Alternatives to Fivetran: Best ETL Tools 2025

May 5, 2025
5 min read

Fivetran is a popular data movement platform used to aggregate data into a warehouse and transform it for analysis and operational use. It's a powerful solution—but not without its flaws and limitations. If you’ve run into challenges with Fivetran or are considering whether to integrate it, this guide breaks down the top Fivetran alternatives.

We’ll cover core ETL capabilities, marketing-specific connectors, ease of use, transformation options, and Fivetran’s key limitations for marketing teams—plus how each alternative addresses those gaps.

Fivetran Overview

Fivetran is a data movement platform
Fivetran interface

Fivetran is a fully managed cloud ELT platform or a data management platform. Fivetran’s pipeline is known for being robust and scalable, handling large volumes and incremental updates.

Fivetran offers a large library of over 700 pre-built connectors spanning many domains​. But in terms of marketing sources, Fivetran’s site lists around 90 marketing-specific data sources, including Google Ads, Facebook Ads, LinkedIn Ads, Twitter Ads, Google Analytics, HubSpot, Salesforce, Marketo, Mailchimp, Shopify, and so on.

Custom connectors
If a needed source is not supported, Fivetran allows two approaches:
  • you can request a new connector, which they may build if there’s enough demand,
  • or you can use their Function Connector feature to pull data from a custom API using code.Essentially, you write a bit of Python or use an AWS Lambda to fetch data, and Fivetran will accept it into the pipeline.

Fivetran does not typically build custom connectors for a single client on the fly (whereas some competitors will), so if a niche source isn’t supported, marketers might be stuck waiting or need developer help to use the function connector.

For data transformation, Fivetran integrates with dbt (Data Build Tool), an open-source SQL transformation framework​. Fivetran allows you to schedule dbt models, to run after data is loaded, and even provides some UI around scheduling and monitoring those transforms​. 

Fivetran is designed to load data into cloud data warehouses and lakes. It supports all the big names: Snowflake, Google BigQuery, Amazon Redshift, Azure Synapse, etc. It also can load to data lake storage like Amazon S3, Google Cloud Storage, or Azure Blob.

Fivetran does not output to spreadsheets or BI tools directly, you’d instead connect those tools to the warehouse. The positive is that since the data is in a warehouse in a standard format, any BI tool can be connected.

Fivetran does not offer any native reporting or dashboarding. It’s a pure data pipeline service. It’s important to highlight that Fivetran is meant to be one component in a modern data stack, not an end-to-end platform.

Best for

Fivetran is best for brands with internal technical resources that want pure ETL platform (with no advanced marketing-specific transformations or marketing intelligence features) and can handle the data modeling on their own.

Fivetran Pricing

Fivetran employs a usage-based pricing model centered around Monthly Active Rows (MAR). The more your data changes, the more you pay.

The platform offers several pricing tiers that provide MAR allowances and different features, for example, frequency of data sync, integration for dbt, and others. 

Fivetran Pros

  • Fully managed, low-maintenance ELT pipelines.
  • Reliable schema management and incremental updates.
  • Native dbt integration for post-load transformations
  • Fivetran maintains a community forum and a knowledge base for common questions. 

Fivetran Cons

  • Fivetran is primarily designed for raw data replication, it doesn’t provide a built-in environment for data analysis or extensive pre-load transformation. It expects you to do that in your warehouse.
  • Pricing is unpredictable and scales quickly with data volume.
  • No built-in dashboards or analytics—external BI tools are required.
  • No pre-load transformation support, all modeling must happen post-load. Marketing teams often need to, for example, map campaign IDs to names, or combine data from multiple platforms – with Fivetran, you must do that later in SQL or via dbt.
  • Limited flexibility for marketers or non-technical teams.
  • Custom connector requests are only considered if there’s broad demand. While Function connector requires code for unsupported sources.

Best Fivetran Alternatives

The good news is that if Fivetran doesn’t meet your company’s data-integration needs, there are several alternatives to consider. Read on as we delve into the most popular Fivetran alternatives and competitors.

1. Improvado 

Improvado is a marketing intelligence and analytics platform.
Unlike Fivetran, Improvado is a marketing-focused platform and supports both data movement and reporting.

By contrast, Improvado is a complete marketing data and intelligence platform. It handles not only the data pipeline but also the preparation of data for marketing analytics, campaign monitoring, and marketing intelligence.

Improvado supports over 500 marketing and sales data sources—significantly more than Fivetran’s marketing-specific count. This includes not only the common platforms Fivetran supports, but also many niche or region-specific marketing tools, such as Walmart Connect, Samsung DSP, and others.

