I am very satisfied with QuerySurge, as it serves as our primary tool for file-to-file and database-to-database comparisons. I rely on it to verify results and provide signoffs, and overall, I am happy with its performance. I particularly appreciate the Data Staging options that QuerySurge offers, as they seem to work very well for my needs. Additionally, the initial setup was very easy, making the transition to QuerySurge smooth and hassle-free. Review collected by and hosted on G2.com. What do you dislike about QuerySurge? I find the performance of QuerySurge to be a significant challenge, especially when processing large datasets. Executing comparisons on more than 500,000 records can take over 30 minutes, and in the case of 5 million records, it takes roughly an hour. This impacts efficiency and I believe there’s room for improvement in processing speeds. Additionally, the tool doesn't provide detailed record-wise results for past queries, only showing percentages of pass and failure, which limits insight depth. When errors occur due to incorrectly mentioned fields in a query, QuerySurge does not offer specific guidance or suggested modifications, which can hinder troubleshooting efforts.

I use QuerySurge for ETL testing and file/database comparisons, which is crucial for our result verification and signoffs. It handles larger data volumes better than our previous tool, Beyond Compare, though performance on large datasets could improve. Review collected by and hosted on G2.com.

We’re glad to hear that the Data Staging capabilities, ease of setup, and overall reliability have supported your ETL testing and verification workflows. It’s great to know QuerySurge has been an improvement over your previous comparison tools. We also appreciate your candid notes on performance with very large datasets and on the level of detail available in historical results. Both areas are active parts of our roadmap. We continue to enhance parallel processing, result retrieval, and error-handling clarity to help users move through high-volume testing more efficiently and with deeper visibility into record-level differences. Thank you again for taking the time to share your experience. Your input helps us refine QuerySurge, and we’re here to support you if you’d like to walk through performance tuning options or discuss upcoming improvements.

FN Fernando N. Especialista em testes 11/24/2025 "Versatile Data Validation with Ease" 4.5/5 What do you like best about QuerySurge? I find QuerySurge invaluable for QA validation due to its ability to effectively compare large amounts of data. Its user-friendly interface significantly aids in reporting and identifying differences between source and target datasets, making this process more efficient and less error-prone. I appreciate how easy it is to use, getting the job done without unnecessary complications. The software's capability to connect to multiple types of data sources—such as SQL, on-premises, cloud systems, and even using data files—adds tremendous value to its functionality. I also benefit greatly from its own API, which allows for dynamic interactions like changing snippet values and initiating scenarios, making it adaptable and versatile across different use cases. Additionally, its integration with other tools through API requests enhances our workflow, ensuring we can continue to leverage existing systems while making the most of QuerySurge's robust features. Review collected by and hosted on G2.com. What do you dislike about QuerySurge? I find the current use of snippets in QuerySurge somewhat static and believe they could be more dynamic. It would be beneficial if snippets had the capability to store queries and other types of code to retrieve values from external sources. This would allow for more flexible use rather than just being a static piece of code or information to be combined within queries or XML. Review collected by and hosted on G2.com.
