What Is a Pastebin? A Guide to Sharing Code & Text with PasteBox
Last updated: July 1, 2026
A pastebin is an online tool for storing and sharing plain text or source code. Instead of emailing a file or pasting a huge block into chat, you paste your content once, get a short link, and share it. PasteBox is a free, fast pastebin with syntax highlighting, privacy controls and instant sharing.
What is a pastebin used for?
- Sharing code snippets, logs, stack traces and config files with teammates or in forums.
- Getting help: post an error and a reproducible snippet, then share the link.
- Sending one-time secrets with burn-after-read or encryption.
- Publishing notes, Markdown documents and AI prompts.
How do I share code on PasteBox?
- Open the home page and paste your text or code into the editor.
- Leave the language on Auto-detect or pick one for syntax highlighting.
- Choose expiration and visibility, and optionally add a password or encryption.
- Click Create and share the short link you get back.

Frequently asked questions
- Is a pastebin the same as GitHub Gist?
- They overlap: both share snippets by link. Gist is tied to a GitHub account and Git history; a pastebin is optimized for fast, often anonymous one-off sharing with expiration, passwords and burn-after-read.
- Can I share code without an account?
- Yes. On PasteBox you can create a paste as a guest and share the link immediately. A free account adds longer expirations, private pastes and a dashboard.
- How do I keep a paste private?
- Set the visibility to Unlisted (link-only) or Private (account-only), add a password, or enable client-side encryption so the server never sees the plaintext.
