What is ex_ratatui?

ExRatatui brings Rust's ratatui terminal UI library to Elixir through seamless Rustler bindings, letting you build rich TUIs like dashboards and task managers without blocking the BEAM VM. It handles widgets for text, lists, tables, gauges, and blocks, plus layout splitting, event polling for keys/mouse/resizes, and full styling with RGB colors. Drop it into Elixir GitHub projects or Phoenix apps for interactive CLIs that feel native.

Why is it gaining traction?

Among Elixir GitHub trending projects, it stands out with precompiled NIF binaries—no Rust toolchain needed—and OTP-supervised apps using LiveView-style callbacks for mount/render/handle_event. Non-blocking DirtyIo polling keeps your Elixir processes responsive, and headless testing verifies renders in CI. Pairs naturally with Ecto or Ash for data-driven UIs, unlike pure Rust TUIs that ditch BEAM concurrency.

Who should use this?

Elixir CLI tool builders crafting system monitors, Nerves dashboards, or task managers with SQLite CRUD. Phoenix devs wanting terminal prototypes, or GitHub Elixir LangChain experimenters needing interactive prompts. Ideal for Linux admins tracking CPU/memory via BEAM stats, without JavaScript bloat.

Verdict

At 20 stars and 1.0% credibility, it's early but promising—excellent docs, examples, and tests make it prototype-ready. Grab it for Elixir terminal experiments; watch for more widgets before production.
