The Simplest Checklist App That Doesn't Need an Account
Create checklists that save in your browser. No account, no cloud, no tracking. Just a list that's there when you come back.
The problem
Sometimes you just need a checklist. Not a project management tool with boards, sprints, and team collaboration. Not a note-taking app that wants your email before you can write anything down. Just a place to type a few items, check them off, and move on. Most checklist apps either require an account, sync to the cloud (meaning your grocery list lives on someone else's server), or take 10 seconds to load because they're built on a framework heavier than the task they're solving.
How it works
- Type an item and press Enter — it's added to your list immediately.
- Click to check off items — completed items get a visual strikethrough.
- Reorder items — drag them up or down to prioritize.
- Clear completed items — remove everything you've finished with one click.
Your list is saved to your browser's localStorage. That means it persists between page loads and browser restarts, but it never leaves your device. No server, no account, no sync. Close the tab, come back tomorrow, and your list is still there.
When to use this tool
Quick task lists for the day. A packing list before a trip. A deploy checklist you run through every release. A shopping list. Meeting action items. Anything where you need a simple, throwaway list that doesn't justify signing up for another app. It's also useful for situations where privacy matters — the data literally cannot be accessed by anyone but you.
Why I built it
I use checklists for deploy procedures, daily tasks, and quick errands. I didn't want to open Notion or Todoist for a five-item list I'd delete by end of day. And I definitely didn't want another app sending my task list to a server. localStorage is the perfect fit for throwaway, private lists.
Tips and reference
A note on localStorage: your data persists in the browser until you clear your browsing data or explicitly remove it. It's tied to the specific browser and device — if you open the tool in Chrome, your list won't appear in Firefox. It also won't survive clearing cookies and site data. For short-lived lists this is fine, but for anything you'd be upset to lose, copy it somewhere more permanent.
Built with vanilla HTML/JS. No frameworks, no backend, loads instantly.
