About agentty
agentty is a terminal-native coding agent implemented in C++26 that provides a lightweight alternative to existing agent clients. It operates as a single static binary of 17.6 MB with millisecond cold-start times and no runtime dependencies such as Node or Python. The tool supports multiple model providers including Claude, ChatGPT, Copilot, Kimi, DeepSeek, Gemini, Grok, OpenAI, Groq, and local Ollama instances, allowing users to switch backends without restarting the session. agentty integrates with Zed via the Agent Client Protocol and supports one-command SSH air-gap execution for remote environments. It includes built-in sandboxing via bwrap or sandbox-exec, adjustable reasoning effort, image pasting, and a permission system with predefined profiles. The agent features Smart Mode for dynamic model routing, workspace-specific memory and skills, persistent threads, isolated subagents, and git-based checkpointing with rollback capabilities. Users can run shell commands interactively, mention files, search symbols, and access a command palette within the terminal interface.

Frequently asked questions about agentty
What is agentty and what does it do?
agentty is a terminal-native coding agent implemented in C++26 that provides a lightweight alternative to existing agent clients. It operates as a single static binary with millisecond cold-start times and no runtime dependencies, enabling users to interact with various model providers directly from the terminal.
Who is agentty designed for?
agentty is designed for developers and technical users who prefer working in a terminal environment and require a fast, dependency-free coding agent. It suits those who value performance, minimal footprint, and seamless integration with their existing workflows.
Does agentty support multiple model providers?
Yes, agentty supports multiple model providers including Claude, ChatGPT, Copilot, Kimi, DeepSeek, Gemini, Grok, OpenAI, Groq, and local Ollama instances. Users can switch between backends without restarting the session.
How does agentty ensure security and isolation?
agentty includes built-in sandboxing via bwrap or sandbox-exec, depending on the operating system. It also features a permission system with predefined profiles to control the agent's actions, ensuring safe and isolated execution of commands.
Can agentty be used in remote environments?
Yes, agentty supports one-command SSH air-gap execution, allowing users to run the agent on remote machines with no direct internet access. The agent relays bytes securely over SOCKS5-over-SSH with TLS pinning for end-to-end encryption.
How do I get started with agentty?
Getting started with agentty is simple: download the single static binary, make it executable, and run it directly in your terminal. No additional dependencies like Node or Python are required. Detailed installation instructions and documentation are available on the agentty website.
