# Dropbox Stopped Rendering HTML Files — What To Use Instead

> Dropbox disabled HTML rendering on shared links in 2017. Why your report now downloads instead of opening, why the ?raw=1 trick no longer works, and how to publish the file as a real URL.

# Dropbox stopped rendering HTML files

You dropped `report.html` into Dropbox, copied the share link, and the
person who opened it got a Dropbox preview page with a download button —
not the report.

Nothing is misconfigured. The feature was removed.

## What happened

Dropbox used to render HTML shared links in the browser, and a lot of
people used it as a zero-effort static host for one-off pages and reports.
It was withdrawn in September 2017 for Basic and Pro accounts (Business
accounts followed), as an anti-abuse measure — the same rendering that
served your coverage report served a convincing fake login page just as
well.

The two workarounds people still post don't bring it back:

- **`?dl=1`** forces a download. That is what it was always for.
- **`?raw=1`** returns the file bytes, but not with the headers a browser
  needs to treat the response as a page it is visiting. You get a download
  or a plain-text dump, not a rendered document.

The old **Public folder**, which did serve files directly, was retired for
all accounts around the same time.

## The second problem, which storage was never going to solve

Most tools that emit "an HTML report" emit a **folder**: `index.html` plus
a sibling directory of CSS, JavaScript and JSON. Playwright, Allure,
`genhtml`, `nbconvert`, Sphinx and Storybook all do this.

Share just the `.html` and every reference in it resolves to nothing —
that's the blank or half-styled version of the same failure. See
[why the report lost its CSS](/html-report-broken-css).

And even in the best case, you have shipped a **copy**. Everyone who wants
to discuss it has their own download, and the only way to say "this number
is wrong" is a screenshot with an arrow on it.

## The fix: publish it, don't store it

Drag the file — or the whole output folder, or a zip — into
[Comma](https://commareports.com/):

- `index.html` becomes the report body.
- Sibling assets upload with it and relative `src`/`href` references are
  rewritten to the uploaded copies.
- Scripts run inside a sandboxed iframe (`allow-scripts`, no
  `allow-same-origin`), so filters, sortable columns and charts keep
  working. See [interactive HTML reports](/interactive-html-reports).

One URL, and it opens on a phone too — which the Dropbox app never did for
HTML.

## Who can see it

Per report: private, team, anyone signed in at your domain, or anyone with
the link, with view / comment / edit rights for link holders. Full model in
[sharing & access control](/docs/sharing).

This is per-report rather than per-folder, which is usually what you
actually wanted from the Dropbox share dialog anyway.

## If the report regenerates, publish from the job

```bash
curl -fsS -X PATCH "https://commareports.com/api/v1/reports/$REPORT_ID" \
  -H "Authorization: Bearer $COMMA_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d "$(jq -n --rawfile html report.html '{html: $html}')"
```

`PATCH` one saved id and every run appends a revision at the same URL, so
the link you pasted in a doc six months ago still shows the current
report. See [publishing from CI](/docs/ci) and
[API tokens](/docs/api-tokens).

## Then: comment instead of screenshot

Once it has an address, feedback goes on the report — select the cell,
leave a thread, and it stays anchored across revisions. See
[commenting on HTML](/comment-on-html).

## Limits

- **Entry HTML: 5 MB.** Assets: 25 MB per file, 250 MB and 500 files total.
- **Scripts run, sandboxed** — no same-origin access to your session.
- **60 requests/minute per token.**

## Try it

Comma is free — unlimited reports, unlimited commenters, unlimited
revision history.
