If you report on more than one ad account, you already know the Monday-morning ritual: pulling CSVs from five platforms and stitching them into one spreadsheet by hand. These connectors automate that pull straight into Looker Studio, Google Sheets, Excel or BigQuery on a schedule you set. Supermetrics is the safest default for most agencies, thanks to the deepest connector list and destination options here. If budget decides everything, Power My Analytics gets a small stack of live sources onto a dashboard for well under half the price of comparable mid-tier plans. Past that, the right pick depends on how many client accounts you juggle and which destination you actually report into.
ToolsGavel's top pick: Supermetrics (4.4/5, from €49/mo) — The category's original, and still the broadest: hundreds of connectors feed Looker Studio, Sheets, Excel or a warehouse. You pay for that reach: sources, users and destinations are billed separately, but for an agency juggling many client accounts, the coverage is hard to beat.

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
Five live sources into Sheets, Looker Studio or Power BI for $49.95 a month, a fraction of what comparable source counts cost on bigger platforms. The free plan only shows sample data, so budget for Business from day one if you need real numbers.
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
The only free tier here that isn't a sample-data demo: one account, one destination, manual refresh. Enough to confirm a connector pulls the data you need before a card gets charged, and paid tiers price by data connection rather than by seat.
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
Every connector and destination ships on every paid plan, with unlimited users included even on the entry tier. No add-on fees for extra seats or premium sources, so the invoice doesn't creep as the team grows.
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
Built for marketing teams running global media budgets across 500-plus connectors, with a real data warehouse layer and governance controls. Starter lists at $300 a month, but real contracts often run closer to four figures once measurement gets added.
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
No dashboard of its own, just a cheap pipe from Google-side accounts into Looker Studio, Sheets or BigQuery. A solo marketer or two-person shop can run a handful of client accounts for well under $20 a month.
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
Entry pricing and core fit for each, at a glance:
| Tool | Entry price | Best for |
|---|---|---|
| Supermetrics | €49/mo (3 sources, 1 destination) | Broadest connector coverage |
| Power My Analytics | $49.95/mo (5 live sources) | Small stacks on a budget |
| Coupler.io | Free (1 account) or $32/mo (3 accounts) | Testing before you commit |
| Windsor.ai | $23/mo (3 sources, unlimited users) | Flat, predictable pricing |
| Funnel.io | $300/mo (121 connectors) | Enterprise data governance |
| Porter Metrics | About $15/mo (a few Google sources) | Solo or two-person shops |
Supermetrics is the category’s default choice, and the connector list explains why: it covers more ad platforms, CRMs and niche sources than anything else on this list, feeding into Looker Studio, Sheets, Excel or a full data warehouse. Pricing splits sources, users and destinations into separate line items. Starter runs €49 a month for three sources and one destination, and each extra source, user or destination gets billed on top. For an agency managing a long client roster where breadth matters more than a low sticker price, it stays the safe pick.
Power My Analytics answers a narrower question: how do you get five or six live ad accounts onto a dashboard without paying Supermetrics-Growth money for it? The Business tier costs $49.95 a month for five sources, five accounts and two admin seats, a fraction of what a similar source count runs on the bigger platforms. The free plan only shows sample data, though, so there’s no real no-cost tier to lean on while you decide.
Coupler.io offers the one permanent free plan here: one account, one destination, manual refresh, no expiry date. That’s enough to confirm a connector pulls the data you need before a card gets charged. Paid tiers start at $32 a month ($24 billed annually) and price by data connection rather than by seat, so a small team can add people without extra fees, though an account-heavy business can hit the connection ceiling sooner than expected.
Windsor.ai sells predictability. Every plan, including the $23-a-month Basic tier, ships the full connector and destination catalogue plus unlimited users, with no premium-connector upcharge and no per-seat fee. That keeps budgeting simple for an agency adding team members mid-contract. The tradeoff lands on refresh speed and account caps: hourly and 15-minute syncs, along with the highest account ceilings, sit on the $499-a-month Professional plan.
Funnel.io targets a different buyer: a marketing organization moving real ad spend across dozens of platforms that needs a governed data warehouse layer, not a spreadsheet feed. Starter lists at $300 a month for 121 connectors with no export destinations included. Business, at $600, is where destinations and add-on measurement modules unlock. Buyer-reported contracts often land near $1,000 a month once usage scales, pricing out most small teams before they start.
Porter Metrics goes the other direction: no dashboard, no BI layer, just a cheap pipe from Google-side accounts into Looker Studio, Sheets or BigQuery. Published pricing puts the entry tier around $15 a month for a handful of accounts, rising to roughly $49 once BigQuery or extra accounts enter the picture, and cost tracks per account rather than a fixed seat count. It fits a solo operator or two-person shop that needs the wiring, not the whole platform.
One thing none of these six touch: data a platform doesn’t expose through an official API at all, like competitor pricing or public listings. That’s a job for a web-scraping and proxy tool like Bright Data, not a reporting connector.
For most agencies and in-house teams reporting across more than a couple of platforms, Supermetrics remains the default. The connector breadth and destination options cover more edge cases than any competitor here, and the modular pricing at least means you pay only for what you use. If budget decides everything and your stack is small, Power My Analytics gets real, live data flowing for under $50 a month. Solo operators running everything through Looker Studio should start with Porter Metrics instead. It’s the cheapest way to stop copying export files by hand. Skip Funnel.io unless you’re already managing enterprise-scale ad spend, since its pricing only makes sense at that volume.
