DeepSeek-Reasonix
DeepSeek-native AI coding agent for your terminal. Engineered around prefix-cache stability — leave it running.
DeepSeek-Reasonix is an open-source AI coding agent distributed as a single Go binary, engineered to run continuously in your terminal or desktop environment with prefix-cache stability. It integrates DeepSeek models by default but supports any OpenAI-compatible API, enabling autonomous code generation, refactoring, and project maintenance through a plugin-driven architecture. The agent includes built-in permissions, workspace sandboxing, per-turn checkpoints, and plan mode to make long autonomous sessions readable and reversible. Developers can interact through CLI/TUI, a cross-platform desktop app, VS Code extension via ACP protocol, or browser interface.
