We built Dataslayer as an alternative to Supermetrics back in 2018 because we kept seeing the same problem: agencies getting surprise bills when they added a second user, or discovering their "affordable" plan didn't include basic features they assumed were standard.

Since then, the market has evolved. More tools have entered the space, each taking a different approach. Some chase 500+ connectors. Others focus on complex ETL transformations. Some keep pricing transparent, others hide it behind "contact sales."

This guide covers the six alternatives we think are worth your time, including an honest look at where Dataslayer fits and where it doesn't. All pricing comes from official sources, reviews are verified from G2, and we'll tell you specific scenarios where each tool makes sense.

If you're evaluating options right now, you probably care about transparent pricing, unlimited team access, specific connectors, or better support. Let's find out which tool actually delivers.

Dataslayer: Built Around How Agencies Actually Work

Let's start with us since this is our blog. You deserve to know exactly what we do differently and why it matters.

‍

The core difference: Unlimited users on every plan

When agencies switch to Dataslayer, they usually tell us the same story: "We had 5 people who needed data access, and our old tool charged €99 per extra user. That's €396/month just for seat licenses before any actual features."

With Dataslayer, your entire team gets access. Junior analysts, freelance specialists, account managers, even interns building dashboards. No per-seat fees, period.

‍

What's included:

We connect 50+ marketing platforms: Google Ads, Facebook Ads, Instagram, LinkedIn Ads, TikTok Ads, Twitter, Pinterest, Snapchat, YouTube, Google Analytics 4, Search Console, Bing Ads, Amazon Ads, Apple Search Ads, Shopify, and more.

Send data to any destination you're using: Google Sheets, Looker Studio, BigQuery, Power BI, Excel, Qlik, Amazon S3, Redshift. All included. No extra charges per destination.

We're ISO 27001 and 27701 certified, enterprise-grade security for client data. Everything encrypted in transit and at rest.

‍

Pricing:

Dataslayer offers transparent pricing designed for agencies of all sizes. Plans start at €25/month with unlimited users, all connectors, and all destinations included.

Every plan includes all 50+ connectors and all destinations. Zero hidden fees.

‍

What real users say (G2: 4.7/5 stars, 156 reviews):

"Dataslayer is a very easy to use tool and with a really interesting price in comparison with other similar options in the data extraction tools market." (5/5 stars)

"The unlimited users feature alone saved us thousands. We have 12 people accessing data now without any extra cost." (5/5 stars)

"Works great for our main sources (Google, Facebook, LinkedIn). Would love to see more niche connectors added." (4/5 stars)

That last review is fair. We focus on the connectors most agencies actually use daily rather than chasing 500+ integrations. But we are always working on offer more connectors.

‍

Real numbers:

A typical agency with 5 people, 15 data sources, and 30 client accounts:
‍

• Dataslayer Medium Agency: €82/month (€984/year)
• Alternative with per-seat pricing: €553/month (€6,636/year)
• You save: €5,652 annually

‍

Dataslayer makes sense if: You're managing 3 to 100+ clients. Your team has multiple people needing data access. You use standard marketing platforms and want setup done in 30 minutes. Transparent pricing matters because you've dealt with surprise fees before.

The Other 5 Alternatives Worth Your Time

1. Funnel.io: Maximum Connectors for Enterprises

Funnel.io is built for enterprises needing every possible integration.

Their strength: 590+ data sources, the most extensive library available. Their Data Hub stores historical data with currency conversion, metric harmonization, and cross-platform blending. For large organizations processing millions in ad spend across dozens of platforms, Funnel's engineering is sophisticated.

Pricing (official website):
‍

• Free plan: 4 connectors, 400 flexpoints, 1 destination
• Starter: approximately $240 to 400/month
• Business: approximately $600 to 800/month
• Enterprise: Custom

Users on G2 (4.6/5 stars, 158 reviews) report average annual costs around $6,000 to 8,000 for business plans.

