Yandex DataLens is a web-based business analytics tool for visualizing data, building dashboards, and producing reports. Its interactive dashboards can refresh on a schedule or be embedded, while reports can be generated as print-ready multipage documents. Users can build charts with a self-service visualization builder or customize them with JavaScript. Neuroanalyst supports data analysis and visualization creation. Connections include databases such as ClickHouse, PostgreSQL, MySQL, YDB, Greenplum, SQL Server, Oracle, StarRocks, Trino, and Snowflake, alongside sources such as Google Sheets, Prometheus, Yandex Metrica, AppMetrica, and files. Corporate accounts can use SSO or Yandex ID, with permissions for groups and individuals; row-level security can restrict access within a dataset. A Free plan costs nothing for one seat. Each viewer or editor needs a seat, and teams are billed by seat. New customers receive 15 days of free team access, extendable by another 15 days when a billing account is linked before the initial trial ends. External databases must use certificates signed by a certificate authority; self-signed certificates are not supported.
