The Static.app alternative that is private by default.

Static.app is a polished static host that recently added an MCP server and an API. Stacktree is the inverse: private-by-default hosting built around the agent publish primitive, with unguessable URLs and replace-in-place across iterations.

What is the best Static.app alternative?

Stacktree, when the publisher is an AI agent. Static.app is a human-first static host with agent access bolted on, where sites are public by default and passwords are optional. Stacktree treats the agent tool call as the primary publish path: every URL is private and unguessable by default, and the same URL replaces in place as the agent revises the content.

Where Static.app fits

Static.app is a mature, well-built static host for people who manage their own sites. It shines when a human is in the loop: a live in-browser code editor, built-in form handling, a desktop sync app, analytics, and one-click deploys. If you are hand-building a landing page or a portfolio and want to tweak it in the browser, that toolset is hard to beat.

Where Stacktree differs

Stacktree starts from a different premise: the agent is the author. You wire Stacktree in as an MCP server, and the agent publishes HTML with a single tool call, getting back a private URL it can gate and replace on its own. Static.app added MCP and an API to a human-first product; Stacktree was designed around the agent loop from the first commit.

  • Private by default. Every URL is unguessable and acts as the credential. Static.app is public-by-default with optional passwords.
  • Replace-in-place. One URL per artifact, updated via update_site as the agent iterates, so the link you shared yesterday shows today's version.
  • Deeper gating. Email-domain gate with magic-link verification, plus optional end-to-end encryption where the server only ever sees ciphertext.
  • Flat pricing. $0 / $8 / $19, never per-seat.

When to pick which

Pick Static.app if a human edits the site and you want an in-browser editor, forms, and sync. Pick Stacktree if an AI agent produces the HTML, it should be private the moment it exists, and you want one stable URL the agent updates in place.

FAQ

Frequent questions

What is the difference between Stacktree and Static.app? +
Static.app is a static-site host for humans that recently added an MCP server and an API. Stacktree is built the other way round: the AI agent is the primary publisher, every URL is private by default, and the same URL replaces in place as the agent iterates. Both host static HTML; only one is shaped around the agent loop.
Does Static.app support AI agents and MCP? +
Yes. Static.app added an MCP server, a REST API, and a chat-based assistant in 2026. The difference is positioning: Static.app bolts agent access onto a human-first hosting product, while Stacktree treats the agent tool call as the primary way content arrives.
Is Static.app private by default? +
No. A Static.app site is published to a public URL, with password protection available as an option you turn on. Stacktree inverts that default: every link is an unguessable URL that acts as the credential, and you add a password or email-domain gate only if you want a second layer.
Can my agent publish to it directly? +
Both let an agent publish via MCP or API. With Stacktree the agent also gets replace-in-place (update_site keeps the URL stable across revisions) and per-link controls it can set itself: password, email-domain gate, and expiry, each as its own tool call.
How does pricing compare? +
Stacktree is flat-rate: Free at $0, Pro at $8/mo, Agent at $19/mo, with no per-seat fees. Static.app uses tiered subscriptions for storage and advanced features. For a team publishing agent output, Stacktree is predictable and usually cheaper.
Does Stacktree have a live code editor like Static.app? +
No, and that is deliberate. Static.app offers an in-browser editor for hand-editing a site. Stacktree is file-in, URL-out: the agent writes the HTML and publishes it. If you want to edit in the browser, Static.app is the better fit; if the agent is the author, Stacktree is.
