Great Expectations vs QuerySurge

Great Expectations (GX) is a framework for defining data tests and checking whether data meets their criteria. GX Core is a Python library for building and running data-validation workflows, and it requires Python versions 3.10 through 3.13. GX Cloud provides a web interface for data teams, including technical and nontechnical stakeholders, and runs tests in the environment where connected data resides using read-only connections. Data Docs turns Expectations, validation results, and related metadata into static web pages. GX lists data-source integrations including Databricks, BigQuery, Pandas, PostgreSQL, Snowflake, Spark, Redshift, and cloud storage services. Notification integrations include Slack, Email, PagerDuty, OpsGenie, and Microsoft Teams; orchestration integrations include Apache Airflow, Dagster, and Prefect. Custom rules can be written with SQL in GX Cloud or through GX Core. The Developer plan costs nothing and covers up to five data assets under test per month and three users, with unlimited rows per asset. Team and Enterprise have custom data-asset limits and no listed prices.

QuerySurge is an AI-powered data quality platform for automating validation across an organization's data ecosystem, from extract and transform work through loading and reporting. It compares data between sources, targets and reports without manual SQL, and its AI can generate tests from mapping documents. The company lists more than 200 data-store connections, including Databricks, Snowflake, Microsoft Fabric, Oracle, Redshift, BigQuery, MongoDB, Power BI and Tableau. REST API validation supports CI/CD workflows, with integrations such as Jenkins, GitLab and Azure DevOps; test management connections include Jira, OpenText ALM and IBM Engineering Test Management. Deployment can be on bare-metal servers or virtual machines on premises or in a private cloud, with pay-as-you-go options in Azure and AWS. Trial choices are a 1-day hosted cloud trial for one user and a 15-day download trial for two users. The download trial lists Windows, Red Hat or Fedora, with minimum requirements of 16 GB RAM and 100 GB available disk space. Pricing note: From $514/user; no free plan is listed.
