Looker reviews

Looker is incredibly easy to use for a casual user, which most of our users are. As soon as your email is activated, you have access to the product and new users need very little direction to start getting value out of it.

Relative to other BI tools, the advanced charting functionality is somewhat limited, but frankly that's not the main reason we bought Looker. Data scientists can use another tool of their choice, we have Looker for people who aren't data scientists.

Easy to create dashboards without engineers needing to write code.

Still not very good yet for a multi-tenant embedded environment. Needs a lot of work to set up and the API is slow.

It's really user friendly and easy to present or store data from other sources.
It has a lot of chart types and ways for presenting data.

Sometimes it lags when using big data sets, so it takes some time to render the complete report.
When building a report dimensions search also get some lag.

It's a great data exploration tool for users who normally would get anxious when given a large dataset in something like Excel. It's generally simple to use and there can be unlimited Viewers (users at the lowest permissions level) through the enterprise product. Data Visualization is essentially done for you and Exploers (users at the second level of permissions) can build new visualizations & turn them into interactive dashboards.

On the Looker platform, Explorers can locate a view (called an Explore) and then are given a list of dimensions and measures they can pull into a table. Users can create new dimensions using calculated fields and then save their views so any users with Viewer permissions (and up) can see what was put together.

With simplicity comes lack of flexibility. More skilled data analysts will want more flexibility than Looker can provide but at the same time you need to have highly skilled Data Analysts to be the Developers (high level of permissions) to set up the data so that less skilled analysts (the users who benefit from Looker most) who are Explorers don't build views that grossly misrepresent the data.

My biggest pet peeve with this software as an Explorer is that you cannot make calculations on the base data...only the data that you pull into your table (called table calculations). That is a major feature that Tableau has that Looker does not have at the Explorer permission level. Of course developers can use LookML (Lookers data language) to create a new column...but a Developer license is more expensive and creating the fields take time and it's something you constantly will need.

very quick deployment, self serve abilities for the business users are very high.
Mediation layer management is very good, it is "Code" based and not setup based so it is very easy to replicate/versioning and find "Hacks" to many needs, and versioning is managed by GIT.
Support is amazing, always available.

Still lacking a little bit on the graphic side, Would really love to have some more buildin dynamic graphs.

I love the customization of Looker, and that you can put large amounts of data into the hands of anyone -- in a way that makes sense [to them]!
While their product is great, it speaks volumes to the team. It's an amazing group of people that continue to receive feedback from their customers and iterate time and time again on their product. They truly care about data and their customers, and they want to empower them the best they can.

When modeling views, I wish you could define better filters for measures but it's limited. There are workarounds, meaning modeling out several additional dimensions to arrive at the measure you need to pull regularly, but it'd be much more efficient to allow for measures to be more nuanced.

Large dashboards (with 25+ tiles) can take awhile to load, which is understandable. Once their "merge results" feature is fully rolled out and we're able to save them as new tiles or looks, it should help resolve the need for so many tiles.

Neither of these two things are a big deal, and I wouldn't let this deter you from considering this software.

Provisioning security allows us to control the user experience (and only show users things they would actually care about). This makes a dashboard or data product rollout far smoother. Additionally, the customer support (especially through the chat interface) is absolutely fantastic. Because Looker creates a custom URL for each explore you're working on, you can share with Customer Support your exact problem and work together to find a solution.

Looker Sales told us beforehand that it "writes the most performant SQL possible." I have not found this to be the case, as it often casts and does a few other things (I suspect to make it runnable no matter how you've set up your data). There are some limitations on the visualizations, etc., but Looker Customer Service has been super responsive when those come up.

DS team creates dashboards mainly for non DS specialists in our company, they can easily track product lifetime, download the data into excel if needed. It improved my quality of daily work.

It gets down very often, requires very good internet connection and building dashboards is not very easy and intuitive for non professionals, requires time to get used to it.

I like that you truly do not have to understand SQL to end up being an expert and ask the ideal concerns in Looker. Looker is continuously making updates, they deliver really rapidly. I have a favorable outlook of this item.

I dislike for how long it takes given that it never ever truly caches the information. I need to truly make certain the questions I compose or the concerns I ask are really restricted as an outcome.

Looker is a very complete tool that allows you to build customized dashboard and KPI tracking reports. I really enjoy the level of customization it allows (different type of charts, tables, etc.) as well as how easy it is to share it with your team. I recommend this tool!

