Looker loses slightly more companies than it gains here, and the two flows look different. Thirteen describe moving onto it — six from Tableau and three from Power BI — with individual buyers citing cost, Google Cloud fit, live-data requirements, self-service or speed. Eighteen describe moving off it: eight to Sigma, Omni or Metabase, four to Tableau or Power BI, two elsewhere, and four without a settled replacement. The complaints that recur among its lower raters are that only the data team can really use it, that it is slow and glitchy, that its visuals are limited, and that some buyers believe product investment has slowed since Google’s acquisition. Self-service runs through both directions: it is a recurring complaint, and also what several positive buyers praise once Looker is configured for business users. This page covers Looker, the BI platform, not Google’s free Looker Studio. For the neighbouring decisions, see Tableau alternatives and Power BI alternatives.
The alternatives, by destination category
Every destination buyers name, grouped by the kind of tool they moved to. Eight went to Sigma, Omni or Metabase, four to Tableau or Power BI, two elsewhere, and four have no settled replacement.
What lower-rating Looker buyers complain about
That only the data team can really use it. “I don't think it's very self-serve,” says a buyer rating it 5. Another, at 4: “The difficulty of self-serving is probably the biggest con.” One at 6 says “it's great for a data analyst, but for people outside of those scopes, it's not as good of a tool.” Another, also at 6: “The problem I would say is the barrier to entry.”
That it is slow and glitchy. “I feel like it takes forever to load. It's really glitchy,” says a buyer rating it 4. One at 6: “Looker is glitchy.” Another, at 5, describes reports timing out and quota errors: “So many of our reports are unused today.”
That its visuals are limited. “It does not bring good quality visualization,” says a buyer rating it 6. One at 5: “It suffers from a poor visualization experience.” Another, also at 5, compares it with the tool they used before: “Tableau was much better to use.”
That it has stalled since Google bought it, in some buyers’ view. “I think Looker since Google has bought them has just plummeted. Their support sucks,” says a buyer rating it 4. Another, at 5: “it was a good platform until Google bought them, and they haven't really invested in the platform.” Several also point to AI — one at 6 says “Looker is missing that AI-native tooling.”
And price, for smaller companies. A buyer rating it 6: “It's just very pricey for smaller organizations.”
Where buyers go
Eighteen companies here have moved off Looker or are partway through a move. Several more are weighing one — to Hex, Omni or another self-serve platform with AI built in — but have not made one.
Sigma, Omni and Metabase
One company is consolidating its reporting into Sigma “to have less BI tools spread across the org,” finding that “it has much better data visualization capabilities than Looker.” An education company ran a proof of concept against Power BI and Tableau, and “Sigma came out to be the winner.” A smaller company “got rid of both of those two things in favor of a tool called Sigma” — Looker and Amplitude — and adds that Sigma is “a lot cheaper.”

One company moved “due to ease of connection with other AI platforms so that our team can get more efficient data with LLMs.” Another left because “it's hard for folks to self-service” in Looker, and finds “Omni seems really easy to use, especially with their AI assistant.” A third moved after its analysts found Looker’s per-query costs and table joins harder as its data grew.
No head-to-head published yet
A company consolidating its dashboard tools: “We have used Looker in the past. We have migrated over to Metabase recently.”

Tableau and Power BI
“We've moved away from Looker,” says one buyer, who finds that in “other tools like Looker and Mixpanel, the data visualization is not the strongest.” At another company, the buyer is “not sure why the decision was made to move from Looker to Tableau.”
A media company rating Looker 5 is shifting its marketing dashboards: “Power BI is just better and more user-friendly.”
A very large healthcare company has put Looker in a “sunset designation”: “Looker is moving either to Tableau, ThoughtSpot, or MicroStrategy, depending upon the use case.”

Elsewhere
A small consumer brand is moving down to Google’s free tool: “We are switching from Looker to Looker Studio, or Google's, right now.”
No head-to-head published yet
A consumer brand replaced its Looker reporting with a cohort-analysis tool: “we used to use Looker and Daasity, but just moved away from that.”
No head-to-head published yet
Four more left without a settled replacement. One found Looker “just got too cumbersome” and now reports by hand; one organization blocked Google tools, so “We're no longer technically able to build Looker dashboards”; one “did try to use Looker, but we abandoned it”; and one is choosing between Count and Sigma: “we're not going with Looker because it's too expensive.”
Read across the groups, the moves to Sigma, Omni and Metabase cite different combinations of self-service, visualization, cost and connection to AI tools. Among the moves to Tableau and Power BI, one buyer cites visualization and another user-friendliness; the reasons for the other moves are not established here.

