n8n-nodes-stacktree

An n8n community node for Stacktree — the publish primitive for the HTML your agents make. Publish a page to a private, unguessable URL, gate it behind a password or a client's email domain, expire or burn it, and read the feedback viewers leave on it.

Works as a regular workflow node and as a tool inside n8n AI Agent workflows (usableAsTool).

Why this over a generic static host

Stacktree is private by default and built for agent-made deliverables:

• Private-by-default unguessable link, X-Robots-Tag: noai on every page. Opt into a public slug only when you want one.
• Gating a password, or an email-domain gate where the viewer proves they own an @yourclient.com address via a magic link, no account.
• Lifetime control expiry, or burn-after-read (the page deletes itself after the first open).
• A pre-flight secret scan that can block a publish carrying a leaked API key.
• The feedback loop viewers annotate the page in place; you read the annotations and resolve them. No competitor in this category exposes this.

Installation

In n8n: Settings → Community Nodes → Install, then enter n8n-nodes-stacktree.

Credentials

Publishing works with no credentials — the link is anonymous, expires in 24 hours, and the response includes a claim_token you can use to adopt the page into an account later.

Add a Stacktree API credential (an API key from app.stacktr.ee) to make links permanent and unlock every other operation: update, get, list, delete, gating, and feedback.

Operations

Site

Operation	What it does
Publish	Upload HTML (text) or a file/zip (binary) and get back a private URL. Options: password, public slug, expiry, burn-after-read, feedback toolbar, PII scan.
Update	Replace the content at an existing URL in place. The URL does not change.
Set Options	Change gating and lifetime: password, email-domain gate, expiry, public slug, feedback toolbar, title. Only the fields you add are changed.
Get	Fetch a site's metadata.
Get Content	Return the exact stored HTML, so you can edit it and Update in place.
List	List every site owned by the API key.
Delete	Permanently delete a site.

Feedback

Operation	What it does
List	Read the annotations viewers left via the on-page toolbar (unresolved first).
Resolve	Mark a feedback item addressed after fixing the page, with an optional note.

The full loop, entirely in n8n: Publish with the feedback toolbar on → viewer annotates → Feedback: List → Update the page → Feedback: Resolve.

Example: publish a Claude artifact privately

• A previous node produces HTML (e.g. from an AI model).
• Stacktree → Site → Publish, Content Source HTML Text, map the HTML in.
• Under Options, set a password and Expiry 168.
• The node outputs { url, id, unlisted_token, expires_at, ... } — send url on to Slack, email, wherever.