Looker requires a bit of technical knowledge about data analytics in order to customize some of the tables and reports. If you don't have much knowledge in this field, it might be a bit hard to create the reports and tables with the data you're looking for.

When I first saw Looker (during a long BI evaluation process where we demo'd perhaps 5-10 tools) I knew it was what I had been hoping for in a BI vendor. The ease of dragging dimensions and metrics onto a canvas, the fluid way that you could generate reports, and the simplicity of drilling down into the source data all suggested this was a tool that had been built well from the ground up.

Other vendors seemed to trap you into a narrow view of your metrics, but with Looker the only restrictions were the ones built into your data model. It could easily flex to accommodate whatever data you wanted to look at.

The LookML language and the way Looker is designed to interact with your data is pretty brilliant. Even a non-data scientist and non-SQL user like me could get the hang of the basics ;)

The range of options, the configurability, the flexibility...all aces. Really you only get stuck by your imagination, the tool is powerful enough that you can solve most problems if you have the know-how.

The team is also great. Awesome culture, friendly support.

They have a continual flow of new features and improvements.

You do need a good BI person or ETL developer to really get the most out of this tool.

Setting up your data model really well and going to the outer limits to solve some particularly difficult queries are all things I would have had a hard time doing without technical resources on the team.

Of course it's possible Looker helps with a lot of this during implementation; we pretty much controlled our own because we had the folks in house to do it.

It's a great product for giving people in all departments of your company access to data and allow them to explore what your data can provide. Rather than having to always go to the Business Intelligence or Analytics team, people of any level can query data without any SQL knowledge or understanding and yield results that are either directly actionable or ask more questions that can be answered using Looker. We ran an initial 30 days trial with a view that only our analysts and BI team members would use it. By the end of the 30 days, everyone from the COO down to the account teams were using it. It's amazing.

Furthermore, the vendor is smart, responsive and constantly improving the product, delivering a new version approximately every month. Their customer service is second-to-none and they are always happy to hear about new features that you need in the product. Very pleased overall with their service, strategy and plan to expand our use of them to our clients over the next few months.

Looker are still very heavily US based. They have just started an EU office, but support is still largely limited to US West Coast hours (although they seem to wake up at stupid o'clock to deal with some of our issues and plan to have support in the EU soon).

Things I like about this product:
1. Ease of use by our users - very intutive
2. Integration with our big data platform and databases. We use ours with Redshift and Aurora and they take most advantage of both systems.
3. Their super awesome customer support - always available chat who are really good at what they are doing.
4. Custom install options along with their hosted solutions.
5. Their whole team is involved with the product and customers top down. Really appreciate their responsiveness and customer-centric approach.

We really don't care about visualizations, but that can use some improvement to those who care.
The LDAP integration setup is a pain. It works well once it's all setup.
There is no roll-back once a version is installed. Work around is to restore from a backup. Would love to be able to do that as sometimes things don't always work the way we are used to and might require a rollback.

Looker is incredibly easy to use, and it easily scales with your technical abilities. As an Analyst, I can create very easy to use self serve reports for stakeholders. This saves time and effort for both parties. Looker also has a very intuitive way of organizing data and letting you quickly visualize data in your warehouse. It is reliable and the data visualization options are abundant. Our leadership team is miles ahead of others I've seen because of how quickly they were able to learn how to use Looker.

I don't necessarily see this as a con, however I think there is a big opportunity to help guide some new users through some of the more technical setup of Looker. I relied on a mentor to help take me through LookML and Models/Explores, but I would have loved to have some in product help with this.

* LookML because it enables a scalable semantic layer wherein business rules can be defined in a single place and logic is code based thereby enabling version control, testing and auditing.
* Extendability because the data platform focus enables businesses to serve data to applications and people through a single component
* Customer experience focus

* It can be hard to navigate the huge volumes of content that users build on Looker and find the canonical/VIP products that are the foundation for any company

Looker has been a game changer for us. It connects easily to our database and allows internal users to dig into our data and optimize media campaigns without having to write SQL code. The dashboards are easy to create and customize, and the fact that it can be embedded into a website allows us to share with clients without having to mess around with permissions.

Not exactly a con, but we tend to join most of our tables and clean our data in snowflake rather than Looker, so I can't speak to the advanced develop/derived table features.

Everything.
Looker made it sexy for BI developers, and intuitive easy to use for business user.

Their support is extremely knowledgeable and always available if you need any help.
Their engineers are brilliant and their hard work is allowing frequent releases that are going in the right directions.
Looker is customer driven and will deliver what makes sense for every user.

