Everything you need to code in the browser
Built on Monaco with a full editor toolkit — the features you'd expect from a desktop IDE, in a single tab.
Multi-Tab Workflow
Work across many files at once with a fast, keyboard-friendly tab bar and split navigation.
File Explorer
Virtual filesystem with folders, recent files, drag-and-drop, and quick open — built for 100k+ files.
Offline First
Full PWA — install once, work anywhere. Files persist in IndexedDB and sync when you reconnect.
Search & Replace
Blazing fast find, replace, regex, and case-sensitive search across every open file.
Diff & Compare
Side-by-side diff view to compare files, revisions, or paste-and-compare snippets.
Format Tools
Prettier-style formatters for JSON, HTML, CSS, JS, and more — one click, no configuration.
Dev Tools Panel
Base64, JWT decode, URL encode, hash generators, and everyday utilities baked in.
Themes & Fonts
Developer-friendly dark mode, light mode, and custom font sizes with JetBrains Mono.
Keyboard Shortcuts
modern shortcuts. Ctrl+S, Ctrl+F, Ctrl+Z — everything where you expect it.
Private by Default
Your code stays in your browser. No telemetry, no server-side storage.
Why NextNotePad?
Desktop editors are heavy. Online editors want your account. NextNotePad gives you the speed of a native editor and the reach of a URL — without asking for anything in return.
- Zero install — works in any modern browser
- Offline-first — your files stay yours
- Free and ad-free
