Running Dozens of Antidetect Browsers in Parallel Without Losing Sync
We break down grouped vision analysis, status recovery, and concurrency controls that keep large browser batches moving as one system.
Apr 1, 2026Operational note
Parallelism breaks down when pages diverge and slow profiles drift out of sync. The winning pattern is grouped analysis, bounded concurrency, and recovery logic that treats the batch as one coordinated system instead of isolated tabs.
Sample flow
// Bounded parallel run
await browser_list();
await browser_parallel_navigate({ url: "https://target.example" });
await browser_parallel_vision_analyze_grouped({ maxConcurrency: 12 });
await browser_status();
await browser_parallel_wait_for({ text: "Dashboard", timeoutMs: 10000 });
