What is vnsh?

vnsh demo

Stop pasting walls of text into Claude. Pipe your logs, diffs, and images into a secure, host-blind URL. The server sees nothing. The data vaporizes in 24 hours.

# Pipe anything to vnsh, get a secure link
git diff | vn
# https://vnsh.dev/v/aBcDeFgHiJkL#R_sI4DHZ_6jNq6yqt2ORRDe9QZ5xQB6hIRLWHVFa8v8

Handles any context your AI needs:

🖼️ Screenshots — UI bugs, error dialogs, terminal output
📜 Logs — 5000+ lines of server errors (too long for copy-paste)
🔄 Git Diffs — Complex PR reviews, multi-file changes
📦 Binaries — PDFs, CSVs, config files, database dumps
🔧 Debug Context — Stack traces, environment dumps, crash reports

Philosophy

"Built for the ephemeral nature of AI workflows. Once your session is done, the data should be too."

Unlike Dropbox or pastebins, vnsh implements a Host-Blind Architecture with automatic vaporization:

Layer	What Happens
Encryption	AES-256-CBC encryption happens entirely on your device
Transport	Decryption keys travel only in the URL fragment (`#secret`) — never sent to servers
Storage	Server stores encrypted binary blobs — host-blind, no access to contents
Vaporization	Data vaporizes after 24 hours. No history. No leaks.

URL Structure (v2 — compact format)

https://vnsh.dev/v/aBcDeFgHiJkL#R_sI4DHZ_6jNq6yqt2ORRDe9QZ5xQB6hIRLWHVFa8v8jYCFqgQIbsRJrtJze_nL5
                  └────────────┘└────────────────────────────────────────────────────────────────────┘
                  12-char ID     64-char base64url secret (key+iv, never sent to server)

The v2 format reduces URL length by ~40% (from ~160 to ~95 characters). Legacy v1 URLs (#k=...&iv=...) are still fully supported.

Self-Hosting

vnsh runs on Cloudflare Workers with R2 storage. Deploy your own instance:

Prerequisites

Cloudflare account with Workers & R2 enabled
Wrangler CLI

Deploy

# Clone the repository
git clone https://github.com/raullenchai/vnsh.git
cd vnsh/worker

# Install dependencies
npm install

# Create R2 bucket
wrangler r2 bucket create vnsh-store

# Deploy
wrangler deploy

Configuration

Edit wrangler.toml to customize:

name = "vnsh"

[[r2_buckets]]
binding = "VNSH_STORE"
bucket_name = "vnsh-store"  # Your R2 bucket name

[[kv_namespaces]]
binding = "VNSH_META"
id = "your-kv-namespace-id"  # Create with: wrangler kv namespace create VNSH_META

API Reference

Security Model

What vnsh Protects Against

✅ Server Compromise — Even with full server access, attackers cannot decrypt blobs ✅ Database Leaks — Stored data is indistinguishable from random noise ✅ Traffic Analysis — No content-type information stored ✅ Subpoenas — Server operator cannot produce plaintext (doesn't have keys)

What vnsh Does NOT Protect Against

❌ URL Sharing — Anyone with the full URL (including #fragment) can decrypt ❌ Client Compromise — Malware on your device can intercept before encryption ❌ MITM on Upload Page — An attacker serving malicious JavaScript could intercept

Recommendations

Use vnsh over HTTPS only
Don't share full URLs in public channels (Slack, Discord, Twitter)
For maximum security, self-host the worker

Copy & paste — that's it

echo "hello" | npx vnsh

Quick Start

Option 1: Web Upload

Visit vnsh.dev, drag & drop a file, or paste text. Get an encrypted link instantly.

Option 2: CLI Installation

Zero-install (just run it):

echo "hello" | npx vnsh

NPM (global install):

npm install -g vnsh

Shell script (cross-platform: macOS, Linux, WSL, Git Bash):

curl -sL https://vnsh.dev/i | sh

CLI Usage

# Upload a file
vn secrets.env

# Pipe from stdin
cat crash.log | vn
docker logs app | vn
git diff HEAD~5 | vn

# Read/decrypt a URL
vn read "https://vnsh.dev/v/aBcDeFgHiJkL#R_sI4DHZ..."

# Custom expiry (1-168 hours)
vn --ttl 1 temp-file.txt   # expires in 1 hour

# Show version and help
vn --version
vn --help

Option 3: Claude Code (MCP Integration)

Native to Claude Code. Unlike Dropbox, vnsh has a first-party MCP server. Claude can "see" inside your encrypted links without leaving the terminal.

Create .mcp.json in your project root:

{
  "mcpServers": {
    "vnsh": {
      "command": "npx",
      "args": ["-y", "vnsh-mcp"]
    }
  }
}

Restart Claude Code after adding the config. Now Claude can:

Read vnsh links automatically when you paste them
Share large text outputs via vnsh_share tool
Share files (images, PDFs, binaries) via vnsh_share_file tool

Option 4: Zero-Install (Remote Servers)

No installation needed. Pipe anything from any server with just curl and openssl:

# One-liner: encrypt and upload from any machine
cat error.log | bash <(curl -sL vnsh.dev/pipe)
# https://vnsh.dev/v/aBcDeFgHiJkL#R_sI4DHZ_6jNq6yqt2ORRDe9...

# Works with any command
kubectl logs pod/crash | bash <(curl -sL vnsh.dev/pipe)
docker logs app 2>&1 | bash <(curl -sL vnsh.dev/pipe)
journalctl -u nginx --since "1 hour ago" | bash <(curl -sL vnsh.dev/pipe)

# Custom TTL (hours)
cat secrets.env | bash <(curl -sL vnsh.dev/pipe?ttl=1)

Perfect for SSH sessions, CI runners, Docker containers — anywhere you can't install tools.

Option 5: Chrome Extension

One-click encrypted debug bundles for AI. Share text, screenshots, and console errors directly from your browser.

Right-click any selected text → Share via vnsh
Cmd+Shift+D → AI Debug Bundle (screenshot + console errors + selected text + URL, all encrypted)
Hover over vnsh links on any page → see decrypted preview tooltip

Build from source or install from the Chrome Web Store (pending review):

cd extension && npm install && npm run build
# Load dist/ as unpacked extension in chrome://extensions/

See extension/README.md for full documentation.

Option 6: GitHub Action (CI/CD)

Debug CI failures with Claude in one click. When your CI fails, automatically upload logs and post a secure link to your PR.

- name: Debug with vnsh
  if: failure()
  uses: raullenchai/upload-to-vnsh@v1
  with:
    file: test.log
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

The action will post a comment to your PR:

🔍 Debug with Claude

CI logs uploaded securely. View Logs | Paste link to Claude for instant analysis
