# Rendering HTML from a gist or repo

Everyone hits this once. You have an HTML report in a repo — a coverage
summary, a profiling output, a chart your script wrote. You push it, open the
link, and GitHub shows you the source code.

That is deliberate. `raw.githubusercontent.com` serves everything as
`text/plain` with `nosniff`, precisely so nobody can host executable HTML on a
GitHub domain. No repo setting turns it off.

## The three usual workarounds, honestly

### htmlpreview.github.io

Paste your raw URL after `https://htmlpreview.github.io/?` and it proxies the
file with the right content type, rewriting relative references as it goes.
For a single small public file this is the fastest thing available and worth
keeping in your bookmarks.

Where it stops:

- **Public only.** The proxy fetches over the internet; a private repo 404s.
- **Multi-file bundles are fragile.** Every relative reference becomes another
  proxied fetch, and anything the rewriter does not recognise breaks.
- **Rate limits and size.** It is a free community proxy, not infrastructure
  you can depend on for a link you are pasting into a leadership channel.
- **No access control, no comments, no versions.** It is a viewer.

### GitHub Pages

A real answer for a real site: build, deploy, public URL, custom domain. For a
single report it is a lot of ceremony, and private Pages is a paid-plan
feature with no review layer attached. Full tradeoff in
[GitHub Pages alternatives](/alternatives/github-pages-alternatives).

### Commit a screenshot instead

The one everybody actually does. It works, and it destroys every number in the
report — nothing is checkable, nothing is searchable, and the interactive
chart becomes a picture of a chart. See
[stop screenshotting reports](/stop-screenshotting-reports).

## The alternative: publish the file, keep the access rules

If what you want is _this HTML, at a URL, for these people_, the repo was
never the right container. Publishing takes one motion:

- Drag the file — or the whole folder, or a zip — into
  [the app](https://commareports.com/), or `POST` it from a script or
  [an agent over MCP](/docs/mcp).
- Pick visibility: private, team, email-domain-gated, named reviewers, or
  public. Identity, not a shared password.
- Get anchored [comment threads](/comment-on-html) on the rendered page, and a
  revision each time you republish to the same id — so the link in your README
  never goes stale and never changes.

Scripts run, sandboxed (`allow-scripts`, no `allow-same-origin`), which is the
same reason GitHub refuses to render your file — except the sandbox is the
product's job rather than your repo's problem.

## How to choose

- **Quick look at a public single-file demo?** htmlpreview, every time.
- **A site with routes?** GitHub Pages, Netlify, or Cloudflare Pages.
- **A report — private, versioned, and something people should respond to?**
  Publish it: [share an HTML report](/share-html-report).