Improvado also supports uploading offline data (like Excel, Google Sheets, email, or FTP/SFTP) and blending it with online data. This allows brands to analyze their TV, offline ads, and other data alongside digital channels.

Custom connectors

A standout feature is that Improvado will build new API connectors on request if a customer needs a source that’s not already in its library. This option is available to users on all pricing plans.

This means if your team adopts a new ad platform or a client uses a lesser-known network, Improvado’s team can develop and maintain that connector for you.

Improvado also offers built-in transformation capabilities specifically oriented toward marketing use cases. Its no-code transformation framework includes AI mapping, blending, grouping, and joining data—all without code. Improvado provides multiple pre-built models and dashboards that can be implemented with just a few clicks. These include cross-channel models, paid media analytics, ecommerce models, and others. This simplifies setup and accelerates time to value for marketing teams.

In terms of data destinations, Improvado is quite flexible:

  • Improvado can load data into popular warehouses like Snowflake, BigQuery, Redshift, and others, similar to Fivetran.
  • It also provides data warehouse management services, which is especially helpful for marketing teams without dedicated IT support.
  • Improvado includes native connectors or export options for tools like Tableau, Looker, and Looker Studio.
  • You can also extract data via CSV or their API for use with other destinations if needed.

The biggest difference between the platforms is Improvado’s marketing intelligence features—including Marketing Data Governance for metric pacing, custom alerts, and campaign monitoring, and AI Agent for ad-hoc reporting, AI-generated reports, and data exploration.

  • Marketing Data Governance serves as an automated data quality and campaign monitoring system. It continuously validates data and monitors campaigns across various platforms against pre-defined rules, providing real-time alerts when deviations occur.
  • AI Agent enhances data interaction by allowing users to query their marketing data using natural language. This feature translates user questions into SQL queries, providing instant insights without the need for technical expertise. AI Agent supports the creation of customized reports, visualizations, and dashboards, facilitating a more intuitive and efficient data analysis process.
Best for

Improvado is built for mid-sized to enterprise brands and marketing agencies focused on optimizing marketing performance at scale and looking for a more complete, marketer-friendly layer on top of the data integration engine.

Improvado Pricing

Improvado provides three pricing tiers, ranging in the number of unique rows, data sync frequency, historical data sync, and other features.

  •  Improvado provides access to all connectors and allows an unlimited number of accounts per data source across all pricing plans.

Improvado Pros

  • Improvado is designed to serve marketing operations. It handles metrics, dimensions, and terminology native to marketing use cases.
  • It allows users to define custom metrics and normalize data across platforms without SQL.
  • Improvado is more than a data pipeline. It aggregates and prepares data for analysis but also automates marketing reporting with dashboard templates, performance monitoring tools, and AI insights.
  • Improvado can run marketing intelligence on top of your data warehouse so that no data is moved or replicated outside your environment.

Improvado Cons

  • Improvado is focused heavily on marketing and advertising. Not ideal for integrating product usage or operational systems outside of marketing unless combined with another tool.
  • The platform doesn't feature an embedded SQL editor or user-executable scripts. If custom logic can't be implemented with no-code transformations, clients can reach out to the Improvado Professional Services team.

2. Stitch

Stitch Data is an ETL tool used to integrate and manage data from multiple sources in a single, cloud-based platform.

Stitch is a close Fivetran alternative focused on the ETL/ELT pipeline layer rather than providing an end-to-end analytics platform. Stitch (now part of Talend) is a cloud-based ETL service designed for simplicity and cost-effectiveness.

It supports around 100+ sources officially, including common marketing ones like Google Ads, Campaign Manager, or Salesforce, and many more via community-contributed taps. However, compared to Fivetran or Improvado, Stitch has fewer native marketing connectors. The list is smaller, especially for less common services).

Custom connectors

The advantage is that because Stitch is open-source friendly if a connector doesn’t exist, your developers can potentially find a Singer tap for it or even build one. But that means relying on technical resources. Also, the depth of support for each connector might be shallower. It might not pull every single metric or breakdown available in the API by default, whereas marketing-focused platforms often do.

Stitch originally advertised itself as “ETL minus the T.” It performs no significant transformations out of the box. The philosophy is to replicate source data as-is. If you need to transform data, you do it after it’s in your warehouse using SQL or a separate tool. Stitch’s parent company, Talend, does offer heavy transformation tools, but those are separate products.  

Stitch’s UI is clean and simple, but it’s very barebones. It was designed to be a self-service tool for developers and analysts to set up data replication quickly. For a marketer, using Stitch might be slightly easier than Fivetran initially because of its simplicity, but it has similar challenges. You can click to set up connectors without coding, but once data is flowing to a warehouse, Stitch provides no analytical interface or marketing-specific aids. 

