Our verdict on nook

nook is an open-source, terminal-native IDE for Go development, distributed as a single Go binary. It is aimed at developers who work in a terminal, over SSH, in tmux, or inside containers and want AI-assisted editing alongside core project navigation. The feature set includes file editing, project search, an embedded terminal, Git inline blame, gopls diagnostics, inlay hints, reference search, and workspace symbol search. That makes nook a focused fit for Go developers who prefer a compact, keyboard-oriented environment over a general-purpose graphical IDE.

Its platform and ecosystem fit are central to the product. nook supports terminal, SSH, tmux, and container workflows, with remote development listed as supported. The default language server is gopls, providing live diagnostics and inlay hints, while Git adds inline blame. For AI-assisted work, nook connects to the Claude Code CLI and provides inline editing, ghost-text inline completion, and a Multi-file Composer that produces planned diffs. Together, these integrations keep editing, code navigation, version-control context, and terminal work in one environment without moving away from a Go-centered workflow.

The standout feature is the combination of AI editing and multi-file composition inside a terminal-native Go tool. Planned diffs give the Composer a defined change-review step, while workspace reference and symbol search support navigation across a project. nook should appeal to Go developers who value open-source software, gopls feedback, and remote terminal workflows. It is a narrower choice for users who want a graphical interface, a multi-language IDE, or a broader development workflow beyond its documented editing, navigation, search, Git, terminal, and language-server capabilities.
