Colabb Terminal — The Future of Command Line

Colabb is a high-performance terminal emulator built from scratch in C++ using GTK3 and VTE. It integrates Artificial Intelligence directly into the shell experience, offering context-aware suggestions, error explanations, and natural language command generation through its unique “Totem” system.

Key Features

• 🚀 Native Performance: Built with C++ for near-instant startup and minimal footprint (<30MB vs 400MB Electron).
• Non-blocking Inference: AI queries execute in sidecar threads (std::async), ensuring zero impact on shell responsiveness during network latency.
• Memory Efficiency: Limited scrollback buffer (Ring Buffer) to guarantee a predictable memory footprint.
• Stable Core: Built on top of libvte (Gnome Terminal engine), isolating experimental AI logic from shell stability.
• 🤖 Totem AI: Invoke AI assistance with ? or get automatic error analysis.
• 🧠 Context Awareness: The AI “reads” your previous commands and output to provide relevant help.
• 🎨 Visual Profiles: Customizable themes and fonts per tab.
• ⌨️ Hybrid Autocomplete: Smart tab-completion that blends shell paths with AI suggestions.
