Airflow and dbt Pricing: What Open Source Analytics Tools Really Cost

Organizations often opt for open-source tools because "free" seems like an easy decision, especially compared to the higher price of managed versions of the same tooling. However, as with many things, there is no such thing as a free lunch. When choosing these open-source tools, it is easy to say that the Airflow and dbt pricing is $0 dollars meaning a cost-saving choice, but hidden expenses that are hard to ignore will quickly be revealed.

dbt Core and Apache Airflow are a natural pair in modern data analytics. dbt Core simplifies SQL-based data transformations, empowering data teams to create and maintain clean, well-documented, structured pipelines. Apache Airflow takes care of orchestrating these workflows, automating the movement and processing of data through the data engineering life cycle. Together, they can drive a powerful analytics stack that’s flexible and scalable—when used correctly. But this flexibility often comes at a price.  

In this article, we’ll examine the build vs. buy dilemma, highlighting the flexibility and true costs of open-source tools like dbt Core and Apache Airflow. We’ll also compare them to managed solutions such as dbt Cloud pricing and Datacoves pricing, providing the insights you need to evaluate the trade-offs and choose the best option for your organization.  

dbt and Airflow pricing

Open-source dbt pricing

The open-source tool dbt is free to download and use. However, the actual cost emerges when considering the technical resources required for effective implementation and management. Tasks such as setting up infrastructure, ensuring scalability, and maintaining the tool demand skilled engineers.

Assuming a team of 2–4 engineers is responsible for these tasks, with annual salaries ranging from $120,000 to $160,000 (approximately $10,000 to $13,000 per month), even dedicating 25–50% of their time to managing dbt Core results in a monthly cost of $5,000 to $26,000. As your use of dbt scales, you may need to hire a dedicated team to manage the open-source solution full-time, leading to costs equating to 100% of their combined salaries.

So we can begin to see the true open source dbt pricing, especially at scale. In addition to engineering labor are other costs such as time, and effort required to maintain and scale the platform. More on that later.

dbt Cloud Pricing

Just on engineering pricing alone, we begin to see the comparison between the open-source and managed solutions. dbt Labs offers a hosted solution, dbt Cloud, with added features and tiered pricing options.

• Developer Plan: Best for individual users, this free tier includes a single developer seat, up to 3,000 models built per month, and support for one dbt project.

• Team Plan: Aimed at small to mid-sized teams, this plan supports up to 8 developer seats, one dbt project, and 15,000 models built per month. Priced at $100/user/month, additional model builds cost $0.01 per model.

• Enterprise Plan: (This is the plan that most medium and large organizations will need) Designed for larger organizations, this tier supports unlimited users and projects. The MSRP jumps to a whopping $4,800 per seat and a fixed number of model runs after which the $0.01 per model price also applies.

Opting for a managed solution will allow your organization to cut engineering costs down or allow your engineers to focus on other projects. However, while dbt Cloud reduced the infrastructure burden a bit, it only focuses on the T of ELT. Meaning, you still need engineers to manage the other pieces of the stack which can result in a disconnected data pipeline.

Open-source Airflow

It is worth noting that some companies decide to use dbt cloud for the scheduler feature which can quickly become limiting as workflows become more complex. The next step is always a full fledged orchestrator such as Airflow.

Just like dbt Core, Apache Airflow is also free to use, but the true cost comes from deploying and maintaining it securely and at scale, which requires significant expertise, particularly in areas like Kubernetes, dependency management, and high-availability configurations.

Assuming 2–4 engineers with annual salaries between $130,000 and $170,000 (around $11,000 to $14,000 per month) dedicate 25–50% of their time to Airflow, the monthly cost ranges from $5,500 to $28,000. The pattern we saw with dbt Core rings true here as well. As your workflows grow, hiring a dedicated team to manage Airflow becomes necessary, leading to costs equating to 100% of their salaries.

Managed Airflow from AWS, MWAA

For teams looking to sidestep the complexities of managing Airflow in-house, managed solutions provide an appealing alternative:

• AWS Managed Workflows for Apache Airflow (MWAA): A managed Airflow service from Amazon, MWAA simplifies deployment and scaling but has variable pricing based on environment size and execution time, which can make costs unpredictable.

• Other Providers: Options like Astronomer and Google Cloud Composer offer similar managed Airflow solutions, each with unique features, performance considerations, and pricing structures.

A managed Airflow solution typically costs between $5,000 and $15,000 per year, depending on workload, resource requirements, and the number of Airflow instances. By choosing a managed solution, organizations can see cost savings in the infrastructure maintenance, overall maintenance stress and more.

The hidden costs of open-source tools

Setting up and managing infrastructure for Airflow and dbt Core isn’t as straightforward—or as “free”—as it might seem. The day-to-day work from managing Python virtual environments, keeping dependencies in check, and tackling scaling challenges require ongoing expertise and attention. In addition to salaries and benefits, what starts as an open-source experiment can quickly morph into a significant operational overhead full of hidden costs. Let’s dive into how by looking at time and expertise, security and compliance, and scaling complexities which, if not considered, can lead to possible side effects such as extended downtime, security issues and more.

