About Zapbox
One door to every small utility you reach for — convert, dev, text, image, AI, remote, calc and more. Instant, zero setup, local-first, zero-knowledge encryption for the vault tools.
Principles
- Instant, zero setup — no signup, no install, every tool one step away.
- Local-first — most tools run in your browser; nothing leaves your device unless noted.
- Zero-knowledge — the 2FA vault & Password Vault encrypt locally; the server stores only ciphertext.
- Native + curated — we build the core tools and point to the best external options in Resources.
