Description

caveman is a bare-bones Claude Code TUI client, dependency-light and built for blazing-fast terminal coding.

Bare-bones TUI — No webview, no Electron, pure terminal experience that boots in an instant
Native Claude Code integration — talks to Anthropic's Claude Code with multi-turn context preserved
Minimal dependencies — only standard library, tiny footprint and low runtime overhead
Fast session switching — run multiple Claude Code sessions in parallel, hotkey-jump between them
Streaming responses — token-by-token streaming so long tasks show progress live
Extensible — plug in MCP tools and custom commands through a simple interface

💡 Running Claude Code on headless servers with no GUI

💡 Switching between multiple agent sessions in a large monorepo with keyboard-only control

💡 Latency-sensitive workflows where millisecond TUI startup matters

💡 Embedding Claude Code into existing terminal-first workflows (tmux, Kitty, WezTerm)
