HTML Code
Paste your own HTML code to embed any third-party widget
HTML Code is a UniLink app for embedding any third-party widget. Input: raw HTML/CSS/JS or an embed code. Output: a hosted page that renders the widget inside a sandbox with safe defaults.
Overview
HTML Code is for the times when no pre-built block fits. Paste any third-party widget — Calendly, Typeform, Cal.com, Mapbox, custom dashboards — and the page renders it. Sandboxed for safety, mobile-responsive by default, and styled to match your UniLink theme.

✓ Best for
- Embedding third-party widgets (Calendly, Typeform, etc.)
- Custom interactive demos
- Tracking pixels or scripts you control
- Advanced users with specific design needs
✗ Not the best fit for
- Most use cases — pre-built apps cover them faster
- Untrusted code from random sources (security risk)
- Heavy server-side logic — use a real backend