Thirteen companies here describe moving onto Looker: six from Tableau, three from Power BI, three from Google Analytics or Data Studio, and one from Mixpanel.
From Tableau, for cost and Google fit. One company “just changed over from Tableau because it was too expensive to Looker” — its buyer adds, “I like Tableau a lot more, but it is far more expensive.” A retailer moved because Looker is “much easier for the integrations and to read the data as well.” A large company moving onto Google Cloud says the Google products “make natural connectivities to themselves.”
For live data. A very large company: “Tableau is pretty, but cannot handle a large volume of live data, so we moved to Looker.”
From Power BI. Three companies moved from Power BI: one cites self-service, another describes Power BI as slow and clunky, and a third is moving away from Microsoft products. They are covered in Power BI alternatives.
From Google’s own tools. A food retailer: “when Google transitioned to GA4 instead of GA 360, it was a bit harder to build different dashboards, specifically executive dashboards. Therefore, we transitioned into Looker.” Another company is moving off Data Studio onto Looker.
Not every arrival is happy. A buyer at a company that moved from Tableau rates Looker 5: “It's not very self-serve.” Another, also at 5, finds that “Looker does seem a little complicated for me to use.”
The companies leaving skew smaller: eight of the eighteen have revenue under $50 million, while six of the eleven arrivals with known revenue are above $1 billion. The interviews do not establish company size as the reason in either direction.
When does staying on Looker make sense?
Positive buyers emphasize its fit with Google Cloud and self-service once it has been configured for business users. Several still raise price and the learning curve.
Fit with Google Cloud. A buyer rating it 9: “As we have all the data in Google Cloud in our company, it is easy for us to have this tool.”
Self-service, where it is set up for it. Another, at 9: “It has really helped us be more self-serve and it is much faster in terms of loading and using the data versus even Tableau or previous toolkits.” A third, also at 9: “As long as we configure it in a way that's easy for them to use, it's very intuitive, it's very quick.”
Self-service is one of the clearest divides in what buyers say about Looker. Lower raters describe a barrier to entry outside the data team, while positive buyers say it can enable self-service once the environment has been configured for business users. It appears on both sides of the migration evidence too: one company moved from Power BI to Looker for self-service, while another moved from Looker to Omni because its users struggled to self-serve. That points to configuration and user type as part of how buyers experience it — an inference, not something these interviews establish.
Even positive buyers flag price and the learning curve. A buyer rating it 10: “I don't think Looker has weaknesses outside of price point.” One at 9 says “you need a little learning curve on how to create your own looks.”
One buyer describes it as entrenched. A buyer rating it 6 would not move even with switching costs aside: “right now the Looker is just too entrenched to consider dropping.”
Our read — ours, not a buyer’s — is that Looker’s inbound and outbound migrations have different shapes in these interviews. Six of thirteen arrivals came from Tableau and three from Power BI. In the other direction, eight of eighteen departures went to Sigma, Omni or Metabase, compared with four that moved to Tableau, Power BI or a mix of established BI platforms. Among departures where buyers explain the move, reasons include self-service, visualization, cost and AI connectivity. The two groups also differ in company size, though these interviews do not establish size as the reason.
Common questions
Why do companies leave Looker?
The eighteen companies leaving Looker here give varied reasons: self-service for people outside the data team, visualization, cost, connection to AI tools, and consolidation onto another BI tool. Lower-rating buyers also cite slowness, and some believe product investment has slowed since Google's acquisition.
What do companies replace Looker with?
Of eighteen companies here that moved off Looker or are partway through a move, four went to Sigma, three to Omni and one to Metabase; two went to Tableau, one to Power BI, and one is splitting its users across Tableau, ThoughtSpot and MicroStrategy; one went to Looker Studio and one to Lifetimely. Four have no settled replacement.
Is Sigma a good alternative to Looker?
Sigma is the most common destination in these interviews, taking four of the eighteen departures. Buyers moving to it cite visualization, ease of use, cost and consolidation onto one BI tool; one notes that during setup, data took far longer to populate in Sigma than it had in Looker. Across the corpus, Sigma rates 7.1 and Looker 7.2.
Is Looker too expensive?
Price comes up among its lower-rating buyers, especially at smaller companies, and several departures cite cost. Companies moving from Tableau to Looker, by contrast, describe Looker as the cheaper option. These interviews do not establish total cost of ownership.
Why do companies move to Looker?
Thirteen companies here describe moving onto Looker: six from Tableau, three from Power BI, three from Google Analytics or Data Studio and one from Mixpanel. They cite cost, fit with Google Cloud, handling live data and self-service; some arriving buyers still find it complicated.
