A blazing-fast, modular, and extensible productivity hub built with Rust and Ratatui.
LaTUI (Launcher TUI) is more than just a simple application launcher. It’s an ultra-high performance terminal interface designed for sub-50ms latency, offering a unified, keyboard-centric workflow for everything from launching software to managing your clipboard and searching your filesystem.
Built with a Strategy-Pattern architecture, LaTUI is compositor-agnostic and uses a hybrid search engine combining O(m) Trie-based prefix filtering with Levenshtein typo tolerance and SQLite-backed frequency tracking.
- Extreme Performance: Built for speed with Rust, achieving <50ms startup and <10ms search latency.
- Intelligent Ranking: Learns your habits using SQLite to track usage frequency and recency.
- Modular Architecture: Every feature is a "Mode"—add or remove functionality with zero core logic changes.
- Hybrid Search Engine: Smart prefix matching + Damerau-Levenshtein typo tolerance.
- Modern Interface: Premium, responsive TUI with tabs, previews, and smooth layouts.
- Config-First: Fully customizable via
~/.config/latui/config.toml.
LaTUI is organized into specialized Modes, each optimized for specific tasks. Use Tab to switch between them instantly.
The core launcher experience. Index your .desktop files with keyword-aware search (e.g., search "browser" for Firefox). Features all-time frequency and recency boosting.
Apps mode also supports real icon-image rendering in terminals that expose image protocols (Kitty graphics / Sixel). In practice this means terminals like kitty and foot (with sixel enabled) can render app icon images; other terminals automatically fall back to text icons.
Search and navigate your filesystem at lightning speeds. Uses the high-performance ignore crate for traversal and includes text file previews.
A persistent shell command executor with history deduplication and fuzzy searching. No more searching through shell history; find it instantly in LaTUI.
Manage your clipboard history across Wayland (wl-clipboard) and X11 (xclip). Features persistent storage and privacy-aware 0600 file permissions.
A fast, keyword-searchable emoji picker. Copy any of the 240+ embedded emojis to your clipboard instantly with frequency-based sorting.
LaTUI follows a loosely coupled Strategy Pattern where the interaction between the UI and functionality is mediated by a common trait. This allows for massive extensibility and isolation of concerns.
For a deep dive into LaTUI's structure, performance considerations, and internal modules, please see our Architecture Documentation.
LaTUI is thoroughly customizable via ~/.config/latui/config.toml. You can configure colors, layouts, layout variants, modes, and keybindings.
