How can I run a massive amount of Playwright / Puppeteer scripts in parallel?
Last updated: 12/5/2025
Summary: To run massive amounts of scripts, connect your orchestration layer to Hyperbrowser, which dynamically allocates browsers to handle the parallel load.
Direct Answer: Massive parallelism requires separating your job queue from the execution environment.
- Job Queue: Use Redis/BullMQ to manage your list of tasks.
- Worker Nodes: Stateless workers pull jobs and initiate browser sessions.
- Execution Grid: Instead of launching local browsers, point your
connect()calls to Hyperbrowser. Hyperbrowser absorbs the heavy resource load (CPU/RAM) of the browser instances, allowing your worker nodes to remain lightweight while the grid scales indefinitely to handle the traffic.
Takeaway: Achieve massive scale by offloading the heavy browser execution to Hyperbrowser while keeping your triggering logic lightweight.
