What Is an Online Browser?
An online browser is a web browser that runs entirely in the cloud, allowing you to browse the
internet through a remote server rather than your local device. You access it through your existing browser – the
cloud handles all processing, rendering, and network connections while streaming the visual output back to you.
Online browsers eliminate the need for local software installation and provide inherent privacy benefits since
websites interact with the cloud server, not your personal device. This makes them invaluable for privacy-conscious
users, multi-account managers, and anyone needing secure browsing environments.
How Online Browsers Work
The Technical Architecture
- Cloud instance: A browser runs on a remote server in a data center
- User connection: You connect via your regular browser or app
- Input forwarding: Clicks, keystrokes, and scrolls sent to the cloud
- Remote rendering: Websites rendered on cloud hardware
- Video streaming: Visual output streamed back to your screen
- Session management: State preserved between connections
Key Technical Components
- Rendering engine: Full Chromium or Firefox running remotely
- GPU acceleration: Cloud GPUs handle graphics rendering
- Video encoding: H.264/VP9 for low-latency streaming
- WebSocket connection: Real-time bidirectional communication
- Storage layer: Persistent cookies, bookmarks, and downloads

Frequently Asked Questions
Is an online browser free?
Some services offer free tiers (Browserling has 3-minute sessions). Full-featured online browsers with persistent
sessions and unique fingerprints typically require a subscription. Send.win offers competitive pricing with full
features.
Is using an online browser legal?
Yes. Online browsers are legitimate privacy and security tools. They’re widely used by enterprises for security and
individuals for privacy. The legality depends on what you do while browsing, not the tool itself.
