Zeltro

Zeltro is a desktop development platform designed for building and running applications directly on your computer. Key features include: * Use your existing large language model (LLM) subscriptions or API keys (e.g., Claude, ChatGPT, OpenRouter) * Integrate free local language models * Pay providers directly without Zeltro markup or credits * Create custom applications from descriptions or choose from 214 pre-built templates * Keep all code and data on your local machine This platform eliminates unnecessary costs by connecting directly to your chosen language model provider, ensuring you only pay their standard rates. With essential setup pre-configured, Zeltro helps reduce token consumption, allowing your chosen model to focus its resources on application development rather than boilerplate code or environmental plumbing. This optimized approach means more efficient development and lower operational expenses for your projects. Zeltro is ideal for individual developers, hobbyists, and small teams looking for a cost-effective, private, and efficient way to build applications. It supports a wide range of uses, from developing utility scripts and personal tools to creating more complex applications, all while maintaining complete control over your data and development environment. It's free for personal use and compatible with Linux, Mac, and Windows.