Best for

Stitch is often favored by smaller teams or those with tight budgets because it gets the job done for moving data, but it’s not as hands-off and doesn't have a reporting layer.

Stitch Pricing 

​Stitch offers a usage-based pricing model. The entry-level Standard plan starts at $100 per month, accommodating up to 5 million rows, and can scale up to 300 million rows per month. 

The Advanced and Premium plans provide higher data volume limits, additional destinations, enhanced features, and HIPAA compliance options. 

All plans include a 14-day free trial.

Stitch Pros

  • Designed for self-service. Great for smaller teams or MVP use cases.
  • Supports a wide range of community-built connectors through the Singer framework. Highly extensible for teams with developer resources.

Stitch Cons

  • Stitch has no reporting or visualization layer whatsoever. It is purely a data loader. 
  • Focused on E and L, not ETL. All transformations must be handled downstream (in dbt, SQL, or your data warehouse). Not marketer-friendly.
  • Support is email and ticket-based only, with limited assistance on implementation or strategic use cases.
  • Fewer prebuilt connectors than Fivetran, Hevo, or Improvado. Many connectors are community-supported and may lack full functionality or reliability.
  • The UI is minimal and assumes users understand data engineering basics. Not a good fit for marketers without SQL or BI experience.

3. Adverity

Adverity is a marketing data integration and analytics platform.
Schematic overview of how Adverity works

Similar to Improvado, Adverity is a more complete marketing data platform—not just a data pipeline. It helps aggregate, transform, and visualize data in one place.

The platform features an extensive library of over 600 data connectors, covering social, display, programmatic, analytics tools, mobile apps, CRMs, and even “other” categories like finance or weather data, if needed for correlation.

Adverity provides built-in transformation and data preparation capabilities via a web-based user interface with drag-and-drop workflows. It’s mostly no-code and visual, making it accessible to marketers with some training.

Adverity is flexible with destinations. It can send data to data warehouses, databases, BI tools, or file formats. However, many users leverage its internal storage and analytics capabilities.

Adverity has its own data store, where it retains ingested data and allows you to query and visualize it via its UI. This gives you a choice: you can use Adverity as the endpoint for analysis, never exporting data out, or set up exports to your own systems while still using its dashboards.

Adverity also includes default reporting applications and built-in visualization components. Users can drag and drop visualizations, set KPIs, and create interactive charts. Additionally, the platform supports features like alerts and AI-driven insights—for example, it can notify you if a KPI drops or an anomaly is detected.

Best for

Mid-to-enterprise marketing teams that need to unify and analyze data from many marketing sources with strong transformation and built-in reporting tools.

Adverity Pricing

​Adverity offers customized pricing based on factors like specific business needs, the number of data sources, data destinations, and desired features. All new users can begin with a 14-day free trial, which provides access to all Standard plan features but with a limited data row allowance. 

Adverity Pros

  • The tool is specifically designed for marketing data use cases, offering tailored workflows and metrics for marketing intelligence.
  • Adverity supports one of the largest sets of pre-built connectors.
  • Adverity provides built-in dashboards and default reporting templates. Enables marketers to analyze data directly in-platform without relying on external business intelligence tools.

Adverity Cons

  • The platform is powerful but not immediately intuitive for non-technical users. Initial setup, especially for custom metrics or multi-source harmonization, has a steep learning curve and may require expert support.
  • While solid for marketing reporting, Adverity dashboard customization is not as flexible or advanced as dedicated BI tools like Tableau or Looker.
  • Customers mention query speed noticeably slows as the data volume grows, affecting productivity when working with historical analysis across multiple marketing channels.

4. Hevo Data 

Hevo Data is an ETL tool alternative to Fivetran.

Similar to Stitch, Hevo Data is a Fivetran alternative focused on the ETL/ELT pipeline layer.

Hevo is a general ETL tool and supports 150+ data sources, including many popular marketing tools. Still, it’s fair to say Hevo is oriented toward the most commonly used sources, niche marketing platforms might not be supported.

Custom connectors

Hevo Data provides a REST API connector that allows you to pull data from any API by specifying the URL and authentication. It also supports webhook-based ingestion, enabling you to push data from an app into Hevo. These options make it possible for technically savvy users to set up custom integrations.

One notable difference between Fivetran and Hevo Data is Hevo’s inclusion of built-in transformation capabilities, both preload and postload. Hevo offers a drag-and-drop transformation interface and integrates with dbt for users who want to build more advanced transformations.

