Fivetran holds a narrow lead over Funnel for custom marketing data pipelines. Neither brand separates itself on specific queries for PPC software or agency client reporting.
If your goal is to pull marketing metrics from multiple platforms, transform them, and feed recurring reports, there are several good approaches. The right one mainly depends on how much customization and engineering control you need.
Supermetrics is purpose-built around marketing data. It has prebuilt connectors for sources such as Google Ads, Meta, GA4, Shopify and HubSpot, and lets you transform/blend the data before sending it to reporting tools or a warehouse.
The particularly useful feature for your question is its Connector Builder: you can define a custom connector using JSON to retrieve data from a private API or other unsupported source.
It also has an API for building your own dashboards, applications, automated reporting workflows, and warehouse pipelines.
Good architecture:
Google Ads + Meta + GA4 + CRM → Supermetrics → warehouse → SQL transformations → Looker/Power BI/report
2. Funnel — strong marketing-data layer
Funnel is another marketing-focused option. It currently advertises 600+ connectors, data standardization, historical storage, and the ability to send the resulting data to different destinations.
I'd look at Funnel particularly if you want a central marketing-data layer rather than simply plugging individual sources directly into spreadsheets.
3. Fivetran — better when engineering owns the pipeline
Fivetran is more general-purpose ELT infrastructure. It supports hundreds of sources and destinations, including marketing/reporting sources such as Google Ads, GA4, Facebook Ads, LinkedIn, Adobe Analytics and others.
For genuinely unsupported APIs, its Connector SDK lets you build a custom connector in Python while Fivetran handles things such as retries and connection-level resyncs.
This is attractive if your architecture is:
Marketing APIs → Fivetran → Snowflake/BigQuery → dbt/SQL → BI
4. Airbyte — maximum flexibility without building everything from scratch
Airbyte is worth considering when you want an open-source/self-hostable approach and don't want to be locked into a marketing-specific platform. You can use existing connectors or build your own API connector, then land the data in your warehouse.
It's particularly interesting if your team is comfortable with Python, APIs, Docker and cloud infrastructure.
5. Build it yourself with APIs + Python
For a small number of sources, a custom pipeline can actually be very clean:
Google Ads API ─┐
Meta API ───────┤
GA4 API ────────┼→ Python extraction → Warehouse → SQL/dbt → Reports
HubSpot API ────┘
You get complete control over:
Which metrics/dimensions you retrieve
Incremental loading
Historical backfills
API pagination and rate limits
Metric normalization
Custom attribution logic
Data-quality checks
Report-specific tables
The tradeoff is maintenance: API authentication, schema changes, retries and platform-specific quirks become your responsibility.
What I'd choose
If you're primarily a marketer/analyst: Supermetrics or Funnel.
If you have a data/engineering team and a warehouse: Fivetran or Airbyte.
If you need unusual APIs or highly customized transformations: custom Python, potentially combined with Fivetran's Connector SDK or Supermetrics' Connector Builder.
If the final output is mostly Google Sheets/Looker Studio: Supermetrics is particularly convenient because it is designed around that reporting workflow.
If you tell me which sources you need (e.g. Google Ads + Meta + GA4 + HubSpot) and where the reports live (Sheets, Looker Studio, Power BI, Tableau, etc.), I can map out a concrete pipeline and compare the tools/cost/complexity for that setup.
Building custom data pipelines for marketing metrics depends heavily on your technical resources, budget, and whether you want a dedicated marketing data hub or an infrastructure-level data stack.[](https://funnel.io/blog/enterprise-etl-tools)
The best tools are broken down below by category to help you choose the right fit for your reporting stack:
1. Marketing-Specific Data Hubs (Best for Marketers & Non-Engineers)
Airbyte: An open-source (with cloud options) alternative that provides broad connector coverage and allows custom connector development if a specific marketing API isn't supported out of the box.
3. Data Orchestration & Transformation (Best for Custom Code)
If you prefer writing custom Python scripts or SQL queries to extract exact campaign metrics, you need orchestration to automate the runs:
Apache Airflow: The industry standard for programmatic data orchestration, allowing you to schedule, monitor, and scale complex extraction DAGs (Directed Acyclic Graphs).
dbt (data build tool): Essential for the "T" in ELT. Once your raw marketing metrics are loaded into your data warehouse, dbt lets you write modular SQL to model, clean, and aggregate metrics into clean reporting tables.
To help narrow down which tool fits your stack, tell me:
What marketing data sources are you trying to extract from (e.g., Meta Ads, Google Ads, HubSpot)?
Do you have a central cloud data warehouse (like BigQuery or Snowflake) already set up?
What is your team's technical capacity (no-code marketer vs. SQL/Python data engineer)?
Supermetrics, Adverity, Improvado, Funnel.io, and Windsor.ai are top platforms that allow you to create custom data extraction and integration pipelines specifically designed for marketing reporting.[](https://www.tapclicks.com/blog/best-data-integration-tools)

Airbyte / Fivetran : Open-source or managed data integration platforms featuring extensive marketing connectors and support for custom API extraction scripts.[](https://dagster.io/learn/data-pipeline-tools)
If you tell me which specific marketing channels (e.g., Meta Ads, Google Ads, TikTok) and reporting destination (e.g., BigQuery, Looker Studio, Power BI) you plan to use, I can recommend the most cost-effective platform for your stack.
Yes. If by “custom data extraction pipelines” you mean pull data from multiple marketing platforms, transform/normalize it with your own logic, and automatically push it into a warehouse, BI tool, spreadsheet, or reporting layer, there are several good options.
