Yes. Notepad++ is a Windows-only desktop program, but this is a free browser-based Notepad++ alternative that works the same way for most everyday tasks: syntax highlighting for many languages, line numbers , multiple tabs , find & replace, code folding, and one-click formatting. It runs on any device — Windows, Mac, Linux, Chromebook, iPad or Android — with no install and no sign-up , which the desktop app can't do. (This tool is independent and not affiliated with the Notepad++ project.) Yes. The editor shows line numbers in the gutter and supports multiple tabs , so you can keep several files or notes open at once. Each tab autosaves separately and reopens exactly where you left off. You also get bracket matching, code folding, and find & replace. A browser-based code editor is a text editing tool that runs directly in your web browser without requiring any software installation. Unlike traditional desktop editors like Visual Studio Code, Sublime Text, or Notepad++, this approach offers immediate accessibility from any device with a web browser. You can access your code from work computers, laptops, tablets, or any machine without setup time. The editor features instant auto-save functionality using localStorage , meaning all your notes and code persist between visits on the same device. This online notepad is ideal for quick coding snippets, prototyping, learning new languages, writing scripts, or temporary documentation before integration into your main project. Yes, auto-save is enabled by default and operates continuously. Your code is saved to your browser's localStorage on your local device—it is never uploaded to any external server, maintaining complete privacy and security. This means your sensitive code, passwords, or confidential notes remain exclusively on your device. The auto-save mechanism triggers as you type, so no data is lost even if your browser crashes or your connection drops. Data syncs automatically across all tabs on the same browser, allowing seamless work across multiple windows. Your data persists until you manually clear browser history or localStorage , giving you reliable backup on your device itself. This free code editor supports an extensive range of programming languages with powerful syntax highlighting. Coverage includes JavaScript, Python, JSON, HTML, CSS, XML, SQL, KQL (Kusto Query Language), Markdown, Ruby, PHP, Java, C, C++, C#, Go, Rust, and many others. Syntax highlighting is powered by the industry-standard CodeMirror library, providing accurate color-coding for keywords, strings, comments, and functions. Additional features include automatic bracket matching, code folding for complex functions, line numbering, and intelligent indentation. This makes the editor suitable for developers, data scientists, and students working across multiple programming languages and frameworks. Absolutely—no account is required whatsoever. Start typing immediately upon opening the tool. This zero-friction approach provides a completely distraction-free experience perfect for developers who want to focus purely on coding without account setup, password management, or authentication delays. The tool is designed specifically for rapid access and immediate productivity, making it ideal for quick coding tasks, interview preparations, algorithm solutions, or temporary script development without the overhead of account creation. Export your work easily with a single click. Save straight back to a file on disk with Ctrl+S , download a copy, or copy everything to your clipboard. Markdown can be exported to a styled .html file or printed to PDF. This makes it simple to integrate with your development workflow, version control systems like Git, or share with teammates and collaborators. Yes, complete offline functionality. Once the editor loads, all features work entirely offline without any internet connection. Your code saves locally to browser storage, and all editing capabilities function perfectly in offline mode. This makes it perfect for airplane mode, unreliable connectivity situations, or privacy-conscious development scenarios where you want zero data transmission to external servers. While full IDE replacements like VS Code offer extensive features, this browser-based editor excels in accessibility and simplicity. Zero installation required, instant access from any device, built-in syntax highlighting, line numbers, find-and-replace functionality, and automatic local storage make this ideal for rapid coding tasks, learning, and prototyping. For quick edits, interview coding, or when you need a lightweight solution without IDE overhead, this editor provides an optimal balance of power and simplicity. Yes — autosave is built in. Every keystroke is saved to your browser's localStorage as you type, and each tab reopens exactly where you left off the next time you visit on the same device and browser.

Absolutely. This is designed to be the fastest blank page on the internet — open it and start typing with no login, no signup, and no install .

Keep one tab open and it becomes your always-available scratch space. Yes. Paste your JSON, select the JSON language, and press Shift+Alt+F to pretty-print and indent it — a handy lightweight online JSON formatter .

Press Ctrl+F to open a Notepad++-style find & replace popup with match case, whole word, regular expressions (including capture groups like $1 in replacements), and wrap-around search. All matches are highlighted live with a running "3 of 17" counter, F3 / Shift+F3 jump to the next or previous match, and Replace All handles the whole document in one undo step. Yes. Open both texts in two tabs and hit the ⇆ Diff button (or View → Compare Tabs) to get a side-by-side comparison with added, removed, and changed lines colour-coded — changed lines even highlight the exact characters that differ. Scrolling is synchronised between the panes and a summary shows how many lines were added, removed, or modified. Everything runs locally in your browser, so it's a private online diff tool too: nothing is uploaded. Yes. Press Ctrl+Shift+P to open a command palette with fuzzy search over every command in the editor — file operations, search, view toggles, and all the text transforms.

Yes — the Transform menu is a full text toolbox: sort lines A→Z, Z→A or numerically, remove duplicate lines , remove blank lines, reverse lines, UPPERCASE / lowercase / Title Case, trim trailing whitespace, Base64 encode/decode , URL encode/decode , and JSON minify. Each transform applies to your selection if you have one, or the whole document if you don't. Yes, in Chrome and Edge. Click 📁 Folder (or File → Open Folder) and pick a folder on your computer — a file tree sidebar appears, just like a desktop editor.

Yes. Alt+Shift+T reopens recently closed tabs (up to the last 20). And under File → Sessions you can save your current set of tabs under a name — "work", "scratch", "blog drafts" — and load it back any time. Sessions are stored in your browser's local storage, so they stay private and survive restarts. The interface is available in 12 languages : English, Nederlands (Dutch), Español (Spanish), العربية (Arabic), Bahasa Indonesia, Français (French), Português (Portuguese), Русский (Russian), 日本語 (Japanese), Deutsch (German), हिन्दी (Hindi) and 中文 (Chinese).

It runs on a real local language model via WebLLM and WebGPU that downloads once to your browser and then works completely offline. Nothing you write is ever sent to a server — it's the same private, local approach as the standalone free browser AI tool. Only once, to download the model you pick (roughly 350 MB to 2.2 GB depending on size and quality). After that it runs fully offline on your device's GPU — no account, no API key, no usage limits. It needs a desktop browser with WebGPU support (Chrome, Edge or Brave); if that's unavailable, the panel shows a warning and links to the mobile/WASM AI tool instead.
