Features

Everything you need,
nothing you don't

Built for developers who are tired of hunting for API keys across 10 different browser tabs.

🎯
Smart Site Detection
Visit platform.openai.com? API Locker instantly shows your OpenAI keys. Goes to Stripe dashboard? Your Stripe keys appear. Zero manual searching.
🏢
Provider Logos & Grouping
Each key is tagged with its provider's logo and name. 32+ providers supported — OpenAI, Anthropic, AWS, Stripe, GitHub, Supabase and more.
⚡
One-Click Copy
Keys masked by default for security. Click Copy and the full key goes straight to your clipboard — no popup, no searching, no friction.
📦
Multiple Keys Per Provider
Label your keys (Production, Development, Client A...) and store as many as you need for the same provider. Switch between them instantly.
📅
Expiry Reminders
Set an expiry date on any key. Get warned 14 days before it expires — and see expired keys highlighted in red so nothing slips through.
💾
Import & Export
Back up your entire vault to a JSON file. Restore it on any device instantly. Migrate between computers without re-entering everything manually.
How It Works

Up and running in 60 seconds

1
Install & Set Master Password
Add API Locker from the Chrome Web Store. Choose a strong master password — this is the only password you'll ever need to remember.
2
Add Your API Keys
Select a provider, paste your key, add a label like "Production" or "Client A". Optional: set an expiry date. Done in 5 seconds per key.
3
Auto-Suggest on Every Site
Visit any supported API dashboard and your keys appear automatically. Click Copy. Paste. That's it. Never search for an API key again.
Security

Zero-knowledge.
Zero-cloud.

Your keys never leave your device. We never see them — not even encrypted.

🔐
AES-256-GCM Encryption
Every key is encrypted with AES-256-GCM, the same standard used by governments and financial institutions.
🧂
PBKDF2 Key Derivation
Your master password goes through 100,000 iterations of PBKDF2 before becoming an encryption key. Brute-force resistant.
💻
100% Local Storage
Everything stays in chrome.storage.local on your machine. No servers, no accounts, no internet connection required.
🚫
No Telemetry, No Tracking
We collect zero data about you or your keys. No analytics, no usage tracking, no crash reports sent anywhere.
