NullPaste

The best pastebin for developers

Share code, configs, logs, and diffs with a clean link. Syntax highlighting for 100+ languages, burn-after-read, end-to-end encryption, and no account required.

NullPasteis built for the way developers actually share things — fast, anonymous, no account friction. Syntax highlighting for 100+ languages, expiry so stale snippets don't linger, and end-to-end encryption for anything sensitive.

  1. Open NullPaste — no setup, no account

    Go to nullpaste.com. No GitHub account, no npm install, no config. The editor is ready immediately.

  2. Paste your code, config, or log

    Drop in any snippet, Dockerfile, YAML config, stack trace, or terminal output up to 1 MB. Syntax highlighting is applied automatically.

  3. Lock it down (optional)

    Set an expiry, add a password, turn on burn-after-read, or enable end-to-end encryption for sensitive code or credentials. No option requires an account.

  4. Share the link

    Copy the URL and post it in Slack, Discord, a PR comment, a Jira ticket, or anywhere else. Your team sees fully highlighted code with no login required.

Developer use cases

  • Sharing in Slack / Discord — paste a snippet, post the link, keep the chat readable
  • Code review — share a diff or isolated function without pulling up a full PR
  • Stack traces and logs — drop a full traceback into a support ticket without attaching a file
  • Config files — share a Dockerfile, nginx config, or CI YAML with teammates who lack repo access
  • One-time secrets — API keys and tokens via burn-after-read + end-to-end encryption; the value self-destructs after the recipient views it
  • Sensitive code snippets — proprietary algorithms or private configs encrypted in-browser before they touch the server

Frequently asked questions

Why do developers use NullPaste over GitHub Gist?
NullPaste requires no GitHub account, works in under 10 seconds, and adds features Gist does not have: burn-after-read, end-to-end encryption, password protection, and custom expiry. For quick, private, accountless code sharing it is faster and simpler.
Can I share API keys or secrets safely?
Yes. Enable end-to-end encryption (content encrypted in your browser before it reaches the server) and burn-after-read (paste deleted on first view). Together these ensure the secret cannot be read by the server and disappears after one use.
Does NullPaste support auto-detected syntax highlighting?
Yes. Syntax highlighting is powered by Shiki and the language is detected automatically from your code. You can override the detection by typing the language name in the Language field (e.g. typescript, go, dockerfile, hcl).
Does NullPaste have an API?
NullPaste has a public raw endpoint at /raw/:id that returns the paste as plain text — useful for scripts that need to fetch paste content programmatically. A full REST API is not available at this time.
Can I use NullPaste for sharing stack traces?
Yes. Stack traces, logs, and terminal output are plain text — paste them in, set an expiry, and share the link in a support ticket or issue. The recipient sees the full output without needing to download a file.
Does NullPaste store my IP address?
No. Raw IP addresses are never written to any database or log. Rate-limiting uses a one-way HMAC-SHA256 hash — the original address cannot be recovered. There is no record linking your identity to a paste.
