Clipboard History IO is an open-source browser extension that securely tracks and manages everything you copy, storing your complete clipboard history locally on your device. Unlike traditional clipboard managers, this privacy-first solution ensures your copied data never leaves your computer unless you explicitly choose to sync via the optional cloud feature.

The extension addresses a common frustration that content creators, developers, and knowledge workers face daily: losing important copied text after accidentally copying something else. With Clipboard History IO, every snippet you copy is automatically saved and searchable, eliminating the anxiety of permanent data loss and the need to constantly switch between applications to recopy information.

Built with performance as a core priority, the extension delivers a remarkably fast and responsive experience. Users can access their clipboard history instantly using keyboard shortcuts, making it seamless to retrieve any previously copied item without disrupting their workflow. The interface has been carefully optimized to load quickly even with thousands of saved items, ensuring the tool enhances rather than hinders productivity.

What distinguishes this clipboard manager from competitors is its transparent security model. Being completely open source means users can verify exactly how their sensitive data is handled. The default local-only storage ensures passwords, personal information, and confidential text remain private on your machine.

Common Questions

Is my clipboard data secure?

Yes, all data is stored locally on your device by default. The open-source codebase allows you to verify the security implementation yourself, and cloud sync is entirely optional.

Can I use this across different browsers?

Clipboard History IO works on Chrome, Firefox, and Edge browsers, though clipboard history is browser-specific unless you use the Pro cloud sync feature.

How much storage does the extension use?

The extension includes built-in storage analytics so you can monitor usage. Most users find even thousands of clipboard items use minimal disk space.

Does it work offline?

Absolutely. The extension is fully functional offline and doesn't require an internet connection unless you're using the cloud sync feature.