We love the creativity and flexibility this tool is offering us, as we are able to manipulate LookML to create anything, from data extract to Process automation.

Their growth is EXPONENTIAL.
Their Doc is well maintained so you are never lost.
Their community became part of their offering, you cannot find this elsewhere.

We have been satisfied since day 1!

I dislike the fact that our internal users are not curious enough (or don't get it) to explore data on their own. Maybe a different UI would help people discover on their own.

Looker allows you to work with virtually any data warehouse, and setup is not difficult. LookML is easy to work with, and allows non-developers to create content for their teams. Embedding Looker in our web app was relatively painless, and is a big improvement over our prior reporting system. Sharing content is super easy with scheduled reporting, and the variety of formats gives us solutions for different types of users.

I would like to see more visualization options, and enhanced capabilities with scheduling.

Looker's customizable dashboards are the heart and soul of the platform, and the most valuable part in my opinion. I can (and do) create dashboards for almost everything, from customer engagement, to content performance, and even technical metrics of a web application. This freedom to track and visualize almost any data source within a business is just incredible, and well worth the steep learning curve.

Looker can aid in team productivity as well. We use quarterly dashboards to track key metrics, so that everyone can see (in real-time!) how our organization is doing. It's very encouraging for the team to actually see progress over time in a chart, rather than just hearing/reading numbers.

Looker can feel clunky. This is not just because you need to know SQL to really use it well, but because the UI is slow, on occasion. Granted, if your data warehouse is slow/enormous, Looker can only do so much. But even for regular data analytics tasks, it can be sluggish.

Also, I do not like some of the predefined formatting for graphs/charts/visuals. The size-to-information ratio seems way off at times, but perhaps this is customizable and I have not discovered the settings yet.

So many things are done right:
- The simplicity of creating a meta schema using lookml, the learning curve is lightning fast
- The flexibility of the system, making data available to intern customer has never been so easy
- The support team is really knowledgeable and fast to answer
- The roadmap is clear and moving forward as a great speed. Most missing features that we have in mind are usually in development when we ask
- A really fun team, every meeting with looker is always a pleasure

Even if the team is moving fast and offering more and more features, they still lack on some of them. Mainly on dashboards.
It went a long way since the early days and now I'd say that 95% of our needs are covered.

On the other hand, their releases are so fast it's hard to keep track with all that was already implemented, the documentation is always a bit behind and searching for something precise on the discourse page can be a nightmare.

Looker is extremely intuitive and accessible for end users. This has made training and driving adoption across the company a breeze. It has really opened up our data to a huge number of non-technical users. Their customer support is also excellent.

As part of our evaluation we trialed several other providers that I think would have provided about 80% of the value at a dramatically lower cost. For our organization it made sense to go with the best in class, but for a more cost-constrained organization there might be better options out there.

The ability to compare data from different sources in one place is great - this allows us to better understand our user base, their performance on our platform - everything from health to revenues and the nuances we use to grade and measure our users.

Looker provides lots of flexibility in its set-up, but that could create confusion in the user experience. You need to really know what you're doing, understand data and its presentation to set Looker up to be most optimal. If would be great if Looker could visualize better, and also allow for over time analysis.

YAML like LookML
Ability to have comprehensive data models
Ease of training users to self-serve user defined Dashboards and Looks
Great usage statistics via the System and User Activity explores

The visualizations need to catch up quite a bit so they look more professional grade a-la nytimes style story telling viz. Can accomplish more sophisticated things using API for sankey or other visualizations but these need additional work. Ability to run cross DB queries in case of multiple warehouses / data marts.

It's really easy to create dashboards and reports. Even though we need to code some things it allows to be really flexible in the way you create and display data.

I had to learn more technical information, the code, and how to work with development and live versions of the models.

For your developers, the customer service is superior. They also do a great job reaching out to your primary users. With respect to frontend users, those using it for simpler data retrieval/review, their interface is rather easy to use and logical to work through. They do a lot to make the system as simple as possible. Only your BI developers and/or data engineering team can clutter the space.

If you decide to purchase the non-customized version, the color palette Looker uses is rather bland (More noticeable to executives and heavy users-most users will be fine with it though). The company's integrations are rather limited, but supposed to improve with Looker 5 (via the Action Hub). However, it seems that most integrations will require purchasing from third parties, instead of being a Looker hosted and "controlled" solution you purchase through them. That complicates the process.
