Code
A playground for HTML, CSS and JavaScript, with Markdown and JSON too. The preview runs your code in a sandbox; snippets are encrypted in your browser with your axi0 Key before they leave the page. We hold ciphertext we cannot read.
Unlock your axi0 Key to keep snippets. Without it, what you write stays in this tab until you close it (export still works); nothing is saved.
Open your snippets
New here?
Make a Key in this browser. It downloads as a small file and is shown in full once: keep a copy somewhere safe. Lose it and nobody can open your snippets again, not you, not us.
Your new Key
We just downloaded it as a file, and this is the only time it is shown in full. There is no recovery: keep a copy.
The preview runs your code in a sandbox: it cannot see this page, your Key or your snippets. It can reach the network if your code does (scripts, images, requests to other sites). The editor loads when you first click into a pane; Tab leaves it, Ctrl+Enter or ⌘Enter runs.
