Email obfuscation playground
Compare several ways to publish a contact address without making it quite so trivial to scrape. This page generates copyable snippets, shows what humans will see, and calls out the tradeoffs instead of pretending one trick solves spam forever.
What makes this useful
- Visible-text options are readable and work without JavaScript, but humans must retype the address.
- Entity-encoded HTML keeps the address clickable and defeats only basic text scraping.
- JavaScript-built links hide the raw address from the initial HTML, but they fail if JavaScript is blocked.
- A noscript fallback matters if you choose the JavaScript route.
Quick chooser
| Method | Best when | Watch for |
|---|---|---|
| Visible text disguise | You want the simplest no-script fallback and do not mind users retyping. | Copy-paste friction and no one-click mail app launch. |
| HTML entities | You want a clickable link with minimal markup changes. | Many scrapers decode entities, so the protection level is limited. |
| JavaScript-built link | You control the page and can accept a JavaScript dependency. | No link at all if scripts fail unless you keep a noscript fallback. |
