Beat online queues with parallel browser instances.
One browser in the queue means one shot. QueueBoost launches multiple isolated, real browser instances in parallel — each independently queuing against your target URL — to multiply your chances of landing near the front.
Configure and go.

All instances queue in parallel
QueueBoost spins up each browser independently. Each one joins the queue as a real, separate visitor.
More instances. Better odds.
Parallel execution
Launch as many isolated browser instances as you want, all running simultaneously.
Real browser behavior
Each instance uses a real browser — not a headless scraper — reducing detection risk.
Per-instance proxy support
Route each browser through a unique HTTP proxy for greater distribution and reduced fingerprinting.
Configurable instance count
Set exactly how many browsers to launch. Scale up or down based on your target queue.
Low overhead
Designed for stability and speed. Instances are lightweight and launch fast.
Local-first & private
Everything runs on your machine. No data leaves your device.
