Crystal Ultra-Efficient Personal AI Assistant - 2MB Binary

Autobot is an ultra-efficient personal AI assistant written in Crystal, producing a mere 2MB binary with minimal memory footprint. Combining Ruby-like syntax elegance with native code performance, Autobot is designed for environments where every kilobyte and milliwatt matters. GitHub: https://github.com/crystal-autobot/autobot Developer: crystal-autobot (Community Open Source) License: MIT Platforms: Linux, macOS, Windows, BSD Key Innovation: Autobot demonstrates that AI agents can be incredibly small and efficient - at just 2MB binary size and 30MB RAM usage, it brings AI to the most resource-constrained environments.

Core Philosophy: "Elegance meets efficiency - small code, big capabilities"---

Why Autobot?

2MB Binary: Incredibly small footprint for an AI agent.

Crystal Performance: Ruby-like syntax with C-like speed.

Type Safety: Compile-time type checking for reliability.

Energy Efficient: Minimal power consumption for edge devices.

FAQ

Is 'Autobot' free to use?

Yes, 'Autobot' is free and open source ('MIT' license). You only pay for AI model API costs if using external models.

What are the system requirements for 'Autobot'?

'Autobot' requires '30MB RAM' of RAM minimum. Runtime: 'Native binary (Crystal)'. It runs on Windows, macOS, and Linux.

Can I self-host 'Autobot'?

Yes. 'Autobot' is open source ('MIT') and can be self-hosted on your own hardware. Clone the repository from GitHub and follow the installation guide.

How does 'Autobot' compare to OpenClaw?
