MarsLinker

MarsLinker helps you temporarily connect data between different browser clients and provides refined control.

MarsLinker – Effortless Site Data Sharing Across Browsers MarsLinker is a lightweight browser extension designed to temporarily transfer site-specific browsing data between different browser clients, profiles, or devices. Instead of relying on continuous background sync, it uses a secure code-and-password model for controlled, on-demand sharing. The popup interface is clean and divided into two core sections: Subscription (Receive): Enter a code and password to fetch and apply site data instantly. Publication (Send): Create a share plan for a specific site with custom options like expiration times, usage limits, and sensitive data filtering. MarsLinker operates on a strict "per-site permission" model rather than asking for blanket access to all websites. It requests domain access only when needed and can automatically clear old site remnants before applying new data to ensure a clean state transition. Key Features: Two-Way Workflow: Dedicated Subscription and Publication modes for intuitive sending and receiving. Per-Site Authorization: Grants host permissions only when explicitly needed for a specific site. Flexible Share Controls: Customize access codes, expiration periods, download limits, and data exclusion rules. Clean State Application: Optional auto-cleanup of target site caches before applying new data. How It Works: Open the MarsLinker popup and select Subscription or Publication. To Receive: Enter the code and password, authorize the domain when prompted, and apply the site data. To Send: Select a site, configure your share settings, and generate the encrypted package. Manage: View, update, or remove your active subscriptions and share plans anytime. Privacy: Transferred site data is encrypted and used strictly for user-initiated sharing functions. MarsLinker operates on demand without continuous tracking or personal data collection.
