No signup. No cloud. Open source on GitHub.
⚠ The OneTab Data Loss Problem OneTab stores all saved tabs in Chrome's local extension storage — a volatile space that Chrome can wipe during updates, profile resets, or crashes. Reddit users on r/chrome and r/chrome_extensions have reported losing 847+ bookmarks without warning. Chrome 148 also introduced bookmark bar bugs that compound the problem. TabFlow solves this with local IndexedDB storage + automatic JSON export backups.

OneTab Pain Points

Migration Guide

How to Migrate from OneTab to TabFlow

Move all your saved tabs from OneTab to TabFlow in under 30 seconds.

1

Open OneTab and export your tabs

Click the OneTab icon in Chrome, then click "Export / share URLs" in the top-right corner. This opens a page with all your saved tab URLs in a plain text list. Select all (Ctrl+A) and copy (Ctrl+C).

2

Open TabFlow and paste your URLs

Go to selfloom.github.io/tabflow/app.html. Look for the import button or text area, then paste your copied URL list. TabFlow accepts URL lists, bookmark HTML exports, and JSON.

3

Let AI tag your bookmarks automatically

TabFlow reads each imported URL and title, then assigns tags automatically. You can review and edit tags anytime. All your data stays local — nothing is uploaded.

4

Export a backup for safety

Once your bookmarks are imported, click the export button to save a JSON backup. Store it somewhere safe. Unlike OneTab, you now have a real safety net.

5

(Optional) Install the Chrome extension for new tab replacement

Install the TabFlow Chrome extension to replace your new tab page with your AI-organized dashboard. The web app works standalone too — you choose.

User Stories

What OneTab Users Are Saying

Real experiences from Reddit — paraphrased with source attribution.

I had 847 links saved in OneTab spanning two years of research. Chrome updated, and every single one vanished. No warning, no recovery option. Switched to TabFlow the same day — the auto-backup alone is worth it.

OneTab was great until it wasn’t. Lost about 300 tabs after a browser crash. Found multiple threads of people losing even more. TabFlow gives me the same one-click save without the anxiety of wondering if my data will still be there tomorrow.
Source: r/chrome_extensions, 2025
Chrome 148 messed up my bookmark bar and I almost lost everything again. That was the final straw. TabFlow’s standalone web app means I’m no longer dependent on Chrome’s fragile extension storage. Plus, the AI tagging actually saves me time instead of adding work.

FAQ

Frequently Asked Questions

Quick answers about TabFlow as a OneTab alternative.

Yes. TabFlow is a full OneTab replacement that not only saves your open tabs into an organized list, but also uses AI to auto-tag and categorize them. Unlike OneTab, TabFlow stores your data locally with a backup & export system, so you will never lose your bookmarks. TabFlow also works as a standalone web app without any extension.
OneTab stores all your saved tabs in Chrome’s local extension storage, which is limited and can be cleared unexpectedly. Chrome updates, profile resets, disk cleanup tools, and browser crashes can wipe this storage. Users on Reddit (r/chrome, r/chrome_extensions) have reported losing hundreds of bookmarks overnight. TabFlow avoids this by storing data in IndexedDB with automatic JSON export backups, and offers a standalone web app that works independently of any extension storage.
Open OneTab and click “Export / share URLs” to copy all your saved tab URLs as a list. Then paste them into TabFlow’s import box — TabFlow accepts URL lists, bookmark HTML exports, or JSON. Any tabs you already have open in Chrome will be detected automatically when you open TabFlow. The migration takes under 30 seconds.
No. TabFlow is completely free forever. There are no paid plans, no premium tiers, and no paywalls. The AI auto-tagging, backup, dark mode, and standalone web app are all included at zero cost. TabFlow is also open source on GitHub.
Yes. TabFlow has a standalone web app at selfloom.github.io/tabflow/app.html that works in any browser with zero installation. You can bookmark the page, set it as your homepage, or use it alongside the Chrome extension. This is a major advantage over OneTab, which requires the extension to function.
Raindrop.io is a full-featured bookmark manager with a generous free tier, but its AI features require a Pro subscription, and it has no standalone web app option. Workona is a workspace manager for teams with a limited free tier. TabFlow is the only option that combines AI auto-tagging, zero data loss guarantees, a standalone web app, and a permanently free open-source license — all without requiring an account or cloud subscription.
TabFlow stores all your bookmarks and tabs locally on your device using IndexedDB and localStorage. Nothing is uploaded to any server. There are no accounts, no cloud sync, and no telemetry. You can export your data as JSON at any time for backup. This local-first architecture means your bookmarks cannot be lost due to server outages, company shutdowns, or cloud storage limits.
The TabFlow standalone web app works in Chrome, Firefox, Edge, Brave, Arc, and Safari. The Chrome extension is available for Chromium-based browsers (Chrome, Edge, Brave, Arc). The standalone app is extension-free and works on any modern browser including mobile browsers.
