Rusty

A coding agent that never leaves your terminal. Rusty is a single 12 MB binary that pairs with you right where you work — fast, private, and entirely yours. No telemetry. No cloud lock-in. No bloat.

terminal

curl -fsSL rustycli.com/install | sh

Note

Rusty verifies the download with a checksum before it runs. Prefer to inspect first? Pipe the script to a file and read it — it’s ~40 lines of plain shell.

What you get

• Context-aware edits across your whole tree — file read/write/edit, unified diff patches
• A sandbox with approvals — tiered permission model with per-tool classification
• Readable diffs before any change lands
• Bring your own model — Xiaomi MiMo, Kimi, OpenAI, DeepSeek, Ollama, or any OpenAI-compatible API
• Built-in tools — bash, regex search, glob, web fetch, sub-agent spawning, task management
• Auto-compaction — three-tier system that keeps long conversations under the context window
• Session persistence — save, resume, and name sessions across restarts

Run modes

Full terminal UI with streaming, markdown rendering, permission prompts, and slash commands. This is the default.
