You may be here because you’re actively shopping for a data catalog, because you’re beginning your documentation and governance journey, or simply because you’re really into data and technology (hey, we respect that - we are too!).
CastorDoc and Atlan are two popular data catalogs in the market, so you may be wondering: how do they stack up? In this article, we’ll give a detailed comparison of the two platforms by looking at their key features, technology integrations, target audience, pricing, ratings, and ease of use.
Whether you're an analyst, a data scientist, or a business user, this comparison will give you a comprehensive understanding of what each data catalog has to offer and will help you make an informed decision.
Let’s start with the basics. If you’re wondering what a data catalog IS, we’ve got you covered. Here’s a brief explanation, according to Gartner:
“A data catalog creates and maintains an inventory of data assets through the discovery, description, and organization of distributed datasets. The data catalog provides context to enable data stewards, data/business analysts, data engineers, data scientists and other data consumers to find and understand relevant datasets for the purpose of extracting business value.”

Data catalogs play a crucial role in managing and organizing large datasets for organizations. In recent years, there has been a growing demand for data discovery to help companies find, understand, and use their data across ever-increasing data platforms and systems. And as you think about your data catalog needs, there’s a wide data catalog landscape to choose from, and vendor comparisons can help you make the right choice based on your organization’s needs.
We have kept our process as unbiased as possible. Our approach analyzed Atlan vs CastorDoc's offerings, paired with reputable customer and third-party review websites such as G2 and Gartner. We evaluated six key factors to help you make an informed decision:
Let’s get started!
CastorDoc was established by former data scientists, engineers, and heads of data to help companies improve the data experience.

Therefore, companies can drive efficiency and ROI by saving data engineers’ time, deprecating unused data, improving data health, and making higher-quality business decisions. Ultimately, CastorDoc allows companies to optimize their data stack by unifying metadata from all of their preferred tools into one cohesive system - without the chaos.
Atlan was founded in Singapore in 2018 by Varun Banka and Prukalpa Sankar. It is known to provide different experiences for different users. Each user is given a custom experience, including their homepage and metadata, which is curated based on their workflows.

CastorDoc was built for viral, company-wide adoption. While its main users are data people – such as Data Analysts, Data Scientists, Data Stewards, Data Engineers, and Heads of Data – it is also intentionally designed to be used by Business, Operations, Support, Finance, and Management teams who are looking to make decisions based on real-time data.
Atlan was built by data people for data people. It is used by Data Engineers, Data Analysts, Data Scientists, and Heads of Data. While it provides support for business roles as well, data team members are its sweet spot.

Ease of Use
CastorDoc differentiates itself in the world of data catalog systems by its user experience and ease of use. The company was created because the founders had worked with traditional data catalogs, and found them clunky, outdated, and difficult to manage.
CastorDoc’s goal is to make working with data easy. It’s built in a way that anyone – regardless of their data literacy level, department, or technical prowess – can find and trust the data. It features a “Google-like” search engine, which allows any user to quickly find what they need, no technical expertise required. CastorDoc can be set up within 30 minutes and will provide value on Day 1.
Atlan is also highly rated for its ease of use. The platform is designed with a sleek and intuitive interface, search and discovery features, and a collaborative environment for data teams. It simplifies data discovery and governance, while offering intuitive navigation, customizable dashboards, and collaboration tools like comments and annotations to help teams work more effectively.
Atlan is built for data teams and does require a higher data literacy level to understand, as its engineering-oriented features add complexity to the experience. For example, one way to query data in Atlan requires SQL, which business users may not be familiar with. Therefore, non-data users may need to work through data teams to get the information they need.
Because of this, CastorDoc has better usability for the whole business. Its intuitive UX was purpose-built for viral adoption, which you can easily see in their short demo video.
Review and Ratings
In writing this article, we consulted both CastorDoc and Atlan reviews from sites like G2. You can review the CastorDoc ratings here, and the Atlan ratings here. These links also include product reviews. Overall, both companies rated well and had positive reviews. However, CastorDoc was rated higher in the three main categories - Ease of Use, Quality of Support, and Ease of Setup.
G2 highlights Ease of Use as the top factor that impacts user satisfaction for Machine Learning Data Catalog products. It rates CastorDoc as a 10/10 for ease of use, and Atlan as an 8.5/10. As one CastorDoc reviewer notes,
“CastorDoc is super easy to use! We love that it auto-populates definitions for commonly used tables (zendesk, salesforce, etc.). We also love that it tells us which tables are most popular - super helpful when we were just starting to populate our data dictionary, and that it syncs with tools like dbt and looker. Our #1 most favorite part is the lineage tool - it has been incredibly timesaving for us when making logic updates and changes to understand the downstream impact of said changes.”
For Quality of Support, CastorDoc ranks 9.7/10 and Atlan ranks 8.6/10. It’s worth noting that the average is 8.6/10, so CastorDoc outranked both Atlan and the average score across this category.

The Best Data Catalog for Your Business
When looking at all of the factors discussed, including available integrations, key audience, ease of use, reviews and ratings, and service and support, the winner is CastorDoc.
While both companies offer similar integrations and are regularly adding more, the real differentiator when looking at CastorDoc compared to Atlan is the key audience for each product and its ease of use. CastorDoc ranks higher for ease of use, which makes sense as the solution was built for non-data people to be able to use. In addition, CastorDoc ranks significantly higher in Quality of Support.
Atlan certainly has great features, but CastorDoc is the #1 platform for data lineage and ease of use for the whole organization.
Fantastic tool for data discovery and documentation
“[I like] The easy to use interface and the speed of finding the relevant assets that you're looking for in your database. I also really enjoy the score given to each table, [which] lets you prioritize the results of your queries by how often certain data is used.”
