🗄️ Hex is now in Codex​

At Hex, we want you to be able to analyze data from wherever you do your job. And we’re working hard on building our leading analytics agents and our unique approach to context into the places our customers are working.

Starting today, you can bring Hex directly into Codex to run analyses, pull in existing work, and spin up new projects.

💪 What you can do​

• Kick off Hex analysis from Codex - Need to understand churn by segment? Dig into pipeline performance? Codex can invoke Hex to pull the data, run analysis, and return results without switching tabs.
• Pull Hex Threads into Codex - If you've already done analytical work in Hex, you can pull in your prior Hex work to incorporate data into whatever you build.
• Control Hex programmatically using the CLI - For more specific, structured tasks - such as creating projects, adding cells, or configuring analysis - you can leverage the CLI connection in Codex for a more precise interface into Hex.

To use Hex in Codex, head to Plugins and install the Data Analytics plugin. Then connect to Hex and you're ready to go!

🔌 Hex is now an MCP client​

Your data tells you what happened. The why lives somewhere else — in strategy docs, meeting notes, Slack threads, customer conversations.

Today, the Hex agent can read all of it.

Connect any tool that exposes an MCP server to the Hex agent.

As part of our public beta, we’re launching with two named connectors: Notion & Linear. Other MCP servers can also connect to the Hex Agent, and we have more named connectors in the works.

That means when your team asks a question in a Thread, the agent isn't just looking at your data — it's cross-referencing the Notion doc from the product launch, the Linear ticket that closed last week, the strategy doc your team updated before the weekly sync.

👷 How it works​

1. Go to Context Studio → Apps → Add MCP server
2. Add Notion, Linear, or any tool that exposes an MCP server
3. Once enabled, users connect their personal accounts via the + menu in any thread

Connecting more apps is only half of it — the agent works through semantic models and definitions your team has already validated, so the answers are consistent and can be trusted.

Available today in public beta for Team and Enterprise plans.

🛌 Signed embedding for Generative apps​

You can now use the Hex Embed API to securely embed Generative Hex apps in your web application with pass-through authentication and row-level security.

This brings a whole new level of customization to embedded Hex apps. You can match the visual style of your brand or web app with the help of the Hex agent!

A great way to jump-start this work is to copy and paste your own css or a screenshot of your web app into the prompt bar and the agent will do the rest.

A side-benefit of this is that app interactions are way snappier than classic Hex apps — filters, drill-downs, and re-renders feel near-instant, which makes a real difference for embedded experiences.

Learn more in our docs about signed embedding with Hex.

🗂️ Connect repos as agent context​

Your data doesn't exist in a vacuum. Your dbt models, transformation logic, and app instrumentation hold a lot of context that makes your warehouse data actually legible. Now the agent can use it.

Connect one or many repos to your Hex workspace and the agent will reference them when answering questions — understanding how a table was built, what upstream logic shaped it, or how a product event was implemented. Admins can connect repos via API; once uploaded, they appear in the admin panel with a last-updated timestamp, and the agent surfaces its retrieval steps directly in Threads.

🥟 Introducing: Generative Data Apps​

Today, we're introducing Generative data apps in beta. Anyone can build a powerful app simply by prompting the Hex agent. Everything stays grounded in your trusted data, helping you avoid inconsistencies or hallucinations while building powerful, flexible dashboards and apps.

Vibe-coding environments are fun and powerful, but lack governance. Dashboard builders have access to your trusted data, but limit your creativity. And hand-coding apps yourself is…hard. Generative data apps break the tradeoff.

🧑‍🎨 Every data app is a prompt away​

Generative data apps harness the infinite flexibility of code-gen, allowing you to build, well, anything - dashboards, data editorial stories, or even interactive presentations. The possibilities are endless.

Our visualization team obsessed over the out-of-the-box charting components so they look great by default, but if you want to go further, the whole thing is yours to extend because behind the scenes it’s all just javascript. Just prompt the agent.

When the Hex agent builds a data app, it leverages the trusted context your team has already curated in Context Studio: endorsements, guides, semantic models, git repos, and existing trusted dashboards. The result is a more accurate output, with insights grounded in the facts of your business.

Data teams maintain observability since the apps leverage a Hex project for queries and transformations. Publishing and getting fresh data works the same as any other dashboard - no need to worry about figuring out deployment or using an app hosting site.

🎨 Examples of things you can build​

Prompt the agent to “build an editorial style app.”

Or you can “Create a slide deck-style presentation about squirrels in Central Park…with an Oatmeal theme”.
