Tableau taught a generation to see data. Kater lets your agent build it.
Tableau is still the most loved tool for drawing charts by hand. But dashboards live on its server, calculations hide inside workbooks, and each renewal costs more. In Kater, every model, query and dashboard is a file in git, and your agent builds them. One command moves a Tableau dashboard over in minutes.
In Kater
Every model, query and dashboard is a file in git. Kater compiles each change, tests check the numbers, and you review the diff.
04
Building by hand is slow next to an agent.
An analyst can spend an afternoon on layout that an agent writes in a minute.
“I can ask Cursor to spin up a chart in Streamlit and it looks equally nice, costing me a minute vs 2 hours of frustrating Tableau Container resizing.”
In Kater
Your agent builds the dashboard in Kater in that minute, on governed metrics, with permissions and History. It is not a one-off page.

Building with agents
Source of truth
Yes.Files in git: models, queries, charts, dashboards and apps. Every save is a commit.
In part.Workbooks live on Tableau Server or Cloud. A .twb file is XML, but there is no native git.
Coding agents
Yes.Claude Code, Codex and Cursor edit the files through the Kater MCP, or in a local copy.
In part.Tableau MCP reads data and content. Authoring through MCP was announced in 2026.
Checks on changes
Yes.A write through the MCP compiles first and is refused on error. Every change has a diff, History and Undo.
In part.Revision history. Moving content between sites needs the paid Content Migration Tool.
Answers in your own AI
Yes.People ask in Slack, Claude or ChatGPT. The agent sees only what that person can see.
Yes.Hosted Tableau MCP connects Claude and ChatGPT. Tableau Agent needs Cloud+ or the Tableau+ Bundle.
Metrics and trust
Shared metrics
Yes.Kater SQL: your warehouse’s SQL with DIMENSION, MEASURE and EVAL. Defined once, read everywhere.
In part.Published data sources share fields. Many calculations still live in each workbook.
Dashboards and apps

Where Tableau is ahead
Tableau does some things better today. Here is each one, and why teams still
select Kater.

More warehouses
Tableau connects to dozens of databases, files and apps, live or as extracts. Kater connects to Snowflake and DuckDB today.
Why teams still select Kater
Kater goes deep on each warehouse it supports. Queries run live, and the compiler checks each SQL dialect before a query runs. Have a warehouse we do not support? Request it.
Tableau comes with Salesforce’s scale, a long track record and a large partner network. A vendor that size also sets one roadmap for thousands of customers.
Why teams still select Kater
Kater is ready for enterprise: SOC 2 Type II, row-level security, access filters, grants and SSO. And you work with the people who build it. You decide how you pay, and you help decide what agentic BI becomes.
Tableau Cloud is priced per user per month, billed annually. Standard is $75 for a Creator, $42 for an Explorer and $15 for a Viewer. Enterprise is $115, $70 and $35. Tableau Agent needs Cloud+ or the Tableau+ Bundle, priced by quote, and Tableau Next starts at $40 a user a month.
Kater
A 30-day free trial with every feature, then a subscription quoted for your team. Kater does not charge per viewer or per dashboard. Kater runs no chat of its own, so answers run in the agent your team already uses.
Moving from Tableau
One command reads a Tableau workbook and rebuilds a dashboard on your Kater model. It maps each sheet, calculation and filter, checks the numbers against Tableau, and asks you only about what it cannot match.

Compared every chart with Tableau. All match.
Preview ready. Review it, then publish.
One command moves one dashboard. Kater rebuilds it as a private draft in minutes, checks its numbers against Tableau, and waits for you to publish.
Yes. Kater gives you governed metrics, dashboards, apps and AI answers. Every layer is a file in git that your agent builds.
How do we move a Tableau dashboard?
Run kater migrate on a .twb or .twbx file, or ask your agent to migrate it. Kater rebuilds the dashboard as a private draft in minutes, compares its numbers with Tableau, and waits for you to publish.
Do we need to move our extracts?
No. Kater queries your warehouse live, so there is no extract to move or refresh.
Can analysts still build charts by hand?
Yes. They select fields, a chart and a place on the dashboard in the browser. Or they describe the chart, and their agent builds it.
Does Kater connect to our data sources?
Kater connects to Snowflake and DuckDB today. Have a warehouse we do not support? Request it on our integrations page.
Can we keep Tableau and add Kater?
Yes, for as long as you want. Both read the same warehouse. Keep Tableau for its dashboards, and add Kater to give your team’s agent one definition for each metric, your context and your access rules. When you want, rebuild one dashboard in Kater, compare the numbers with Tableau, then move the next one.
