The facts, with their sources

What it does

Writes code: YesThe Notebook agent authors new SQL, Python, Markdown, pivot, input and chart cells from a natural-language request inside a Hex project.The Notebook agent has the ability to create new cells in a project. The agent is capable of creating Python cells, SQL cells, Markdown cells, Pivot…learn.hex.tech/docs/explore-data/notebo…
Debugs and fixes: YesThe agent diagnoses and repairs broken cells through 'Fix with agent' for multi-cell contextual debugging, or 'Quick fix' for single-cell syntax errors.The agent can fix your code with either Fix with agent or Quick fix.learn.hex.tech/docs/explore-data/notebo…
Whole-codebase work: PartlyScope is a Hex workspace, not a source repository: the CLI can script edits across many projects at once, but the agent itself works inside one project with others only as context.Use hex project, hex app, and hex cell to build analyses from your terminal — and make changes across many projects in one scripted pass.hex.tech/product/cli
Ships it: YesThe agent does not stop at a draft: it can lay out and publish the data app itself, and the API or CLI can then run published projects on a schedule.The Notebook agent can create and edit the layout of your published app, as well as publish the app for you.learn.hex.tech/docs/explore-data/notebo…
Done-for-you service: NoHex sells self-serve hosted software you operate yourself; Enterprise buyers get dedicated support and onboarding, not a team that builds your analyses for you.Hex is fully hosted, with securely-sharable connections, customized environments, and configurable compute.hex.tech/product/notebooks

How much it does unattended

Runs autonomously: PartlyScheduled Tasks run a whole Thread unattended, but in the notebook every agent edit waits on a human Confirm or Undo before it lands.All changes that the agent suggests must be accepted into the Notebook (Confirm) or rejected (Undo).learn.hex.tech/docs/explore-data/notebo…
Multi-agent: YesFor complex questions the main agent spawns purpose-built subagents that run in parallel on data discovery and charting workstreams.the Hex Agent uses subagents to break your question into focused workstreams that run in parallel — including finding the right data connections,…learn.hex.tech/docs/explore-data/notebo…
Agent permissions: PartlyDestructive steps need explicit approval and can be waived per thread, while admins separately gate web search, endorsed-only data and sensitive connections.Before the agent deletes cells in your project, you must select either Accept or Deny for the changes to take effect. Select Don't ask again in this…learn.hex.tech/docs/explore-data/notebo…

Which models it runs on

Claude: YesAnthropic models are first-class in the model picker (Opus 5, Opus 4.8, Sonnet 5, Fable 5) and are a supported BYOK provider on Enterprise.Opus 5 | $$$$ | Hard analytical judgmentlearn.hex.tech/tutorials/ai-best-practi…
GPT: YesOpenAI models appear in the same picker as GPT 5.6 Sol, Terra and Luna, and an OpenAI API key is an accepted BYOK credential.GPT 5.6 Sol | $$$ | Complex analysis at a lower credit costlearn.hex.tech/tutorials/ai-best-practi…
Open models: YesKimi 2.7 is offered in the picker as an open-source model Hex hosts itself, positioned as the low-credit option for well-defined asks.Kimi 2.7 is an open-source model we host on US-based infrastructure, known for lower costs.learn.hex.tech/tutorials/ai-best-practi…
Model choice: PartlyYou choose from Hex's own curated list per thread and admins can set a workspace default, but there is no routing and BYOK narrows the list to your provider's models.Hex does not do model routing — Auto defaults to a single model Hex chooses to optimize for speed, cost, and quality.learn.hex.tech/docs/explore-data/threads

Where you use it

In your editor: PartlyCursor, Claude Code and Codex reach Hex through the MCP server or bundled CLI, but that MCP surface is restricted to Team and Enterprise and is still in beta.Hex MCP server works with Claude Desktop, Claude Code, Cursor, ChatGPT, Codex, and Glean, as well as most standard MCP clients.learn.hex.tech/docs/api-integrations/mc…
On the command line: YesA first-party terminal tool creates projects, writes cells, runs analyses and starts agent Threads; using the CLI requires an Editor role or above.Create projects, write SQL, run analyses, and connect your agents… without leaving your terminal.hex.tech/product/cli
In your pipeline: YesThe CLI is a plain UNIX binary intended for CI and orchestration, and hex run executes projects programmatically to catch errors in a pipeline.Execute projects and apps programmatically with hex run. Integrate it into CI pipelines to catch errors and keep analyses in sync with changes to…hex.tech/product/cli
In a browser: YesHex is primarily a hosted browser workspace: notebooks, Threads and published data apps all run in the vendor's cloud with no install.Hex is fully hosted, with securely-sharable connections, customized environments, and configurable compute.hex.tech/product/notebooks

