Agent-native publishing

From an HTML file
to a private link.

Publish a prototype, plan, or one-off tool in seconds. It starts private. Share it only when you choose.

Open Instant →Connect Claude
01

Private first

Only you can open a new site until you publish or invite an email.

02

Agent native

A small API and CLI make publishing as easy for an agent as for a person.

03

Just the file

No repository, build, container, or release pipeline between you and the URL.

Connect Claude

MCP = tools for your agent.

Add Instant as a custom connector once, complete the browser sign-in, and Claude can publish and manage sites for you. No marketplace, terminal, API key or configuration file is required.

Your first Instant

Try this prompt

Create a visual project decision brief from my notes. Use any Instant theme and domain available to me, publish it privately, and give me the link.
Everyone can start

One connector. The right workspace.

New public accounts can publish privately and use an inst.pub address. Team membership can unlock a shared catalogue, approved brand themes and custom HopsHQ or Eposability domains. Instant tells the agent what your account is allowed to use.

Codex

Add the MCP server

codex mcp add instant --url "https://instant.ioa.group/mcp"
Then run codex mcp login instant if the browser sign-in does not start automatically.
Claude Code

Add the MCP server

claude mcp add --transport http instant https://instant.ioa.group/mcp
Optional CLI route. Run /mcp, choose instant, and authenticate in the browser. HopsHQ's marketplace is an optional internal shortcut, not a requirement.
