Codus is a privacy-first, offline developer toolkit that merges everyday utilities with AI-powered assistance — all running locally, without telemetry or dependency on the cloud.
Built with Rust (Tauri), React + TypeScript, and Llama.cpp 2, Codus delivers a fast, secure, and intelligent workspace for developers who value control and efficiency.
⚙️ Under Active Development — coming soon for Windows, macOS, and Linux.
Codus is engineered for local-first privacy and secure workflows.
- All tools and AI models run entirely offline.
- No data collection, analytics, or telemetry — ever.
- Optional cloud models (OpenAI, Anthropic, etc.) are explicitly opt-in.
- Fine-grained privacy settings for total transparency.
Codus is your private AI-powered workbench, not a cloud service.
- 🦀 Rust (Tauri) — secure and memory-safe native runtime.
- ⚛️ TypeScript + React — clean, modular desktop UI.
- 🧠 Llama.cpp 2 — efficient local inference for open-source models.
- Run local LLMs with Llama.cpp 2
- Import
.ggufmodels or fetch directly from the Hugging Face Hub - Configure remote APIs (OpenAI, Anthropic, custom endpoints)
- Unified model selector for instant context switching
- Local and cloud AI chat interface
- Persistent, context-aware sessions stored locally
- Prompt templates and “Ask AI” integration
- Multi-model testing and comparison
