Use cases
What people build with Logic Bomb.
Promo banners & flash-sale ribbons
Push a sticky banner to every product page during a flash sale, then yank it the second the sale ends — no deploy required.
Custom event tracking
Drop a JS snippet that listens for clicks on specific selectors and fires events to your warehouse — without touching the host site.
DOM-level experiments
Modify CTA copy, swap hero images, restructure layouts on the fly. Roll back instantly if conversion dips.
On-page help widgets
Inject a contextual help widget that knows which page the user is on. Update copy and behavior without redeploying the host site.
Integration
One tag. Drop it anywhere.
That's the whole integration. Paste this in the <head> of any HTML page, and your code is live.
client-site / index.html
<!-- in the <head> of your site --> <script src="https://logic-bomb.app/api/script/your-slug.js" async></script>

02
Write your code

03
Paste the tag
Drop the <script> tag into the target site. Updates propagate automatically.
FAQ
Questions, answered.
What is Logic Bomb?+
Logic Bomb is a hosted platform for delivering HTML, CSS, and JavaScript to any website via a single <script> tag. Edit your code in the dashboard, hit save, and changes propagate to every page that loads your tag — typically in under 30 seconds.
How is this different from Google Tag Manager?+
GTM is built around tag templates and event tracking. Logic Bomb is built for developers shipping arbitrary code: a real Monaco editor, three independent files (HTML/CSS/JS), and CSS-selector-based DOM injection. It’s closer to a CMS for runtime code than a tag manager.
Where does my code run?+
Your JavaScript runs in the host page's context — full DOM access, full access to globals on the page. CSS is appended to <head>. HTML is injected into the element matching your target selector (default: <body>).
How fast do updates go live?+
Sub-30 seconds globally. We serve your bundle from the edge with stale-while-revalidate caching, so visitors get the cached version instantly while a fresh build downloads in the background.
Is there a free tier?+
Yes — sign up free and create your first script in under a minute. Paid plans add higher request volumes, team seats, and audit logs.
Does it work with single-page apps?+
Yes. The script bundles a tiny mutation-observer that re-runs your HTML injection when the host SPA replaces the matched element, so your code stays mounted across client-side route changes.
Ship your first script in 60 seconds.