Like Fivetran and Stitch, Hevo supports numerous destinations, mostly databases and data warehouses. The website also lists some analytics tools as supported destinations. Essentially, Hevo can load data into applications that accept API-based inputs, but its primary use is to load data into a database or warehouse where it can be analyzed with BI tools.

Similar to Fivetran, Hevo focuses on pipelines and does not include a reporting or dashboard layer.

However, in some contexts, Hevo supports Reverse ETL by enabling destination-to-source sync on select connectors—extending its use beyond traditional one-way data flows.

Best for

Small to mid-sized teams looking for a no-code, fully managed data pipeline platform to quickly integrate popular SaaS and database sources into cloud data warehouses with minimal setup and engineering effort.

Hevo Data Pricing 

​Hevo Data employs an event-based pricing model, where costs are determined by the number of data events, such as inserts, updates, or deletions, processed each month. 

The platform offers a Free plan, allowing up to 1 million events per month, suitable for small-scale data needs. All plans come with a 14-day free trial, enabling users to assess the platform's suitability before committing. ​

Hevo Data Pros

  • Hevo has a user-friendly drag-and-drop transformation builder.
  • The learning curve for Hevo is generally low, users often get up and running in hours.
  • Hevo covers popular marketing sources and offers generic connectors, making it a solid middle ground between marketing-specific tools like Improvado and general-purpose platforms like Fivetran.

Hevo Data Cons

  • The tool has data volume and performance limitations that can hinder scalability for large datasets.
  • When integrating with new tools or adapting to schema changes, users often need to perform manual mappings.
  • Hevo's library of connectors is relatively small, especially for less common data sources, which may necessitate custom development or alternative solutions.
  • Troubleshooting issues can be difficult due to unclear error messages and a lack of detailed logs.

5. Airbyte 

Airbyte is a Fivetran alternative, data integration platform.

Airbyte is an open-source data integration platform. Similar to Fivetran, its core function is ELT (extract and load), meaning it replicates data from sources to destinations.

Airbyte now lists over 550 connectors in its marketplace, including both official and community-supported options. Users can modify existing connectors or build their own.

Custom connectors

One key difference between Airbyte and other platforms on this list is that Airbyte classifies connectors by maturity: some are Airbyte Certified, while many are in Beta or Alpha stages. In fact, a large portion of Airbyte’s connectors, especially newer or less common marketing sources, may be marked Alpha/Beta, meaning they are community-contributed or not extensively tested.

Airbyte provides a Normalization feature, which is essentially a post-load transformation using SQL. For more advanced transformations, Airbyte does not offer its own UI or tooling. Instead, it expects you to use dbt or write custom SQL.

There is no no-code visual transformation builder in Airbyte. All transformations are code-based (SQL or Python) and external to Airbyte’s core platform.

Another notable feature is that Airbyte can be self-hosted—you can run an Airbyte server on your own machine or in the cloud. This can be beneficial for organizations in industries where secure data processing, compliance, and infrastructure control are critical.

Best for

Airbyte offers greater control and flexibility, making it a strong option for organizations with engineering resources and custom data requirements.

Airbyte Pricing 

Airbyte offers self-hosted and cloud-based deployment options, each with distinct pricing structures:

  • The self-hosted version is open-source and free to use. While there are no licensing fees, users are responsible for managing their own hosting environments, which may involve costs related to servers, storage, and maintenance.​
  • The cloud-based version, known as Airbyte Cloud, is a fully managed service. It operates on a usage-based pricing model, where costs are determined by factors such as data volume and the number of pipelines. 

Airbyte Pros

  • Airbyte can be deployed on-premises, giving full control over security, compliance, and data residency—ideal for teams with strict governance requirements.
  • Lets users create or customize connectors using a low-code builder or SDK, ideal for niche or proprietary sources.
  • Volume-based pricing that can be significantly cheaper than Fivetran’s MAR model. 

Airbyte Cons

  • Airbyte is primarily designed as a data integration tool for engineers and data teams. It lacks marketer-friendly features like pre-built dashboards, report templates, or intuitive UI workflows tailored to campaign performance or attribution.
  • Initial setup and ongoing maintenance (updates, scaling, backups) can be complex and time-consuming without dedicated DevOps or data engineering support. Even with Airbyte Cloud, configuring and managing pipelines often requires engineering knowledge. 
  • Many connectors are in beta/alpha stages and community-maintained. Production reliability may vary depending on the connector and may require debugging.
  • Unlike platforms built specifically for marketing, Airbyte doesn't automatically unify naming conventions, campaign structures, or metrics across ad platforms—this must be done manually in a downstream tool.
