The problem

Every AI app builder
hits the same three walls.

You've built something brilliant. Then the same reality hits every single time.

Wall 01
💾

Data lives in the browser

localStorage and IndexedDB work until they don't. Clear cache, switch browser, use another device — it's gone. Your users can't sync and your app feels like a toy.

Wall 02
🔓

API keys sit in plain sight

Your Anthropic key is right there in your source code. Anyone who opens DevTools can find it, copy it, and drain your account dry. It's not a question of if — it's when.

Wall 03
🔧

Auth is a full-time job

Firebase, Supabase, Clerk — great products built for a different customer. Configuring any of them is an afternoon of docs, stitching services, and debugging session tokens.

The solution

Three features.
One script tag.

Everything you need to take an AI app from prototype to production — without a backend engineering degree.

★ The Vault — killer feature

AI Key Vault & Relay

Register your Anthropic, OpenAI, or Gemini API key with Vaultly — once, AES-256 encrypted, server-side. We issue you a scoped Relay Key per app.

Your real API key never touches the browser. Ever. Enforce per-user rate limits. Monitor token usage. See exactly who's calling the AI and what it costs.

// Before Vaultly — key exposed 😬
const res = await fetch("api.anthropic.com", {
  headers: { "x-api-key": "sk-ant-LIVE_IN_BROWSER" }
});

// After Vaultly — zero exposure ✓
const res = await Vaultly.ai.complete({
  relay: "rly_your_safe_key",
  model: "claude-sonnet-4-20250514",
  messages: [{ role: "user", content: prompt }]
});
Feature 02

Drop-In Auth

One script tag. Email/password and magic link login out of the box. Sessions that persist and sync across browsers and devices. No configuration, no schema, no OAuth headaches.

// That's it. Your app has real users.
<script
  src="https://cdn.vaultly.dev/v1.js"
  data-app="your-app-id"
></script>
Feature 03

Cloud Store

Schema-free key-value storage tied to each logged-in user. Works like localStorage — but it persists, syncs across every device, and survives a cache clear. No SQL, no migrations.

// Familiar API, real persistence
await Vaultly.store.set('my-data', data);
const d = await Vaultly.store.get('my-data');

// Syncs everywhere. Always. ✓
How it works

From zero to production
in under ten minutes.

We've cut every step that doesn't need to exist.

01

Create your app

Sign up and register your app in the Vaultly dashboard. Under 60 seconds.

02

Add the script tag

One line. Auth and storage are live immediately — zero configuration.

03

Vault your API key

Paste your AI key once. We encrypt it and issue your safe Relay Key.

04

Ship it

Real users, real data, real protection. Monitor everything from the dashboard.

Security first

Built for developers who can't afford to get hacked.

Vaultly was designed security-first, not security-bolted-on. Every architectural decision — from how we store keys to how we handle tokens — was made with breach scenarios in mind.

🔐

AES-256-GCM Encryption

Your API keys are encrypted with authenticated encryption. Even a full DB breach reveals nothing usable.

🔄

JWT Rotation + Reuse Detection

Short-lived access tokens. Refresh tokens rotate on every use. Reuse triggers automatic family invalidation.

🛡️

Rate Limiting at Every Layer

Brute force protection on auth, relay call limits per user, account lockout after failed attempts.

🕵️

Zero Key Exposure

Your real API key is decrypted in memory, used, then nulled immediately. It never leaves our server.
