Started March 2026 · Preview for macOS
I was using AI to build apps for myself and my family, often with private data on my own computer. Writing the code got faster, but setting up each app still took work: configure AI providers, store credentials and deploy it. Even a small change meant going back to the terminal and deploying again.
I built AppJuice so I could build an app, use it and change it in the same place. Apps run on my computer and keep their data there, without a separate deployment. They share the AI providers and credentials I set up once, and I can add an agent to an app when it needs one.

Building and using apps
- Run apps as you build them. Each app has its own interface and saved data. Changes appear in the running app without a deployment step.
- Make changes while using an app. Open Tweak mode and ask the builder agent to make a change.
- Add agents to an app. Give them tools, skills and context. The SDK includes UI components for conversations, model selection, approvals, attachments and generated files. You can also define how multiple agents work together in code.
- Choose your AI providers. AppJuice supports 50+ provider integrations, including OpenAI, Anthropic, Google, DeepSeek and MiniMax, plus local models through Ollama or LM Studio. You can choose models for each AI feature.
- Use AI services from any app. Shared APIs and tools cover text, images, transcription, speech, music, video and web search, using the providers you configure.
- Share apps. Install apps from the Juicery, or share an app package without your private app data or provider credentials.
- Connect from other devices. Use Tailscale to access apps running on your computer.
- Publish a website. With a cloud host configured, ask the builder agent to deploy a static site or an app with a backend.
Apps run locally by default. When an app uses cloud AI, it sends the context needed for the request to your selected provider. File and tool access follows the platform’s permissions and your approvals.
