Seven Looker Studio connectors pull ad and analytics data into your reports, and the monthly bill ranges from $15 for a single account to $600 for a warehouse-grade feed. We priced all seven against their live pricing pages, checked in July and October 2026.
ToolsGavel's top pick: Supermetrics (4.4/5, from €49/mo) — 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.

Audited prices verified against live vendor pricing pages — full dataset in the Pricing Gap Index.
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
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
Business costs $41.63 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 $41.63/mo
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
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
Starter costs $300 a month for 117 connectors and includes Looker Studio among its 13 lightweight destinations; the warehouse-grade destinations (BigQuery, Snowflake) only unlock among Business's 46 destinations at $600 a month. 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
Costs $15 a month for one connected account ($12.50 billed annually), and the free plan now covers unlimited accounts with every destination and feature, no expiration date (AI-generated dashboards carry a watermark). 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 $12.50/mo
All seven tools move ad, analytics or CRM data into Looker Studio on a schedule. Entry price ranges from $15 a month to $300, and the table below shows what each tier buys and who it fits.
| Tool | Entry price | What the entry tier buys | Best for |
|---|---|---|---|
| Porter Metrics | From $15/mo ($12.50 annual) | 1 account, every destination, unlimited users | Solo marketers with 1-2 accounts |
| Windsor.ai | $23/mo | 3 sources, unlimited users, full catalogue | Teams that want one flat bill |
| Coupler.io | $32/mo | 3 accounts, 1 destination, daily refresh | Teams testing before they scale |
| Supermetrics | €49/mo | 3 sources, 1 destination, 1 user | Agencies needing the broadest connector list |
| Power My Analytics | $41.63/mo billed annually | 5 sources, 5 accounts, 2 admin seats | Small teams on a tight budget |
| Funnel.io | $300/mo | 117 connectors, 13 lightweight destinations incl. Looker Studio (warehouse destinations need the $600/mo Business tier) | Enterprises paying for warehouse governance |
| Dataslayer | €29/mo | 3 connectors, daily refresh; free plan for 1 connector | Small teams that want a free starting point |
Porter Metrics prices by connected account, not by seat, which is why it undercuts everything else here for a one- or two-account stack. It dropped its old Solo/Teams tier names for a continuous per-account slider: one account runs $15 a month ($12.50 billed annually), dropping to $6.67 each at 5 accounts, $4.15 at 20 and $3.75 at 40, with every level shipping all four destinations and unlimited users. The free plan now covers unlimited connected accounts too, with a watermark on AI-generated dashboards. 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 $41.63 a month billed annually for 5 live sources, 5 accounts and 2 admin seats, with extra accounts and admins now priced through a volume-based add-on rather than one flat per-unit fee. A newer Grow tier sits above it at $83.29 a month for unlimited sources. 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 117 connectors and already includes Looker Studio among its 13 lightweight destinations, alongside Funnel’s own dashboards and spreadsheet/Conversion API exports. The warehouse-grade destinations switch on at Business, $600 a month, which adds 579 connectors and brings the destination count to 46 total, including BigQuery, Snowflake and Tableau. Flexpoints, Funnel’s purchased-capacity 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.
Advertised entry prices don’t show what three real sources cost once a stack needs more than the cheapest tier covers.
| Tool | Tier | Price for ~3 sources | Why |
|---|---|---|---|
| Porter Metrics | 5-account slider point | $33.35/mo billed annually | 1 account alone is $15/mo; the slider’s next point up covers 5 |
| Windsor.ai | Basic | $23/mo | Covers 3 sources, unlimited users |
| Coupler.io | Starter | $32/mo | Covers 3 accounts, 1 destination |
| Supermetrics | Starter | €49/mo | 3 sources, 1 destination, 1 user |
| Dataslayer | Starter | €29/mo | Covers 3 connectors, daily refresh |
| Power My Analytics | Business | $41.63/mo billed annually | Smallest paid tier; covers up to 5 |
| Funnel.io | Starter | $300/mo | Already includes Looker Studio among its 13 destinations |
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 and October 2026). Porter Metrics no longer has a fixed 3-account tier: it bills on a continuous per-account slider, where 1 account alone runs $15 a month and the next point up, 5 accounts, totals $33.35 a month billed annually ($6.67 each). Funnel.io’s Starter already includes Looker Studio at $300 a month; the $600 Business tier only matters once a warehouse destination like BigQuery or Snowflake is on the list.
Six of the seven connectors let you try before you pay, though “free” means different things depending on the vendor.
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.

Two of the cheapest options here are compared head to head in Coupler.io vs Windsor.ai and Coupler.io vs Porter Metrics.
Windsor.ai. Its $23-a-month Basic tier includes three sources, unlimited users and the full connector and destination catalogue, with no premium-connector or per-seat upcharge the way Porter Metrics and Supermetrics apply as a stack grows. That same $23 price also bundles five multi-touch attribution models, first-click, last-click, linear, Markov and algorithmic, a feature every other connector here either skips or sells separately. Porter Metrics is cheaper in absolute terms, from $15/month, but that covers only one account; add a second or third source and Porter’s per-account slider runs toward $33.35/month at the 5-account point, while Windsor.ai’s flat $23 doesn’t move.

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.
Porter Metrics, from $15 a month ($12.50 billed annually) 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.
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.
