"Efficient Data Comparison, Needs Refinement"
4/5
What do you like best about QuerySurge?

I really appreciate how QuerySurge facilitates the easy comparison of table data based on query pairs, allowing me to identify differences across various scenarios with efficiency. The ability to store scenarios that can be reused with different data connections is incredibly valuable for our regression suites, as it streamlines the process of running QA tests for each release. Once set up, I can effortlessly trigger these scenarios using specific database connections and have the results ready for review within just 10-20 minutes. Additionally, the capability to export the analysis into Excel is a major advantage, as it enables sharing detailed results with colleagues who might require a deeper dive into the data. Furthermore, the integration with Jenkins script for automating scenario triggers ensures flexible and time-efficient operations, especially for after-hours testing. Although I wasn't part of the initial setup team, my experience with updating QuerySurge to a new version was smooth, indicating the software is user-friendly in terms of maintenance and updates.

What do you dislike about QuerySurge?

Sometimes the analysis in QuerySurge creates false failures, such as when only one column in the table data is different, but multiple columns are highlighted as differences. This leads to confusion and false alerts. Additionally, when data are exactly the same and should match perfectly, they are occasionally incorrectly highlighted as discrepancies. This requires testers to manually scan rows or export data to Excel to apply formulas and verify that no true differences are being overlooked. Review collected by and hosted on G2.com.

"QuerySurge Makes Large-Scale Data Validation Simple and Efficient"
5/5
What do you like best about QuerySurge?

QuerySurge is purpose-built for data testing, making large-scale source-to-target validation simple and efficient. Review collected by and hosted on G2.com.

What do you dislike about QuerySurge?

QuerySurge can be expensive, especially for smaller teams, and licensing isn’t very flexible. There’s also a learning curve for new users, and advanced setups often require strong SQL and tool-specific knowledge. Review collected by and hosted on G2.com.

Response from Bill Hayduk of QuerySurge

Hi Ede,

Thank you for the detailed feedback. We’re glad to hear that QuerySurge is delivering on its core purpose by making large-scale source-to-target validation straightforward and efficient, and helping you catch data issues early to support trusted analytics.

We appreciate your candid comments on pricing and flexibility. We understand that needs can vary widely across teams, and we do offer different licensing options, including fixed and unlimited user models, as well as enterprise configurations and pay-as-you-go in the cloud. That said, your feedback is valuable as we continue to evaluate how we can better support smaller teams.

On the learning curve, you’re right that more advanced use cases can require stronger SQL and product familiarity. We’re continuing to invest in ease-of-use features, low-code/no-code features, more self-paced training, and capabilities like our AI-driven test creation to reduce that barrier and help users ramp up more quickly.

Thanks again for sharing your experience and for highlighting both the strengths and areas where we can improve.

Regards,

Bill Hayduk

"A Must-Have Tool for Data QA and ETL Validation"
4/5
What do you like best about QuerySurge?

The thing I like most about QuerySurge is how visible and transparent it makes data issues. The pass/fail summaries, drill-down comparison views, and analytics give me immediate insight into where discrepancies are happening and why. Review collected by and hosted on G2.com.

What do you dislike about QuerySurge?

What I dislike about QuerySurge is that the user interface can feel overwhelming for new users, especially those who aren't strong in SQL. The learning curve is steeper than expected, and setting up more advanced test scenarios often requires deeper technical knowledge. Some operations feel slower when working with very large projects. Review collected by and hosted on G2.com.

Response from Bill Hayduk of QuerySurge

Hi Gyanendra,

Thank you for taking the time to share your experience with QuerySurge. We’re glad to hear that the pass/fail summaries, detailed comparison views, and analytics are giving you the visibility you need to pinpoint data discrepancies quickly.

What do you like best about QuerySurge?

Most helpful as it validates high volume of records with high speed and accuracy. It supports comparison of multilanguage data in the tables. Review collected by and hosted on G2.com.

What do you dislike about QuerySurge?

Connectivity to Snowflake DB is a tedious process and has multiple steps to get the connection established when its Single Sign on authentication. If online Chat bot support is provided it will be much helpful or at least the support team gets over call during establishment of DB connection. Review collected by and hosted on G2.com.

Response from Bill Hayduk of QuerySurge

Thanks for the positive review, Damodaran! We'll work on improving that Snowflake connection.