One verified user wrote: "Funnel's data hub is a game changer for our Fortune 500 reporting needs. The transformation rules save us 40+ hours monthly."

Choose Funnel.io if: You genuinely need 50+ data sources including specialized platforms. You have dedicated data engineering resources. Your budget accommodates $600+/month. Advanced transformation is part of daily workflows.

Honest comparison: Funnel offers more connectors and more sophisticated transformation features. For enterprises managing dozens of niche platforms, that breadth matters. For using standard marketing platforms, Dataslayer covers essential needs at a fraction of the cost with simpler setup.

2. Improvado: For Massive Data Operations

Improvado targets companies processing hundreds of millions of data rows annually with marketing budgets exceeding $10 million.

Their approach: You get a dedicated engineering team that builds custom connectors to your exact specifications. With 500+ prebuilt integrations and credit-based customization, they're designed for enterprises where "contact sales" pricing makes sense.

Pricing (official website):
‍

• Growth: Organizations processing up to 200M rows/year
• Advanced: Up to 600M rows/year
• Enterprise: 1B+ rows/year

G2 reviews (4.6/5 stars) indicate starting prices around $1,200/month, with most enterprise implementations between $3,000 to 10,000/month.

A verified review: "We saw an 80% reduction in time spent on data prep. What took hours is now automated."

Choose Improvado if: You process 100M+ data rows yearly. $1,000+/month budget is approved. You need SOC 2 compliance and enterprise SLAs. You have IT/data teams managing infrastructure.

Important note: Improvado is an ETL platform, not a reporting tool. You still need Looker Studio, Tableau, or Power BI for visualization.

3. Porter Metrics: Pay Per Connection Pricing

Porter Metrics takes a different angle: you pay per account connection, not per user or destination.

Their model (official pricing):
‍

• 1 account: $15/month
• 5 accounts: $40/month ($8 each)
• 20 accounts: approximately $160/month
• 40+ accounts: Custom pricing

Annual plans save 17%. Unlimited users. Both Looker Studio and Google Sheets included.

From G2 (4.5/5 stars): "Porter Metrics makes connecting data to Looker Studio incredibly easy. Set up everything in just a few minutes."

Choose Porter if: You need exactly 5 to 30 account connections. Pay as you grow appeals to you. You primarily use Looker Studio or Google Sheets.

Quick comparison: Porter's per-connection model works for specific scenarios. With 10 to 15 accounts, Porter costs approximately $80 to 120/month. Dataslayer Medium Agency at €82/month includes up to 100 accounts, becoming more economical as you scale.

4. Windsor.ai: Attribution Focused Platform

Unlike pure connectivity tools, Windsor.ai specializes in multi-touch attribution modeling with 325+ integrations.

Pricing (official website):
‍

• Basic: $19/month (3 users)
• Standard: $99/month (10 users, attribution models)
• Plus: $249/month (unlimited users)
• Professional: $499/month (API access, custom models)

A G2 user (4.4/5 stars) noted: "Finally able to track the full customer journey across 8 touchpoints. Our attribution model showed channels we were undervaluing."

Choose Windsor.ai if: Attribution modeling is central to your strategy. You run multi-touch campaigns across 5+ channels. You need to demonstrate marketing ROI with sophisticated attribution, not just data connectivity.

5. Whatagraph: Visual Reporting Built In

Whatagraph combines data integration with its own visual reporting platform, so you don't need separate BI tools.

Pricing (official website):
‍

• Professional: $223/month (3 users)
• Premium: $335/month (5 users, white-label)
• Custom: Enterprise pricing

Includes 45+ native integrations.

From G2 (4.3/5 stars): "Saved 63 hours per month on reporting. Visual dashboards are client ready without additional work."

Choose Whatagraph if: You want data integration AND reporting in one platform. Visual client-facing dashboards are high priority. You value aesthetics and user experience. You're willing to pay for integrated visualization rather than using Looker Studio or Power BI separately.

How to Actually Decide

Skip the feature comparison spreadsheet. Here's what matters:

1. How many people need access?

If it's 5+, eliminate tools with per-seat pricing. You'll burn thousands on seat licenses alone.

