Bitcoin TUI (Bitcoin Core Dev Tech, May 2026)

Bitcoin-tui is a small terminal user interface for a Bitcoin node, written in C++ on the FTXUI framework. The demo showed a dashboard, a mempool explorer with recent blocks, a peers view, and a tools tab including a raw-transaction broadcaster. Richer mempool.space-style transaction visualizations were judged possible via FTXUI's Canvas, within the limits of terminal rendering.

An unreleased version adds Lua scripting "tabs" so users can build their own views — a view-only wallet with a new QR-code visual was demoed — and Lua is noted as well-suited to users who generate visualizations with LLMs. The project plans to rewrite its current C++ tabs as Lua and expose UI components to the scripting layer. It interacts with the node over RPC today (benefiting from Bitcoin Core's RPC allowlisting); extending to IPC is not objected to but not yet planned. The next release awaits a better-documented, more stable FTXUI release.
