A secure browser wallet for AI API keys. Users own their keys. Developers build for free. No API costs, no key management — just ship.
Stop worrying about API bills killing your project. Your users connect their own AI keys through Byoky — you get the full power of Claude, GPT-4, Gemini, and 12 more providers without spending a cent on infrastructure.
Indie dev? Startup? Side project? It doesn't matter. If your users have API keys, you have a product. No billing integration, no usage caps, no margin pressure.
The Byoky MiniApp Creator turns your idea into a working app — powered by your own AI keys. Push to GitHub in one click. Zero cost.
Open MiniApp Creatoror npx create-byoky-app to scaffold locally · npm install @byoky/sdk to add to an existing project
Works with official SDKs from Anthropic, OpenAI, Gemini, Mistral, and 11 more providers. Just swap in Byoky's fetch.
Full SSE streaming support through the extension proxy. No special handling needed.
Your server makes LLM calls through the user's browser via WebSocket. Keys never leave the extension — even server-side.
The Byoky Bridge lets CLI tools and desktop apps route through the wallet via a local HTTP proxy. Keys stay in the extension.
Let users share token access without sharing API keys. Relay-backed with budget caps, expiry, and instant revocation.
import Anthropic from '@anthropic-ai/sdk';
import { Byoky } from '@byoky/sdk';
const byoky = new Byoky();
const session = await byoky.connect({
providers: [{ id: 'anthropic', required: true }],
modal: true, // built-in connect UI with QR code
});
// Use the native Anthropic SDK — keys never exposed
const client = new Anthropic({
apiKey: session.sessionKey,
fetch: session.createFetch('anthropic'),
});Add the Byoky extension to Chrome, Firefox, or Safari. Set a master password to encrypt your vault.
Paste API keys or add a Claude setup token. Everything is encrypted locally with AES-256-GCM. Multiple keys per provider.
Visit any Byoky-enabled app. Approve access in one click. Your keys stay in the vault — always.
Share token access without sharing your API key. Set a budget, generate a gift link, and revoke anytime. Relay-backed — zero key exposure.
Security isn't a feature — it's the entire point.
Keys encrypted with PBKDF2 (600K iterations). 12-character minimum with real-time strength meter. Web Crypto API — no dependencies.
API keys never leave the extension process. Apps receive temporary session tokens. The extension proxies every request.
Every API request is logged with the app origin, provider, status, and timestamp. Complete visibility into credential usage.
Set token allowances per app — total or per provider. The proxy enforces limits so no app can overspend.
Share token access with anyone — your API key stays in your wallet. Requests relay through you. Budget-capped with instant revocation.
Export your vault as an encrypted .byoky file with a separate backup password. Import on any device.
No cloud. No telemetry. No tracking. Everything is stored on your device, encrypted behind your master password.
15 providers supported. Bring credentials from any of them.
Connect any browser to your Byoky mobile wallet via QR code.
No browser extension needed. The web app shows a pairing code, you scan it with the Byoky iOS app, and your keys proxy through your phone. Works on any browser, any computer. Keep the app open while using the web app.
const session = await byoky.connect({
providers: [{ id: 'anthropic' }],
useRelay: true,
modal: true, // built-in connect UI with QR code
});
// Works exactly the same as extension modeUse your Byoky wallet as the key provider for OpenClaw.
The OpenClaw plugin connects through the Byoky Bridge — a local HTTP proxy that routes every API call through your extension. Your keys never leave the wallet, even when OpenClaw makes requests from the CLI.
Run OpenClaw in the cloud. Keys stay on your device.
Deploy OpenClaw on Railway, Fly.io, or any cloud provider and connect it to your Byoky wallet via the relay. Your server never sees your API keys — no environment variables, no secrets management, no leaked .env files.
