"Transforms Data with Real-Time Insights"
4.5/5
What do you like best about Looker?

The reports interface for both standard and self-service reports is intuitive, straightforward, and easy to use. By using formulas based on existing data elements, users can create new fields and calculate new values as needed. It also offers a variety of attractive graph and chart formats, lets you track metrics in real time with consistent and frequent updates, and enables you to receive email reports and notifications regarding metrics. Review collected by and hosted on G2.com.

What do you dislike about Looker?

It can be a bit complex sometimes for beginners, and certain reports take time to load. For beginners, Looker could improve the onboarding experience with simpler tutorials, guided dashboard creations, and more beginner-friendly explanations for advanced features.

"Centralized LookML and real-time data: consistent definitions for the entire organization"
4.5/5
What do you like best about Looker?

What I highlight most about Looker is its centralized data model with LookML, which allows defining metrics and business logic once so that everyone in the organization works with the same definitions, avoiding inconsistencies between reports. I also value that it queries data in real-time directly from the data warehouse (without the need to extract or duplicate data), and that the visualizations and dashboards are easy to share and embed in other applications. Additionally, by versioning the models with Git, it facilitates collaborative work and change control. Review collected by and hosted on G2.com.

What do you dislike about Looker?

What I like least about Looker is the learning curve of LookML: learning its syntax and data modeling logic takes time, especially for users without prior experience in modeling or SQL. I also notice that the customization of visualizations is more limited compared to other BI tools, and that performance can be affected in complex queries over large volumes of data if the model is not well optimized. Additionally, being a 100% cloud-based tool and dependent on the data warehouse, any slowness in the underlying database directly impacts the experience within Looker.

"Rich Data & Reports with a Highly Customizable, Developer-Friendly UI"
4.5/5
What do you like best about Looker?

A lot of data. In Looker, we have so much data and reports. For our developers, adding more fields is quite easy, so we are very happy with this. UI is good, you can customize a lot of things. Review collected by and hosted on G2.com.

What do you dislike about Looker?

Sometimes, when you have too much data, it takes ages to update the page. Onboarding new users isn't easy because there are too many fields (in our case), but I think it is a common issue with these tools. Review collected by and hosted on G2.com.

I use Looker for business reporting, dashboard creation, and tracking company performance data in real-time. It helps analyze sales, operations, and customer insights all in one place, making decision-making faster and more efficient.

Review collected by and hosted on G2.com.

What do you dislike about Looker?

Sometimes reports take a little longer to load, and some advanced features can be confusing for new users. Improving speed and making the interface simple would make the experience even better. Looker could improve by making dashboard loading faster and adding simple tutorials or a guided setup option for new users. A more beginner-friendly interface would help teams learn and use the platform more easily. Review collected by and hosted on G2.com.

I find Looker easy to set up and navigate once reports are created. It’s really easy to change date ranges and filter reports for people viewing them, and the date-range updates are accurate. Setting it up is pretty simple with online instructions and tutorials. I also use it to create data visualizations. Review collected by and hosted on G2.com.
