CopyPaste is a free online pastebin for sharing code and text snippets securely. Create paste links with auto-expiration, burn-after-read, syntax highlighting for 50+ languages, and no account required. Unlike other pastebin services, CopyPaste prioritizes security and privacy. Every paste can be set to auto-expire after a custom time period (from 5 minutes to 1 month) and optionally burn after the first read — ensuring sensitive data doesn't linger online indefinitely. The tool supports syntax highlighting for all major programming languages including JavaScript, Python, PHP, Java, C++, Go, Rust, SQL, HTML, CSS, and many more. Highlighted code is easier to read and share with teammates, in bug reports, or on forums. Rate limiting and content scanning protect the service from abuse. There are no account requirements — just paste, set your options, and share the link. Common use cases include sharing code snippets with teammates, posting code in bug reports, sharing configuration files securely, creating temporary notes with auto-expiration, sharing sensitive data with burn-after-read, and collaborating on code without setting up a repository.
