Your template, made personal.

Upload one HTML file or a ZIP up to 10 MB with index.html at the root. Bundle styles and scripts locally. Images can be included in the ZIP.

Editable details

Headings, paragraphs, buttons, image sources, video posters, and root CSS colours are detected automatically. Explicit markers give you control.

<h1 data-edit="text" data-label="Recipient name"
    data-group="Hello" data-maxlength="40">Alex</h1>
<img data-edit="image" data-label="Cover photo" src="assets/photo.jpg">
<p data-edit="date" data-label="Together since">2023-02-14</p>
<style>:root { --primary: #ff4d8d; }</style>

Review your manifest

Rename labels, group related fields, set length limits, lock fields, and change their order. Test a preview before submitting. New versions preserve existing customers' pinned designs.

Interactive moments

<section data-hn-section="Our memories">...</section>
<script>
  // Call after a visitor completes your interaction.
  window.HN?.track('game_complete', 'birthday-candle');
  // Resolved fields are available by their manifest IDs.
  const values = window.__HN__.values;
</script>

A safe little world

Your template runs in an opaque-origin sandbox. It cannot access parent cookies, authentication, or the parent DOM. External network requests and forms posting off-site are blocked. Use local assets and inline scripts. Never collect credentials or sensitive personal information.

Versioning and pricing

Choose a price from ₹0 to ₹999. Published designs are immutable: upload a new version to make changes. Existing gifts stay pinned to the version they purchased.
