Short answerPublish the HTML file, with its images and styles, to a host that serves it as a page, then share the link. Overto keeps the page behind your workspace sign-in, lets reviewers comment on it, and keeps every version.
Why an attachment doesn’t work
Sent as an attachment, an HTML file is something to download and open from disk. The recipient has to trust the file, find it and open it in a browser. Anything the page loads from beside it, such as images, a stylesheet or a second page, is missing unless you zip the folder. And feedback comes back as screenshots and messages that point at “the chart near the top”.
A link fixes all three: the page opens in the browser, its files travel with it, and comments can sit on the page.
Your options
| How | Opens as a page | Who can see it | Comments | |
|---|---|---|---|---|
| Attach the file | Email, Slack, Teams | The recipient saves it and opens it from disk. Images, CSS and other pages beside it don’t come along unless you zip them. | Whoever gets the message | No |
| Google Drive[1] | A Drive share link | Google ended web hosting in Drive in 2016, so the file isn’t served as a web page. | People you share with | Not on the page |
| Netlify Drop[2] | Drag in a folder, ZIP or HTML file | Yes, at a public link by default; password or login available | Anyone with the link | On Deploy Previews, through the Netlify Drawer |
| Tiiny Host[3] | Upload an HTML file or a ZIP | Yes, at a public link; password from the Solo plan | Anyone with the link | Feedback mode from the Tiny plan |
| Your AI tool’s sharing[4][5] | Claude Code artifacts, Cursor canvases and others | Yes, inside that tool’s viewer | Depends on the tool’s plan and organization | Claude Code artifacts: yes, for organization shares |
| Overto | From your agent over MCP, or your browser | Yes, including multi-page sites with working links | Your workspace by default, or anyone with a public link | Yes, on passages and elements, plus drawings |
For public hosting on your own domain, a host such as Netlify Drop or Tiiny Host is the better fit; see Netlify Drop and Tiiny Host compared with Overto. For the AI tools’ own sharing, see AI artifact sharing compared.
Publish from your agent
- Add
https://mcp.overto.work/mcpto your agent host as a remote MCP server and sign in with OAuth (setup). - Ask the agent to publish the page to a project, for example: “Publish report.html and its assets folder to Overto in the launch project.”
- The agent calls
overto_publishand sends the page with its files, up to 25 MiB each on Free and larger on Enterprise. - It returns the link and the version. Paste the link into Slack, Teams or email.
Publish from your browser
In your workspace, choose the files or a whole folder, pick a project and publish. A folder keeps its internal paths, so a page and its assets stay together. The browser and your agent share the same per-file limit.
Keep it private, or make a public link
A page opens only for people signed in to your workspace, and only if the project allows it. Choose the whole workspace, the people and teams you grant, or only you. When someone outside needs to read it, anyone who can manage and publish to the project can turn on a public link for a website or Markdown document. The public link shows the current page and its files; comments, source, drafts and older versions stay private. Access & sign-in has the details.
Share a multi-file site
Publish the whole folder as a static website. It runs in its own sandboxed frame. Links between its pages stay in the viewer, a link to a folder opens that folder’s index.html, and links with target="_blank" open in a new tab. Reviewers can step through the pages and comment on each one.
Review and revise
Teammates select text or an element to comment, mention someone, or draw on the page. When you’re ready, choose Copy for agent and paste it into your agent. It reads the open threads and drawings, publishes version 2 on top of the version you reviewed, and replies in each thread. Version 1 stays in history.
Frequently asked questions
How do I share an HTML file as a link?
Publish it to a host that serves it as a web page, then send the link. With Overto, your agent or your browser publishes the file to a project, and teammates open the link after signing in with Google. For people outside the workspace, turn on a public link. Publishing & versions.
Can I share an HTML file with images?
Yes. Publish the HTML file together with its images, styles and scripts, keeping the folder structure. Relative paths keep working, and a link to a folder opens that folder’s index.html.
How do I share an HTML file in Slack or Teams so it opens in the browser?
Post a link instead of the file. Publish the page to Overto and paste its link; teammates click it and the page opens in their browser behind your workspace sign-in.
How do I share an HTML file from Claude, Codex or Cursor?
Connect Overto to your agent as a remote MCP server and ask it to publish the page. It sends the files, gets back a link and a version number, and can later read your team’s comments and publish the next version. Connect your agent.
Can I share an HTML file for free?
Yes. Overto’s Free plan includes 250 MB of storage, files up to 25 MiB, up to 3 members and 25,000 public-page reads a month, with no credit card. Pricing.
Will a public link show up in Google?
Overto public links ask search engines not to index the page. Comments, editable source, drafts and older versions stay private.
