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.

Audited prices verified against live vendor pricing pages — full dataset in the Pricing Gap Index.
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
Hourly refresh and unlimited seats ship on the cheapest point of its All-in pricing slider, $97 a month for 3 accounts per connector, which the bigger platforms reserve for pricier tiers. Both Google Sheets and Looker Studio are bundled in at every price point now. The trade-offs: a 30-plus connector list and a slider that tops out at 100 accounts per connector before Enterprise quoting takes over.
Best for: Agencies that want hourly refresh and unlimited seats with both Google Sheets and Looker Studio bundled in, on a budget that scales with account count · from $97/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 $41.63 a month billed annually, 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 $41.63/mo
Client-ready dashboards and automated PDF reports with unlimited users and white labeling on every tier. Individual runs $54 a month ($44 annually) for 3 dashboards and 15 sources, and the bill moves with dashboard and source counts, not headcount.
Best for: Agencies and in-house marketers who want client-ready dashboards and automated PDF/PPT reports without paying per seat, and who can live with a fixed set of report templates · from $44/mo
A real free plan for 1 connector and 1 user, then Starter at €29 a month for 3 connectors, with AI-assisted queries from the Advanced tier. The 60-plus connector list is shorter than the big names, so check your sources first.
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 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
One plan at €69 a month (€62 billed annually) covers 10 data sources with unlimited clients, users, dashboards and white-label reports. Sources past 10 cost €4.50 each, which is where the bill grows.
Best for: Agencies that want unlimited clients, users and dashboards under one plan and are comfortable paying per connected data source once they pass the 10 included in the base tier · from €62/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
Priced by client count: $75 a month for up to 5 clients and $125 for up to 10, with dashboards and white-labeled PDF reports included. Annual pricing and seat limits are not published, so ask sales before budgeting.
Best for: Agencies that want client-facing dashboards and white-labeled PDF reports bundled with the data connections, and who manage a client roster small enough to fit the published client caps · from $75/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 $12.50/mo
Catchr pipes marketing data not just into Looker Studio, Sheets and Power BI but directly into ChatGPT, Claude, Gemini and Copilot, one assistant more than Windsor.ai covers. Starter runs $24 a month for 3 platforms and 10 accounts, with a 14-day trial and no permanent free plan. The catch: the review base is just three ratings total across G2 and Capterra, with G2 itself flagging the sample as too thin to judge, and no Trustpilot presence at all.
Best for: Teams that want data flowing straight into ChatGPT, Claude, Gemini or Copilot and are comfortable being an early adopter on a thin review base · from $24/mo
Whatagraph bundles a dedicated Customer Success Manager and AI "IQ Agents" that build and monitor reports, a managed service rather than a self-serve connector. Pricing starts at €699 a month (around $812), billed annually only, with no free trial, no Excel destination, and Looker Studio or BigQuery access reserved for the custom-quoted Prime tier. Multiple 2026 reviewers call the forced annual billing switch "predatory," and Trustpilot scores outside Ireland run 2.2-2.5 out of 5.
Best for: Teams that want reporting handled by a dedicated CSM and AI agents rather than built in-house, and that can live with annual-only billing and a demo-gated sales process · from €699/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 | $41.63/mo billed annually (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 (117 connectors) | Enterprise data governance |
| Porter Metrics | From $15/mo (per-account slider, free plan unlimited accounts) | Solo or two-person shops |
| Two Minute Reports | $97/mo (3 accounts per connector, both destinations bundled) | Hourly refresh on the cheapest tier |
| DashThis | $54/mo (3 dashboards, 15 sources) | Agency dashboards, unlimited users |
| Dataslayer | Free (1 connector) or €29/mo (3 connectors) | Cheap Sheets and Looker Studio feeds |
| ReportGarden | $75/mo (up to 5 clients) | Client-capped agency reporting |
| Swydo | €69/mo (10 data sources) | Unlimited clients and users |
| Catchr | $24/mo (3 platforms, 10 accounts) | AI-assistant destinations, unproven track record |
| Whatagraph | €699/mo (~$812), annual-only (from 50 credits) | Managed, demo-gated reporting service |
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 $41.63 a month billed annually for five sources, five accounts and two admin seats, a fraction of what a similar source count runs on the bigger platforms. A newer Grow tier sits above it at $83.29 a month for unlimited sources and three admin seats. 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 117 connectors and 13 lightweight destinations (Funnel’s own dashboards, Looker Studio, spreadsheet and Conversion API exports), none of them warehouse-grade. Business, at $600, adds 46 destinations including BigQuery and Snowflake plus add-on measurement modules. 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, priced on a per-account slider instead of named tiers. One account runs $15 a month ($12.50 billed annually), dropping to roughly $4-$7 per account once a stack grows to 20-40 accounts, and the free plan now covers unlimited connected accounts rather than capping at three. It fits a solo operator or two-person shop that needs the wiring, not the whole platform.
