Changelog

Build pages with AI, tweak them visually, and start collecting form data — three big additions in one release.

New Features

AI Page Builder

• Chat to create — describe what you want and Claude builds the HTML for you, right inside the dashboard
• Edit with AI — open the AI panel on any existing page to refine copy, update styles, or restructure layouts through conversation
• New chat button — start a fresh AI conversation at any time without leaving the editor

Visual Editor

• Click-to-edit text — click any text element on your published page to edit it inline
• Spacing toolbar — adjust padding and margins visually without touching code
• Responsive preview — switch between desktop, tablet, and mobile breakpoints to see how your page looks on every screen size
• Delete with undo — remove elements with a single click and bring them back with Ctrl+Z
• Persistent selection — click sections and non-text elements to select and modify them
• Script preservation — your custom JavaScript stays intact when editing visually

Form Collection

• Collect submissions — enable form collection on any page and htmlpub captures every submission automatically
• Forms dashboard — new Forms section in the sidebar to view submissions, see counts, and export to CSV
• Works everywhere — forms are intercepted whether they have an action attribute or not, including inside iframes

Improvements

• Tooltips on page actions — hover over action icons in the pages list to see what each one does
• Consistent dashboard layout — all dashboard sections now share a unified header style
• Dark mode polish — fixed colors and contrast throughout the dashboard for a cleaner dark theme
• Keyboard shortcuts — press Escape to close the Update Page modal
• Slug validation — page slugs now require a minimum of 10 characters

Custom domains are easier than ever, asset uploads no longer choke on large files, and shared links look great.

New Features

Custom Domains with Entri

• One-click setup — connect your own domain with automatic DNS configuration powered by Entri
• Automatic SSL — certificates provisioned and renewed automatically
• Buy a domain — purchase a domain directly from your dashboard without leaving htmlpub
• Plan limits — Free: 0, Starter: 1, Pro: 5 custom domains

Presigned URL Asset Uploads

• create_asset_upload — get a presigned upload URL so Claude can upload files directly instead of encoding them as base64
• complete_asset_upload — confirm the upload and attach the asset to your page
• Eliminates timeouts caused by generating thousands of base64 tokens for images

list_assets Tool

• list_assets — discover all assets attached to a page, including files uploaded through the web UI
• MCP server now exposes 14 tools

Web Upload Page

• Upload images, CSS, JS, and fonts to any page from your browser at /p/{slug}/assets
• Great for adding files that are easier to upload manually, then referencing them from Claude with list_assets

Compact Page Retrieval

• get_page now returns compact HTML by default — large inline blobs (base64 data URIs, long style/script/SVG blocks) are replaced with placeholders
• Fixes "Tool result too large for context" errors on Claude.ai
• Text content is preserved so edit_page search/replace still works

Dynamic OG Images

• Shared links now show a branded 1200×630 card with the page title instead of a generic logo
• Screenshot pipeline generates real page previews when available, with automatic fallback to the branded card

Improvements

• Docs section — MCP Connector and REST API docs are now in a single /docs section with sidebar navigation
• Faster MCP requests — existing sessions skip re-authentication, saving a database query per tool call

Edit pages without regenerating the entire HTML document — Claude sends only what changed.

New Features

edit_page Tool

• Search/replace edits — specify old_text and new_text pairs instead of rewriting the full document
• Batch support — apply up to 50 edits in a single call
• Atomic — if any edit fails (text not found or ambiguous match), nothing is saved
• Dramatically reduces output tokens for small changes like fixing text, updating styles, or changing links

publish_page Tool

• Custom slugs — publish pages at a chosen URL like pages.pubhtml.com/my-portfolio (Starter/Pro plans)
• Upsert behavior — creates the page if the slug is new, updates in-place if it already exists

upload_asset Tool

• File uploads — attach images, CSS, JS, and fonts to any page
• Returns a URL for use in your HTML — no external hosting needed

Improvements

• update_page description now guides Claude to prefer edit_page for small changes
• MCP server now exposes 10 tools (up from 7 in v1.3.0)

Connect your htmlpub account to Claude.ai and publish pages straight from the conversation.

New Features

Claude.ai MCP Connector

• OAuth 2.0 with PKCE — sign in with your htmlpub account via the standard OAuth flow
