Byoky lets you share your token budget with friends, your team, or anyone building cool stuff — without exposing your keys.
It's Thursday. Your Anthropic limit resets on Monday. Your buddy hasn't touched his. Byoky lets him share — no keys, no accounts, no friction.
Pick a provider, set a budget cap, share the link. They redeem it in their wallet — your API key never leaves yours.
Their prompts hit your wallet, which forwards them to Anthropic using your key. They get tokens. You keep control.
One click kills the gift. Budget caps enforce limits automatically so nobody burns through your quota by accident.
Get a free token gift from the token pool, or plug in your existing Claude Pro/Max subscription. Either way, zero API credits, zero card on file — just a 5-minute setup.
Log in with your own keys. Byoky brings Bring-Your-Own-Key to the apps you already use — no more subscriptions, no more lock-in. Pick an app below to see what it looks like.
Create apps and websites by chatting with AI.
Running on your own keys · unlimited prompts

Integrate with any AI provider using their native SDK. Just swap in Byoky's fetch — keys never touch your app.

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.

});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.
Live preview — click Connect, approve in the wallet, watch the chat stream. Keys never leave your device.
One approval, then every request streams through the wallet — your keys never touch the page.
An app written for one provider hot-swaps to any other. The translation layer rewrites the call on the fly.
No extension? Scan a QR with the Byoky app — your phone becomes the relay. Same approval, same chat.
Share a budget-capped link to anyone. They redeem it in their wallet — your API key never leaves yours.
Add the Byoky extension to Chrome or Firefox — or grab the iOS or Android app. 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.
Works with any AI provider
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.
Move an app from a Claude group into a GPT group — the wallet translates requests on the fly. Anthropic ↔ OpenAI ↔ Gemini ↔ Cohere. No code changes.
Scan a QR code with the Byoky iOS or Android app. Your keys proxy through your phone. Works on any browser, any computer.