Two Minute Reports sits between Porter and Supermetrics on price and leans on one thing the others gate: hourly refresh ships at every point on its pricing slider. The vendor dropped its old Lite/Pro/Business tier names for a single All-in plan priced by accounts per connector: $97 a month ($81 billed annually) at 3 accounts, $297 at 30 accounts and $597 at 100 accounts, the slider’s cap. Both Google Sheets and Looker Studio now ship bundled at every price point with no separate destination fee, and the catch is a connector list of 30-plus, a fraction of what Supermetrics or Windsor.ai cover. It fits an agency with a short, common-platform source list that wants client reports updating every hour without standing up a warehouse.
DashThis, Dataslayer and ReportGarden joined this guide in October 2026. DashThis is the dashboard-first option: client-ready dashboards and automated PDF reports with unlimited users and white labeling on every tier, priced by dashboard and source count from $54 a month ($44 billed annually). Dataslayer is the cheapest way to try a real connector, with a permanent free plan for 1 connector and Starter at €29 a month for 3, though its 60-plus connector list is shorter than Supermetrics or Windsor.ai. ReportGarden prices by client count instead, $75 a month for up to 5 clients and $125 for up to 10, with dashboards and white-labeled PDFs included; annual pricing and seat limits are not published. Swydo takes the opposite approach to per-client pricing: one plan at €69 a month (€62 billed annually) covers 10 data sources with unlimited clients, users and white-label reports, and each source past 10 adds €4.50 a month.
Catchr and Whatagraph joined this guide in November 2026, and they split the category in a new direction: buying friction and trust evidence, rather than price or connector count. Catchr ships four AI-assistant destinations, ChatGPT, Claude, Gemini and Copilot, on every plan including the cheapest one (Windsor.ai covers three). Starter runs $24 a month for 3 platforms and 10 accounts, with Looker Studio, Sheets and Power BI included; Growth at $239 a month adds BigQuery, Redshift and Snowflake. The trade-off is a review base thin enough that G2 itself calls it too small for buying insight, just two G2 reviews and one on Capterra, and zero presence on Trustpilot. It fits a team that wants data flowing straight into an AI assistant and is comfortable being an early adopter rather than leaning on a crowd-tested track record.
Whatagraph sells a managed service rather than a self-serve pipe: a dedicated Customer Success Manager and “IQ Agents” that build and monitor reports sit on every plan, alongside unlimited users and reports. That comes at the highest entry price in this guide, €699 a month (roughly $812) billed annually only, with no free trial, no self-serve signup and no Excel destination at all; Looker Studio and BigQuery exports are both locked to the custom-quoted Prime tier. Multiple 2026 Capterra reviewers independently describe a forced annual-only billing switch as “predatory,” and Trustpilot scores outside Ireland sit at 2.2-2.5 out of 5. It fits a team that wants reporting handled for them and has the budget and patience for a sales-gated setup, not one looking for a quick, cheap connector.
One thing none of these thirteen 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.

