🤖 Why EnvSeal for AI Coding?

The reality of AI-powered development: project explosion

Working with Claude Code, Cursor, Gemini CLI, or Windsurf? You know the drill:

• 🚀 Today: 3 new demos
• 🎯 Tomorrow: 5 more repos
• 📂 Each one: .env, .env.dev, .env.prod

Then what happens?

• 💔 Migration Pain: Switching machines? The hardest part isn't code—it's "where are all those .env files?"
• 🔀 Sync Chaos: Updated DATABASE_URL in project A, forgot about project B
• ⚠️ Leakage Risk: AI screenshots, logs, and shares easily expose secrets
• 🚫 Onboarding Nightmare: New developer clones in 30 seconds, spends 3 hours hunting for credentials

EnvSeal's Solution:

Scan repos → Normalize .env → Encrypt with SOPS → Unified Git vault → One-command recovery

📖 What is EnvSeal?

EnvSeal is a CLI tool that helps you manage .env files across multiple repositories with end-to-end encryption. It scans your projects, normalizes environment files, and syncs them to a Git-backed vault using SOPS encryption.

Key Benefits:

• 🔒 Secure: SOPS + age encryption (modern, battle-tested)
• 📦 Centralized: One vault for all secrets across unlimited projects
• 🔍 Safe Diffs: Key-only diffs never expose values
• 🔄 Version Control: Full Git history for audit and rollback
• 🚀 Simple: One command to sync everything
• 💻 Multi-Device: Restore entire dev environment in minutes

• 🔐 Secret Rotation: Git history tracks "who changed what key and why"

🆚 How EnvSeal Compares

Most encrypted-dotenv tools manage one repo or run as a hosted service. EnvSeal's niche is the opposite: many local repositories, one self-hosted Git vault, no server, no account.

	EnvSeal	dotenvx	SOPS (alone)	dotenv-vault	Doppler / Infisical
Multi-repo, one central vault	✅ scans N repos	❌ per-repo	❌ manual	❌ per-repo	✅ (hosted)
Encryption	SOPS + age	built-in	SOPS + age/KMS	proprietary	hosted service
Needs a server / account	❌ no	❌ no	❌ no	✅ yes	✅ yes
Storage	your Git repo	your repo	your repo	their cloud	their cloud
Key-only diffs (no values)	✅	❌	❌	❌	➖
One-command machine restore	✅ pull	❌	❌	➖	➖
Shareable key-only HTML report	✅ report	❌	❌	❌	➖
Cost	free / OSS	free / OSS	free / OSS	freemium	paid tiers

Pick EnvSeal if you have many small projects (the AI-coding reality) and want one encrypted, Git-versioned vault you fully own — no SaaS, no lock-in.

⚡ Quick Start

📋 Complete First-Time Setup (Beginner-Friendly)

Step 1: Create Your Secrets Vault Repository

1. Go to GitHub and create a new private repository

   • Repository name suggestions: secrets-vault or my-secrets
   • ⚠️ Must be Private
   • Don't add README, .gitignore, etc. (create empty repo)

2. Clone it locally:

   # Replace USERNAME with your GitHub username
   # Replace secrets-vault with your repository name
   cd ~/Github  # Or wherever you keep your code
   git clone [e-mail]:USERNAME/secrets-vault.git
   

Step 2: Locate Your "Projects Root Directory"

This is the folder that contains all your projects, for example:

~/Github/                    ← This is your "root directory"
├── my-api/                 ← Project 1 (has .env files)
├── my-web/                 ← Project 2 (has .env files)
├── my-worker/              ← Project 3 (has .env files)
└── secrets-vault/          ← Your vault repo you just created

Step 3: Install and Initialize EnvSeal

Continue with the steps below 👇

Prerequisites

# macOS
brew install age sops

# Verify installation
age-keygen --version
sops --version

Installation

# Install with pipx (recommended)
pipx install envseal-vault

# Or with pip
pip install envseal-vault

# Verify
envseal --version

Initialize

# Navigate to your "projects root directory" (the folder containing all your projects)
cd ~/Github  # Replace with your actual directory, e.g., ~/projects or ~/code

# Run initialization
envseal init

During initialization, it will:

1. ✅ Generate an age encryption key
2. 🔍 Scan current directory for all Git repositories (finds my-api, my-web, etc.)
3. 📝 Create configuration at ~/.config/envseal/config.yaml
4. 🗂️ Ask for your vault path (enter: ~/Github/secrets-vault)

Sync Secrets

# Push all .env files to vault (encrypted)
envseal push

# Commit to YOUR secrets vault (the private repo you created)
cd ~/Github/secrets-vault  # Your vault repo, NOT the envseal tool repo
git add .
git commit -m "Add encrypted secrets"
git push

Check Status

envseal status

Output:

📊 Checking secrets status...

my-project
  ✓ .env       - up to date
  ⚠ .env.prod  - 3 keys changed

api-service
  + .env       - new file (not in vault)
  ✓ .env.prod  - up to date

Update Changed Secrets (Interactive)

# Interactively select and update changed secrets
envseal update

# Only show changes for specific environment
envseal update --env prod

The update command will:

1. Scan all repositories for changed .env files
2. Show an interactive selection menu
3. Let you choose which repos to update
4. Push selected changes to the vault
5. Show next steps for git commit/push

Browse the Vault (list / report)

Get an overview of every project's secrets — key names only, decrypted values are never shown, kept, or written anywhere.

# Terminal overview — every project, every env file, every key name
envseal list

# Static HTML dashboard — safe to share, opens with no server
envseal report                       # writes ./envseal-report.html
envseal report -o ~/envseal-report.html

The HTML report is a single self-contained file (no network, no server):

• Stat cards — project / key / env-file / environment counts
• Sticky search that filters by project name or key name
• One collapsible card per project, with environment badges and key chips
• Click-to-copy envseal pull commands for restoring each environment
• Light / dark theme toggle

Because it contains key names only — never values — the report is safe to commit, share with teammates, or drop into a wiki.

🚀 New Machine? Restore Everything in 10 Minutes

Just 4 steps:

1. 📋 Copy age private key (from password manager)
2. 📦 Clone your secrets vault repository
3. 🔧 Install EnvSeal: pipx install envseal-vault
4. ⬇️ Pull secrets: envseal pull <project> --env <environment> --replace

See detailed steps in the "Multi-Device Setup" section below 👇

🔐 Security

Age Key Management:

• Private key: ~/Library/Application Support/sops/age/keys.txt (macOS), ~/.config/sops/age/keys.txt (Linux), ~/AppData/Local/sops/age/keys.txt (Windows) (NEVER commit!)
• Public key: Stored in vault/.sops.yaml (safe to commit)

Backup Your Private Key:

# Display full key file
cat ~/Library/Application\ Support/sops/age/keys.txt

# Save to password manager (1Password, Bitwarden, etc.)

Linux/Windows users: use the OS-specific key path listed in Age Key Management.

⚠️ Critical: Losing your private key = permanent data loss!

Vault Repository Best Practices:

• ✅ Keep vault repository private (even though files are encrypted)
• ✅ Enable branch protection and require PR reviews
• ✅ Use GitHub's secret scanning push protection
• ✅ Backup private key in password manager

See SECURITY.md for complete security model.

🌍 Multi-Device Setup

Two repositories you need to know:

• 📦 EnvSeal tool: chicogong/envseal (this repo - install via PyPI, no need to clone)
• 🔐 Your secrets vault: USERNAME/my-secrets-vault (your private repo for encrypted .env files)

On a new machine:

1. Copy your age key from backup:

   mkdir -p ~/Library/Application\ Support/sops/age/
   nano ~/Library/Application\ Support/sops/age/keys.txt
   # Paste the 3-line key file (created, public key, private key)
   chmod 600 ~/Library/Application\ Support/sops/age/keys.txt
   

   Linux/Windows users: use the OS-specific key path listed in Security.

2. Clone YOUR secrets vault and install EnvSeal tool:

   # Clone YOUR vault (NOT the envseal tool repo)
   git clone [e-mail]:USERNAME/my-secrets-vault.git ~/Github/secrets-vault
   
   # Install EnvSeal tool from PyPI
   pipx install envseal-vault
   envseal init
   

3. Pull secrets:

   envseal pull my-project --env prod --replace