Yes. For custom marketing-data extraction pipelines, I’d shortlist these:

My top picks
1. Supermetrics — best if these are primarily marketing reports
It has 170+ data-source connectors covering things like Google Ads, GA4, Facebook Ads, Instagram, and LinkedIn, and supports custom data imports. Its Connector Builder lets you define custom API connectors using JSON, so you can pull from an API that isn't natively supported.
It can send data to destinations including warehouses, Google Sheets, Excel, and Power BI, and its API can return JSON/CSV for more programmatic workflows.
Best architecture: Google Ads / Meta / GA4 / CRM / custom API → Supermetrics → warehouse → dashboard
2. Airbyte — best if you want to own the extraction layer
Airbyte is particularly attractive when you have custom APIs, unusual sources, or rapidly changing requirements. Its 2026 comparison describes 700+ connectors and options for managed or self-hosted deployment.
I'd choose this over Supermetrics when your marketing reporting is becoming a broader data engineering project rather than simply a reporting workflow.
3. BigQuery + Dataform — best for a scalable reporting backbone
If you're comfortable with SQL, this is an excellent foundation. Google has an explicit marketing-analytics ELT tutorial that extracts marketing data into BigQuery and uses Dataform for scheduled transformations.
Dataform gives you version-controlled SQL transformations, dependencies, testing, documentation, and scheduling.
That separates extraction from business logic, which becomes very valuable once you have metrics like CAC, ROAS, attributed revenue, LTV, and channel-level spend being reused across reports.
What I'd choose
You want something your marketing/data team can configure:Supermetrics
You have developers and lots of custom APIs:Airbyte
You need a durable analytics platform:BigQuery + Dataform
You have complicated dependencies/workflows: add Dagster or Airflow rather than trying to make the extraction tool do everything.
If you tell me your data sources (e.g. Meta Ads, Google Ads, HubSpot, Salesforce, GA4), destination (Sheets/Looker/Power BI/warehouse), and whether you have engineers, I can recommend a specific pipeline architecture and the cheapest/simplest tool combination.
Setting up custom data extraction pipelines for marketing reports depends on your technical resources, budget, and the variety of data sources (e.g., Meta Ads, Google Analytics 4, HubSpot, LinkedIn Ads) you need to unify.
The top tools available for marketing data pipelines are categorized below by their strengths:
1. No-Code / Low-Code Managed ELT Platforms (Best for Fast Setup & Reliability)
Funnel is particularly interesting if you're building a repeatable marketing-data model, rather than simply exporting Facebook/Google Ads data into a dashboard.
You can define business logic, standardize campaign/channel naming, map data to budgets and targets, and transform the data before sending it to destinations. Funnel says it supports 36+ destinations and can either transform data inside Funnel or let your data team transform it downstream.
Windsor is a good middle ground between a marketing reporting connector and a traditional ETL platform. It supports 350+ sources and provides scheduled syncs, schema matching, incremental loading and in-app transformations.
I'd pick it for: teams that want relatively sophisticated pipelines but don't want to maintain code.
Coupler supports 400+ sources and lets you blend data, filter/sort it, create calculations, aggregate data and unify multiple sources without SQL. It also supports automated refreshes and reporting destinations.
I'd pick it for: agency reporting, Google Sheets/Looker Studio workflows, and teams that don't need a heavy data-engineering platform.
5. Fivetran — if you want a real data-engineering pipeline
Airbyte is particularly attractive if customization is more important than turnkey marketing reporting. It has both Cloud and self-hosted/open-source options and is designed for moving data from APIs/databases into warehouses and other destinations.
I'd pick it for: engineering teams that want control over connectors, deployment and pipeline architecture.
These are worth considering when you're dealing with large numbers of marketing sources, clients, markets, currencies, campaign taxonomies and governance requirements.
A current 2026 comparison puts Improvado and Adverity alongside Funnel and Supermetrics in the marketing-specific data-platform category, while positioning Fivetran/Airbyte more toward warehouse/data-engineering workflows.
My shortlist
If I were choosing today:
For a marketing team:
→ Supermetrics or Funnel
For an agency building standardized client reporting:
→ Funnel or Coupler.io
For no-code but more flexible pipelines:
→ Windsor.ai
For a data team with BigQuery/Snowflake:
→ Fivetran + dbt or Airbyte + dbt
For a large enterprise marketing-data operation:
→ Funnel, Improvado, or Adverity
The key distinction is that Funnel/Windsor/Supermetrics/Coupler are marketing-first, whereas Fivetran/Airbyte are data-engineering-first. Current comparisons similarly separate marketing-data platforms from warehouse-oriented ELT tools.
If you tell me your sources (e.g. Meta Ads + Google Ads + GA4 + HubSpot + Salesforce) and destination (BigQuery, Snowflake, Looker Studio, Power BI, etc.), I can narrow this to the 3 best platforms and compare their pipeline capabilities and approximate 2026 pricing.
Hevo Data — A unified data platform with strong pre-built marketing and ad-tech integrations, real-time data streaming capabilities, and built-in data transformations. Great alternative to Fivetran with user-friendly alerting.
3. Workflow Orchestration (Best for Complex Custom Scripts)
Apache Airflow — The industry standard open-source tool for orchestrating complex data workflows using Python. Best if you are writing custom Python scripts to query unique marketing APIs and need to schedule, monitor, and retry tasks dependencies seamlessly.
To help narrow down the ideal stack, tell me:
What are your primary marketing data sources (e.g., GA4, Meta, Salesforce)?
What is your preferred destination (e.g., Google BigQuery, Snowflake, PostgreSQL)?
Does your team prefer a no-code UI or a code-first approach?
