Quick Picks

Use Case	Best Choice	Why
Maximum security	PrivateBin	Zero-knowledge encryption — server never sees plaintext
All-in-one sharing	MicroBin	Pastebin + file sharing + URL shortener in one tool
Team code sharing	Opengist	Git-backed snippets with syntax highlighting
Minimal footprint	MicroBin	Single 10 MB binary, no database

Why Self-Host a Pastebin?

Public pastebins (Pastebin.com, GitHub Gists) store your data on third-party servers with no encryption guarantees. Sensitive content — API keys accidentally pasted, private logs, config snippets — lives indefinitely on someone else’s infrastructure.

A self-hosted pastebin gives you:

• Zero-knowledge encryption — the server stores ciphertext it can’t decrypt
• Auto-expiration — pastes self-destruct after a set time
• No tracking — no ads, no analytics, no data mining
• Full control — your data, your retention policy, your access rules

The Full Ranking

1. PrivateBin — Best for Security

PrivateBin is the gold standard for self-hosted encrypted text sharing. All encryption happens in the browser — the server stores only ciphertext and can never read your pastes. The decryption key is in the URL fragment (after the #), which browsers never send to the server.

How it works: You paste text → browser encrypts it with AES-256-GCM → sends ciphertext to server → server returns a URL → the key is appended after # → recipients decrypt in their browser. The server is mathematically incapable of reading the content.

Pros:

• Zero-knowledge encryption by design
• Burn-after-reading option (paste self-destructs on first view)
• Configurable expiration (5 minutes to never)
• Password protection on top of encryption
• Discussion/comment threads on pastes
• Syntax highlighting for code
• No database required (filesystem storage)
• No JavaScript dependencies from CDNs

Cons:

• No file sharing (text and images only)
• No URL shortening
• No user accounts or authentication
• Paste size limits tied to PHP config

Best for: Sharing sensitive information — credentials, logs, configs, private notes. The zero-knowledge model means even a server compromise doesn’t expose paste contents.

2. MicroBin — Best Lightweight All-in-One

MicroBin combines a pastebin, file sharing, and URL shortener into a single 10 MB Rust binary. No database, no complex dependencies — just a single container that handles everything.

What makes it stand out: MicroBin does three things that usually require three separate tools. Need to share a text snippet? Paste it. Need to share a file? Upload it. Need a short link? Create one. All from the same clean interface.

Pros:

• Pastebin + file upload + URL shortener in one tool
• Tiny footprint (~10 MB binary, ~20 MB RAM)
• No database (filesystem storage)
• Syntax highlighting
• Optional encryption
• Configurable paste expiration
• Read-once pastes (burn after reading)
• API for programmatic access

Cons:

• Encryption is server-side (not zero-knowledge like PrivateBin)
• Smaller community than PrivateBin
• Less mature (newer project)

Best for: Homelabs that want one tool for all sharing needs. If you don’t need zero-knowledge encryption, MicroBin’s versatility is hard to beat.

3. Opengist — Best for Code Snippets

Opengist is a self-hosted GitHub Gist alternative. Every snippet is a Git repository — you can clone, push, and version-control your pastes. Syntax highlighting for 250+ languages, user accounts, and both public and private snippets.

Pros:

• Git-backed (clone/push snippets)
• 250+ language syntax highlighting
• User accounts with OAuth support
• Public, unlisted, and private snippets
• Embed snippets in other pages
• API compatible with GitHub Gist

Cons:

• No encryption
• Heavier than PrivateBin or MicroBin
• Requires user accounts (no anonymous pasting by default)

Best for: Development teams sharing code snippets internally. The Git backend means snippets are versioned and can be cloned like any repo.

How We Evaluated

We prioritized security, simplicity, and Docker deployment. PrivateBin’s zero-knowledge encryption is unmatched for security-sensitive use cases. MicroBin’s combination of features in a tiny package makes it the most practical general-purpose option. Opengist fills the code-sharing niche with Git integration.

Frequently Asked Questions

How does zero-knowledge encryption work in PrivateBin?

When you create a paste, your browser generates a random AES-256-GCM encryption key, encrypts the content locally, and sends only the ciphertext to the server. The encryption key is placed in the URL fragment (the part after #) — browsers never send URL fragments to the server in HTTP requests. The recipient’s browser downloads the ciphertext and decrypts it using the key from the URL. The server mathematically cannot read paste contents, even if compromised. This is the same model used by end-to-end encrypted messaging apps.

Can I share files with a self-hosted pastebin?

MicroBin supports file uploads alongside text pastes — you can share documents, images, archives, or any file type with configurable size limits. PrivateBin supports image attachments but not arbitrary file uploads. Opengist handles code files through its Git-backed snippet system. For heavy file sharing needs, consider pairing your pastebin with a dedicated file sharing tool like FileBrowser or ProjectSend.

Are burn-after-reading pastes truly deleted?

Yes. Both PrivateBin and MicroBin delete the paste from the server immediately after the first view. In PrivateBin’s case, the encrypted ciphertext is removed from storage — since the server never had the decryption key, the content is irrecoverable. This is useful for sharing one-time credentials or sensitive information. Note that the recipient could still copy the content before the page closes, so burn-after-reading protects against server-side persistence, not recipient-side copying.

How much server resources does a self-hosted pastebin need?

Very little. MicroBin uses approximately 20 MB of RAM and is a single 10 MB Rust binary. PrivateBin runs on PHP and uses about 30 MB of RAM. Opengist is slightly heavier at 50 MB due to Git integration. All three run comfortably on the smallest VPS available or a Raspberry Pi. Storage depends on paste volume and retention settings — with auto-expiration enabled, storage stays bounded. A typical personal or small-team pastebin uses less than 1 GB of disk over years of use.

Can I use a self-hosted pastebin for team collaboration?

Opengist is the best option for teams — it supports user accounts, OAuth authentication (GitHub, GitLab, OpenID Connect), and private/unlisted/public snippet visibility. Snippets are Git-backed, so team members can clone and version-control shared code. PrivateBin and MicroBin are designed for anonymous, ephemeral sharing — no user accounts or access control. For team use with PrivateBin, put it behind an authentication proxy or Authelia to restrict access to your team.

How do I integrate a self-hosted pastebin with my workflow?

MicroBin and Opengist both provide APIs for programmatic paste creation. You can pipe command output directly to your pastebin from the terminal using curl. Opengist’s API is compatible with GitHub’s Gist API, so existing Gist tools and extensions work with it. For PrivateBin, community CLI tools like pbincli let you create encrypted pastes from the command line. Common integrations include CI/CD pipelines sharing build logs, scripts sharing diagnostic output, and chat bots creating pastes for long messages.
