Everything you need

Built for solo developers who value simplicity and security.

Military-grade encryption

AES-256-GCM with PBKDF2 key derivation. Your master password never leaves the browser.

Lightning fast

No sign-up, no sync, no waiting. Open and use instantly. Everything runs locally.

7 built-in generators

JWT secrets, UUIDs, API keys, passwords, and more. Save directly to projects.

One-click export

Export to .env, .envrc, or settings.json. Perfect for Claude Code.

Project organization

Group keys by project. Search, filter, archive. Keep your secrets organized.

Auto-lock & clipboard clear

Configurable idle timeout and automatic clipboard clearing after copying secrets.

Claude Code integration

Built for the way you work

Claude creates a Stripe key via MCP. KeyVault opens with the value pre-filled. You confirm. Done.

Prefill from MCP

Claude creates a key via Stripe, Cloudflare, or any MCP tool, then navigates your browser to a special URL. The vault auto-opens a pre-filled "Save key" modal. The secret never appears in your chat.
