API Key Manager | HTML5 Management Tool

Live Demo: API Key Manager | HTML5 Management Tool Live Demo

API Key Manager is a secure, client-side API key organizer built entirely with pure HTML, CSS, and JavaScript. No server, no database, no backend setup - just open the file and it works instantly in any modern browser. It lets developers, freelancers, and teams store, organize, search, and protect all their API keys in one place.

API Key data is stored in your browser’s localStorage and never leaves your device unless you export it manually. No accounts, no subscriptions, no internet dependency after the first load.

Product Overview

API Key Manager is a robust and intuitive tool designed to streamline the management of your API keys. It eliminates the need for complex server setups or external dependencies, providing a secure and self-contained solution for key storage and organization.

Modern Design and User Experience

The API Key Manager boasts a clean, modern interface built with HTML5, CSS3, and Vanilla JavaScript. It features a responsive design that adapts seamlessly to various screen sizes, ensuring a user-friendly experience on desktops, tablets, and smartphones.

Main Features and Capabilities

• Core Key Management:

  • Add, Edit & Delete Keys: Manage your keys with ease, including setting names, values, categories, vaults, notes, tags, and expiry dates.
  • Search & Filter: Instantly locate keys using keyword searches, filter by category or vault, and sort by date or name.
  • Bulk Actions: Select and delete multiple keys simultaneously for efficient management.
  • Key Strength Meter: Automatically assess the security of each key, rating it as Weak, Fair, Good, or Strong.
  • Auto-Hide Keys: Key values are masked by default and auto-hide after a configurable timeout for enhanced security.
  • Expiry Dates: Set expiry dates per key; overdue warnings appear automatically to prevent unauthorized access.
  • Tags: Label keys with relevant tags such as Production, Development, Staging, Test, etc., for better organization.
  • Activity Log: Track the last 50 actions, including adds, copies, deletes, and exports, for auditability.

• Security:

  • AES-256-GCM Encryption: Encrypt all stored keys using a master password with the browser's native Web Crypto API (PBKDF2 key derivation with 200,000 iterations + AES-GCM). No third-party crypto libraries involved.
  • PIN / Password Lock Screen: A full-page lock overlay appears on every app load; supports both numeric PINs and full passwords.
  • 5-Attempt Lockout: A short lockout delay kicks in after 5 failed unlock attempts to prevent brute-force attacks.
  • Zero Server Communication: Keys are never transmitted over any network, ensuring maximum data privacy.

• Organization:

  • 8 Built-in Categories: Payment, Cloud, Social Media, Database, Analytics, AI/ML, Messaging, and Other.
  • Custom Categories: Add, rename, and delete your own categories from within the app; built-in ones are protected.
  • Vaults (Key Groups): Organize keys into named, color-coded vaults for project-level separation (e.g., "Client A", "My Startup", "Personal").

• Export & Backup:

  • Export to JSON: Create a full backup of all keys, including vault and category data.
  • Export to CSV: Open in Excel or Google Sheets; includes name, key value, category, vault, tags, strength, expiry, and notes.
  • Import from JSON: Restore from backup with Merge (keep existing keys) or Replace (overwrite) mode.

• PWA & Offline Support:

  • Progressive Web App (PWA): Install on desktop or mobile as a standalone app directly from the browser.
  • Full Offline Use: Service worker caches all app files on first load; works with zero internet after that.
  • Add to Home Screen: Works on Android (Chrome) and iPhone (Safari).

• User Experience:

  • Light & Dark Mode: Toggle between themes; preference is saved across sessions.
  • Fully Responsive: Works seamlessly on phones, tablets, and desktops.
  • Configurable Settings: Auto-hide delay, date format, confirm-delete prompts, usage count tracking, and more.
  • No Installation Required: No npm, no terminal, no build step; just upload and open.
