#1
Porter Metrics Cheapest entry
3.8

Solo costs $14.99 a month for one connected account, and the free plan covers 3 accounts with every destination and feature, no expiration date. Connector count tops out around 50, and data arrives as raw API fields instead of pre-built metrics.

Best for: Solo marketers and small agencies who need a handful of ad accounts flowing into Looker Studio without paying for 300 connectors they'll never use · from $14.99/mo

#2
Windsor.ai Flat pricing, unlimited users
3.9

Basic runs $23 a month for 3 sources with unlimited users and the full connector catalogue included, no per-seat or premium-connector upcharge. Hourly refresh needs the $118 Standard tier, and G2 reviewers ask for a mid-tier between the two.

Best for: Growing teams and small agencies who want one predictable monthly price across sources and seats, plus built-in attribution modeling instead of a bolt-on tool · from $23/mo

#3
Coupler.io Best free plan
3.9

The free plan moves one real account into one destination with no expiration date, rare for a free tier in this category. Starter runs $32 a month for 3 accounts once you need daily refresh, and extra accounts cost $5.99 a month each after that.

Best for: Small teams and agencies that want to test a real connector for free before paying, then scale reporting without a per-seat bill · from $32/mo

#4
Supermetrics Most connectors
4.4

Starter runs €49 a month for 3 sources, 1 destination and 1 user, backed by a connector list past 300, the deepest of the seven. Sources, users and destinations each bill as a separate line item, so the invoice grows with every platform, seat or destination you add.

Best for: Agencies and in-house teams pulling data from many ad and marketing platforms into Looker Studio, Sheets, Excel or a warehouse · from €49/mo

#5
Power My Analytics Budget 5-source stack
4.0

Business costs $49.95 a month billed annually for 5 live sources, 5 accounts and 2 admin seats, well under a comparable source count on Supermetrics or Funnel.io. The free plan only shows sample data, so real testing needs the 14-day trial instead.

Best for: Small teams and freelancers who need a handful of live ad accounts on a dashboard without paying Supermetrics-tier prices · from $49.95/mo

#6
Funnel.io Enterprise warehouse feed
3.8

Starter costs $300 a month for 121 connectors but ships zero export destinations, so the Looker Studio feed only turns on at the $600-a-month Business tier. Flexpoints usage billing meters everything past the tier limit, and invoices often land closer to four figures a month.

Best for: Marketing teams and agencies managing dozens of ad accounts who need a governed data warehouse feed, not just a dashboard connector · from $300/mo

#7
Dataslayer Best permanent free tier
4.0

A free plan for 1 connector and 1 user that never expires, then Starter at €29 a month for 3 connectors with daily refresh. AI-assisted queries start on the €99 Advanced tier, and the connector list runs to 60-plus sources.

Best for: Small marketing teams and agencies whose sources are mostly mainstream ad and analytics platforms, who want AI-assisted queries without Supermetrics-level per-source pricing · from €29/mo

Which Looker Studio connector to pick

All seven tools move ad, analytics or CRM data into Looker Studio on a schedule. Entry price ranges from $14.99 a month to $300, and the table below shows what each tier buys and who it fits.

Porter Metrics prices by connected account, not by seat, which is why it undercuts everything else here for a one- or two-account stack. Solo costs $14.99 a month for one account, Teams scales to $39.99 for up to five, and every tier ships all four destinations with unlimited users. G2 reviewers rate it 4.6 out of 5 across 189-plus reviews, citing fast setup and direct founder access. Coverage is the tradeoff: around 50 connectors, and the data arrives as raw API fields, not calculated metrics. Full review.

Windsor.ai charges by source count, not by seat, and unlimited users ship even on the $23-a-month Basic tier, alongside the full connector and destination catalogue. It also bundles multi-touch attribution modeling, first-click, last-click, linear, Markov and algorithmic, into every plan instead of selling it as an add-on. Basic’s 3 sources jump straight to Standard’s 7 at $118, nothing priced in between, a recurring complaint in G2 reviews. Full review.

Coupler.io’s free plan moves real data, not a sample dashboard: one account into one destination, no expiration date, enough to confirm a connector maps the right fields before anyone pays. Starter runs $32 a month for 3 accounts with daily refresh, and the same sync can land in a spreadsheet, Looker Studio and a warehouse at once. Every account past a tier’s bundled limit adds $5.99 a month, the detail that changes the math for a long client roster. Full review.