Whose machine it runs on

Self-hosted: NoEvery deployment option on the plan table is run by Hex — multi-tenant, EU multi-tenant, or a single-tenant add-on — so there is no customer-infrastructure install.Deployment Multi-tenant Multi-tenant EU Multi-tenant (contract only) or multi-tenant Single, EU Multi-tenant or multi-tenanthex.tech/pricing

What it costs to run

How it meters: YesBilling stacks a per-Editor monthly seat price on effort-based AI credits, with optional pay-as-you-go compute charged per minute at an hourly rate.AI features in Hex consume credits based on the effort required to complete the task. All paid plans include a credit grant, with the option to…hex.tech/pricing
Free tier: YesA standing free Community plan allows data connections and all cell types with 5 AI credits a month, alongside a separate 14-day Team trial.Community For hobbyists completing small projects and showcasing work. Freehex.tech/pricing
API access: PartlyA token-authenticated REST API lists and runs projects and manages users and connections, but the plan table restricts REST APIs to Team and Enterprise and keeps the Observability API on Enterprise.Admin APIs are available on both the Team and Enterprise plans; certain endpoints are exclusive to the Enterprise plan.learn.hex.tech/docs/api-integrations/ap…
MCP server: PartlyHex ships an MCP server so outside agents can search projects and run Threads, but it is gated to Team and Enterprise and the vendor marks it beta.Available on the Team and Enterprise plans. ... Hex MCP server is currently in beta.learn.hex.tech/docs/api-integrations/mc…
Bring your own key: PartlyEnterprise admins can route all inference through their own Anthropic, OpenAI, Bedrock or Google Cloud credentials; lower plans use Hex's provider accounts only.With BYOK, Admins can supply their own credentials so that inference runs through your organization's provider account instead.learn.hex.tech/docs/trust/ai-data-priva…

Buying it for a team

A company can buy it: YesTwo explicitly organisational plans exist beside the individual ones, with Team self-serve at a published per-Editor rate and Enterprise sold by sales.Team For companies collaborating with data and automating manual work. $75 per Editor / monthhex.tech/pricing
Seat model: YesPriced per Editor seat at $36 Professional and $75 Team, with a cheaper Explorer seat add-on on Enterprise; no seat minimum or ceiling is published.Users with the Admin, Manager, or Editor workspace roles are considered "Paid Author Seats". Users with the Explore workspace role are considered…learn.hex.tech/docs/collaborate/sharing…
Pooled budget: YesBoth models run at once: each paid seat gets a non-transferable monthly grant, and a shared workspace pool of add-on credits covers anyone who exhausts theirs.The shared workspace credit pool is your balance of add-on credits. By default, any user who depletes their monthly per-seat credit grant can draw…learn.hex.tech/docs/administration/cred…
Admin controls: YesAdmins cap credit spend per user, group or workspace, disable AI entirely, force endorsed-only data for Explorers, and block agent web search.Admins can control how many add-on credits each user is allowed by applying a credit limit to a User, Group, or Workspace.learn.hex.tech/docs/administration/cred…
Audit log: PartlyActivity logging covering projects, cells and users exists but only on Enterprise, viewable for 30 days in WorkOS or streamed to a SIEM.Audit logs are a record of the activities that occurred in the Hex platform, intended for use by security and compliance teams. ... Available on the…learn.hex.tech/docs/administration/work…
Single sign-on: PartlyOIDC single sign-on with optional enforcement is Enterprise-only, and the vendor states plainly that SAML is not supported.Hex supports SSO via OpenID Connect (OIDC). SAML is not supported.learn.hex.tech/docs/administration/sso

What happens to your code

Opt out of training: YesModel providers never train on customer data, and the use of AI session data to improve Hex can be switched off in settings without losing AI features.Depending on your plan, Hex may use data from your AI sessions to improve Hex's AI features. You can opt out of this at any time in Settings > AI &…learn.hex.tech/docs/trust/ai-data-priva…
Data residency: PartlyAn EU multi-tenant region and a single-tenant deployment are offered, but EU on Team is contract-only and the default workspace sits on US infrastructure.Hex offers first-class support for data privacy through initiatives like Workspace AI features opt-out, Bring Your Own Key (BYOK), and geographic…learn.hex.tech/docs/trust/ai-data-priva…
