About Code Share
Code Share is a free browser-based code editor for saving and sharing code snippets. Paste your HTML, CSS, JavaScript, PHP, Python — any of 23 supported languages — and get instant syntax highlighting, line numbers, and one-click download.
Signed-in users get auto-save to the cloud so snippets follow them across devices, plus one-click public share links so they can send code to anyone with just a URL. The recipient sees a clean, syntax-highlighted read-only page they can copy or download.
Anonymous = local only: snippets save to your browser via localStorage and never leave your device. Signed in: snippets sync to your account and you can create public share URLs.
How to use Code Share
Pick a language
Choose your language from the dropdown — HTML, JS, PHP, Python, or any of 23 others. Syntax highlighting adjusts instantly.
Paste your code
Drop your code into the editor. Auto-save keeps it safe locally. Use tabs to keep multiple snippets open at once.
Save or share
Signed-in users click Save to persist to their account, or Share to generate a public read-only URL. Or Download / Copy the code.
Key Features
Syntax highlighting for 23 languages
HTML, CSS, JavaScript, TypeScript, JSX, Vue, PHP, Python, Ruby, Java, C#, Go, Rust, C, C++, Swift, Kotlin, SQL, JSON, YAML, Bash, Markdown, and Plain text — all with GitHub-style coloring.
Auto-save that never forgets
Every keystroke saves locally. Signed-in users get automatic cloud sync every couple of seconds.
Multi-snippet tabs
Keep several snippets open in tabs. Switch instantly, rename inline, close individually.
Public share links
One click to generate a read-only public URL. Anyone with the link sees your code with syntax highlighting. Revoke anytime.
Cross-device sync
Sign in and your snippets follow you — laptop, phone, tablet, all in sync.
Line numbers + Copy + Download
Line numbers update as you type. Copy the whole snippet to your clipboard or download as a file with the right extension.
Common Use Cases
- Share a code sample with a coworker without setting up a repo
- Save frequently-used snippets (regex patterns, config files, boilerplate) for quick access
- Paste code from Stack Overflow / docs into a persistent place before adapting it
- Send a syntax-highlighted preview to a non-technical stakeholder
- Keep language reference examples handy (JSON schemas, SQL queries, curl commands)
- Draft code for a talk, tutorial, or blog post before publishing
- Use as a scratchpad while debugging — try variations without touching your real repo
Security & Privacy
- Anonymous snippets stay on your device — saved only in browser localStorage.
- Signed-in snippets are private by default — only you can see them.
- Share links are opt-in and revocable — snippets are public only when YOU generate a URL.
- Shared pages aren't indexed —
noindex, nofollowprevents Google crawling. - TLS encryption everywhere for data in transit.
- Full account deletion — all snippets go with your account, immediately.