Supermetrics still lists the deepest connector catalogue here, more than 300 sources spanning paid media, organic social, SEO tools, ecommerce, CRM data and affiliate networks. Starter runs €49 a month for 3 sources, 1 destination and 1 user; each bills as its own line item, so the invoice grows with every added platform, seat or destination. Long-time customers report their bill doubling to tripling within a couple of years. Full review.

Power My Analytics competes for the same small-stack buyer as Porter Metrics. Business costs $49.95 a month billed annually for 5 live sources, 5 accounts and 2 admin seats, with extra accounts at $14.95 and extra admins at $4.95. G2 and Capterra reviewers call it a cheaper substitute for Supermetrics, but the free plan only shows sample data, so real testing needs the 14-day trial. Full review.

Funnel.io is built for a buyer who has outgrown a dashboard connector. Starter costs $300 a month for 121 connectors but ships no export destinations, only Funnel’s own dashboards and spreadsheet exports. The Looker Studio feed that matters here switches on at Business, $600 a month, which adds 579 connectors and 26 destinations including BigQuery, Snowflake and Tableau. Flexpoints, Funnel’s usage-based billing on top of either tier, draws the most complaints in reviews, and invoices often land closer to four figures a month. Full review.

Dataslayer is the newest addition, checked in October 2026. Its free plan never expires and covers 1 connector and 1 user, Starter runs €29 a month for 3 connectors with daily refresh, and Advanced at €99 adds hourly refresh, data blending and AI-assisted queries. The trade-off is reach: 60-plus connectors against several hundred at Supermetrics or Windsor.ai. Full review.

What three sources into Looker Studio really cost

Advertised entry prices don’t show what three real sources cost once a stack needs more than the cheapest tier covers.

ToolTierPrice for ~3 sourcesWhy
Porter MetricsTeams$39.99/moSolo covers only 1 account; Teams covers up to 5
Windsor.aiBasic$23/moCovers 3 sources, unlimited users
Coupler.ioStarter$32/moCovers 3 accounts, 1 destination
SupermetricsStarter€49/mo3 sources, 1 destination, 1 user
DataslayerStarter€29/moCovers 3 connectors, daily refresh
Power My AnalyticsBusiness$49.95/moSmallest paid tier; covers up to 5
Funnel.ioBusiness$600/moStarter ($300) has no export destination

Windsor.ai ($23), Dataslayer (€29) and Coupler.io ($32) are the cheapest ways into three sources, figures taken straight from the vendors’ pricing pages (Dataslayer checked in October 2026, the rest in July 2026). Porter Metrics costs $39.99 once the stack needs a paid tier for more than one account, and Funnel.io’s $600 is the entry cost of reaching any export destination, since Starter’s $300 tier has nowhere to send data.

Free ways to test a connector first

Six of the seven connectors let you try before you pay, though “free” means different things depending on the vendor.

  • Coupler.io’s free plan never expires: one account, one destination, 100 rows per run, manual refresh only.
  • Porter Metrics’ free plan covers 3 accounts with every destination and feature, a 30-day lookback cap, no expiration date.
  • Windsor.ai’s 30-day trial unlocks 10 sources and 15 accounts, then drops to a permanent Forever Free tier capped at 1 source and 1 user.
  • Dataslayer’s free plan never expires: 1 connector and 1 user, plus a 15-day trial with no card that opens more before the account drops back to Free.
  • Supermetrics has no free plan, but every connector and destination gets a 14-day trial, no card required.
  • Power My Analytics’ free plan only shows sample numbers, not your accounts. The 14-day trial, no card required, is the way to see your own data.

Looker Studio is one destination among several these seven tools support; most also feed spreadsheets, warehouses or Power BI. For the full field, see our marketing reporting connector roundup.

Frequently asked questions

Does Looker Studio have free native connectors?

Yes. Google's own sources, GA4, Google Ads, Search Console, BigQuery and Sheets, are free native connectors. Third-party sources such as Meta Ads, LinkedIn Ads or a CRM need a partner connector like the ones on this page.

Which Looker Studio connector is cheapest for Facebook Ads?

Porter Metrics' Solo plan, $14.99 a month for one account, is the cheapest entry point for a single Facebook Ads account. Add two more sources and Windsor.ai's Basic tier covers all three for $23 with unlimited users included.

Can one connector feed Looker Studio and Google Sheets at the same time?

Yes. Coupler.io can push one source into a spreadsheet, Looker Studio and a warehouse at once, and Windsor.ai includes every destination, Looker Studio and Sheets among them, on every tier including Basic. Supermetrics feeds both too, but a second destination costs extra.
