NPP — Notepad++ Inspired Code Editor A fast, lightweight code editor that treats your unsaved work as sacred. Whether you're a professional developer, a student, or a tinkerer, NPP gives you the essentials to write and edit code — without the weight of a full IDE, and without ever fearing lost changes. NEVER LOSE YOUR WORK This is what makes NPP different. Every tab and every unsaved edit is continuously saved to disk in the background. Close the app, swipe it away, run out of battery, or let it crash mid-sentence — it doesn't matter. Reopen NPP and every tab is exactly where you left it, down to the last character you typed. No "Save?" dialogs, no warnings, no anxiety. Commit to a real file only when you're truly done. MULTI-TAB EDITING Work on many files at once with intuitive tabs. Spin up as many scratch tabs as you like — for quick notes, snippets, or full drafts — without touching your file system. Switch between them instantly. BUILT FOR BIG FILES A rebuilt editing engine keeps typing smooth and responsive even in very large files, where other mobile editors stutter. SYNTAX HIGHLIGHTING FOR 60+ LANGUAGES • Python, JavaScript, TypeScript, Dart, Vue • Java, Kotlin, Swift, Objective-C • C, C++, C#, Go, Rust, Assembly • Ruby, PHP, Perl, Lua, R • Elixir, Erlang, Haskell, Clojure, OCaml, F#, Julia • HTML, CSS, SCSS, JSON, XML, YAML, TOML • SQL, GraphQL, Protocol Buffers, Diff/Patch, LaTeX • Bash, PowerShell, Dockerfile, Makefile, nginx & Apache configs, .env • Markdown and many more VIEW & EDIT CSV AS A TABLE Open any CSV or TSV and see it as a clean spreadsheet with automatic delimiter detection. Tap a cell to edit it, and search across all cells with the matching cell highlighted — then switch back to raw text anytime. MORE THAN A PLAIN EDITOR • Live Markdown preview with clickable links • One-tap JSON formatting / beautify • Find & Replace with case-sensitivity and regular expressions • Automatic bracket matching FILE OPERATIONS • Open files from your device • Save, Save As, and export scratch tabs to real files • Automatic UTF-8 detection with fallback for legacy files • Open files directly from other apps MADE YOURS • Light, dark, and system themes • Toggle line numbers and word wrap • Adjustable font size • Custom status bar color SUPPORTED DEVICES NPP runs on phones, tablets, and desktop computers, adapting its layout to each screen size for a comfortable editing experience everywhere.
