[Beta Version] Send.win Evolves: From Lightweight Extension to Full Cloud Browser Access

Send.win is evolving from a browser extension to a full Cloud Browser Access platform.

This shift overcomes the constraints of Manifest V3 extensions—like service workers shutting down and disrupting long-running connections—by hosting all functionality in the cloud.

With Send.win Cloud Browser, you’ll have uninterrupted access to every multi-login, session management, and proxy assignment feature you love, delivered via secure, server-powered virtual browsers.

Existing extension users can continue to enjoy the legacy version at extension.send.win, while newcomers can explore the new Cloud Browser offering (with a 7-day trial for €1) at send.win/pricing

Why the Change?

Manifest V3 Limitations

• Service Worker Lifecycle: Under Manifest V3, background scripts run as service workers that browsers can unload during idle periods, interrupting persistent connections and real-time data streams.

• MV2 Deprecation: Chrome and Edge are phasing out Manifest V2. Staying on MV2 risks losing support and security updates, while MV3’s restrictions limit critical extension capabilities.

Impact on Users

• Power users experienced fragmented workflows when bulk session creation, real-time syncing, or proxy assignments were disrupted.

• Managing local tabs and dealing with sandboxing inconsistencies led to lost productivity and feature gaps.

What’s New in Send.win Cloud Browser

• Full Feature Parity: Every multi-login, session timer, bulk session, and proxy-assignment capability from the extension is available in the cloud.

• Server-Side Session Isolation: Each session runs in its own isolated virtual browser, removing reliance on local resources and avoiding browser sandbox limitations.

• Seamless Sharing & Sync: Share live sessions with teammates via secure links; session state is stored and synchronized server-side for smooth cross-device continuity.

• Enhanced Security: Cloud sessions run on dedicated virtual browsers, protecting your passwords and cookies from local machine exposure.

• Automatic Updates: Benefit from instant feature releases and security patches without needing to reinstall or update an extension.

Pricing & Trial

• Legacy Extension: Continues to be free forever at extension.send.win.

• Cloud Browser Version: Visit send.win/pricing for full details. Pricing increase: Reflects the higher infrastructure, bandwidth, and maintenance costs required to host isolated cloud browsers under heavy load.

• 7-Day Trial: Available for €1, giving you a risk-free opportunity to explore the cloud environment.
