Design beautiful "coming soon" and launch-countdown landing pages — live preview, one-click standalone HTML export.
A focused, dependency-free builder that turns a few form fields into a polished, self-contained launch page: a real ticking countdown, working email capture with a built-in admin panel, animated backgrounds, and social links — all exported as a single HTML file you can drop anywhere.
Coming Soon Builder Pro is a single-page web app for spinning up a launch / pre-launch page in minutes. You edit on the left, watch a pixel-accurate browser-framed preview on the right, and export a fully standalone index.html — inline CSS and JS, no build step, no server, no tracking. The exported page keeps a working countdown, captures emails to localStorage, and ships a hidden subscriber dashboard at ?admin=1.
Everything runs locally. Open index.html from disk or host it on GitHub Pages — both work identically.
- Live preview inside a browser-frame mockup with a real
<iframe srcdoc>— the countdown actually ticks as you edit (debounced re-render). - Four countdown styles — flip cards, clean boxes, minimal text, and animated progress rings, with optional unit labels.
- Launch controls —
datetime-localpicker, visitor-local or fixed-UTC timezone, and a custom "Launched!" message shown at zero. - Email capture — toggle on/off, custom placeholder / button / success copy. Exported pages save subscribers to
localStorageand expose a polished admin panel at?admin=1with CSV export. A live Subscribers: N badge shows the count in the builder. - Five backgrounds — animated gradient, mesh, particle stars, solid, and split — each with primary/secondary color pickers and a dark-overlay slider.
- Social links — add/remove X, Instagram, GitHub, LinkedIn, Discord, TikTok, YouTube, or Website; rendered as a clean icon row.
- Typography & style — modern system-ui, serif (Georgia), or mono font stacks (system fonts only), plus text and accent color controls.
- Advanced — custom CSS, extra
<head>HTML, and an emoji favicon. - Three template presets — Startup Dark, Agency Light, Minimal — plus a one-click realistic example.
- Export & copy — download as
index.html/coming-soon.htmlor copy the full source to your clipboard, with a source preview. - Premium UX — glassmorphism, dark/light themes, autosave, entrance animations, full keyboard support, and a responsive Edit/Preview layout that works down to 360px.
No dependencies, no build tooling.

- Open the accordion panels and edit content, launch date, email capture, background, socials, typography, and advanced options — the preview updates as you type.
- Click Admin in the preview toolbar to test the
?admin=1subscriber dashboard. - Hit Export HTML to download your standalone page, or Copy HTML to grab the source.
- Deploy the exported file anywhere — GitHub Pages, Netlify, an S3 bucket, or your own server.
Your work autosaves to localStorage and is restored the next time you open the builder.
