ByoKey (Bring Your Own Key) gives you complete freedom and transparency over your AI workflow. Connect your personal API keys from top providers like OpenAI, Anthropic, Google Gemini, or leverage OpenRouter to unlock hundreds of models in a sleek, lightweight interface. Stop paying for expensive monthly AI subscriptions. Pay strictly for what you use directly to the providers—ByoKey is and will always remain 100% free.

New in 1.2 - Connect with OpenRouter: instead of typing an API key, sign in to OpenRouter – or create a free account there. ByoKey picks up the key automatically. - Start for free: with a free OpenRouter account you can use free models – with a daily limit, and provided your account allows their data policies. If your account has no credit yet, ByoKey shows only free models; you can change this in the model list. - New first steps: on first launch you choose between "Connect with OpenRouter" and "Enter your own API key". The button is also in Settings under OpenRouter. - Six more providers: Anthropic (Claude) directly, Scaleway and IONOS with processing in the EU (according to the providers), Vercel AI Gateway, Requesty and DeepInfra. - Custom server: connect ByoKey to Ollama, LM Studio or any other OpenAI-compatible server – for example on your Mac on the same network. No API key needed. - Your own prices: if a provider lists no price for a model, enter it yourself – touch and hold the model in the list. The cost display uses it. - More providers now deliver their prices with the model list: xAI, Together AI, Vercel, Requesty and DeepInfra. - For providers outside the EU, the consent screen now also explains the risks of the transfer. ByoKey therefore asks for your consent to these providers once more. - Clearer messages when free models reach their daily limit or are not enabled in your OpenRouter account. - Faster: the model list, sending and long chats respond more smoothly. - Fixed: content reports by e-mail now use the app's language.
