When to share code with NullPaste

- Attaching a code block to a support ticket without uploading a file
- Sharing a build config or deploy script with a teammate who does not have repo access

Frequently asked questions
- What is the easiest way to share code online?
- Open nullpaste.com, paste your code, and click Create Paste. You get a shareable link with syntax highlighting in under 10 seconds — no account, no sign-up, no configuration required.
- How do I share code without GitHub?
- NullPaste lets you share code with a link without any GitHub account or Git knowledge. Paste your code, click create, and share the URL. Syntax highlighting is applied automatically.
- Can I share code privately online?
- Yes. Add a password to restrict who can open the link, or enable end-to-end encryption so only someone with the complete URL can decrypt the content. For single-recipient shares, burn-after-read means the paste is deleted after the first view.
- Does NullPaste support my programming language?
- NullPaste uses Shiki for syntax highlighting, supporting 100+ languages including JavaScript, TypeScript, Python, Go, Rust, Java, C/C++, SQL, Bash, YAML, Markdown, Dockerfile, and many more. The language is auto-detected — you can override it manually if needed.
- Is NullPaste better than GitHub Gist for sharing code?
- It depends on what you need. NullPaste requires no account, no Git knowledge, and adds burn-after-read, password protection, and end-to-end encryption. GitHub Gist adds version history and comments. For quick, private, accountless code sharing, NullPaste is faster and simpler.
- How long does a shared code snippet last?
- You choose: 10 minutes, 1 hour, 1 day, 1 week, or never. Pastes set to never expire include a delete code you can use to remove them manually. All pastes auto-delete when their timer runs out.
