Your HTML file, a link in one click.
An AI wrote a report to your disk, or you built a page on localhost. Click the sheep and it’s a spacesheep page with its own link: private until you share it, with comments, and every version kept.
Works on files from your computer, local dev servers, and any page you can open.

Allow your files, click the sheep
In the extension’s Details, turn on Allow access to file URLs for files on your computer. Then click the sheep on any HTML page. The first time, you approve the connection on spacesheep.dev, once.
The Chrome Web Store listing is on its way; once it’s live, this is one click.
What it reads, and where it goes.
- Only when you click it, and only the tab you click it on. Never other tabs, your history or your cookies.
- Only the page and its folder: the files it loads from there and below. Never anything above it, and never the pages it links to.
- Only to spacesheep. No analytics, no other server.
- A connection you can end. You approve it once on spacesheep.dev; it can publish but can’t create keys, and Disconnect or Settings ends it.
- Open source, so you can read every line: github.com/spacesheep-dev/spacesheep-extension.
Asked often.
What does the extension do?
It publishes the HTML page in your tab to your spacesheep account and opens it at its own link, spacesheep.dev/@you/page. It brings the images, stylesheets, fonts and scripts the page loads from its own folder.
Does it work with HTML files on my computer?
Yes, that is what it is for: a report an AI wrote to your disk, an export, a page you built. Chrome asks for one switch first, “Allow access to file URLs” in the extension’s details, and the extension takes you there the first time it needs it.
Who can see the page?
Only you, until you share it, unless you chose a different default for new pages in Settings. Share it with names, your team, or anyone with the link, and they can comment on it from any phone.
What happens if I click it again on the same file?
It updates the same page with a new version, so the link you already sent shows the new one. Every version is kept. If nothing changed, it says the page is already up to date.
What about pages that are drawn by JavaScript?
A file from your computer is copied as written, scripts included, so it runs on spacesheep the way it ran on your disk. A web app whose words are all drawn by its scripts is copied as the tab shows it, without those scripts.
What does it read, and where does it send it?
Only the tab you click it on, only when you click it, and only that page plus the files it loads from its folder. It sends them to spacesheep and nowhere else. It has no analytics, and its code is open source.
Is it free?
Yes. The extension is free and open source (MIT), and publishing works on spacesheep’s free plan.
Which browsers does it work in?
Chrome. Other Chromium browsers, such as Edge, Brave and Arc, load the same extension from the zip, but we test it in Chrome.
Can my AI agent publish without it?
Yes. Claude, ChatGPT, Codex, Cursor and other agents publish directly through spacesheep’s connector or its command line, with no browser involved. The extension is for a page that is already open in front of you.
