So, you’re considering embedding Metabase in your application to deliver analytics to your customers. How would that work?
In this article, we’ll:
- Start with the target experience for your customers that you’ll deliver.
- Give a brief tour of the challenges to providing self-service reporting to multiple tenants.
- Talk through the relevant features Metabase offers, and how they work together to solve those problems.
The target user experience
To level-set, let’s start with what the finished analytics experience will look like from the perspective of your customers.
- Your company: Megafauna Analytics
- Customer 1: MammothCo
- Customer 2: RhinoCo
Say you’re a B2B company, Megafauna Analytics, and you’re using Metabase to provide reporting to your customers by embedding Metabase in your app at megafauna-analytics.com.
Here’s an overview of the customer experience: Woolly from MammothCo logs into your app at megafauna-analytics.com, then navigates to the analytics page you’ve set up for MammothCo. There, Woolly is treated to a set of screens featuring polished dashboards and charts showing MammothCo orders, transactions, and other sandboxed data you’ve provided, all of which feature your - Megafauna’s - brand colors.
More than just viewing static dashboards, Woolly can click on data plotted on the charts and drill-through. For example, he could zoom in on a particular week of transactions, or click on a bar in a chart to pull up a table listing the unaggregated rows that populate that bar.
Plus, with the Metabase’s graphical query builders, Woolly can slice and dice MammothCo data to his heart’s content. He can use the editor’s powerful querying primitives, as well as custom expressions for more sophisticated queries, to find answers to questions your dashboards don’t address — all without seeing any data from RhinoCo or other customers.
So that’s the story. How do we get there?
The challenges to creating multi-tenant, self-service analytics
By multitenancy, we mean a shared application instance where groups of people (groups like MammothCo or RhinoCo) enjoy access to different permissions, and therefore to different data. And by self-service, we mean that the application should give people the ability to create their own reporting, in addition to whatever reporting administrators provide.
Before we get into how Metabase delivers multi-tenant, self-service analytics, let’s first identify the problems we’ll need to solve. To give Woolly the experience outlined above, we’ll need to:
- Embed Metabase in your application (megafauna-analytics.com) in a way that gives people access to a query builder and drill-through functionality.
- Make the dashboards and charts match your (Megafauna’s) brand colors.
- Tie a given user in megafauna-analytics.com to a user in your embedded Metabase instance.
- Limit the data the users can see to just the rows and columns they’re allowed to view.
Now let’s go through the four features Metabase offers that combine to solve these problems.
The four features necessary to set up multi-tenant, self-service reporting
We’ll go through each feature, but here they are at a glance:
- Full app embedding. Add drill-through to embedded charts and dashboards, curate collections, expose a query builder pre-filled with a dataset, or even expose the entire Metabase interface.
- White labeling (branding). Make the Metabase charts and dashboards in your app match its look and feel.
- Single sign-on (SSO). Enable your app and Metabase to agree on who their users are and what data they can see.
- Data sandboxing. Let your users explore their data, without seeing anyone else’s data.
Full Metabase app embedding
Though our focus will be on full app embedding, there are several ways to handle embedding Metabase in your app. And because “embedding” is such an overloaded term, it’s worth going through the different ways you can use Metabase to embed charts and dashboards in your app.
Let’s start with the open source options:
Metabase embedding options
Public link embedding
The dead simple option (and it may not even technically qualify as embedding). You put up a question or dashboard in a Metabase instance, send someone a link to it, and tell them not to share it.
One step up, as the link is still public, but the chart is visible in your app via an embedded iframe.
Same as the public embed, but now it’s an iframe secured by a signed JSON Web Token (JWT). To set up secure embedding, you’ll need an iframe with a link to the question or dashboard on the front end, as well as server code on the back end to create the token. You can then sign tokens with a user ID, and do some cool things via parameterization.
For example, you can create filters on dashboards that can accept parameters, and filter that data in the dashboard based on those parameters. You could have a parameterized dashboard that accepts a user ID, so when that user logs in, the dashboard would only show users data restricted to their user ID. In other words, you can create a generic dashboard for user data that any user can access, but each individual will only see data relevant to them.
