Amazon Q Developer CLI Review 2026

Terminal-based AI coding assistant from AWS with MCP server support for prompt and tool integrations.

Amazon Q Developer CLI mattered because it brought agentic AI assistance directly into the terminal, where a lot of serious engineering work still happens. Instead of treating the shell as a place to paste commands from a chatbot, Amazon Q Developer CLI offered a native command-line experience for code help, shell guidance, and AWS-oriented workflows. The official repository describes it as an agentic chat experience in the terminal, but the most important 2026 fact is the maintenance status: AWS now says the open-source project is no longer being actively maintained beyond critical security fixes and points users to Kiro CLI as the successor.

That transition changes how teams should evaluate it. If you want the newest product from this lineage, you should be looking at Kiro CLI. If you want an inspectable open-source reference for how a terminal AI assistant was built, this repository is still useful. The GitHub page also confirms supported installation paths including a macOS DMG, Homebrew, Ubuntu or Debian packages, and AppImage-based Linux installs. The codebase itself is Rust-based and dual licensed under MIT and Apache 2.0, which makes it useful for technical inspection and adaptation.
