Redash vs Yandex DataLens

Redash is an open-source, self-hosted web platform for querying data, creating visualizations, building interactive dashboards, and sharing results within an organization. Its query editor offers schema browsing, autocomplete, keyboard shortcuts, and reusable snippets. Users can connect sources such as Amazon Athena, BigQuery, PostgreSQL, Snowflake, MongoDB, Google Analytics, Google Spreadsheets, JIRA, and Salesforce, then combine results in dashboards shared by URL or embedded as widgets. Visualization options include charts, cohort views, pivot tables, boxplots, maps, counters, sankey diagrams, sunbursts, and word clouds. Result updates can be scheduled, and alerts can be set for data events. Redash provides a REST API with user or query keys that can be limited to query results. Authentication options include password login, Google OAuth, and SAML 2.0. Deployment documentation covers Linux with Docker and Docker Compose. The hosted app.redash.io service shut down effective November 30, 2021.

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.
