A lot of what AI agents make gets stuck where it was made: a report in a Claude chat, a dashboard on your laptop, a Cursor mockup with no link to send. Spacesheep, which launched on Product Hunt on 29 October 2026, gives that output a shareable home where other people can comment on it and your agent can revise it.
What it is
Spacesheep publishes what an AI agent makes as a web page it calls a "space". Its homepage puts the idea in one line: "Your AI makes the space; your team reads it, comments on it and builds on it." Each space gets its own address in the form spacesheep.dev/@you/page-name, and you can make it private, link-only or public.
Spacesheep says spaces can be reports, dashboards, designs, mockups and small apps. The makers are Michael Makarov (founder) and Rohan Chaubey, and the listing showed a #3 day rank with 254 points when we checked on 30 October. The product predates the launch: its changelog goes back to 5 July 2026, and the latest entry is dated 28 October.
Who it's for
Spacesheep suits solo builders and creators who make things with agents and need someone else to look at them: a consultant collecting client comments on an AI-drafted report, a founder sharing a Claude Code dashboard with an investor, or a designer getting feedback on a Cursor mockup. It fits best if you switch between Claude, ChatGPT and a coding agent and want that output in one place. Our review of Claude Cowork covers the case where everything happens inside one vendor's tools.
What it actually does
Publishing. Spacesheep connects to your agent through an MCP server. Its getting-started page says you ask for a page, such as a metrics report or an architecture overview, and it "publishes to a private, shareable URL". Its tools include deploy, edit, share_space, screenshot and download_pdf, and a command-line tool covers agents that can't sign in through a browser.
Line-level comments and AI revisions. The homepage says you can "comment on the exact line". Writing @spacesheep in a comment asks Spacesheep's AI to fix the space, and the company says this happens "while everyone watches". The Free, Pro, Max and Team plans all include comments, reactions and version history, according to the plans page. The AI runs on Spacesheep's own model allowance, so no API key is needed, though you can add your own to avoid the cap.
Many agents, one space. Spacesheep says Claude Code, Codex, Cursor, ChatGPT and Grok can all publish to the same space, and the plans page also lists Gemini. The setup page covers Claude, ChatGPT, Claude Code, Codex and Cursor, but not Gemini.
Owning your files. The homepage says every space and version can sync to your Google Drive or GitHub. The plans page lists daily Drive backups only on paid plans and doesn't mention GitHub, so treat backups as a paid feature.
Extras. Spaces can be sent for signature, Max adds "Streams" for live server data plus voice control, and a "Worker mode" for apps with server-side code is invite-only.
A worked example (illustrative). You ask Claude Code to build a monthly client report and publish it as link-only. Your client comments on a line in the churn section: "can we split this by plan?" You reply "@spacesheep add a by-plan breakdown here", the AI edits the space, and a new version appears, with the old one still in the history. We haven't tested this hands-on, so check how well the edits hold up on your own content.
Pricing (as of 30 October 2026)
All prices are in US dollars and billed monthly. The plans page lists no annual discount.
Plan | Price | Main limits and features |
|---|---|---|
Free | $0 | 200 files and 25 MB per deploy; agent on Grok 4.7 and Claude Haiku 5.5 (7M tokens a month); 60 web searches a day; 15 signature sends a month |
Pro | $4.50/mo | 12,000 files and 2 GB per deploy; adds Gemini and Claude Sonnet 5.5 (20M tokens a month); daily Google Drive backups; session hooks for Claude Code, Codex and Antigravity |
Max | $9/mo | 50M tokens a month plus 8M on Claude Opus 5.5; voice control; Streams live data; Stacks |
Team | $10 per member/mo | Everything in Max for each member, shared tools and team docs |
Enterprise | Quote | SAML single sign-on, SCIM, your own domain, policies such as "no public links", audit log |
The FAQ says each allowance has hourly, daily and 30-day limits but publishes only the monthly figures. At these prices, cost isn't the main reason to hesitate.
Getting started
We estimate a first session at about 20 minutes:
Connect one agent. For Claude Code, run the
claude mcp addcommand on the start page, restart, then type/mcpto sign in. In the Claude apps, addhttps://mcp.spacesheep.dev/mcpas a custom connector under Settings → Connectors. ChatGPT needs Developer mode turned on first. Claim your @username at first sign-in, since it becomes part of every link.Publish something real that you'd otherwise send as a PDF, such as last month's numbers. Keep it private.
Test the comment loop. Switch to link-only, open it in a private window, leave a line comment, then tag @spacesheep with a specific change. Check the edit and that the previous version survives.
Upgrade only if you hit a limit. The free tier is enough to judge whether the workflow sticks.
Alternatives
Claude artifacts sharing. Anthropic says artifacts start private and, on paid plans, can be shared with anyone with the link, invited people, or (on Team and Enterprise) your organisation, and people with Commenter access can leave comments. Pick this if Claude is your only assistant. Pick Spacesheep if output comes from several agents.
ChatGPT canvas. OpenAI added sharing to canvas in February 2025, and recipients can view, interact with or edit what you share. Pick it for quick drafts you made in ChatGPT and want someone to take further.
GitHub Gist or a Vercel deploy. A gist or static deploy is free and under your control. GitHub notes that secret gists aren't private, and Vercel's comments on preview deployments are free on all plans but require every commenter to have a Vercel account. Vercel's Hobby plan is for personal, non-commercial use. Pick this route if you want hosting you own and don't need AI revisions from comments. For apps with a database and logins, see our review of Blink.new.
Limitations
Brand new. The public changelog starts in July 2026 and the Product Hunt launch was this week. There's no track record yet.
The platforms are building this too. Claude already offers shared artifacts with comments, and ChatGPT lets you share canvases. One Product Hunt commenter saw cross-platform support as the only difference from Claude Artifacts, which is the fair question to ask. We made a similar point about Notion Auto: the tool your work already lives in often wins.
Opaque allowances. Hourly and daily token caps exist but aren't published.
Hidden agent instructions. The homepage contains text telling visiting AI agents to run deploy and login commands. If you point an agent at the site, watch what it runs.
Not hands-on tested. This review relies on Spacesheep's pages and its Product Hunt listing.
Verdict
A cheap, well-designed way to share agent output and keep iterating on it, but it's brand new and the AI platforms are building their own sharing features.
At $4.50 to $9 a month, Spacesheep turns scattered agent output into links with line comments, AI fixes and version history, a real help if you send AI-made work to clients. Its strongest case is working across several agents, because Claude and ChatGPT already handle sharing inside their own apps. Start on the free plan, run one real client deliverable through the comment loop, and pay only if it saves you a round of emails.
