Credible vs. Hex

Hex is where analysts write SQL, Python and R in one document, with AI cells throughout. It is built to consume a semantic model rather than be one — so it sits alongside Credible more naturally than against it.

How Hex describes itself

What Hex is

Hex is a collaborative notebook and data-app platform — SQL, Python, R, no-code and AI cells in one document — with a Notebook Agent, Magic AI, a semantic model agent on its Team tier, and the ability to import modeled data from external semantic layers including dbt MetricFlow, Cube and Snowflake semantic views.

Category

Credible: AI-native analytics engine with an integrated data stack
Hex: Collaborative notebooks and data apps, with AI agents

Who it is built for

Credible: AI product and analytics teams, plus anyone who works with data — spreadsheet users through ML engineers
Hex: Data scientists and analysts working in SQL, Python and R

Primary interface

Credible: The agent you already use, over MCP — plus Workspaces, notebooks, reports and data apps for the people who want a UI. All of them consume the same model rather than being the place it lives
Hex: A notebook — SQL, Python, no-code and AI cells in one document

Modeling language

Credible: Malloy — a modeling and query language with imports, inheritance, and public and private members
Hex: SQL, Python and R, aimed at analysis rather than a shared governed model

What is open

Credible: Open core. Malloy is open source, and we build and maintain Malloy Publisher, the open-source server for Malloy models. Your model is code in your repository, and Credible is in the Apache Ossie ecosystem for semantic interchange
Hex: Vendor-owned, and designed to consume external models — dbt MetricFlow, Cube, Snowflake semantic views

How the model gets built

Credible: A coding agent with open-source MCP tools and agent skills, capturing context from where it already lives
Hex: Per-notebook analysis, with a semantic model agent on the Team tier; can import an external model

Governance

Credible: Governance as code. Access rules are annotations in the model itself — versioned, reviewed and composable like any other code
Hex: Workspace permissions and data connection scoping; governance is inherited, not defined here

Materialization and caching

Credible: One annotation on the source, in the same file as the logic it materializes — no derived-table block, no rollup definitions, no refresh triggers, no orchestration run to schedule. Optional per source: query your own warehouse directly, or hold a source hot in Credible’s in-memory serving layer, which is how a team on Postgres gets fast serving without buying a warehouse to get it
Hex: Caches cell and query results per notebook run; no shared materialization layer

How an agent finds the right data

Credible: Search. Typed targets — source, dimension, measure, view, even a dimensional value — are matched against an index of the model and come back ranked, so an agent asks for what it needs instead of picking a model and touring it
Hex: Per notebook. Hex imports a model from an external semantic layer, and its agents work within that notebook’s context

Where the model can be used

Credible: One model served to every surface — agents over MCP, plus APIs, an SDK, embedded dashboards, notebooks and HTML data apps. Results carry an interactive UI resource (MCP Apps, the official extension), so a client that supports it renders a real chart or table instead of the model re-narrating rows
Hex: Notebooks, published apps and embeds, for people rather than agents; imports a model rather than serving one

Scale and portability

Credible: Built for globally distributed, high-availability workloads. Warehouse-agnostic on open-source Malloy — BigQuery, Snowflake, Postgres, MySQL, Trino, Presto and DuckDB, which also reads Parquet straight out of object storage including Azure Data Lake — so the model travels
Hex: Scales with your warehouse for queries and Hex for compute

What you pay for

Credible: Usage, not seats — unlimited users on every plan, so adding people never changes the bill. Metered per organization on tokens, bytes processed, bytes served and hot storage, starting free. Your own agent’s tokens are never billed, and a query that runs on your own warehouse is not metered for the scan — only for the result it hands back
Hex: Per-editor seats plus compute, with AI metered as effort-based credits priced by task complexity

A different premise

Where Credible takes a different approach

These are differences in what each product set out to be, not faults in Hex. Credible was built the other way around from a BI tool: capture what your data means, enrich it into a governed model in open-source Malloy, and serve that meaning over MCP to the agent you already use — with a UI of our own available, but never assumed.

A shared model under the notebooks

Logic written in a notebook is scoped to that notebook, which is exactly what you want while a question is still being explored. Once an answer is settled, it helps for the definition to live somewhere the next analyst inherits. Malloy puts definitions in one versioned model with imports and inheritance, and Malloy notebooks read from that model rather than redefining it. Hex can consume the same model, so Credible works as the layer under Hex as readily as instead of it.

Governance declared, not inherited

Hex scopes access at the workspace and data-connection level and inherits the rest from the warehouse, which is reasonable for a tool analysts drive. Credible declares row, column and role rules as annotations in the model, so they travel with the definitions wherever those definitions are consumed.

The same definitions answer everywhere

Hex delivers notebooks, apps and embeds to people, and does that well. Credible ships notebooks, reports and HTML data apps too, and serves the same governed context over MCP to agents, applications, embedded dashboards and APIs — so one definition answers in an analysis someone opened, in a product feature and in an automated workflow that nobody watched.

The model is built for you, and it is open

Hex has a semantic model agent on its Team tier that helps build a model inside Hex. Credible’s coding agent builds the model from context that already exists across your stack, and the result is open-source Malloy — a file in your repository, served by an open-source server, rather than a workspace artifact.
