PrivateBin is best for sharing text via a URL link, especially for developers who want self-hosting options. PingPaste is best for quick cross-device transfers using a 6-digit code or QR scan, with no URL to manage and guaranteed one-time deletion. Both use AES-256 client-side encryption.
What Is PrivateBin?
PrivateBin is an open-source, zero-knowledge encrypted pastebin. You paste text, it encrypts in your browser, and gives you a shareable URL. The server stores only the ciphertext — the encryption key is embedded in the URL fragment, which means the server never sees it. PrivateBin supports configurable expiration, burn-after-reading, and password protection. It can be self-hosted or accessed via public instances.
What Is PingPaste?
PingPaste is also a zero-knowledge encrypted text transfer tool, but its approach is different. Instead of a shareable URL, it generates a 6-digit code. The recipient enters the code on their device and receives the content — which is then permanently deleted from the server. It also generates a QR code for instant mobile scanning. No self-hosting is required, and no account is needed.

When to Use PrivateBin
PrivateBin is the better choice when:
- You need to share code with syntax highlighting
- You want to self-host for complete control over data
- You need password-protected access to a paste
- You want configurable expiry times longer than 10 minutes
- Sharing via a URL is convenient for your workflow
When to Use PingPaste
PingPaste is the better choice when:
- You need to transfer text between your own devices quickly
- You want to use a QR code for instant mobile scanning
- You prefer a 6-digit code over a long URL to share
- You want guaranteed one-time deletion with no configuration
- You do not want to manage or find a PrivateBin instance
- Simplicity and speed matter more than advanced features
The key difference: PrivateBin gives you a URL to share — which can be forwarded, bookmarked, or accessed multiple times until it expires. PingPaste gives you a 6-digit code that works exactly once and then the data is gone. Different tools, different philosophies.
What About Privnote?
Privnote is another popular option that offers self-destructing notes via URL. Unlike PrivateBin and PingPaste, Privnote does not use client-side encryption — the server can theoretically read your content. It is convenient but not truly zero-knowledge. For anything sensitive, either PrivateBin or PingPaste offers meaningfully stronger privacy.
The Verdict
Both tools are excellent at what they do. If you are a developer who wants a paste tool with self-hosting, syntax highlighting, and flexible expiry — PrivateBin is the right choice. If you want the fastest possible encrypted transfer between two devices with no URL management, guaranteed one-time deletion, and a QR code — PingPaste is the better fit.
Many users will find both useful for different situations. They solve related but distinct problems.
