange-rate conversion is included. Growth is a published package with enough capacity, but its configurable extras mean it is not a verified minimum quote. Funnel's advertised annual starting price is above Catchr's, while its final scenario price still requires confirmation.

These packages include different features. Coupler Pro includes hourly updates and client workspaces, for example, while Funnel includes storage and data harmonization. Compare those capabilities if your workflow needs them. The prices above establish a subscription-cost advantage for Catchr on the stated USD configurations, not feature equivalence or a universal price guarantee.

For this agency, growing from three to six clients keeps the Catchr subscription at $790 per year. Recalculate when you add a sixth platform or exceed thirty accounts: that changes the capacity you need.

Test a connector on one real client report

A pricing comparison can narrow your options. It cannot tell you whether the connector will reproduce the report your client needs. Test your two strongest candidates against the same report before migrating the rest of the agency.

1. Define what the report must reproduce

Choose a representative client and list the essentials: platforms, accounts, date range, campaign breakdowns, conversion actions, and who needs to view the report. Include one awkward requirement you already encounter, such as a specific conversion metric or an older comparison period.

Set the pass criteria before starting. For example: “We can reproduce last month's campaign spend and the agreed lead metric, then share the report with the account manager.” This is a test requirement, not a promise from the provider.

2. Compare the numbers under the same conditions

Use a closed reporting period. Match the source account, currency, time zone, attribution settings, and filters before comparing totals. Record the platform's value and the connector's value for the same metric.

Investigate differences before treating them as connector failures. A report using a different conversion definition is answering a different question. Ask the provider to explain any discrepancy you cannot resolve, and keep the answer with your test notes.

3. Check freshness through the whole workflow

There are several moments to distinguish: when the advertising platform makes data available, when the provider retrieves it, and when the report requests or reuses it. Google's reporting layer can serve previously queried results from memory, and community connector freshness varies. How Data Studio freshness works.

Test the refresh action you will actually use before a client call. Also change the date range and campaign filter. Write down what changed and when, rather than recording “real time” as a yes-or-no feature.

4. Test the handoff to a colleague or client

Open the report using a representative viewer account with the intended permissions. Confirm that the right data is visible and that access is appropriately limited. Test on a duplicate or trial report so the exercise does not interrupt a live client dashboard.

Document who owns the connection and how to reconnect it if authorization expires. That handoff matters when the person who created the report is away.

5. Keep a decision sheet

Use the same checklist for each candidate. Fill it with observed results, not vendor promises.

If a candidate fails an essential requirement, ask whether a configuration change resolves it and what that change costs. Record the answer before committing to a longer billing term.

Build your first client report with the right connector

Start with the sources and fields you need, price the full account count, and run one representative report through your shortlist. Keep the test small enough to complete and realistic enough to expose the problems you handle every month.

If Catchr fits that workflow, explore its Looker Studio connectors and use the 14-day trial to validate a client report. The trial does not require a credit card. Catchr trial details.

You can start from a Catchr reporting template or follow the guide to creating a data source. A free template gives you a report layout; check the separate subscription requirements for the data connections it uses.