The big drawback with secure embedding is that customers will not be able to drill through the data. And the reason drill-through is unavailable is because Metabase does not know what data permissions the user has access to. Metabase may know that the user is
user_id: 13, but there’s no connection between that user 13 and a user account in Metabase (and therefore the groups and permissions the user has access to). To link accounts across your application and your Metabase instance, we’ll need full app embedding and single sign-on.
With Metabase Enterprise Edition (and coming soon in the open source edition), you can customize what happens when people click on your charts in the dashboard, but this feature is manual, and limited to parameterization.
Full app embedding (Enterprise Edition)
Full app embedding, in combination with SSO and data sandboxing, is what makes the self-service reporting possible. Like the simpler embedding options above, you’re still using an iframe to embed Metabase, only this time you can embed any Metabase screen you want, complete with full interactivity. Combined with SSO and data sandboxing, your embedded Metabase instance will know who Woolly is and what data he can view, which means Metabase can let Woolly drill-through his data without being able to see any data from RhinoCo users or other tenants.
And because you have the full Metabase app at your disposal, you can provide MammothCo users with collections, dashboards, and predefined questions, such as week over week transactions. You can also expose Metabase’s notebook editor, which would allow customers like Woolly to create their own questions and dashboards (and annotate them with Markdown) based on their evolving needs for data.
White labeling (branding)
Metabase’s white labeling feature allows you to change the colors and branding of Metabase to match your company’s application. It’s one of those small, simple changes that can make for a much better user experience.

The goal with single sign-on (SSO) is to associate users in your app with users in Metabase. By using SSO, you avoid the awkward login screens where your charts should be. Without SSO, a user would log into your app, but would still have to log into your Metabase instance to view individual embedded dashboards and charts – a less-than-ideal user experience.
How SSO works with Metabase
Let’s say you set up a MammothCo user in your app, megafauna-analytics.com, with
name: Woolly; user_id: 13. To coordinate with your Metabase instance, you would then (manually or programmatically) set up a user account for Woolly in your Metabase app. Next, you need to associate Woolly’s ID in your app, megafauna-analytics.com, with Woolly’s account in your Metabase instance. To do that, you simply add an attribute to Woolly’s account in Metabase to indicate that Woolly’s
user_id in your app is
With SSO set up, when Woolly logs into megafauna-analytics.com, a signed token is generated that attests to his identity and the attributes you’ve set for him in your Metabase instance. When Woolly navigates to pages with embedded Metabase charts or dashboards, Metabase can tell from the
user_id attribute attached to the token that Woolly is user 13 and should only be able to see data you’ve made available to that user ID.
That’s the basic idea, and there are several ways to set it up:
For internal analytics, companies usually use SAML, LDAP, or Google Sign-in. For external analytics, companies usually prefer (and we recommend) JWT SSO.
How you want to handle authentication is up to you, but you must set up SSO in order to coordinate permissions across your application and your Metabase instance.
To learn more, see documentation on:
Now that your SSO is providing Metabase with details about your users, those attributes can be used to filter what each user sees, down to the columns and rows of specific tables. This is data sandboxing, and it’s a powerful tool, so we’ll only be able to give an overview of how it works.
For example, if your
orders table contains all customer orders, you could filter that table based on a column, say
user_id. You can assign an attribute,
user_id, to your users in Metabase (and attach that attribute to their login tokens), so that when users log in and view
orders, they’ll only see data with rows that match their
If you need even more control, you can create custom views of tables with saved questions. For example, let’s say you don’t want ANY users seeing a specific column in the
orders table. In this case, you could create a custom view of that table with the relevant column omitted by asking and saving a question in Metabase.

We hope this article gave you a high-level understanding of how you could deliver self-service reporting with a multi-tenant Metabase instance embedded in your web app. Here’s a quick summary with links to our documentation if you’d like to learn more about a particular topic.
- Put iframes in your application, and embed the full Metabase application.
- Use white labeling to brand your Metabase instance.
- Set up SSO (SAML, JWT) to link users in your app with your embedded Metabase instance, and attach user attributes to signed tokens.
- Use the attributes to sandbox the data to ensure users can only see the data they have permissions to view.
Full app embedding, as outlined above, is a great option for most companies, but it’s not the only option for providing self-service reporting. See how to use Metabase to deliver analytics to your customers for an overview of the different ways you can use Metabase – from a simple setup (no embedding necessary) to setups that offer staggering customizability – to find the approach that’s right for your organization.