Unlimited users: Dataslayer, Porter Metrics

2. Do you really need 100+ connectors?

Most agencies actively use 8 to 12 sources. Google Ads, Facebook, Instagram, LinkedIn, TikTok, Analytics, Search Console handles 90% of client work.

Need niche platforms: Funnel.io (590 connectors)

Standard platforms work: Dataslayer (50+ connectors), Porter (45+ connectors)

3. What's your realistic budget?

Be honest. Not "what we could theoretically spend" but "what we're comfortable committing."
‍

• Under €600/year: Dataslayer Freelance
• €600 to 1,500/year: Dataslayer Small/Medium Agency, Porter
• €1,500 to 10,000/year: Dataslayer Large Agency, Whatagraph, Funnel.io
• €10,000+/year: Funnel.io, Improvado

4. Need advanced ETL transformation?

Currency conversion across 40 countries? Complex metric normalization? Multi-source blending with custom rules?

Yes: Funnel.io or Improvado

No: Simpler tools work fine (and cost less)

5. Test with real data

Sign up for trials and build one actual client report:
‍

• Dataslayer: 15 days, no credit card
• Funnel.io: contact for demo
• Porter Metrics: 14 days

See which clicks with your workflow.

Common Migration Questions

"Will my reports break during migration?"

Not if you plan it right. Run both tools in parallel for 1 to 2 weeks during transition. Dataslayer offers a free migration tool that converts existing queries automatically.

"How long does setup take?"

• Dataslayer, Porter: 30 minutes to 2 hours
• Funnel.io, Improvado: 1 to 2 weeks with guided onboarding

"What about historical data?"

Export from your current tool before canceling. Most platforms allow CSV exports. For long-term storage, send historical data to BigQuery or similar warehouses.

"What if my connector breaks?"

Check reliability guarantees:
‍

• Dataslayer: Daily automated testing, typically 99%+ uptime
• Enterprise tools: SLA guarantees (usually 99.5 to 99.9%)
• Budget tools: Best effort support

The Bottom Line

There's no universal "best" tool, it depends on your specific situation.

For most agencies (5 to 50 clients) that value transparent pricing, unlimited team access, and quick setup, Dataslayer offers the best balance of features and cost.

For enterprises (100+ clients) with complex transformation needs and $800+/month budgets, Funnel.io or Improvado provide sophisticated capabilities worth the premium.

For freelancers, Dataslayer's Freelance plan or Porter Metrics' entry tiers work well.

For attribution-focused teams, Windsor.ai solves a different problem than pure connectivity.

The market has matured enough that you don't need to accept pricing that punishes growth or pay for features you'll never use.

Frequently Asked Questions

Which alternative has the most data connectors?

Funnel.io leads with 590+ connectors, followed by Improvado (500+) and Coupler.io (380+). However, in our experience working with agencies, most actively use 10 to 15 sources regularly.

‍

Is there a completely free option?

Native platform connectors (like Google's BigQuery Data Transfer) are free but extremely limited. Funnel.io has a free tier with 4 connectors. For real functionality, budget at least €25 to 50/month.

‍

How do these tools handle API rate limits?

Quality platforms manage this automatically with request throttling and retry logic. Red flag: tools that don't communicate rate limits clearly until your reports break.

‍

What about data security?

Look for SOC 2 Type II, ISO 27001, GDPR compliance. Dataslayer has ISO 27001 & 27701 certification. Enterprise users should verify data residency options (US vs EU processing).

‍

Can I use multiple tools simultaneously?

Yes. Some agencies use Dataslayer for 90% of sources and maintain a secondary tool for 1 to 2 niche connectors. Often cheaper than enterprise pricing on a single platform.

‍

What's the best alternative for small budgets?

Dataslayer's Freelance plan at €25/month offers unlimited users and all connectors. Porter Metrics starts at $15/month for single account connections. Both provide full functionality without enterprise costs.
