# Comma vs Hex: Which Should You Use for Sharing & Reviewing Reports?

Canonical: https://commareports.com/vs/hex

> Hex builds the analysis. Comma renders the HTML, anchors comments, and refreshes it on a cron. A direct, honest comparison for data teams choosing between the two.

# Comma vs Hex

## TL;DR

**Hex is a place to build the analysis. Comma is a place to share it.** Hex
combines SQL, Python, and chart cells inside a notebook environment, and
publishes the result as a data app. Comma takes any HTML — from Hex, from
Claude, from a dashboard export, from an eval harness — and turns it into a
shareable document with anchored comments and scheduled refreshes.

If you need one tool that does both the writing and the sharing, Hex covers more
ground. If you already have the report and need it reviewed, refreshed, or
posted by an agent, Comma is purpose-built for that and is often used
_alongside_ Hex.

## What Hex is good at

**Building the analysis.** Hex's notebook combines SQL cells, Python cells, and
visual chart cells, so a data analyst can query a warehouse, transform the
result, and publish a dashboard without switching tools. The Notebook agent and
Threads agent let non-technical teammates ask questions in plain English and
get back generated analyses. The semantic model in Context Studio gives a data
lead a way to govern what those agents can answer.

If your team starts at the warehouse and ends at a published dashboard, Hex
covers the whole arc — and does it with a real, mature notebook environment.

## What Comma is good at

**Everything that happens after the artifact exists.** Comma starts at the HTML.
You paste it, upload it, post it through the API, or let an agent ship it via
MCP. From there:

- The report renders faithfully inside an opaque-origin sandbox — Comma does not
  reformat, restyle, or re-architect what you generated.
- Anyone with the link can pin an anchored comment to a paragraph or a table
  cell, Google-Docs style. Casual reviewers don't pay per seat.
- A routine re-runs your underlying skill on a cron and posts the new HTML as a
  revision on the same report. Routines run at any cadence on every plan — you
  pay only for the AI compute (BYO AWS Bedrock key, or prepaid credits).
- The same `comma_sk_…` token gates the REST API and the MCP server — your
  Claude Code or Cursor agent is just another collaborator, scoped and
  revocable.

## Where each one wins, in detail

### Building the analysis

**Hex wins.** This is Hex's home turf. You write the SQL, the Python, the
chart, and the layout inside one notebook. Comma does not query a warehouse,
does not execute Python against your data, and does not build dashboards.
Comma is BYO HTML.

### Sharing for review

**Comma wins.** A Hex notebook is a notebook. Even when "published as an app,"
the artifact reads as a Hex object — and the people you most want to comment
(PMs, designers, stakeholders) often won't open a notebook UI the way they
open a Google Doc. Comma's surface is the rendered HTML with an anchored
comment layer outside the iframe. Link-first sharing. Anyone-with-link
identity. No "create a Hex account to leave one comment" friction.

### Scheduled refresh

**Both, with different shapes.** Hex Scheduled Runs are mature, but live behind
the Team plan ($75/seat/month). Comma routines are a feature of every plan —
unlimited, at any cadence — and refresh by re-running the
underlying skill, not just re-executing a stored notebook. Routines also work
on artifacts Hex would never see: a Claude skill, a custom Python report, a
dashboard exported nightly.

### Agent collaboration

**Comma wins.** Comma was built with agents as a first-class collaborator. The
MCP server (Streamable HTTP transport) gives Claude Code, Cursor, and VS Code
agents a typed surface for posting reports, anchoring comments, and replying to
feedback. Tokens are scoped, revocable, and rate-limited. Hex's API is
notebook-centric and not designed as a posting endpoint for arbitrary HTML
output.

### Pricing for review-heavy teams

**Comma wins.** Hex charges per editor. If you have three analysts and twenty
reviewers, you pay for editor seats anyway and the reviewers may live on a
viewer tier with limited interaction. Comma is free — unlimited reports,
unlimited commenters, and unlimited routines on every plan — and never
paywalls the commenters. You pay only for hosted AI compute (prepaid credits)
or bring your own AWS Bedrock key for free. If your bottle
shape is "few producers, many commenters," the math diverges quickly.

### Governance & enterprise readiness

**Hex wins today.** Hex has audit logs, OIDC SSO, single-tenant deployment,
and a HIPAA add-on at the Enterprise tier. Comma is a younger product. SSO,
audit log, and DPA are on the Comma Enterprise roadmap; per-token rate limits,
scoped permissions, and opaque-origin sandboxing are already shipped.

## Who Hex is best for

- Data teams whose primary job is to **build** the analysis from a warehouse.
- Organizations that want governed self-serve BI with a semantic layer.
- Customer-facing embedded analytics where the dashboard is the deliverable.
- Teams with more editors than reviewers.

## Who Comma is best for

- Engineers, analysts, and PMs who **already have the HTML** — from Hex, from
  Claude/ChatGPT/Cursor, from a notebook export, from a custom script.
- Teams with more reviewers than producers, where casual commenters need a doc,
  not a notebook.
- Anyone running a Claude skill on a cron and tired of pasting the output into
  Slack.
- Agent operators who want a scoped, revocable place for an LLM to post its
  work.

## Using them together

The most honest answer for most data teams: **use Hex to build, use Comma to
share.** Wire your Hex notebook into a Comma routine via the API, or export
the rendered HTML and post it to Comma. Reviewers get a faithful document with
anchored comments; the routine refreshes it on a cron; the original Hex
notebook remains the source of truth for the analysis itself.
