What agentty is

agentty is a free, MIT-licensed, open-source coding agent delivered as a native C++26 single static binary for the terminal. It provides code completion, chat assistance, coding-agent features, codebase indexing, and terminal access. Built-in tools handle file operations, code search, shell and build commands, Git, web and documentation searches, and task delegation. Model choices include Claude, ChatGPT, GitHub Copilot, Kimi, hosted APIs, custom OpenAI-compatible endpoints, and local Ollama models. Ollama can run locally without an API key or cloud data transfer. Conversations persist as saved threads with durable cross-session memory. Linux and macOS sandbox shell and build calls by default, and filesystem tools stay within the launch workspace unless changed. Windows runs those calls unsandboxed. An SSH air-gap mode relays traffic to an agent on a host without direct internet access. agentty integrates with Zed through ACP and can serve or consume MCP tools.

Who it suits

agentty suits developers seeking a single-binary terminal coding agent, model choice, sandboxed commands, or SSH access to air-gapped hosts. It also fits users working with Zed, MCP, or local Ollama models.

What it does well

Free and MIT licensed
Supports multiple hosted and local model options
Persistent threads and durable memory
Sandboxed shell calls on Linux and macOS
Works with Zed and MCP tools

What to know first

Windows shell and build calls are unsandboxed
Android without root lacks shell sandboxing
Runs in the terminal as a coding agent
Air-gap mode trusts the remote host with tokens

Verdict

agentty combines terminal coding assistance, broad model compatibility, local Ollama use, and integrations such as Zed and MCP. Its sandbox behavior differs by platform, so users should account for those operating-system limits.
