Apache Superset™ As A Looker Alternative
Open Source as in Freedom
In June 2019, the Looker team announced that they were being acquired by Google .
This isn’t a new phenomenon. Given how mature and dynamic the BI market is, consolidation has been accelerating over the past few years:
- Redash was acquired by Databricks
- Chart.io was acquired and shut down by Atlassian
- Tableau was acquired by Salesforce
- Periscope was acquired by Sisense
- Zoomdata was acquired by Logi Analytics
While consolidation is likely to continue, these concerns don’t arise when your BI platform is open source. Whether you're using a commercial vendor or self-hosting, you have immense flexibility with open source.
Superset vs Looker
Apache Superset is the most popular and mature open-source business intelligence platform out there. In this post, I'll make the case for why Superset is the most compelling alternative to Looker.
No-code Query Builder
| Feature | Looker | Superset |
|---|---|---|
| Support common SQL operations (Select, Filter, GroupBy, etc) | ✅ | ✅ |
| Preview visualization during iteration | ✅ | ✅ |
| Preview generated SQL query during iteration | ✅ | ✅ |
| View data transformation results as a table | ✅ | ✅ |
| Use virtual datasets to build charts | ✅ | ✅ |
| Ability to join tables | ✅ | ➕ In Development |
Both Looker and Superset have no-code interfaces for crafting SQL queries.
Rich Set of Visualizations
| Feature | Looker | Superset |
|---|---|---|
| Common charts (pie, line, bar, etc) | ✅ | ✅ |
| Funnel visualizations | ✅ | ✅ |
| Sankey diagrams | ✅ ( for $10,000 ) | ✅ |
| Network visualization | ❌ | ✅ |
| Ability to add custom charts / visualizations | ✅ | ✅ |
| Number of default charts | 20 | 40 (and growing 📈) |
| Number of geospatial visualizations | 7 | 10 |
Looker has a limited set of chart types (approximately 20). Superset ships with more than 60 charts and this list is quickly growing). More importantly, Superset lets you develop and add new custom visualizations.
Advanced SQL Editor
| Feature | Looker | Superset |
|---|---|---|
| Export query results as CSV | ✅ | ✅ |
| Database metadata explorer | ✅ | ✅ |
| Linting and auto-complete | ✅ | ✅ |
| Multi-tab workflow | ✅ | ✅ |
| Save query for re-use | ✅ | ✅ |
| Semantic layer: save queries as virtual datasets | ✅ | ✅ |
| Semantic layer: define custom metrics | ✅ | ✅ |
| Semantic layer: calculated columns | ✅ | ✅ |
Both Looker and Superset ship with a powerful SQL editor and a powerful semantic layer.
- Aggregate values across multiple columns and publish as Metrics.
- Metrics can be certified as authoritative by a specific user.
- Transform specific columns and publish as Calculated Columns.
- Write arbitrary SQL queries and publish as a Virtual Dataset.
In the no-code chart builder (Explore), metrics, columns, and virtual datasets all inherit the power that physical database tables have in Superset.
| Feature | Looker | Superset |
|---|---|---|
| Basic datetime, value, and range filters | ✅ | ✅ |
| Dashboard templating | ✅ | ✅ |
| Custom theming | ✅ | ✅ |
| Dashboard can contain charts from multiple data sources | ✅ | ✅ |
| Cross-filtering | ✅ | ✅ |
Superset is widely known for the beautiful charts and dashboards you can create quickly. Here's an example that's a community favorite:
Enterprise Features
| Feature | Looker | Superset |
|---|---|---|
| SSO (single sign-on) | ✅ | ✅ |
| Usage and audit logs | ✅ | ✅ |
| Admin API | ✅ | ✅ |
| Row level security | ✅ | ✅ |
| Chart or dashboard level permissioning | ✅ | ✅ |
| Workspace level RBAC (role-based access control) | ✅ | ✅ |
| Viewer-only mode | ✅ | ✅ |
| SaaS Cloud option | ✅ | ✅ |
| Self-hosted / On-prem deployment | ✅ | ✅ |
Superset was developed with the following constraints in mind, which enable the features above:
- modern languages (Python, TypeScript, & ReactJS) and modern UX (web-based)
- scalable (incubated at Airbnb, designed to scale with cloud-native best practices )
- API should support and mirror what can be done in the UI
- highly customizable (open source!)
We are proud that Superset is competitive with Looker on the key fronts that enterprises require!
