Turn an idea into a website, dashboard, report, or small web tool you can share. Build it in your conversation, or bring something you already made, and publish it with Spacefast.
Keep improving it through chat. Change the content or design, share a preview, choose who can open it, connect your own domain, or restore an earlier version.
Connect your Spacefast account to publish and manage your team’s Spaces.
Use Spacefast from Claude Code, Codex, or Cursor. Each plugin includes focused skills and the MCP configuration its client needs.

npx -y skills@1.5.23 add spacefast/plugins --skill spacefast -g -yAsk your agent: Publish this project with Spacefast.
Anonymous publishes go through the CLI: sf publish needs no account and returns a Live URL plus a claim link. The hosted MCP connection needs browser OAuth before any tool runs. The Claude Desktop bundle runs On-Device MCP and can publish anonymously on its own.
Plugin hooks send no telemetry. The CLI records only install and setup outcomes: agent, method,
outcome, reason code, CLI version, OS, and timestamp. It never sends a machine, user, team, path,
file-content, or credential identifier. Set SPACEFAST_TELEMETRY_DISABLED=1 or DO_NOT_TRACK=1
to disable disclosure and delivery before any event is sent.
Raw events are retained for 30 days and aggregate counts for 90 days. See the privacy policy.
Open Your Spaces from the sidebar or a conversation tab to browse the Space Library. Search, load more Spaces, and select one to see its live URL and dashboard link. Supported hosts can open a Space directly through a library deep link and switch between inline and fullscreen views.
Use the Spacefast composer mention picker, or select a Space and click Add to chat, to include it in the conversation. Removing that attachment leaves it removed. While the library is open, the agent can read its selection, search, and open another Space through the mounted App tools. When a destination is unclear, the agent can show a Space chooser. Hosts with rich forms show descriptions and thumbnails; other hosts use their supported form or a choice in chat.
Plugin settings include Spaces per page (10–50, default 20) and Show Space status (on by default). These settings belong to your user account. Team and service connections use defaults.
On desktop, open an HTML or HTM file with HTML Preview to inspect its preview and edit its source. Save writes the opened file only when the host allows it. Saving does not publish the file. External changes keep your unsaved draft; reload explicitly before replacing it.
Cloud MCP also supports durable event subscriptions for Space build, deployment, channel, and domain changes when the host supports MCP Events. Subscriptions start only when requested; installation does not create a monitor. Features appear only on hosts that support them.
