Envault

Envault is a secure, modern vault application built with Next.js, Supabase, and Tailwind CSS. It provides a robust authentication system and a sleek user interface for storing and managing sensitive information.

Features

• Bank-Grade Security: AES-256-GCM encryption with master/data key hierarchy and automatic key rotation.
• Project Workspaces: Organize secrets into distinct projects for better management.

• Team Collaboration: Secure project sharing with strict Role-Based Access Control:
  • Owner: Full administrative control (Rename, Delete, Manage Team).
  • Editor: Active contributor (Read/Write secrets, request to Share).
  • Viewer: Read-only access to variables.
• Secure Authentication: Powered by Supabase Auth for robust user management, including Passkey support for passwordless, biometric login.
• Modern UI/UX: Built with Tailwind CSS, Shadcn UI, and Framer Motion for a premium experience.
• Interactive 3D Elements: High-performance 3D visuals powered by React Three Fiber.
• Keyboard First: Navigate efficiently with fully customizable, conflict-free hotkeys.
• Responsive Design: Fully responsive layout that works seamlessly on desktop and mobile.
• Dark Mode Support: Built-in support for light and dark themes.

• Native Vercel Integration: Link Vercel projects, map environments, and sync secrets directly into Vercel env storage for serverless runtime compatibility.
• Real-time System Status: Monitor system health, active incidents, and historical uptime with a dedicated status page.
• Dedicated Support Page: Integrated support features directly within the app to help users manage troubleshooting options efficiently.
• Comprehensive Documentation: Integrated docs site with guides, API reference, and CLI documentation.

CLI

Envault natively supports the Model Context Protocol (MCP), so AI coding assistants like Claude Desktop, Cursor, and RooCode/Cline can pull and push your secure environments effortlessly.

# Automatically configure your AI clients (Global & Local Workspaces)
envault mcp install

# Or install strictly for the current workspace
envault mcp install --local

Installation

macOS & Linux (Universal)

curl -fsSL https://raw.githubusercontent.com/DinanathDash/Envault/main/install.sh | sh

macOS (Homebrew)

brew tap DinanathDash/envault
brew install --formula envault

Homebrew cask installs are deprecated. If you installed via cask, migrate with:

brew uninstall --cask dinanathdash/envault/envault
brew install --formula envault

For more details, check out the CLI Documentation.

Local Testing

Envault local development now uses portless with HTTPS hostnames.

npm install -g portless

To use the Envault CLI with the local development server, set the ENVAULT_CLI_URL environment variable:

export ENVAULT_CLI_URL="https://envault.localhost:1355/api/cli"
envault login

For one-command envault run local app startup, prefer hosted API fetch-first behavior by not setting ENVAULT_CLI_URL/ENVAULT_BASE_URL.

Security Architecture

Envault uses a hybrid encryption model to ensure maximum security:

1. Master Key: A 32-byte key stored in environment variables, used solely to encrypt/decrypt Data Keys.
2. Data Keys: Unique keys for encrypting actual data. These are stored encrypted in the database.
3. Key Rotation: Data keys can be rotated. The active key is cached in Redis for high performance without compromising security.
4. AES-256-GCM: Industry-standard authenticated encryption for all secrets.

Getting Started

Follow these steps to get the project running locally.

Prerequisites

• Node.js 18+ installed
• A Supabase project set up

Installation

1. Clone the repository

   bash

   git clone https://github.com/dinanathdash/envault.git
   cd envault
   

2. Install dependencies

   bash

   npm install
   # or
   yarn install
   # or
   pnpm install
   # or
   bun install
   

3. Environment Setup

   Copy the example environment file:

   bash

   cp .env.example .env.local
   

   Open .env.local and add your Supabase credentials:

   env

   NEXT_PUBLIC_SUPABASE_URL=your-project-url
   NEXT_PUBLIC_SUPABASE_ANON_KEY=your-anon-key
   
   # Generate a secure key: node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
   ENCRYPTION_KEY=your-64-char-hex-key
   
   SUPABASE_SERVICE_ROLE_KEY=your-service-role-key
   
   UPSTASH_REDIS_REST_URL=your-upstash-url
   UPSTASH_REDIS_REST_TOKEN=your-upstash-token
   
   # Used for securely signing and verifying frontend API mutations (POST, PUT, DELETE, PATCH)
   NEXT_PUBLIC_API_SIGNATURE_SALT=your-secure-random-hmac-secret
   
   

4. Run the development server

   bash

   npm run dev
   

   Open https://envault.localhost:1355 with your browser to see the result.

Optional: Native Vercel Integration Setup

If you plan to use native Vercel sync (recommended for Vercel serverless runtimes), add these variables:

VERCEL_CLIENT_ID=your_vercel_oauth_client_id
VERCEL_CLIENT_SECRET=your_vercel_oauth_client_secret
VERCEL_REDIRECT_URI=https://your-domain.com/api/integrations/vercel/callback
VERCEL_WEBHOOK_SECRET=your_vercel_webhook_signing_secret
NEXT_PUBLIC_VERCEL_INTEGRATION_INSTALL_URL=https://vercel.com/<team-or-user>/~/integrations/envault

Use production URLs in production. Do not use ngrok or localhost callback URLs outside local development.

5. Test Email Configuration (Optional)

   To verify that your Resend API configuration is working, you can send a test email to yourself:

   bash

   npm run test:email -- your-email@example.com
   

Monorepo Setup Map

This repository contains multiple publishable/runtime components. Use this map when cloning and contributing.

First-time contributor flow

1. Clone and install root dependencies:

git clone https://github.com/dinanathdash/envault.git
cd envault
npm install

2. Copy env file and configure required keys:

cp .env.example .env.local

3. Install package-local dependencies for publishable subpackages:

cd src/lib/sdk && npm install
cd ../../.. && cd mcp-server && npm install
cd ..

4. Validate everything in one pass:

npm run lint
npm run test:all
npm run build

Package Publishing + Workflows

npm packages

• SDK: @dinanathdash/envault-sdk (source: src/lib/sdk/)
• MCP: @dinanathdash/envault-mcp-server (source: mcp-server/)

GitHub Actions workflows

• CLI release workflow: .github/workflows/publish.yml
• SDK publish workflow: .github/workflows/publish-sdk.yml
• MCP publish workflow: .github/workflows/publish-mcp.yml

Each package versions independently via semantic-release when changes occur in its own folder:

• CLI tags: v<version>
• SDK tags: sdk-v<version>
• MCP tags: mcp-v<version>

This keeps SDK and MCP release streams decoupled from CLI version bumps.

Local prepublish checks

npm run sdk:check
npm run mcp:check

Manual publish commands

npm run sdk:publish
npm run mcp:publish

Version and Update Commands
