Build your Pastebin with AI in under 5 minutes

What is a pastebin?

A pastebin is the simplest possible content-sharing primitive: paste text, get a URL, share it. Developers use them constantly — sharing logs in a Slack thread, sending an error trace to a colleague, pasting a config snippet into a forum reply. Pastebin.com and GitHub Gist dominate the category, but both impose either ads, account requirements, or arbitrary privacy semantics. A self-hosted pastebin solves none of those for free, but it solves something else: control. Your own pastebin can enforce auto-expire by default so stale secrets don't linger; it can refuse to host content over a size threshold so it doesn't become a CDN for malware; it can live on your company's domain so a paste in a Slack thread doesn't redirect to an ad-supported page that someone's IT team will block.

Common features

• Paste form — title, content, language, expiry
• Syntax highlighting based on detected or selected language
• Public / unlisted / private visibility
• Auto-expire on configurable timeline (1h / 24h / 7d / never)
• Raw text endpoint for curl / wget consumption
• Owner token returned at create-time for later edit/delete
• Line numbers and line-level deep-linking
• Optional password protection per paste
• Size cap to prevent abuse
• Search and tag system for non-anonymous use

Real-world examples

Why FloopFloop fits pastebin projects

Pastebins are simple to describe and full of small editorial decisions: what's the default expiry, what's the size cap, do you allow anonymous, what's the abuse policy? Building your own takes those decisions away from a third party. FloopFloop ships a pastebin that respects your team's policy — log-friendly defaults, internal-only visibility, expiry tuned to compliance needs. The infrastructure cost is essentially zero. The trust cost — knowing that a paste shared from your team's pastebin won't end up as a CDN bandwidth bill or an ad-injected page — is high.