Time and expertise

The time it takes to configure, customize, and maintain a complex open-source solution is often underestimated. It’s not until your team is deep in the weeds—resolving issues, figuring out integrations, and troubleshooting configurations—that the actual costs start to surface. With each passing day your ROI is threatened. You want to start gathering insights from your data as soon as possible. Datacoves helped Johnson and Johnson set up their data stack in weeks

And then there’s the learning curve. Not all engineers on your team will be senior, and turnover is inevitable. New hires will need time to get up to speed before they can contribute effectively. This is the human side of technology: while the tools themselves might move fast, people don’t. That ramp-up period, filled with training and trial-and-error, represents yet another hidden cost.

Security and compliance

Security and compliance add another layer of complexity. With open-source tools, your team is responsible for implementing best practices—like securely managing sensitive credentials with a solution like AWS Secrets Manager. Unlike managed solutions, these features don’t come prepackaged and need to be built integrated with the system.

Compliance is no different. Ensuring your solution meets enterprise governance requirements takes time, research, and careful implementation. It’s a process of iteration and refinement, and every hour spent here is another hidden cost as well as risking security if not done correctly.

Scaling complexities

Scaling open-source tools is where things often get complicated. Beyond everything already mentioned, your team will need to ensure the solution can handle growth. For many organizations, this means deploying on Kubernetes. But with Kubernetes comes steep learning curves and operational challenges. Making sure you always have a knowledgeable engineer available to handle unexpected issues and downtimes can become a challenge. Extended downtime due to this is a hidden cost since business user are impacted as they become reliant on your insights.  

Comparing build vs. buy: Key tradeoffs

Throughout this article, we have uncovered the true costs of open-source tools, bringing us to the critical decision between building in-house or buying a managed solution. Even after we have uncovered the actual cost of open-source, the decision isn’t just about price—it’s also about flexibility a custom build offers.

Managed solutions often adopt a one-size-fits-all approach designed to attract the widest range of customers. While this can simplify implementation for many organizations, it may not always meet the specific needs of your team. To make an informed decision, let’s examine the key advantages and challenges of each approach.

Building In-House

Pros:

• Customization: The biggest advantage of building in-house is the flexibility to customize the tool to fit your exact use case. You maintain full control, allowing you to align configurations with your organization’s unique needs. However, with great power comes great responsibility—your team must have a deep understanding of the tools, their options, and best practices.

• Control: Owning the entire stack gives your team the ability to integrate deeply with existing systems and workflows, ensuring seamless operation within your ecosystem.

• Cost Perception: Without licensing fees, building in-house may initially appear more cost-effective, particularly for smaller-scale deployments.

Cons:

• High Upfront Investment: Setting up infrastructure requires a significant time commitment from developers. Tasks like configuring environments, integrating tools like Git or S3 for Airflow DAG syncing, and debugging can consume weeks of developer hours.

• Operational Complexity: Ongoing maintenance—such as managing dependencies, handling upgrades, and ensuring reliability—can be overwhelming, especially as the system grows in complexity.

• Skill Gaps: Many teams underestimate the level of expertise needed to manage Kubernetes clusters, Python virtual environments, and secure credential storage systems like AWS Secrets Manager.

Example:
A team building Airflow in-house may spend weeks configuring a Kubernetes-backed deployment, managing Python dependencies, and setting up DAG synchronizing files via S3 or Git. While the outcome can be tailored to their needs, the time and expertise required represent a significant investment.

Buying a managed solution

Pros:

• Faster Time to Value: With a managed solution, your team can get up and running quickly without spending weeks—or months—on setup and configuration.

• Reduced Operational Overhead: Managed providers handle infrastructure, maintenance, and upgrades, freeing your team to focus on business objectives rather than operational minutiae.

• Predictable Costs: Managed solutions typically come with transparent pricing models, which can make budgeting simpler compared to the variable costs of in-house built tooling.

Cons:

• Potentially Less Flexibility: Managed solutions may not allow for the same level of customization as building in-house, which could limit certain niche use cases.

• Dependency on a Vendor: Relying on a vendor for your analytics stack introduces some level of risk, such as service disruptions or limited migration paths if you decide to switch providers.

Example:

Using a solution like MWAA, teams can leverage managed Airflow eliminating the need for infrastructure worries however it may not have the flexibility or interoperability with other aspects of their stack

Whereas using a solution like Datacoves, teams can leverage managed Airflow and pre-configured environments for dbt Core. This eliminates the need for infrastructure setup, simplifies day-to-day operations, and allows teams to focus on deriving value from their analytics, not maintaining the tools that support them.  

Verdict on build vs buy

There is no universal right answer to the build vs. buy dilemma—every use case is unique. However, it’s important to recognize that many problems have already been solved. Unless there is a compelling reason to reinvent the wheel, leveraging existing solutions can save time, money, and effort.

In Fundamentals of Data Engineering, Joe Reis and Matt Housley emphasize the importance of focusing on delivering insights rather than getting entangled in the complexities of building and maintaining data infrastructure. They advocate for using existing solutions wherever possible to streamline processes and allow teams to concentrate on extracting value from data. The key question to ask is: Will building this solution provide your organization with a competitive edge? If the answer is no, it’s worth seeking out an existing solution that fits your needs. Managed platforms can reduce the need for dedicated personnel as we saw above and provide predictable costs, making them an attractive option for many teams.

This philosophy underpins why we built Datacoves. We believe data teams shouldn’t be bogged down by the operational complexities of tools like dbt and Airflow. And we also believe that Data teams should have access to the flexibility a custom-built solution has to offer. Datacoves offers the flexibility these tools are known for while removing the infrastructure burden, enabling your team to focus on what really matters: generating actionable insights that drive your organization forward.
