GSC Time Machine is a Chrome extension designed to extend the history of your Google Search Console data beyond the standard 16-month limit. This tool automatically fetches, backs up, and permanently stores your SEO data locally, allowing for long-term analysis without losing valuable historical insights. With its 'Local-First' architecture, the extension ensures that your data remains private and secure on your device without relying on external servers.

Key features of GSC Time Machine include unlimited history storage, automatic synchronization, and advanced visualization tools for analyzing trends over several years. Users can easily export their data to CSV or Google Sheets for further use. However, it's important to note that this extension can only preserve data from the installation date onward and cannot recover any data that Google has deleted prior to its use.