Ranked by entry monthly price, cheapest first: Porter Metrics (from $15, one account, $12.50 billed annually), Windsor.ai Basic ($23, three sources), Catchr Starter ($24, 3 platforms and 10 accounts), Coupler.io Starter ($32, three accounts), Power My Analytics Business ($41.63 billed annually, five sources), Supermetrics Starter (€49, three sources) and Funnel.io Starter ($300 billed annually, 117 connectors). Two Minute Reports lands in the middle at $97 a month for 3 accounts per connector, well above the small-stack tools but far under Funnel.io, and it is the only one here with hourly refresh on its cheapest plan. Among the October 2026 additions, Dataslayer Starter (€29, three connectors) sits near the bottom of the range, DashThis Individual ($54, three dashboards) lands next to Supermetrics, and ReportGarden Standard ($75, five clients) is priced per client rather than per source. Swydo (€69 for 10 sources, unlimited clients) suits agencies with many small clients on few platforms. Whatagraph sits at the very top of the range and in a different billing category entirely: Max starts “from €699/mo” (roughly $812), billed annually only with no monthly option, well past even Funnel.io’s enterprise-priced Starter tier.
Each entry tier leaves something out. Porter’s $15 entry point (billed monthly; $12.50 if annual) covers exactly one connected account, fewer than the unlimited accounts Porter’s own free plan now includes. Windsor.ai’s Basic tier caps refresh at daily; hourly needs Standard ($118/mo) and 15-minute syncs sit on the $598/mo Professional plan. Coupler.io’s Starter bundles three accounts and one destination, with every extra account costing $5.99 a month and refresh stuck at daily until Pro. Supermetrics Starter ships one destination and one user at a similar price point, though Supermetrics no longer publishes a specific refresh cadence per tier. Power My Analytics Business includes just two admin seats and five accounts, with extra accounts and admins now priced through a volume-based add-on rather than one flat per-unit fee. Funnel.io’s $300 Starter ships only 13 lightweight destinations, none of them warehouse-grade; the BigQuery and Snowflake connections that justify an enterprise data hub only unlock among Business’s 46 destinations at $600 a month. Catchr’s $24 Starter covers only 3 platforms and 10 accounts, with BigQuery, Redshift and Snowflake held back for the $239/mo Growth tier, and the two annual-billing figures published on its own pricing page don’t fully reconcile. Whatagraph’s €699 Max entry covers “from 50” source credits but gates Looker Studio export and BigQuery entirely to a custom-quoted Prime tier, with no published monthly-billing option at all.
Prices as we checked them in July, October and November 2026.
Dataslayer. It holds the highest combined rating of the thirteen tools in this guide: 4.8 out of 5 on G2 across roughly 310 reviews, and 4.7 out of 5 on Capterra across 82. Two Minute Reports scores higher on G2 at 4.9, but on just 13 reviews, too thin a sample to outweigh Dataslayer’s larger base. Swydo (4.7/5 from 114 G2 reviews) and Funnel.io (4.5/5 from 165 G2 reviews, 4.7/5 on Capterra from 19) are the next most consistently well-reviewed, both clearing 100-plus ratings on at least one platform. The two November 2026 additions don’t challenge that top spot: Catchr’s 4.5/5 G2 score rests on just 2 reviews, a sample G2 itself calls too thin for buying insight, and Whatagraph’s otherwise solid 4.5/5 on G2 (277 reviews) and 4.4/5 on Capterra (84) sit next to Trustpilot scores of 2.2-2.5 out of 5 outside Ireland. Ratings pulled directly from each tool’s G2 and Capterra listings, checked October and November 2026.

Porter Metrics is the cheapest paid plan here, from $15 a month ($12.50 billed annually), though that price covers only one connected account. Windsor.ai's $23 Basic tier is the next cheapest and bundles three sources with unlimited users, which matters more once a second person needs access. Catchr's $24/mo Starter plan sits just above Windsor.ai's, for 3 platforms and 10 accounts, but note it's a trial-only connector with no permanent free plan and a review base too small for independent confirmation.
Coupler.io, Porter Metrics and Windsor.ai are the three with an actual permanent free tier. Coupler.io gives one account and one destination, Porter Metrics now gives unlimited connected accounts with every destination unlocked (AI-generated dashboards carry a watermark on this tier), and Windsor.ai's Forever Free tier drops to one source and one user once its 30-day trial ends. Power My Analytics' free plan only renders sample data, not real accounts, and Supermetrics skips a free tier for a 14-day trial instead.
